How Solar Power Works

1. Solar Modules

Mounted on your roof or the grounds of your property, the solar modules convert sunlight into DC power.

2. Inverter
The DC power created by your solar modules is then sent to an inverter (power converter). The inverter converts the DC power to AC power, the same power that is being sent to you from PG&E.

3. Electrical Panel
The converted power then travels to your electrical panel (breaker box), where it is distributed to any electrical loads that are being used in your home.

4. Utility Meter
When extra energy is being produced by your PV solar system it will flow back on to the PG&E grid through your utility meter. Excess energy will cause your meter to run backwards giving you credit with PG&E.

5. Utility Grid
Your utility gird automatically provides you with the energy you need during times that you exceed your PV solar production, during the day when you use more energy than produced or at night.
