Battery Backup & Storage

A home battery stores electricity — from your panels or the grid — so you have power when the grid goes down, and in some cases so you can use solar energy in the evening instead of buying it back at night. A common misunderstanding: most grid-tied solar systems shut off during an outage for lineworker safety, so panels alone don't keep your lights on. A battery is what actually provides backup.

How big a battery you need depends on what you want to run during an outage — just the essentials like the fridge and a few circuits, or the whole house. The installer we match you with sizes storage to your real goals rather than selling one default package.
