Just got through my first summer month under the SDGE TOU tariff structure along with solar production. ($.48/kWh peak, $.22/kWh off peak, $.17/kWh super off peak)
Total use of 1010 kWh.
Total production of 780 kWh.
530 kWh of the use coming from super off peak (300 kWh for 1300 miles on the EV, essentially fuel cost of $4 for 100 miles if not offset by peak hour production)..
Following TOU adjustments, at end of month: $60 credit
Solar with TOU plus EV is just absolutely amazing.
