Not allowed to have batteries. You have to put excess on the grid and guess what, they don’t compensate you for it.
Untrue as a blanket statement, it depends on the state. With netmetering excess solar power production is either paid for or credited at the wholesale rate.
No compensation for excess? That’s chutzpah for ‘ya.
I’d have thought it would drive the meter backwards; so CA utilities do sometime to prevent gears turning in reverse?
