Outside transfer switch and a 10-20kw portable generator is like $4-5k. It requires manual switching but it works for us in our hurricane-prone region. Helped with last years 1 in a 100 year winter storm in our southern region.

Battery/solar doesn’t make sense in my opinion. Too many years to break even like this parent comment said and by the time you break even at 10 years, your system either is too inefficient or needs replacing. At least with the portable generator, you can move it with you to a new home and use it for other things like camping or RVing.

Context: I’m in the Netherlands. With taxes, power is around 25cent/kWh for me. For reference: Amsterdam is around a latitude of 52N, which is north enough that it only hits Alaska, not the US mainland.

I installed 2800Wp solar for about €2800 ($3000, payback in: 4-5 years), and a 5kWh battery for €1200 ($1300) all in. The battery has an expected payback time of just over 5 years, and I have some backup power if I need it.

I’m pretty sure about the battery payback, because I have a few years of per second consumption data in clickhouse and (very conservatively) simulated the battery. A few years ago any business case on storage was completely impossible, and now suddenly we’re here.

I could totally see this happen for the US as prices improve further, even if it’s not feasible today.

Is it priceless? I literally wouldn't pay more than $200 to have electricity for a day while the whole neighborhood doesn't. Anything more and I'd prefer to just keep the money in my pocket to be honest.

In my country I've never had to deal with more than 15 minutes, twice in my life. In other countries its sometimes been a day but really I just go on with my life.

Whats funny about that -- is you assume thats the case - but a lot of solar isn't installed to be backup power. With Storage yes, but straight up solar -> no.

It's not the default but you can get it installed that way or get it adapted later (less than ideal if you end up having to replace the inverter).

Yea, that costs extra. My dad went for the natural gas generator.

Well there are other, far cheaper ways to get that.

99% of systems are grid tie, so unless you’re spending another $7k for an ATS and associated infrastructure or you’re 100% off grid, your power still goes off.

For others who aren't up on the lingo:

"An ATS (Automatic Transfer Switch) for solar is a crucial device that seamlessly switches your home's power between the utility grid, your solar panels/battery bank...

And I should clarify that you technically can get away with a less expensive interlock system, but you're still paying a few thousand dollars to have your panel replaced (unless you feel comfortable doing that sort of electrical work yourself).

Making a system non-grid-tie is comparatively expensive, that's why grid tie is so common. People think you add solar + batteries and you're ready for doomsday - not quite.
