A solar electric system converts the sun’s energy into electricity by producing direct current (DC) in the PV panels. The DC current goes to an inverter, which changes it to alternating current (AC) which then synchronizes with the utility (PG&E) grid.
The electricity produced by the system goes back through the meter to the grid, providing you a credit for the solar-produced electricity. At the end of the year, PG&E sends a True-Up Energy Statement showing net energy usage. Everything else remains the same as before your solar installation, except for saving money and knowing your electricity is from a clean, renewable source.
