Battery Storage

You can store power generated by your home rooftop solar system — or from the grid when electricity prices are lower — to be used at a later time. If an outage is imminent due to a storm or shut off event, some storage providers are able to send a signal to your battery to fully charge before the outage, in preparation to provide backup power. You can use the energy stored by your battery to power your home when the price of electricity from the grid is more expensive, at night when your solar system isn’t producing (if you have solar), or during an outage when you need backup power.

Key components of a battery storage systems are the battery, the inverter, the wiring to your home’s electric panel, and energy management and communication software.

We recommend talking with your storage provider about sizing and programming the battery to meet your energy goal(s): You can use your battery to provide backup power for your essential electrical needs and/or medical equipment during power outages. You can shift your use of grid energy to lower-price times of day to see bill savings. If you have your own home solar system (or other renewable generation) you can also: Capture your solar energy and use it later to power your home. Send excess renewable energy back to the grid during more expensive “peak” times to see more bill savings.
