Wow, $0.042/kWh is commercial/industrial pricing!
I'd install a Powerwall, charge at night, and go battery power by day.
Quick math, opportunity cost excluded...
Powerwall $8,000 installed
Flat rate electricity plan at $0.11/kWh
360 kWh per month from the Powerwall at $0.042 /kWh = $15.12
You'd save about $25/mo by only consuming the cheap energy.
...26 year payback. Nevermind.
