Solar power in San Francisco, California

As a resident of San francisco you most likely purchase your power from PG&E.

What solar incentives do PG&E offer in my city?

When your solar system produces more energy than what is being used in your home the excess is sent to the grid and PG&E must credit each kWh at the retail power rate, this program is called net metering. You use your net metering credits to cancel out the cost of energy drawn from the grid at times your solar system couldn't service the electric demand of your home.

What if my solar system exports more energy than my home consumes from the grid?

If you have remaining credit at the end of the month each kWh is still valued at the retail rate and is carried to the next month. At the end of the year if any credit remains each kWh will be valued at the avoided-cost rate (3¢-4¢) per kWh and deposited into your account.

NEM-2 Changes and how it affects my investment?

Since PG&E is an investor owned utility new net metering customers must switch to a time-of-use plan. The worst part of this is that it includes non-bypassable charges of about 2 cents per kWh for energy your draws from the grid.

Luckily these new changes only reduce returns from installing solar by about 10%.

The 30% federal solar tax credit

If you have a taxable income 30% of the cost of installing solar can be claimed as a deduction to federal taxes. This incentive isn't always upfront as it depends on when you do your taxes for the year.

What if my tax liability is less than the cost of my system?

You may elect to receive the full incentive spread out over several tax periods.
