Solar is dirt-cheap and about to get even more powerful

$1/W is not a bad price!

For 25 years, at 20% capacity factor, that will generate 96kWh a day, for a total of 876MWh. That's 2.3 c/kWh, not accounting for the time value of money. Call it 4c or 5c/kWh, if you take out a loan rather than paying up front. I dont know of any utility thag charges that little for electricity.

Of course, 96kWh/day is pretty high on the curve of household energy consumption, so most US customers wont get your economy of scale.

Georgia Power charges USD$0.01/kWh for overnight residential electric vehicle charging but that's a pretty niche use case, at least now.

Will they know if half my home is running off my car while it's charging? Could I tell them I drive a lot during the day?

(Assuming one even bothers to use the car as an in-betwee).

I think you're confused with the rated wattage (perfect angle, noon, at the equator) with the actual produced wattage. You will never generate 96kWh/day from a 15-20 kW system.

Uh, we get 60kWh a day in AZ with our 10kW system.
