If you get a tesla-based system, it comes with a powerwall. W/o energy storage the solar system isn't great anyway. A battery like power wall can do a few things:

1. Charge when it's cheapest (day for Solar), then top off from the grid off-peak hours

2. Even out supply and demand mismatches

3. It could probably run a Fridge for 2-3 days (AFAIK)


Number of states in our country minus the number of Supreme Court Justices?
