Our solar array is providing electricity for $0.06-$0.13 per kWh, assuming 30 year depreciation. Over half that cost was for a beefy grid tied battery. (We average over one power outage per month in my area. PG&E sucks more than usual here.). Also, because we overprovisioned for storms, we basically get two EVs worth of overproduced electricity at that price. Miles driven from that electricity is cheaper than the gasoline equivalent too.

Solar panel prices did go up a bit in the last few months, but that's because the commerce department inadvertently created a shortage while enforcing the China tarrifs.

On the other hand, I was at the car dealer yesterday, and got to compare used EV prices from January and today. Yikes!
