Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.

Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.

It makes 7.72Mwh per year, worth $1000. Tight valley, tons of snow. We put that on the loan for 8 years, then get $1000 per year free money for 20 years or so. Biggest no brainer of all time.

Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)

Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.

> Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.

It would be worth including control of the people who vote for the politicians by direct investment such as when the oil producing Saudis bought the second largest stake in NewCorps which controls FoxNews controlling the content that influences voters. And, less than ethical control using bots on social media by Russia.

A lot of what influences "solar prices in the US" is controlled by foreign oil producing countries like Saudi Arabia and Russia controlling content and media consumed by American voters.


Here in California, they drastically cut back on the price that you get for solar powered electricity from homeowners. It used to be around $0.30/kWh at any time of day and now it's can drop to $0.00-$0.05/kWh during the day when the state is sunny. If you can afford to have a battery installed, the rates are far better as you can either run off the battery when rates are the highest in the evening, or you can export it back to the grid when prices are much higher.


The price is signaling that additional solar power production during the day isn't very useful; and additonal solar power production in the early evening when demand is high and the sun isn't shining and you need a battery system to have already been accumulating energy during the day is useful, albeit more expensive and complicated to build and run.


With falling battery prices this should be an addressable problem. Soak up the locally generated excess energy and sell it later in the day when the need is there. Electrical arbitrage seems like a win/win solution for the utilities their customers.


That’s because net metering is a transfer from people who can’t afford solar to the rich people who can. https://energyathaas.wordpress.com/2024/04/22/californias-ex...


Which is true. But it's a rug pull for people who spent money on their panels expecting an RoI. Were existing installations grandfathered in?


Yes, existing installations get 20 years of grandfathered rates [1].

Which makes it more of a ladder pull than a rug pull...

[1] https://www.sce.com/clean-energy-efficiency/solar-generating...


The first round of people paid way more for their solar panels though, and those higher prices helped bootstrap the industry. Should people who paid much less for panels get the same reward? I'm having trouble getting outraged about this, it seems to be incentives working exactly as they should.


I agree, and maybe my "ladder pull" comment comes off as too negative. Most early solar buyers were either in it for environmental reasons or for a modest return on investment. I don't think many were expecting a windfall.


That's fine. If we have enough X then stop paying people to build more X.


Late thought: we continue to reward those who built more X when we needed more X, and that's fine too.


Solar has become all about ROI these days just like home ownership has become an investment.


Residential solar is completely counter-productive right now in california. Just take a look at the CAISO price maps during the day when the sun is shining. There's so much power they are paying people to consume it. It's a negative force for grid stability. Getting paid for making the grid less stable is ridiculous. Until there is widespread battery storage or massively improved transmission and distribution systems grid-tied residential solar is a solution in search of a problem.


I agree wholeheartedly, and the technocrats are complicit with the GOP here.

It's funny how “free markets” keep producing the most expensive solar prices in the developed world. Don't get me started on Healthcare (I just moved back to the U.S. a couple years ago after 18 years in Canada, what a cluster*ck).

Oil and gas buy politicians, foreign oil money buys media influence, and social-media bots keep voters angry at the wrong targets.

Saudi capital helps shape the messaging, Russia helps amplify the noise, and Americans get stuck paying more for clean energy while being told it’s patriotic.

But hey, Make America Great Again, right?


If even a Democratically-led California is doing this, how can you point fingers at just the GOP? It's endemic to the system, and not restricted to just one party.


I just can’t with “both sides” when one side is increasingly becoming lawless and reckless.


Republicans are always trying to increase and protect oil subsidizes, cheer "drill baby drill", and have social media tools peddling their bs who are funded by foreign influence campaigns. The Democats may not be perfect, but they are much more likely to cut oil subsidies or at least subsidize solar and other renewables to balance. This is especially true as the next generation takes over by primarying the tepid fossils currently in office. Meanwhile, dear leader Dumpty likes to suggest windmills cause cancer because he doesn't like what they look like on the horizon of his golf dumps. Saying this is a "both sides" problem is laughable.


Fly over Texas and the California and compare the number of solar and wind installations you see.


Yup. 46.8 GW photovoltaic in California and 22.8 GW photovoltaic in Texas. Over twice as much PV in California even though they have higher standards for new construction in general than Texas does.


The US doesn't have a free market in either health care or electricity generation. An actual free market in solar power would probably result in more or less what we are seeing with the actual highly regulated market in electricity, namely extremely cheap prices for additonal solar energy in the middle of the day when the sun is shining, higher prices for additonal solar energy in the evening when demand is high and the sun has gone down, and some fixed cost to pay for physical electric grid infrastructure that needs maintenance regardless of whether it is being used at any particular moment.

Oil and gas don't buy polticians more than any other industry does, but voters do get particularly angry at politicians when the price they pay for energy suddenly spikes.


When you can influence the citizens of Rome for dimes on the dollar, why not steer the empire in the direction that benefits you?


I'm kinda tired of the argument where we only focus on some bad actors when it comes to online influencing.

Our countries absolutely do the same if not more to influence voters both here and in these other countries, especially online.


What could western nations possibly do to propagandise voters in Russia and Saudi Arabia?


The list of the oil producers listed and omitted on a given forum in these contexts is always interesting. On HN it is often SA or Russia, and almost never Qatar or Iran.


>Solar prices in the US are criminal, protecting oil and gas who bought all the politicians. >Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.

This very well may be true, but taken at face value Canada seems to be paying you around $7k to install solar panels on your roof (that's 8k interest free loan is losing out to inflation + any interest it would have earned).

Definitely a great deal if you own a home, if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.


> Definitely a great deal if you own a home, if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.

What kind of selfish point of view is this? Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year? Seems like a no brainer deal if you like "the outside" and you want it to still be there.

I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me. But I also feel the same about elder care, health care and a bunch of other things, do you feel the same for those things too, or this is specifically about solar or owning vs renting?


>I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me.

There's an alternative, and almost certainly cheaper per watt with cost of scale, where your tax dollars go to a new solar farm instead, something everyone could take advantage of.


Everyone can take advantage of rooftop solar. The power goes into the grid. This isn’t a zero sum game. We need both.


It's not zero sum but different physical layouts of energy generation do have different captial and operating costs. Rooftop solar power goes into the grid but maybe not at the most ideal time and scale for the grid operators, which justifiably affects what price they're willing to pay for that power, which justifiably affects the ROI for homeowners with rooftop solar panels.


Rooftop solar has lower distribution costs. A solar farm needs new transmission and upgraded capacity distribution lines to get the power from far away to the users. Generating solar right next to your neighbors lets them access your surplus cheap power with existing slack capacity in the distribution lines. Our current monopoly utilities don’t have a mechanism to recognize that value created, and they would prefer to keep building more infrastructure as that’s what increases profits for them.


Why not both? One works better for people not living in cities, and the other one better for high-density areas.


Because you get far higher ROI for the large-scale installations. In case you weren't familiar, Canada has a lot of other things which need the money than paying 5x per watt to subsidize panels on your roof instead of on the ground.


> Because you get far higher ROI for the large-scale installations.

Right, but as always, ROI is hardly the most important thing in life, there is more considerations than just "makes more money". For example, as someone affected by a day long country-wide electricity outage where essentially the entire country was without electricity and internet for ~14 hours or something, decentralizing energy across the country seems much more important, than optimizing for the highest ROI.

But again, this is highly contextual and depends, I'm not as sure as you that there are absolute answers to these things.


Grid-tied solar is fragile. If the grid is not nearly-perfect, it won't generate. It will not help society as a whole.

If you personally have battery backup, that helps you personally and you should pay for it, just like you might pay extra to turn up the heat while I keep it lower to save money.


In Canada (or the US) the grid is reliable and so you can ignore when it isn't working. This doesn't apply everywhere in the world


Which is why the money should go toward getting 10x utility solar than roof solar.


Grid-scale solar installations can be much more decentralized than nuclear or natural gas power plants.

Decentralizing through subsidies at the homeowner level is maybe not the best use of money.


> Decentralizing through subsidies

Consider the lower production cost of renewable electricity: in the long run, it offsets the investment. Bonus: no risk of accidents, no hazardous waste, no dependence on a fuel source, no weapons proliferation...


I didn't say subsidize nuclear. I said subsidize grid-scale solar before rooftop solar.


Indeed, sorry.

Decentralizing solar power reduces electricity transmission costs and improves reliability. This doesn't offset the additional cost, but it's not negligible.


If the grid gets heavily overloaded, the frequency and voltage drop. And home-based grid-tie solar will shut itself off when it's most needed. This is fragile and DEcreases reliability.


Storage, such as batteries coupled with V2G and also green-hydrogen fed turbo-alternators, can alleviate this.


>One works better for people not living in cities

It's not as if homes outside of cities have their own diesel generators to power their house.

(Since I'm guessing from this line of comments you'll point out the less than 1% of people who actually do do this, maybe it's better to focus only the 99% here).


> It's not as if homes outside of cities have their own diesel generators to power their house.

Yeah, no true, I don't understand the point/argument though?

More people relying on renewables == long term better for everyone on the planet

That includes moving people outside of cities to renewables energy sources, is your point that this isn't so important because they're a small piece of the population usually?


What's the difference between a new solar farm and new solar panels on roofs (or the ground) ?


The solar farm produces more energy per dollar spent. Rooftop solar is expensive. It produces comparatively fewer kw to amortize the fixed costs over - permitting, getting up on the roof etc.

If a country has abundant land and expensive labor, the money is probably best spent improving grid transmission capacity and otherwise getting the f- out of the way of utility-scale renewables. Places like Pakistan, which is going through a rooftop solar boom, are arguably the opposite - scarce land in the cities, but cheap labor to get up on roofs.

Happy to hear any analyses to the contrary and update my knowledge accordingly.


OK, so rooftop solar is a higher <currency-unit>/kW solar farm. That's one argument against it.

On the other hand, it is also distributed which from some perspectives is a benefit, and is also do-able with very little planning and grid extension. So that's one argument for it.

How things come out on balance depends a bit on what you value and how you imagine the future.


The generation is distributed. That only benefits the people who have panels on their rooftops. If we want them to share the excess with others during a power outage it requires further grid investment.

I think homeowners should install solar panels and batteries where it makes economic sense. If there's money left over after funding utility-scale solar then it should be used for EV incentives and/or funding electrified mass transit. The whole point is to electrify everything rapidly and reduce carbon emissions.


You absolutely do not want them sharing the excess with neighbors during a power outage, this is how you get dead linemen.

Solar panel grid tied inverters generally will refuse to function if there's no external power coming in.

The benefit from the distributed generation means that if your local area has large loads added you don't necessarily need to upgrade the HVDC lines from the power plant to accommodate.


This is not as big a problem as it sounds - you cannot provides enough power for you neighbors and so your breakers (fuses) will cut power long before the lineman gets there.

though linemen are trained that they are working on a live line unless they have personally shorted it out. There are many other ways a seemingly dead line can be live so they don't take a chance.


> This is not as big a problem as it sounds - you cannot provides enough power for you neighbors and so your breakers (fuses) will cut power long before the lineman gets there.

The load side (your neighbors) cannot pull more power than is being generated. My 7kW array can generate 7kW and no more. No breakers will trip in a hypothetical scenario where my inverter fails to shut down during an outage, and my neighbors are trying to drawing 10kW.


That's not how that works. Your breakers are sized to support your panel size. If you have 10kW panels that can push 10kW onto the grid when the grid is live, they can push 10kW when the grid is down. The limiting factor is the power your panels produce which in this case is also...10kW.

You're probably right about linemen but there are a lot of other reasons not to feed power onto a dead grid.


Your main breaker isn't the only one. Your inverters have protection of some sort as well.


Yes, all of which is by definition specced high enough to handle the maximum amount of power your panels are able to produce.


Upvoted.


Solar farms don't work during power outages either. When the power isn't out, you get to use the power from your neighbor's solar panel.


> What kind of selfish point of view is this? Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year?

Only if those who make the same or more than me are paying that same tax. After their subsidies of course.

Rich folks getting even richer off the backs of poor folks is bad. Even if it's dressed up as good for the environment or whatever justification you want to come up with.

As a homeowner, I would not take these subsidies as I find them to be immoral. Doesn't mean I won't be installing solar, but I'm doing it for far different reasons than saving money.

By your logic, shouldn't homeowners stop being selfish and just pay for these things themselves in order to make the world a better place? Why do they need renters, other taxpayers, and other ratepayers to subsidize them?


As a renter, I'm moderately more in favor of utility-scale solar subsidies rather than subsidizing private solar. It seems like another way to make the arrangement more "fair" is to subsidize private solar, but credit the grid up to the original grant's amount. In other words, in the GP's case, they would only get $1000/year in free money for 15 years instead of 20.

(This is very low on my list of things that I care about, to be clear.)


>I'm a renter, been all my life, I'd be happy to pay more in taxes if it means more solar panels for everyone except me.

That's because you're rich like most people on HN.

Environmental protection is a luxury good. This has been proven time and time again.

A great reason to prioritize growth and wealth creation. Poor countries don't make those tradeoffs, they're worried about survival not what percentage of their energy usage is renewable.


Solar hardware is so affordable now that it's booming even in poorer countries. The most remarkable recent example is Pakistan, which has seen explosive growth of rooftop solar power, most of it receiving no government subsidies:

Pakistan has imported almost 45 gigawatts worth of solar panels over the last five or six years, which is equal to the total capacity of its electricity grid. Almost 34 gigawatts have come in only in the last couple of years.

It’s a very bottom-up revolution. This is not government deciding this is the route to take. And it’s not being driven by climate concerns, it’s all about the economics. Renewables are out-competing the traditional sources of energy.

https://e360.yale.edu/features/pakistan-solar-boom


Right, so that implies there's no need for homeowner subsidies in wealthy, developed countries.


What's needed are Pigouvian CO2 taxes, but those aren't politically feasible.


Not really, unless you are just guessing. A quick read shows that solar gained popularity because of an unreliable grid and a removal of subsidies on diesel. Solar ended up being the cheaper and more reliable option. Labor costs for installation are also lower. In remote areas you may not even have a grid option. Simple general assumptions don't hold across vastly different geopolitical circumstances.


Right, so there's still no need for subsidies.


Yes it's awesome to see solar adoption without subsidies. Wonderful technology. Decentralized energy production is powerful.


> Solar hardware is so affordable now that it's booming even in poorer countries.

Even in Gaza Strip you'll see sometimes solar panels next to the refugee camps, and broken ones on top of the ruins.


Great job of indirectly implying that there must be a tradeoff. Funny thing though: those poor countries? They're not building nuclear, or oil fired, or coal fired, or natural gas plants. They're installing solar. Not necessarily because they care about what percentage of their energy usage is renewable, but because there is no tradeoff.

Further, environmental protection is not a luxury good, it's a long term investment. Ask me more in another 30-50 years when the larger impacts of climate change are happening. Or ask someone else about how much we've spent on superfund cleanup sites.


Everything has a tradeoff. That's a foundational truth of economics.

Environmental protection is a luxury good in economic terms. The Environmental Kuznets Curve is compelling to me. It's extremely difficult to assess the ROI on long term investments, particularly when your country has unstable rule of law or conflict.

I'm pro-solar, it's amazing technology that empowers individuals and communities. I just don't agree that everything I love I must force other people to pay for.


How do you compensate your neighbors for the loss of garden view caused by your house?


Is that something you usually have to pay your neighbors where you live? If you put up some ugly thing in your garden you have to pay your neighbors?


Sam said he doesn't force other people to pay for things he loves, so I'm wondering how he doesn't force his neighbors to pay for his house with their view.


Environmental protection may be a long-term investment, but reducing CO2 emission is probably not. The results are too diffuse and you're at the mercy of other countries' energy policy. If you're a small country, you can invest in CO2 reduction all you want, but what actually happens will be up to the US, China, and India.


> That's because you're rich like most people on HN.

Probably, but I also haven't been rich all my life, I've also been broke and borderline homeless, and my point of view of paying taxes so others get helped, hasn't changed since then. In fact, probably the reason my perspective is what it is, is because money like that has helped me when I was poor, and I'd like to ensure we continue doing that for others.

And I agree, poor countries can't afford to think about "luxury problems" like the pollution in the world, but since we're talking about people living in such countries where we can afford about these problems, lets do that, so the ones who can't, don't have to. Eventually they'll catch up, and maybe at that point we can make it really easy for them to transition to something else?


Environmental protection IS about survival for poor countries. YOU can afford to not care and burn gas because you won't have your life completely and permanently destroyed by global warming. Poor people don't have that luxury.

Rethink your position because it's completely upside down


the only reason environmental protection could conceivably be considered a luxury (and not a necessity) is because certain sectors of the capital class refuse to convert their means of production away from generating waste and pollution. that's it. time and time again we see direct action by Chevron, BP, Shell, Exxon, ARAMCO et al to stifle change, refuse scientific evidence of the nature of their pollution, and attack anyone who comes anywhere near impacting their bottom line. look at Steven Donzinger if you need proof of this.

this is not a matter of some fictional invisible hand. these are decisions made by real people who do not care about you, society, the health of the environment or the people who inhabit it. stop carrying their water.


> Environmental protection is a luxury good. This has been proven time and time again.

I see this lie repeated in many places. Environmental protection is much, much cheaper than the alternative.


> A great reason to prioritize growth and wealth creation. Poor countries don't make those tradeoffs, they're worried about survival not what percentage of their energy usage is renewable.

Tell that to places like Pakistan where solar is allowing people to have cheaper electricity without connecting to the grid


That's exactly my point. They're making decisions based on their economic reality not sacrificing for environmental principles like the above commenter.

Solar is great. It can stand on its own without subsidies.


Keep in mind the standard of living. If you’re in a country that experiences routine long power outages, having a solar panel that you can use to charge your phone during the day is pretty great. Having to get ahold of and burn diesel fuel is not so great. Doesn’t produce at night? Doesn’t matter much, it’s better than nothing.


There is line that connects gov't subsidies in wealthy countries for the last 50 years funding private R&D to poorer countries being able to afford it. Arguably the poorer countries don't get to make the "decisions based on economic reality" in favor of solar without the subsidies in wealthy countries happening first. There is also an argument to be made that the R&D isn't finished and it still makes sense to subsidize it to drive the cost down further.


> There is also an argument to be made that the R&D isn't finished and it still makes sense to subsidize it to drive the cost down further.

Maybe there is an argument to be made, but it sounds like a very poor one if poor countries are now putting up solar panels because it's the cheapest form of energy production. Sounds like subsidizing the same panels going up on houses is a bit silly now that the costs have shifted so much.

The argument can probably be made for direct subsidies of R&D for bleeding edge solar tech, and perhaps even battery installations to get volume up. Or maybe even subsidizing local production vs. buying everything from China.

The arguments for wealthy countries to subsidize their wealthiest citizens to install solar for personal gain seems rather weak at this point in the game. It certainly made sense 20 years ago, but in most areas where it makes economic sense to begin with solar penetration has hit a tipping point.


> They're making decisions based on their economic reality not sacrificing for environmental principles

You don't know this, and to some degree likely cannot know this.


At an individual level? Agreed.

But at a national level the data is compelling. I'm convinced by the Environmental Kuznets Curve.


> But at a national level the data is compelling. I'm convinced by the Environmental Kuznets Curve.

Which data do you find compelling?

For people who don't know the Environmental Kuznets Curve is basically the hypothesis that as economies grow past a certain they naturally start to cause less environmental damage.

As far as I can tell the main empirical evidence in favour of this is the fact that some western countries have managed to maintain economic growth whilst making reductions to their carbon emissions. This has, of course, partially been driven by offshoring especially polluting industries, but also as a result of technological developments like renewable energy, and BEVs.

On the other hand, taking a global sample it's still rather clear that there's a strong correlation between wealth and carbon emissions, both at the individual scale and at the level of countries.

It's also clear that a lot of the gains that have been made in, say, Europe have been low-hanging fruit that won't be easy to repeat. For example migrating off coal power has a huge impact, but going from there to a fully clean grid is a larger challenge.

We also know that there are a bunch of behaviours that come with wealth which have a disproportionately negative effect on the environment. For example, rich people (globally) consume more meat, and take more flights. Those are both problems without clear solutions.

(FWIW I agree that solar power is somewhat regressive, but just for the normal "Vimes Boots Theory" reasons that anyone who is able to install solar will save money in the medium term. That requires the capital for the equipment — which is rapidly getting cheaper — but also the ability to own land or a house to install the equipment on. The latter favours the already well off. There are similar problems with electric cars having higher upfront costs but lower running costs. The correct solution is not to discourage people from using things, but to take the cost of being poor into account in other areas of public policy).



Yes, and it's wonderful to see. As the article itself explains, this isn't due to government led redistribution of wealth anymore:

> The 20th century infrastructure model was:

> Centralized generation

> Government-led

> Megaproject financing

> 30-year timelines

>Monopolistic utilities

> The 21st century infrastructure model is:

> Distributed/modular

> Private sector-led

> PAYG financing

> Deploy in days/weeks

> Competitive markets


Turkey is a poorer country and has more wind and solar capacity by percentage than US.


Canada isn't poor.


Agreed. But there are poor people in Canada, and forcing them to pay more money (and slightly lowering their own quality of life) so that wealthier Canadians can install solar panels is, at least, a debatable policy.


We have progressive tax rates in Canada which should offset this to some extent.

Also, you keep ignoring that the environment is a public good. Poor people in Canada will also be disproportionately impacted by bigger temperature extremes (heat waves, extreme cold), worse air quality, etc.)


Does Canada not have progressive taxation? How do poor people pay more than rich people?

To be clear, I don't think rooftop solar subsidies are the best use of government money either. Governments should subsidize utility-scale solar, EVs, efficient buildings, and mass transit. They should focus on cheaper and more efficient permitting, and better grids.


> Does Canada not have progressive taxation? How do poor people pay more than rich people?

It’s not that they’re paying more than rich people. It’s that even with progressive taxation, tax(everything the government currently spends money on) < tax(current spending + solar subsidies). That is to say… giving solar subsidies to rich people causes the tax paid by everyone to increase. Those making more money pay a larger fraction of the increase because of progressive taxation but everyone who is paying taxes pays incrementally more when the government spends more money.


Canada should invest in Nuclear. Solar is far less efficient in Canada than somewhere like California - whether rooftop or utility-scale. The short winter days, low angle of incidence, and snow means that panels are basically non-operative for 3-4 months a year. This is a huge problem if you also want people to switch to efficient electric-powered heating in the form of heat pumps.


Great, if the break ground today the first nuke will be online in absolute minimum 10 years (likely 20) and cost absolute minimum of $15 billion (likely closer to $30 billion)

Do you want to guess how cheap solar will be in 10-20 years, and how much power we could generate in the mean time.

This is not a discussion worth having.


Canada already has lots of nuclear: https://ember-energy.org/data/electricity-data-explorer/?ent...

The efficiency of solar does not matter in 2026. Panels are so cheap that just you don't have to think about it if you have abundant land. If solar is 4x less productive in the winter you just build 4x as many panels. Panels have to be angled more vertical the further north you go so the snow will just slide off. They are not "non-operative 3-4 months a year" - this is just Big Oil FUD.


Everything has tradeoffs - those panels themselves take energy and rare earth minerals to create, and getting both of those requires pollution, primarily in China where they have lower standards than western nations.

So filling Canada with panels because they're cheap isn't likely the best environmental choice, on net. Though I admit I haven't done the math here, it's just an intuition that "just build 4x panels" isn't the solution.


Your intuition is flat out wrong. Building new nuclear takes too long. "Just fix the nuclear regulations" is a vibes-based statement. Even China built 100x as much solar as nuclear in 2025. Wouldn't they "lower standards" to build more nuclear if it made any economic sense?

As for

> those panels themselves take energy and rare earth minerals to create

You've swallowed Big Oil propaganda and are choosing to parrot it without thinking. The actual truth?

"Every year, [ICE vehicles] consume over 17 times more tons of oil (2,150 million tons per year) than the amount of battery minerals we’d need to extract just once to run transportation forever. Even when including the weight of other raw materials in ore and brine, one-off mineral demand would still end up over 30% lighter than annual oil extraction for road transport. And unlike minerals, oil products are promptly burned in internal combustion engines and must be replaced each year, forever

Admittedly this is about minerals for batteries. But solar panels are also recyclable.

The reason Nuclear takes so long is that people are neurotic about it and so the regulations are totally excessive. If we had a standardised reactor, it wouldn't be that difficult to churn them out.


The nuclear industry rightly fears excessive standardization because the more units of a given reactor model are built, the more drastically production is reduced by the discovery of a serious bug that leads to their immediate shutdown.

This is one of the major design problems of SMRs (along with the abandonment of economies of scale).


Since you clearly didn't read past the second sentence in my post I'm going to repeat myself. Why doesn't China repeal "excessive" and "neurotic" regulations and build more nuclear instead of solar? Rather than the other way around?


because they sell the solar panels abroad and can't sell nuclear power plants abroad.


That's why they're installing 100x as much solar as nuclear domestically too?

Why can't they sell nuclear plants abroad? Sure Western countries won't buy them but the rest of the world probably would if the price were right.


Rich people are usually early adopters of new technology. That's how technology gets cheaper. It's fortunate and unfortunate at the same time.


Maybe I'd prefer to spend the same public money on building nuclear power plants, or gigantic solar panel arrays in the desert, rather than subsidizing individual roof-owners being able to save money on their electricity bill and not mine.


>Don't you want people to use energy sources that are better for our entire world, even if it costs you like $10 more in taxes per year?

If everyone gets the benefit it's either A) exactly the same cost but with additional government program or B) some form of wealth distribution and not necessarily in a direction you favor

Also large solar installations are significantly more cost efficient.

Mind you I am IN FAVOR of subsidized residential solar, but let's not pretend government money is free.


In Japan, where we're currently getting rooftop solar (like nearly every single house everywhere) there are indeed some large solar installations, but the point of rooftop solar (which the government is encouraging) is that it reduces the pressure on the grid itself, and upgrading the grid in Japan to where it should ideally be is a huge, no, astronomical undertaking. For various reasons.


Also, more people having solar have the indirect effect to bringing energy prices down for everyone.


> I'd be happy to pay more in taxes

Giving money to politicians is like giving whiskey and car keys to teenage boys.


Not sure how it is where you live, but when I pay taxes they don't go to politicians. The taxes go to health care facilities, infrastructure, education, etc. etc. Only a small percentage goes to pay politicians, and it's all in the open - we know exactly how much each of them is getting.


And are those programs where capable of delivery anything on time and on budget?


Some are, some are not, and some are before time and below budget. In other words, it varies.


There is nothing more unjust than forcing someone to buy something they do not want simply because you think it would be good for them.

> Seems like a no brainer deal

This is opinion, not fact. I happen to share your opinion, but enshrining opinions in law is almost always going to violate someone’s consent.


> This is opinion, not fact

Not OP, but it wasn't presented as a fact. Literally used the word Seams.

> There is nothing more unjust than forcing someone to buy something they do not want simply because you think it would be good for them

Seatbelts? Circuit breakers? Literally any safety equipment. You're required to have them because it's not just good for you, but expensive to society if hospital beds are low or there's not enough firetrucks to go around.

Similarly, if you're polluting more than you have to be due to the source of your electricity, that's bad for everyone. I also rent, but I still understand that it's to the public's benefit that home owners (a class that is already above me in assets and wealth) be given motivation to consume cleaner energy if I don't want to have the climate get even worse. It's the same thing, just the effects feel less direct. That doesn't make them any less valid.


> There is nothing more unjust than forcing someone to buy something they do not want simply because you think it would be good for them.

Who said that? Taxes are what you pay to be a member of the society you live, and also to help those less fortunate, like your neighbors. You can skip paying those, if you stop living in society, many done that before, and it is still possible.You can't possibly see taxes as "forcing someone to buy something they do not want" right? Two completely different things.

And yes, this is all my opinion, like most comments on HN.


> You can skip paying those, if you stop living in society, many done that before, and it is still possible.

Actually, generally speaking this is almost certainly not possible for more than short periods of time.


It certainly is possible, people do it all the time, in various countries. Most of the time we call them "homeless", but also there are people who literally set up camp in the forest then stay there, it isn't unheard of.

The book "The Stranger in the Woods" is one such case, about a man who lived in the woods for 27 years by himself.

That said, it isn't easy, and it's harder in some countries than others, but I'd still say it's possible in many countries today, YMMV.


Nothing like the exception for proving the rule ...


And they still benefit from taxes.


I feel like it's worse to force someone to buy something they do not want, knowing full well it's going to materially harm them


We are in agreement.


This is a failure of imagination. There are plenty of things that are more unjust than that.


> if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.

You probably wouldn’t. I hear more people complaining about hypothetical government spending than actual government spending.


In Germany you are allowed to install solar to your balcony as a renter.


> if I was a renter/condo owner I'd be annoyed that everyone is subsidizing your free solar however.

As a non car owner are you annoyed everyone gets subsidized roads?

Are you annoyed corn farmers get subsidies for growing corn?

Would you be annoyed if people got subsidized life saving health care?

It feels like the US can’t have nice things because people are hell bent on others not having nice things.

What a shame.


> As a non car owner are you annoyed everyone gets subsidized roads?

Yes, and people should be annoyed by this given the underfunding, poor urban planning, and outright hostility by many local governments against anything that dares encroach on the sanctity of car culture.


"Car culture" and "public roads" are not the same thing.

I'm a militant cyclist and I'm extremely unhappy with the state of urban planning in the world. But... Roads are a really good thing and I'm glad my government builds them.

I just wish they'd built them a bit differently, at least in the city.


I am not trying to equate the two concepts. Just that in most of North America car culture is what dictate the roads we have and who they’re built for.


>Yes, and people should be annoyed by this

So you do not use busses,taxi or road travel? do you fly all the time? Do you have stuff delivered by truck/cars or only by air? What about shopping? do you think the items you buy or the things needed to make those items use roads ? In a perfect extremist capitalist word there would be a road tax included in the products and services so you would still pay the text for the roads.


No, in a perfect world, there would be a use tax, and those doing the delivery would pay the cost, and then pass that cost on to you. You might have meant it that way, but it sounded more like a gov. imposed tax based on the price of goods or something.


Trucks are responsible for 99% of road damage and only pay 38% of the costs.

https://truecostblog.com/2009/06/02/the-hidden-trucking-indu...

Yes, the costs should be apportioned to those who are making them. If the bus causes the most road damage, then it should be charged. Then it'll make financial sense to invest in rail. Financial incentives are how capitalism works and the purpose of governments under capitalism is to apply externalities to the source causing them.


It'd be interesting to try charging vehicles relative to the road damage they do as it's proportional to around the fourth power of weight. It would likely change the nature of logistics as it could mean that large trucks would be more expensive that using two or three smaller trucks. Similarly, buses would benefit from being smaller and lighter.


Trucks already have lots of axles and wheels for this reason, because it's weight per wheel that matters.


I suspect the number of axles and wheels is to generally improve the strength/weight ratio rather than to minimise road surface damage.


Nope, the requirement comes from government standards intended to reduce road damage and specifies maximum ground pressure.


Okay, so there is a maximum. Charging proportionate to the road damage costs would still change the cost benefits of using single large vehicles vs multiple smaller vehicles, or possibly lots more axles.


Should cyclists be charged a special tax for bike lane construction and maintenance? What about sidewalks, should you need a pedestrian pass?


1. As soon as the roads are all paying best-possible-use property tax for the space they take up and it's completely paid by automobiles, in addition to all maintenance, we should try to proportionally assign dedicated bicycle infrastructure costs toward bicycle users, now and anticipated.

2. Everyone is a pedestrian.


People accuse communists of being unrealistic idealists, but they have nothing on the libertarians.


That's the first I've heard of a https://en.wikipedia.org/wiki/Land_value_tax (and, less directly, https://en.wikipedia.org/wiki/Georgism ) being libertarian!

fuck cars


User pay formerly-public-infrastructure is what I identified as libertarian. Would you also advocate for residents of high crime areas to pay more taxes for police coverage?


"User pay" is typically associated with regressive per-use taxes. It's perfectly compatible with socialism to ensure the cost of the road system is applied to only automobile users in a progressive manner. Relatedly, Finland moving violation fines are not a fixed fee and are proportional to income: https://nri.today/wealthy-speedsters-beware-finlands-million... Stop thinking "cars=default", they are not.

Legally criminal actions are violations against the state, which is why a prosecutor decides whether to file charges and does not need the consent of the victim to do so. We already have what you suggest with civil law and private security.


It's pure pedantry to distinguish between "user pay" and "progressive fees" based on usage. You're advocating for private payments on public infrastructure, it doesn't make it socialism just because it's infrastructure you disapprove of.


> So you do not use busses,taxi or road travel? do you fly all the time? Do you have stuff delivered by truck/cars or only by air? What about shopping? do you think the items you buy or the things needed to make those items use roads ?

"Yet you participate in society, curious!"

> In a perfect extremist capitalist word there would be a road tax included

There's nothing capitalist about that. Driving around and polluting the environment is currently done for free. That should be taxed. Highways and streets are by and large (in NA) used as a publicly subsidized private good at the expense of everyone else. Subsidized to the detriment of all because it pulls funding away from public transit that would move more people, prioritizing convenience of drivers over the safety of everyone else (to say nothing of it creating dead spaces with nothing but parking as far as the eye can see).


Public transport uses the roads too. In my country Romania there are road taxes included in the fuel prices and there are vehicle tax that is proportionalw itht eh engine size and vehicle age and how mych it pollutes. So people that drive more use more fuel and pay more tax. If you use your bike then you will not pay that taxes, now what should we tax for the bike lanes ? And how should we convert he fuel road tax for electric cars ?


> tax for the bike lanes

That already exists. In large parts of North America there isn’t a tax proportional to vehicle age, and the tax on gasoline doesn’t cover road wear (to say nothing about the unproved externality of pollution). So municipal property taxes and the like are used to cover the costs of road repair.

> electric cars.

The same way we pay for electricity and natural gas, report your kms and then have the odometer inspected on a semi regular basis and when you get rid of the car.


Why are you acting like subsidizing a homeowners free power is like any of these?

If I instead phrase it as "I'd rather subsidize someone's health care than pay for your free electricity", would that help you understand that there tends to be a priority system when spending tax dollars?

You don't have infinite tax dollars to spend after all.


> Are you annoyed corn farmers get subsidies for growing corn?

Yes we should immediately end these subsidies.

> It feels like the US can’t have nice things because people are hell bent on others not having nice things.

The US as a whole has lots of nice things. And sometimes the things the US has are not as nice as they could be because an unwise subsidy is paying for something inferior, and a small group of people who financially benefit from the subsidy advocate politically against changing it.


Yes, yes, and yes. Is it an intentional mischaracterization to conflate not wanting wealth redistribution with “others not having nice things”?

“others not having nice things” is a superset of “others not having unearned nice things”.


I don’t see where roads are unearned?


If you're a renter/condo then you're probably getting excess solar generation delivered to you from homeowners with nearby solar roofs. So presumably there is some benefit to you in terms of cheap generation.


Also... Fewer houses using fossil-fueled power on Earth. If you live on Earth that's pretty good.

The answer to this isn't "less subsidies" it's "find a way to make everyone benefit from the subsidies.


Your last argument could apply to anything really.

Why should I subsidize farmers if they can't compete?

Why do I have subsidize our own manufacturing companies if they can't compete so their workers have a job, at my expense?

Why do I need to subsidize car owners to have yet another lane but can't get a decent train instead?

Here in Poland suddenly all miners pretend to be subsidized by the state, even if they work for private companies.

Why do I need to subsidize them if the companies they work for can't turn a profit, or when they did for decades chose to pay dividends and do buybacks instead of investing? And now I pay the bill?

I mean, at some point you need to cope with the fact that money has to be spent and circulate in some fashion to promote economic activity and projects.

You could argue that subsidizing solar brings energy prices down in any case.


Yeah, truly awful. Unlimited electricity that barely contaminates, and at the lowest possible cost for everyone. Just terrible.


Be less annoyed because utility demand declines.


Canada is blessed with cheap energy, the abundance of hydro surely helps to bridge any intermittency other renewables have. I lived there 10 years back, your energy is less than half the cost of mine in Scotland. In Scotland's case we're part of the UK and the rest of the UK is less blessed with the geography for hydro. The incumbent Scottish government also has an anti stance to nuclear.

I hope the incentives for cleaner energy continue to stack up. With the surge in demand from AI surely productivity will be more tightly coupled with energy usage and cost.


There is enough wind potential in Europe to power the world [1]. Combined with interconnects to Europe and battery storage, there is no reason power costs can't be driven down. To not do so is a lack of will. Scotland currently generates a surplus of renewables [2], exported. kieranmaine's sibling comment citations dives into the lack of will part.

[1] https://news.ycombinator.com/item?id=38722022 (citations)

[2] In Scotland, Renewable Power Has Outstripped Demand - https://e360.yale.edu/digest/scotland-renewable-energy-100-p... - January 30th, 2024

(at the rate it takes to deploy transmission, might as well start dropping TBMs in the ground and let them grind towards each other from interconnect landings, potentially faster than the approval grind, complaints from locals about land use and right of ways, etc)


In Scotland one issue is that the UK electricity market is national (unlike in eg norway). So even if local supply is very high and interconnects are not large enough to export to england - we must pay the higher national rate. As octopus ceo suggested if the UK energy market has regional pricing then electricity in scotland would often be a lot cheaper and in some cases industrial demand would move there. But that would disadvantage the SE of England so will never happen.

Conversely, standing charges ARE regionalised - because that does advantage the SE of England. Oh well!


Related to UK energy I read this interesting article on transmission congestion between Scotland and England and how this is increasing energy costs due to curtailment of renewables.

https://ukerc.ac.uk/news/transmission-network-unavailability...

TL;DR - Until new interconnectors between Scotland and England are finished in 2029, there will be significant curtailment of Scottish wind power which increases costs.

This is also an interesting site for seeing curtailment per wind farm - https://windtable.co.uk/data?farm=Seagreen


The UK will perpetually have "issues" that lead to higher pricing. We just put up and pay. It is unspoken energy policy to be expensive

Oh no we messed up nuclear oops sorry made it very expensive. Pay up

Oops sorry we messed up transmission pay up

Oops sorry we let people get into huge energy debt pls pay off their debt in your bill...


It has been a long standing problem.

Ideas crop up like generating hydrogen with the curtailed energy or maybe at least in Winter, use it for heat generation. The problem would seem to be the capex and the inverse of intermittency being the problem for them in utilising that energy, i.e. waiting for curtailment.

At least with available hydro you can pump water back up hill using a reliable and cheap tech.


I find it fascinating that we have not identified a use for almost free intermittent electricity. You'd think there would be plenty of things to do, but it seems like with the capex investment things like smelting etc need to always be running. Maybe electric car charging can come to the rescue? But even there people need their cars charged usually at certain fixed moments.


EV smart charging is a solved problem in the UK IMO, at least for those with a parking space.

OVO[1] and Octopus[2] offer smart charging tariffs that give EV owners reduced electricity rates.

The usual caveat is you can only benefit if you can install a charger and park near that charger. Still, based on this 2021 article [3] 65% of UK homes have at least one off street space, so the potential for a majority of homes to smart charge is there.

To extend the benefit of cheap smart charging to more people, it would be good to see legislation that makes it easier for leaseholders and renters to require the installation of a smart charger where technically possible.

1. https://www.ovoenergy.com/electric-cars/charge-anytime 2. https://octopus.energy/ev-tariffs/ 3. https://www.racfoundation.org/media-centre/cars-parked-23-ho...


Agree. It seems to be a fairly unique problem that intermittent energy sources introduce.

Charging batteries definitely seems like part of the solution and electricity tariffs that adapt to wholesale costs on a shorter time basis help incentivise it. There are times over weekends/holidays where the wholesale price enters negative territory, essentially paying you to charge your battery.

Electrolysing hydrogen to burn is inefficient vs that kind of thing but at least acts as a battery itself, though there's costs/problems in storing it.

And the general problem of how long do you need to store energy vs what the weather forecast may be.

It seems like it's not a solved problem and it'd be exciting to move towards a point where it is. Hard to believe in the 50's they thought nuclear would solve everything and would be "too cheap to meter"


Everything that I learned about energy in Scotland comes from Still Game, so I must ask -- how many bars?


"One bar's plenty!"

Put the bulb on. That suggests warmth.


The Greener Homes Grant and Greener Homes Loan you describe have ended, but the 160% tarrif on imported solar panels remains. Solar prices in Canada are still quite expensive, and regulations are needlessly strict. Solar fencing is illegal in many jurisdictions, balcony solar is illegal everywhere, and utility-scale solar is effectively prohibited in the regions with the most sunlight.

Solar production in Canada will continue to grow, but we're not doing nearly as much as Europe to encourage it.


I’m wondering out loud if you might be able to purchase what would essentially be the component parts of a solar panel but deconstructed (eg frame, cells, glass, wires; maybe the cells need further deconstructing) and do final assembly in Canada such that the final panel meets criteria to be “built locally”, potentially built of local and imported parts.

Surely local manufacturers don’t use 100% Canadian made parts.


Some provincial grants remain ($5k in BC last time I checked), but yes - Canada can and should do more. Balcony solar seems like such an easy win. Hopefully tariffs get dropped now that we’re talking to China again. And federal Liberals could force municipalities and provinces to reduce some of the red tape surrounding solar installations. Come on Canada, unlocking clean energy shouldn’t have to be a fight!


And that on-roof-solar helps (as it becomes widespread) mitigate the growing need for additional grid capacity. Canada is a big country and, outside the major cities, upgrading grid capacity is quite expensive per capita. It's a win-win in Canada, investing in self-sufficiency while reducing the maintenance burden of infrastructure.


It may slightly help with capacity, but it causes bigger problems financially. Even if a home uses next to no power, it still must be connected to the grid. The total number of such homes ends up meaning a lot of power lines, transformer stations, monitoring equipment, and people to do all the work.

If you have all of that expense, and suddenly people have solar panels so pay $0 for an energy bill - do you see the problem? The actual cost of fuel/generation is very small compared to the fixed costs.

The more people use solar, the more in the red the utility becomes. You can 'fix' this by making it so every home has a fixed 'connection cost' and then a smaller 'usage cost' on top, but that destroys the incentive for solar panels - they'd never break even for the average buyer.

Solar is great, fantastic even. But it should be done centrally, or people will have to get used to the idea that they will never pay themselves off and are just doing it for the environment.


Where I from, every utility bill has two parts: fixed cost and metered cost. You pay for installed capacity and by the meter for actually consumed kWh, GJ, m3.


The term you're circling is "grid defection".

> must be connected to the grid.

That's a legislative problem. If a home can prove it can produce enough electricity for itself, it should not be forced to be connected.

> You can 'fix' this by making it so every home has a fixed 'connection cost' and then a smaller 'usage cost' on top

A lot of places already do this.


It's not a legal problem. The reality is that the vast majority of homes with solar must be connected to the grid because that's how they're wired and designed. You can do a completely off-grid approach, but it's more expensive and requires large batteries. Most people just do the simple panels and don't have any intention of going off-grid.

Also: Even if half of a neighborhood doesn't need the connection, the work ends up being similar. It's more based on distance/area.


Even if you stay connected, many place already charge you a fixed cost every month regardless of usage, which presumably should be covering this


That is an interesting theory, but it doesn’t work like that in reality.

Australia is giving free power to everyone during the day because they have so much.

More solar is a great thing.


If there is no in-house storage to match, how does it help the grid? It is still needed for cold winter nights, where demand is high and solar panels produce nothing. Hydro can provide the power, but the grid will be running at full load.


Most houses in Canada are heated with natural gas. I'm not negating your overall comment, but in general, cold nights don't strain the grid because of heating needs.


Latest Data Shows the Rapid Growth of Heat Pumps in Canada - https://www.theenergymix.com/latest-data-shows-the-rapid-gro... - November 5th, 2025

(still good news, as most of Canada's electric generation is low carbon hydro, and the rest of fossil generation can be pushed out with storage and renewables, although I do not have a link handy by province how much fossil generation needs to be pushed out)


Depends on your system constraints.

As an example:

I live in New England. We do not have enough natural gas pipeline capacity to meet demand in long periods of very cold weather, and have very limited natural gas storage that can't buffer that for as long as a cold spell can last.

In these periods of time the grid traditionally keeps the lights on by switching over a significant portion of the grid to burning oil for power, and/or with the occasional LNG tanker load into Everett MA. These are both....pretty terrible and expensive solutions.

Burning less natural gas during the day still helps at night/at peak, because it means there's been less draw-down of our limited storage/more refill of it during the day, so we don't have to turn to worse options as heavily at night.


cold winters aren't as bad for the grid as you might expect because the cold keeps the power lines cold which lets you pump more power through them.


in-house storage helps, but net-metering and grid-storage also works


I think the inverse has proven to be largely true. If a home that uses effectively net-zero power is still connected the grid, it becomes a liability to grid stablity and expense.

There still needs to be enough power to supply to all those homes in the event of a protracted time where solar is unavailable. It gets less applicable as homes start to get multi-day battery banks installed, but those are incredibly rare since they are too expensive.

The whole "wealthy homeowners get subsidized solar and then effectively free backup power paid for by everyone else" needs to end.


Solar does basically nothing to help with grid capacity.


If solar is cheaper than the alternatives, then installing solar means more money for growing the grid capacity as well.


450W-500W solar panels are as low as 52€ here in Germany if you buy a couple of them. Batteries are also very affordable and I look forward to them getting a lot cheaper soon, thanks to Sodium-Ion.


The price of panels is falling so fast I don’t think anyone truly understands.

I paid nearly double that for our 450w panels 18 months ago.


They are cheaper than fencing material, and will continue to decline in price.


And, credit where credit is due, it's all thanks to China.


The one country that still produces goods rather than switching to complete financialization!


Just to point out, but producing goods in exchange for pieced of paper is a weak system, especially if it's focus is export and not internal consumption, see Germany, Japan, Italy or China, all slowing down due to their reliance on exports.


To stay strong, you have to keep exercising your muscles or they will atrophy. To stay smart, you have to keep exercising your brain. To be able to produce stuff, you have to keep producing stuff no matter which country it goes to.

People keep saying that prices of panels keep falling, and yet any time I look at getting panels on my roof the price is the same $3/W it has been for 10 years already.


The prices are falling at the source, but free trade was never real; and it's even less so today. By the time these panels reach your roof, all kinds of fees and taxes have been tacked on. You'll be paying the maximal extractable amount.


Buying the panels yourself, or an install company supplying them?

What country?

In 10 years the price has fallen dramatically, you’re getting majorly ripped off.


The panel price doesn't matter. It's the installation and the surroundings (electrical setup, converter, battery) that determine the price nowadays.


Almost identical array in the states (7.8kw) — $25K out of pocket, down to about $12K after state and federal tax incentives.

Still made sense financially, pays for itself after ~8 years and the panels are warrantied for 30... but we're seriously lagging.

There's a similar phenomenon with heat pump systems. Installation costs are absolutely absurd.


> Dad in Victoria Australia just got 10.6kw fully installed and operational for $4000 AUD. ($2,700 USD)

How the heck are the panels even installed and connected for that price? That's about 25 panels, IIRC. What about the installation material and the ac/dc converter?


All covered in that price.

Government incentives. Spend tax dollars putting solar on literally every roof in the country instead of more coal or nuke plants.


Figure out what you can do without a permit or inspections in your jurisdiction.

For example, in my jurisdiction it's: < 5 square meters of panels on your roof, <60V DC, AC on homeowner side of panel (as long as electrical work done by homeowner).

That's not a lot, but my primary purpose is as a generator replacement -- keep my fridge powered during a summer power outage or my furnace fan powered during a winter one. The other 364 days of the year it just slowly pays for itself.

Panels, battery, wiring and paying a roofer to install the flashings for the mounts all cost under $3000. A single one of the required inspections would have cost about that much.


>Australia has so much electricity during the day they’re talking about making I free for everyone in the middle of the day.

Not just talking about it, if you get a smart meter and sign up for a plan that matches the grid rates you can actually be paid to take electricity during the day right now.

If you're wondering "couldn't you just make bank with a battery" yes you can. In fact Australia dominates the world in grid connected storage (per capita) and this chart itself is actually out of date (it's growing even faster than shown).

https://elements.visualcapitalist.com/top-20-countries-by-ba...

I'll also point out that gas and oil generation has declined rapidly.

https://reneweconomy.com.au/the-rise-of-battery-storage-and-...

For anyone that thinks renewables can't phase out peaker plants it happens very naturally and rapidly once there's enough solar to set rates negative in the day.


How is it that people haven't turned to bitcoin mining (or similarly large energy dumps) during the daytime?


The cost of the rig and the few inconsistent hours a day its negative i’d guess.

It’s not in the negative enough to be worthwhile dumping max amps but it’s certainly worth storing to buffer against peak hour pricing.


Another impact on solar adoption in the United States is that many home insurance companies are refusing to pay on claims against roof damage from poor installs. And there are a lot of poor installs, which has led to this problem. So now the homeowners are taking all of the risk on a solar install that already has an 8-10 year ROI.


“Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.”

I think a big part of why the US GDP is so high is that a lot of things are just f…ing expensive. Education, health care, solar, restaurants and so on. You have to actively resist the “usual” lifestyle or you end up in a sea of debt.


And that's $1000 per year at today's energy prices, which surely will go up over time.


One could hope with improving tech and decreasing regulations we could have decreasing (nominal) energy prices in the future. That would be progress.


We'll most likely see off-peak or dispatchable-demand energy prices become effectively negligible due to cheap intermittent sources, but the price for reliable 24/7 supply will if anything trend higher. Storage is not enough to bridge the gap in all cases, so you need either very expensive peaker plants or less expensive nuclear to provide a reliable baseload supply for those critical uses.


The baseload framing is increasingly outdated. What grids need isn't constant supply - it's flexible supply that matches variable demand. Solar + batteries handle daytime and evening peaks well. Wind fills different gaps. The remaining "firmness" problem (extended low-wind, low-sun periods) is real but smaller than baseload thinking suggests. Most studies show you can get to 80-90% renewables before you hit hard storage limits. The last 10-20% is the expensive part, but that's a different problem than needing baseload for everything.


And HVDC long haul offsets a lot of those problems as well and is more effective than storage.


Yes if we could only build them. I recently learned there was one built from the Columbia river hydro projects to southern California in the early 1970's Has one been built since?


Demand is rising very fast compared to supply, I don't think that will happen.

Energy is like RAM or clockspeed: you can't have enough of it.


> decreasing (nominal) energy prices in the future

Hasn't happened ever before, not sure why this time it would be different.


Happened constantly till around 1970. One horse power used to take a horse. Now a very small electric motor for cents per day.


They’re already locked in approved to go up at least 6% a year here. It just went up 16% this year for people out of town.


What? No Canada isn't cheap solar power -- last I checked rooftop ballasted solar is a 12-14 year payback on avoided costs. Inverter will go beforehand and that excludes any op costs. 8k$ free loan doesn't really provide as much value as you would think.

FWIW - I am all for solar but selling rooftop solar in canada as cheap and no-brainer is false.

3-4 year payback would be a no brainer. 8-13 year payback with an inverter upgrade and op-costs is definitely a decision that needs to be thought out.

The grid you are offsetting is fairly green to begin with so the net benefit is marginal.

If you are going to be isolated and put backup power into the equation. You ROI tanks further but at least you have about a day or two worth of energy in the storage asset.


Anything under $2.25/watt would put it within under a 4 year payback period, Alberta has good rates for solar. Rooftop solar doesn't have operating costs that I can think of unless you want to clean them and clear snow which is optional. And inverters usually have a 20-25 year warranty.


Inverters are 5-10 year warranty.


Largely agree, with one big nitpick.

Canada is a massive exporter of electricity to the USA. The more clean energy CND produces the more there is to displace North East's coal.

Of course, solar on Canadians' roof is a joke. A proper regulatory regime would encourage solar in Arizona and encourage lettuce Canada; not vice versa.


I don't disagree but the major energy being exported is from hydro or nuclear. It isn't coming off rooftop even at the margins. Rooftop solar is purely residential play.

If you are trying to argue that in aggregate the demand for energy in canada drops because of high adoption of residential solar which then passes off clean energy to the US - its a reach. Also the amount of individual infra for each small residential asset is probably not particularly great return on investment - would be better to do as large deployments.


Don't get me wrong, I think solar in Canada is stupid. Given a limited supply of panels, they should be installed in Arizona.

"If you are trying to argue that in aggregate the demand for energy in canada drops because of high adoption of residential solar which then passes off clean energy to the US"

Well... ya. If on sunny day 10 000 homes in the GTA offset 1000W of energy, that'a 10MW more power that CND can export. Furthermore, the GTA has massive energy storage capacity from an artificial lake by the falls so the 10 MW doesn't become a rounding error.

.... but 10 MW is piss. Solar in CND is piss.


You know, when I was researching my system and if it would be worthwhile there were literally dozens and dozens of people who were adamant it couldn’t work here. Too much snow, too tight a valley, electricity already kinda cheap.

I went ahead anyway because I’m a “I’d rather have hard numbers than speculation“ person, and it was literally $0 of my money.

Here we are 18 months later. I have all the hard data, numbers and proof that this system will cost me $0 in the short term, make me over $20,000 in the long term, requires no maintenance and is great.

And yet there are still people like you telling me it can’t work.

I’m proving it does, very well. Panel prices are falling so fast your “last time I looked into it” is woefully out of date.

Why are you denying reality?


Talking about hard numbers without a real "hard number" in your comment. 0$ upfront - how much did you pay for the system / what is the size of the system / whats your azimuth and what are you paying for electricity currently. Its super easy to run the math on this stuff - not rocket science - theres even a free to use API that generates your monthly production estimates.

I run energy modeling - I ran the numbers last month with the new programs and newest panel prices. 12-14 years without any op costs and a 3% per year escalator on electricity. You can get it down to 8 years if you have a great spot without having to put on ballasts but it isn't braindead yes for everyone (especially if they have to watch their money).

Current price: 7.6 kW AC; Installed: 26,155.65 - 5,000 Grant = 21,155.65$. << Hard numbers.


The numbers are in my original post.

We got 7.6kw installed for $13,000 CAD. I ordered everything myself, had a local installer do it on his weekend, paid an electrician $180 to pull permits and actually wire it into the main house panel. All inspections complete and legal. $5000 grant $8000 interest free loan.

The system makes 7.76Mwh per calendar year. Electricity here is 0.13/kwh, and already pre-approved go up minimum 5% per year. It just went up 6% for 2026, 16% for those out of town.

So the system makes right on $1000 of power every year that I don’t have to buy. We’ll put that onto the loan for 7-8 years , then get at least $1000 a year for the 20 or so years remaining of the system life.

I’m nothing out of pocket, and I’m just putting the same into the loan for 7-8 years that I would have paid in electricity anyway, so no difference.

No brainer.

My house now uses net zero energy ( disconnected natural gas entirely)

I have no idea where you’re getting a quote for so high. Even the highest I got was ~$20k, and that was over 18 months ago.


Those numbers are pretty low for Canada (well done on getting a good deal) - though it sounds like you are doing all the work yourself so thats sweat equity and the difference is the margins / work that installers put into the equation.

I don't think what you are providing as an example is what most people are doing. Most people are going through residential installers and not doing all the effort you did to bring down costs.

I commend your effort but it isn't what most people would be doing or paying for and represent otherwise isn't quite honest for people looking to get numbers for their own install.


Friends got a near identical system just out of town after seeing the success of ours.

Fully hands off solar company, $16.5k fully installed, permitted, inspected for 7.6kw on the roof.

They also got the $5k rebate and $10k interest free loan. Their power price just went up 16% in 2026, so they’re extremely happy to have the solar to insulate them from that.

Of course the panels are now a good bit cheaper than when I bought them, and cheaper than when my friend did already.


The quotes for solar on my home in the US ranged between $40,000 (local company) and $120,000 (Tesla). How did you get solar installed for only $13,000?


Those numbers are meaningless unless you specify what you get in return.

It is like saying that you pay $30,000 for a car. But the most important question is: For which car?

Also, if the installation services are so expensive, you can always install everything yourself.

Study how to do it, get the tools and materials, and then do it. It would be time-consuming, challenging and perhaps it would carry extra risks. Absolutely.

But it is not rocket science. It can be done. As long as there is a motivation to do it, i.e. a good value you will get out of it in return, it should be a valid approach to consider, in my opinion.


They are in Canada.


>Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.

€13.000 for this still seems expensive.

Are there tariffs on Chinese PV in Canada?


Most rooftop install costs are labor. The PV is now a minimal slice of it. Which is why mandating solar on new construction is such an important policy: don't make two sets of laborers clamber around the same roof.


13k CAD is €8.000


> Solar prices in the US are criminal, protecting oil and gas who bought all the politicians.

Are you saying that because you assert cost is driven up “artificially” by taxes or other structural headwinds? Or are you saying that fossils enjoy an advantage due to lopsided subsidies? Or something else?


What is the underlying reason in the US though? You would think if they are artificially inflated prices the market would fix that. What I’ve found is that a large part of the cost is the actual labor for the installation, how are other developed countries getting around this?


It's mostly due to higher "soft costs" such as complicated/slow permitting and high customer acquisition costs. Australia has a higher minimum wage but much lower costs to get a rooftop system installed.

"How to cut U.S. residential solar costs in half"

https://pv-magazine-usa.com/2025/07/11/how-to-cut-u-s-reside...

Birch points to Australia, where he said the average 7 kW solar array with a 7 kW battery costs $14,000. That equates to $2.02 per W, with batteries included.

“You can sell it on Tuesday and install it on Wednesday, there’s no red tape, no permitting delays,” said Birch.

...

In the United States, that same solar and battery installation averages $36,000, said Birch. Permitting alone can take two to six months, and the cost per watt of a solar plus storage installation is up to 2.5 times the Australian price, landing at $5.18 per W.


Those numbers for Australia are very out of date.

My Dad in Australia just got 10.6kw fully installed and running for $4,000 AUD


Was this on his roof? Were there government subsidies?


Yes and yes

Australia is spending tax dollars to get solar on every roof in the country instead of building coal or nuke plants. Now people are getting free power as a result.


I wish we did that.


Mostly by giving people free money to install them so they go on the internet to say how cheap they are.


That might be cheaper than grid upgrades though. Even though some people might get upset that somebody else is getting something for free.


> Canada here. 7.6kw on our roof for $0 out of pocket thanks to $5k grant and $8k interest free loan.

So solar only makes sense when it's nearly completely subsidized?

That's not the statement you think it is.


US also tariffs Chinese EV makers out of the US market so they can keep peddling the fiction that EV sucks or China can't build anything we can't.

This has the same corrupt nexus with the anti-renewable mantra. Essentially subsidize oil and gas under the table and punish renewables then tell the electorate that the latter is worse than the former.

Instead of giving Americans free choice American automakers pay American politicians to prop up their uncompetitive prices and subpar offerings. All while they take in huge private profits. American workers could work on foreign automobiles, just as they do with other automakers not from China. It's not about workers, it's not about national security. You don't even have to go into all the environmental concerns that of course disproportionately affect poorer individuals.

It's corporate welfare. And yes, it should be criminal. At the very least, if the American people are going to inflate CEOs salaries they should have seats on the board.

This is actually not a wild idea. You might be surprised to find who one of the largest shareholders of the Volkswagen group is. It's not like that is an obviously mismanaged socialist hellhole company, it's a perfectly competitive and well regarded car company.

Americans need to start demanding more equity or oversight in operations their governments are already paying for. The fact most Americans think this amounts to communism just means more people have to call out the money is already flowing.


I’m really happy Canada just dropped the Chinese EV tariffs.


It's criminal to not hand huge subsidies to people like you who are already likely well-off, so you can generate passive income for the rest of your life?


Oil and gas subsidies in Canada dwarf whatever pittance is tossed out to renewable energy. People getting an interest free loan for rooftop solar may be well off (they own houses), but I guarantee the CEO of TC Energy is doing even better.


A few things

If enough people adopt solar, it gets cheaper, and everyone get cheaper power, or even free like Australia.

Tax dollars could be spent on new coal or nuke plants, or to incentivize solar installs. Which one is the right future? Do new coal and nuke plants result in free power like Australia?


OTOH, oil and gas prices in Europe are criminal, so there's that.


Europe has to import both, and the sellers tend to abuse Europe's dependency on it. Europe has what is becoming a survival interest to replace oil and gas as soon as possible.


We have similar problem with prices being high despise renewable energy being cheap ;/


Missing from your calculus is the cost of creating, cleaning, maintaining and eventually replacing the hardware. None of that is "free" - it is merely externalized to a vulnerable population or to your future self.


Missing from your calculus are the healthcare costs of every person in a country breathing in fumes from electricity plants that burn coal and fumes from cars that burn gasoline.

https://www.sciencedirect.com/science/article/pii/S266675922...

(And a gazillion other studies.)


Not supporting OP because I think hes backwards on the matter. However in Canada the electricity that is being burned isn't coal based - so you need to compare the actual grid not some hypothetical grid.


Canada's alternative energy source is very rarely coal (no where near me at least) but a lot of the grid capacity is coming from LNG outside of ON/QC. BC has a bunch of rivers and other water features but has been highly reluctant to build out hydro supply, as an example.


Unlike the UK (which mothballed and eventually tore down its coal power stations) there is still a whole bunch of coal power online in Canada.

Lingan Generating Station would be a typical example. Big thermal power station, built to burn local coal, realistically the transition for them is to non-coal thermal power, burning LNG or Oil, or trees or whatever else can be set on fire. If they burned trash (which isn't really a practical conversion, but it's a hypothetical) we could argue that's renewable because it's not like there won't be trash, but otherwise this is just never going to be a renewable power source.

Canada is a huge place, so I don't doubt that none those coal stations are near you (unless, I suppose, you literally live next to Lingan or a similar plant but just aren't very observant) but most of us aren't self-sufficient and so we do need to pay attention to the consequences far from us.


>there is still a whole bunch of coal power online in Canada.

Ontario, Quebec, BC and Alberta, the four largest provinces by population and a heady percentage of the land area, have zero coal power generation facilities.

Ontario is mostly nuclear supported by hydro, with an absolute fallback of natural gas. Quebec is overwhelmingly hydro + wind. BC is mostly hydro. Alberta is mostly non-renewables like natural gas, but phased out its last coal plants.

If someone is in Canada, odds are extremely high that there is no coal plant anywhere in their jurisdiction. I also wouldn't say that there is a whole bunch of coal power online -- they're an extreme exception now.


To me "a bunch" is when it'd be tedious to list them. For a few years the UK had few enough that you could list their names, then gradually four, three, two, one, none. Canada as a whole isn't in that place yet, though it doesn't have plans to build more of these plants and they will gradually reach end of life or transition to burning something else.

Coal isn't one of the "convenient" fossil fuels where you might choose to run electrical generation off this fuel rather than figure out how to deliver electricity to a remote site, coal is bulky and annoying. Amundsen Scott (the permanent base at the South Pole, IMO definition of remote) runs on JP-8 (ie basically kerosene, jet fuel), some places use gasoline or LNG. I don't expect hold outs in terms of practicality for coal, it's just about political will.


"For a few years the UK had few enough that you could list their names, then gradually four, three, two, one, none"

Sure, it's embarrassing that we still have any coal plants. But really, there are only eight small units remaining, located in the provinces of Nova Scotia (4), New Brunswick (1), and Saskatchewan (3). Every other jurisdiction abolished them.

Maybe small nuclear will be the solution for these holdouts. The fact that Alberta held onto coal for so long, and never built a nuclear plant, was outrageous.


Oh, OK, eight is fewer than I thought, my impression was a dozen or more. I take it back then.


That's a fair point, though I think OP's recommendation to switch to solar is also to people outside Canada and most of the world is still burning fossil fuels to generate electricity.


OP probably shouldn't have been replying to a Canada based question.

You are being very aggressive and confrontational in your comments and people are responding in kind.


Not really. People are angry because it is likely their first time hearing a contrarian narrative about solar energy, which likely challenges their own sunk-cost fallacy as solar panel owners.


Everything needs to be created, cleaned, maintained, and eventually replaced. You are acting like this is some sort of surprise.


I have roof top solar. I have never had to clean or maintain them in any way. Same with my friends who have roof top solar. The worst I’ve heard of is a microinverter failing, which was covered by warranty.

My gut response to your post was also aggression, not because you’re preaching uncomfortable truths, but because you’re repeating fossil fuel lobbyist talking points that I’m getting really tired of seeing all over social media.


How long have you had your system - biggest risk point is year 10-12 and then 20-24 on inverter failure replacement which is fixable but just stretches out your payback period.

Im with you I hate the people who preach fossil fuel talking points. I also don't like the shady solar sales people who say solar is a no brainer - they are just pushing product to install on your roof. It is a pretty good product but not 100%.


They're trolling and people keep feeding them so they keep posting.


I'd disagree the fervor is religious.

I think it's more frustration. Pointing out there is a maintenance cost to infrastructure is silly and doesn't add to the discussion.

We all know materials have to be shaped into machines to extract energy.


Simply ask to quantify the cost of shaping those materials into machinery, respective to other means of energy production. You will be met with hostility and scorn, accused of all sorts of improprieties, and ejected from the tribe, without ever receiving a data-supported answer.


Because it's such a weasel "just asking questions" thing to do.

If you had a concern about the material costs of renewables you should know what they are and if you wanted to have a good faith discussion, you'd also be able to compare against legacy energy material costs.


You have received data from several people in this thread alone. Have you updated your opinion accordingly?


The vagueness of your statement makes it impossible to discern any actual point outside of some broad anger/frustration packaged as humor.


Especially when they are offshored to China. https://www.nature.com/articles/s41561-023-01308-x


Those costs can be safely deemed as 0, especially when you use Reed Elsevier.

One should definitely think about the children when choosing coal/gasoline vs. full electric. In fact we did and we have an electric car, replaced our gas cooking top by induction, and our gas-based heating by a heat pump. Last time I boarded an airplane was in 2019 I think.


> In fact we did and we have an electric car, replaced our gas cooking top by induction, and our gas-based heating by a heat pump. Last time I boarded an airplane was in 2019 I think.

Fantastic virtue signaling. Of course totally devoid of any mention about the individuals picking raw materials for those electric car components though, since they're not "our" children.


> Of course totally devoid of any mention about the individuals picking raw materials for those electric car components

You think elves drill oil and mine coal?


Strange that in your comment history you're all about the democratization of technology, but you seem to be against solar of all things? Talk about decentralized power!


The only thing strange is trolling comment history instead of rebutting the argument made on its own merit.


Roof maintenance is a need in Canada regardless of the presence of solar. Solar roofs do demand additional maintenance but the benefits over relying on natural gas for power (which is the alternative in Canada outside ON/QC) is worth it.

I will stand by your statement from the philosophical point of view that nothing in life is free and everything has its trade offs - but this is a pretty clear positive. In addition, Canada has pretty decent workplace safety enforcement for the sort of workers that'd be doing the maintenance - it certainly isn't perfect but it is something that Canadians seem to find important.


Panels have warranties of over twenty years now. They pay for themselves much earlier. You probably have to replace the inverter earlier, but that’s not a huge expense. I don’t know anybody who lives in a place where it rains who cleans the panels on their roof.


Oh, okay. Does a warranty cover sweeping snow off your panels and washing them many times throughout the years? I guess if one does not value time, then solar panels could be considered "free" - but this is a bizarre sacrifice.


Lies. I'm using solar panels since 2022, still producing same peak energy and not cleaned them once. Some companies/electricians will try to sell you a cleaning and maintenance service for ~80-100EUR/year here but it's basically throwing money.


I live in a fairly arid place (Bay Area) where it rains in winter but gets quite dry and dusty in the summer. I've had rooftop solar since 2016 and have noticed that generation decreases by as much as 8-10% when the panels are covered in summer dust.


I wonder if it's worth setting up a sort of sprinkler system so you can easily clean it by opening a valve. Maybe add a pipe with some holes in it to the top of the panel, and some flexible hose to hook it up to the next one.


Just spraying dust with water will not remove it. Detergent helps, but most of the cleaning effect is done by mechanical agitation, eg. wiping the glass.


Here it's not so dusty, but in spring there can be a ton of flying pollen and yet, our not so abundant rains (generally speaking, there are more and more stormy episodes lately once a year) are enough to clean it up.


Where are you getting this maintenance schedule from?

I haven’t touched ours, they are clean and have been going fine with zero maintenance, though admittedly it’s only been a year.


> I haven’t touched ours, they are clean and have been going fine with zero maintenance, though admittedly it’s only been a year.

> Where are you getting this maintenance schedule from?

The solar panel owner does not know the required maintenance they are now permanently responsible for. Ibid, your honor.


You’re being extremely argumentative all over the comments to this story. Do you yourself own any solar panels? Your ceaseless naysaying constantly contradicts people’s lived experience (including mine) as owners.

Focus on solutions, not trying to be right. It’s aggravating.


> Your ceaseless naysaying constantly contradicts people’s lived experience (including mine) as owners.

Also, like, every study on this matter. The efficiency drop from being dirty for vaguely modern solar panels is _tiny_; below 5% and potentially below 1%.


They are clean, I can see that and could wipe them if I needed to. The power output is the same.

Where are you getting this maintenance schedule of yours from?


> Where are you getting this maintenance schedule of yours from?

Their "Anti-Solar Talking Points" handbook from Big Oil.


As above, cleaning solar panels is generally close to pointless.


I got solar panels installed two years ago and I've washed them once. I'm still getting great production. Are you trying to convince yourself that maintaining solar panels is difficult? Because it isn't.


> I got solar panels installed two years ago

> I've washed them once.

> I'm still getting great production.

Thank you for reiterating my point.


So let me get this straight, I save hundreds of dollars a month, I drive my cars "for free", I get paid at the end of my net-metering year, and somehow this is a bad deal because I've wanted (not needed) to wash my panels once? It sounds like you optimize your life around not maintaining the things around you which is fine, but I'd much rather save thousands of dollars.


You don't bother with the snow. Winter is low production energy due to the suns positioning - it melts in the spring and your back to producing. Most solar power is between march - september anyways.


Washing solar panels _at all_ would be fairly unusual, and arguably pretty pointless, particularly given they're so cheap now; you're looking at, optimistically, a 5% efficiency improvement, but many studies say more like 1% in practice.

If you're in a place that gets significant snowfall such that they're often covered then production during winter is likely to be fairly marginal anyway, so may not be worth your while.


Why do you think that level of maintenance is needed?


I've had my system for 10 years and maintenance has literally been 0. Rain and snow clean the panels. Panels themselves warrantied for 30 years but will likely last longer.

Roof-based panels also take on some roof wear, increasing longevity of roofing as well.


I’ve had the system 18 months now. I’ve never once cleared snow or washed them. We get tons of snow.

Zero maintenance.


Solar panels last practically forever. Despite the official lifetimes of 25-30 years, that was a conservative estimate for budgeting purposes, and they're still working after that time, with moderately reduced efficiency (around 70-80%).


Yeah of course solar is cheap if you get everyone else to pay for it.


It's not always a no-brainer. If you live in a good established neighborhood in a warmer climate you'd have to remove tree coverage. Even if you did that, it's the other guys not oil or gas that will make it a hassle.


New panels are much less impacted by shade. Friends out of town just installed the same setup as ours, didn’t want to cut down three monster Doug firs shading their roof in summer.

Made 6.9Mwh in 2025, only just less than ours with no shade at all.


I mean physics would dictate that shade impacts performance but if you are able to break the laws of physics I am impressed!


Shade on older solar systems would impact energy production disproportionally. You would typically see dramatic reductions like 50%-80% reduced output due to 10-20% shade. New shade-tolerant solar systems are closer to being proportional.


This is because a string of panels in series are limited by the weakest link — if one cell is fully shaded, it blocks electricity flow through it, and therefore through the whole string. Bypass diodes mitigate that to some extent. But with electronics costs still falling, it's now possible to use more smaller inverters to connect the solar array to the grid, each one with its own separate string, or even an individual panel (which is a series string of cells).


And bifacial panels with higher efficiency were invented to work around that physics.

Real numbers don’t lie.


No one works around physics. You work with physics or you don't work.

What you are describing is adding more solar capability to counter act the shade. Also the other part of it is that the panels work in parallel/not in series or alternatively don't dis activate as many conversion points as possible.

Physics never lies - they are the only laws that you cannot break.


Houses where the roof is completely in the shade from trees? That's not a very common sight.


It's a very common site and greatly increases the value of the property.

It reminds me of when I was telling my Canadian friend how my pool gets a lot of leaves in it from all the trees and they said that was unfortunate. In Austin the pools get too hot to actually swim in if they aren't shaded.


Depends on the city. Here in Atlanta we are a "city in a forest" and for older neighborhoods with mature trees it's more common than not.
