Battery Storage
Battery Storage
Make your home more resilient during power outages and make the most of your solar electricity system.
Benefits of Battery Storage
Battery storage offers a convenient and easy way to provide electricity to your home in a power outage.
Resiliency
Take the stress out of electrical outages by having a backup source of power
Ongoing revenue
Battery storage systems can generate additional credits or payments from your utility
No hassle
Power is stored in an inconspicuous box attached to the wall and doesn’t require separate fuel, need mechanical upkeep, or produce on-site emissions
Complements solar
Charge your battery with solar electricity and then use the battery during times when the solar panels aren’t producing energy
The Technology
How It Works
The battery is charged by solar electricity if you have solar panels, or by utility-supplied electricity if you don’t. If the battery is paired with solar electricity, energy generated during the daytime and stored can be used to power your house at night. You can work with an installer to size a battery storage system to best fit your house’s needs and to power critical loads, such a a refrigerator, in an electric outage.
Important: If you have a solar electric system and want to power portions of your home and/or re-charge your home battery with solar energy
during a power outage, talk to your installer about islanding capability.
Battery storage is ideal for:
Homes with solar electricity | Generator replacement
