Battery

A solar battery is a device that you can add to your solar power system to store the excess electricity generated by your solar panels. You can then use that stored energy to power your home at times when your solar panels don't generate enough electricity, including nights, cloudy days, and during power outages.

Most solar batteries come with power output ratings of about 5 kW, which means they can provide enough power to run a refrigerator, clothes dryer, and an electric stovetop at once. A battery's size determines how long your appliances can run.
