Thanks! What would you suggest for solar here in Los Angeles. We have an outage every 5 years so I am not worried about that. 1300 sq. foot house. Normal - - tvs, appliances with AC. Good sun coverage - no big trees in the way between 11am - 6pm. Thinking of going with Telsa, but not sure we need a powerall if we gain too much and can get a credit from power company. I would lean toward zero powerwalls. Your suggestion? zero, 1 or 2 powerwalls.........? Thanks
