Solar power in San Francisco, California

PG&E provide net metering to their solar customers in San Francisco. Net metering values exported solar energy at the same value as energy from the grid. When more energy is exported than consumed you will not only wipe out your bill but credit will be carried over at the same rate to future months. Under the new NEM-2 rules customers must switch to time of use billing, left over credit at the end of the year is only valued at about 3-4 cents and is deposited into your account. These rule changes only reduce returns by about 10% and solar is still an excellent investment.

On top of net metering there is also a federal level 30% solar tax credit covering 30% of the cost of the system. With net metering and the 30% tax credit under threat San Francisco residents need to act now to receive the benefits of these incentives.
