If you’re a Californian with solar installed before 2024, you use net metering to save money on your energy bill by selling excess solar energy back to the grid.
However, if your family grew or you purchased an electric vehicle, your energy needs probably changed and you’re likely consuming more energy than you produce. If so, you're paying to import expensive energy from the grid.
Adding more than two solar panels to your existing solar system is not an option, as it would cause you to lose your NEM 1.0 or NEM 2.0 status.
