Expand your existing solar system
Using Enphase technology, you can add more solar, and even batteries,
without losing your current net metering benefits.
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.
The solution is an Enphase expansion system
Enabled by Enphase Power Control technology, you can now install a second, and completely independent solar system to power your home while your existing system exports energy to the grid.
Even if your original system isn’t an Enphase system, you can expand it—or, if you prefer, update it to an Enphase system and enjoy the complete Enphase App experience.
Newly approved by California utilities, it's a smart way to make the most of your solar and maximize the benefits of NEM 1.0 or 2.0.
