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.

Things to Consider

If you answer yes to ANY of these questions, then battery storage is a good fit for your home

Battery storage is used to power homes during a utility outage or at night if excess electricity has been generated by your solar panels during the day.

Battery storage complements solar electricity. Electricity created from the solar panels can be stored and then used at night or during power outages. During a multi-day power outage, solar panels can recharge your battery if the system is configured with islanding capacity. Talk to your installer about how to configure your solar panels and battery storage to best fit your needs.

Battery storage is a lower-maintenance, cleaner way to provide electricity to your home during a power outage compared to using a diesel or propane-fueled generator.

Battery storage systems can generate additional credits from your utility when paired with a solar electricity system, and can provide an opportunity for payments from your utility when the battery is dispatched at times of peak energy use by the grid.

Depending on your electricity consumption during the outage and the storage capacity of your batteries, you may be able to power essential loads for one or even two days with a residential battery.
