How Does Home Battery Storage + Solar Work?

With constant technological advancements and innovations in the solar industry and developments in home battery storage, like the Tesla Powerwall and SunPower SunVault™, each new product is designed to make life easier for homeowners.


Battery storage can complement your home solar energy system, which utilizes solar panels to harness energy from the sun and turn it into electricity. The system’s inverter then takes that energy and turns it into the right current to power your home. During blackouts and outages, your storage system will provide backup power to your appliances, devices and more so your family isn’t left in the dark. 


While most think homes that are powered by solar energy are independent from the electrical grid, the fact is that the majority of systems actually work in conjunction with your local utility. When your solar panel system produces more energy than your home needs (on bright, sunny days for example), that excess energy goes back to the utility. In contrast, when your panels produce less (on cloudy or overcast days), your home will need to pull in the electricity it needs from the utility. 


This partnership greatly benefits homeowners by reducing and even eliminating electricity costs for solar homeowners and allows them to benefit from net metering. But it also means homes that only have solar panel systems can go dark during blackouts and outages. While these power shutoffs ensure your safety by protecting your home’s electrical equipment and protecting utility workers from any bursts of electric current while they’re working.  


Home battery storage offsets your reliance on the utility during the decline in daily energy production as well as during emergency situations like blackouts. When your home’s solar panels produce more energy than needed during a regular day, that excess energy will charge your home battery first (as a reserve for outages, blackouts, etc.) and after it’s fully charged, any excess power goes to the utility. Later in the day when the sun goes down and your panels stop producing energy, you can utilize your stored energy from your home battery to supplement what you need from the utility.


Here are some details on the home battery options we offer:


Tesla Powerwall 

Your Tesla Powerwall will turn your SunPower solar panels into an all-day resource, reduce your reliance on the grid and store excess energy to use when the sun isn’t shining. You can also monitor your home’s energy production and consumption in real time, optimize your preferences for energy independence and control your system from anywhere. 

SunPower SunVault 

As the only home solar and battery storage solution designed by one company, the SunPower Equinox® solar system paired with SunVault™ Storage lets you become energy independent. You can reduce your reliance on the grid and take control of the energy your home generates to prepare for power outages, blackouts and more.
