SolarCity's residential battery system can help you keep the lights on and fridge cold in a power outage or natural disaster while potentially saving you even more on your monthly utility bills. Our energy storage systems are currently offered in select California markets.
A key benefit of energy storage is to reduce peak-usage charges on your electricity bill. Some utilities offer Time-of-Use (TOU) rate plans in which the price of electricity varies based on the hour of the day. Rates are higher during the afternoon when electric demand is at its "peak" across all utility customers.
A home energy storage system may help you save more money by drawing power from your battery instead of from the grid during higher rates peak hours. You can then recharge your battery during lower rate, off-peak hours.
Your battery system will provide your home with power if the utility grid goes down—such as after an earthquake or other natural disasters. A fully charged battery provides enough energy for your essential needs during an emergency.

SolarCity is making the latest advancements in battery technologies available to you through our partnership with Tesla Motors. Only SolarCity's home backup system uses technology engineered by Tesla, leveraging their expertise in developing battery technologies for premium electric vehicles.
Tesla's long history of research and development has enabled a cost-effective, wall-mounted storage appliance that is small, powerful and covered by a long lasting full 10 year warranty.
The actual battery unit is about the size of a solar power inverter, and will be mounted on the wall in your garage or near your electrical panel.
