Solar power in La Mesa, California

San Diego Gas & Electric offers its solar customers an excellent net metering program making solar a smarter, easier choice. Net metering requires SDG&E to only bill you for the power your home drew from the grid subtracted by the amount of excess solar generation exported to the grid. Usually more power is exported than consumed and the customer can use this credit on a future bill or if you want have SDG&E write you a check. The net metering laws sadly did change to NEM-2 so new solar customers must switch to time of use billing to receive net metering damaging returns however, compared to the old system it is only about 10% less profitable and with solar equipment becoming cheaper and La Mesa having so much sunshine net metering will still make a lot of money. If you have a taxable income you can claim the 30% federal solar tax credit. This tax credit can be spread over several years and there are no size limitations to the system. Incentives this generous usually don't last long so it's best to act now!
