in San Diego was getting a credit for install SOLAR ,He’s a Physicist and did the electrical work himself ..He got his bill down to zero,so they changed the rules ..no more credit for solar..he has a min connection fee each month .They wont let your bill go negative even though you pump elec back to them at lower cost than they buy elsewhere . So I suggested he take out his GAS dryer and get electric dryer and he can still produce enough with his solar to eliminate totally the gas bill . They wont let you not pay something even if your usage is zero ….either way you pay.
If you find a way to reduce usage ..they raise the rate ..they want the same income.
