How solar + storage works
Watch this short video to see how combining a SunPower Equinox® solar system with SunPower® SunVault® Storage can power your home with cleaner energy, lower your electric bills and keep the lights on when grid power goes out.

Charge with solar
As your SunPower Equinox® system produces energy, it sends the electricity you're not using to SunVault® Storage and/or sells it back to the grid for a credit on future electric bills.*
- *. Net metering utility credits and incentives vary by location and are subject to change. Your SunPower Dealer can help you determine incentives available in your area. Please visit the dsireusa.org website for detailed solar policy information.

Decrease grid energy usage
at peak times
Intelligent software monitors your solar, home energy use and utility rates to determine which power source to use—maximizing use of solar and reducing peak-time charges.

Backup Your essentials
When the power goes out, SunVault® Storage can provide seamless backup to power your essential appliances, such as keeping the lights on or running your refrigerator.*
- *. The ability to power appliances and electronics during outages depends upon the implementation at installation. "Essential Appliances" are determined by the homeowner before installation and typically include lights, select appliances and outlets for devices. The battery storage system should not be relied upon as a power source for critical medical devices. The life of the battery storage system will vary depending on a number of factors including: the amount of energy stored in the battery, the amount of wattage used by the appliances and electronics connected to the battery storage system, the age of the battery, the battery's ability to recharge during daylight hours due to weather, the frequency and duration of battery usage, and other factors. Battery life will decrease with time and use.
Control your own energy with solar + storage.
