I just wanted to get an idea of how many batteries people are getting for their house. I know it's depends on many variables, like much the house uses, how much they generate etc etc. I've been looking to get into solar, but with the new changes that PG&E is doing with the rates I think the Powerwall is becoming necessary. I'm just not sure how many I would need. I look at my usage from month to moth and I use around 10kwh a day at most. So I think one 7kw powerwall will be enough but i'm thinking I should probably get two just in case.
