Solar power in Ontario, California
SCE offers an excellent net metering program for its customers going solar in Ontario. Net metering requires your utility to record unused power sent to their grid and power drawn from the grid and only bill you for the net amount eg. 500kWh exported to the grid and 500kWh drawn from the grid would result in a power bill of $0. If more power is exported than drawn the utility will credit you 1 for 1 with their retail power price and depending on your choice give you a credit to a future bill or write you a check. Under the new laws new solar customers must switch to time of use billing damaging returns however, only by about 10% and with solar equipment becoming cheaper and solar production being so high in Ontario solar is still a no brainer investment. There is also the 30% solar tax credit covering 30% of all costs(can be spread across several years). With utilities and the coal and oil industry trying to kill off solar the time to switch is now!
