if you don't have net metering you should consume as much as you can yourself, cook when the sun is out, run your washer / dryer / vacuum / dishwasher and whatever else you have when you have excess power and minimize during the times the sun is below the horizon. 60% self consumption is doable without too much effort, 70 is work and if you get to 80%+ please let me know how you are doing that.

Also: the big trick to running of renewables is conservation comes first, solar second and finally the grid as a fallback for the remainder.
