Battery storage is the next step to energy independence, but in the meantime, it’s a great way to enjoy peace-of-mind in the event of an event that causes the power to go off, like a utility brownout, cyber attack, earthquake, or even a car accident that hits a transformer. With just solar, your solar needs to shut off so it’s not sending electricity to the grid while there are workers trying to repair it. However, if you have a battery, the energy your solar system produces will be redirected to your battery (ies) and then depending on what you have it wired to, your fridge can still be running, you can power some outlets to charge your phone and computer, run fans, etc. With two or three batteries, you could power your whole home as the solar produces power during the day and charges your battery (ies) for use at night.
And if you install your energy storage along with your solar, you can enjoy a 30% Federal Tax Credit on both. In addition, there’s a rebate from Southern California Edison, which together helps make a battery very reasonable.
Renova is a Certified Installer for the Tesla Powerwall, as well as for Sonnen, the leading battery company out of Germany. Other batteries are offered by other firms, but generally, you should look for a reputable installation company, battery manufacturer and a strong warranty. Battery installation is more complicated than solar, so a company with a lot of experience in battery installation makes a big difference.
A consultant can come to your home and help you decide what you would want to have powered during an outage, and then recommend the amount of battery storage you would need to accomplish that.
