Rooftop solar doesn’t need to pay for a grid. Residential generation is 0.06$/kwh. Residential storage is 0.20$/kwh. My power from the utility is 0.53$/kwh.

If you look at power price increases in CA, you get a pretty good ROI today going solar+battery. But amortized battery prices are going to drop by 75% in the next 5 years (e.g. lifecycle improvement + cost reductions). If you have the capital, it’s going to be a no brained to go residential solar provided you are allowed to disconnect from the grid.
