[oil pan 4]

I had to provide proof my name was on the house. Otherwise had to pay cash for my solar.

Small areas inside California are nearing max solar capacity even with as few as 5% of homes having solar because everyone pointed their panels in the same direction for maximum overall production and in the middle of the day no one is cooking, charging thor tesla or doing laundry most days of the week so very little of the production is consumed by the home.
There's 2 ways to fix too much solar. Shut'em off which sucks, or have future installs favor morning or evening peak production.
So if the homes with solar are spread out over a wide area and not clumped together and their peak production all doesn't peak at the same time the power grid won't be flooded with too much solar.
Or power companies can get some battery storage capacity, which they really don't want to do.
That's only scratching the surface of problems created by intermittent power generation.
More solutions are possible but I have not seen anyone actually build them.
