Your evening usage may still come from the grid.
Already have solar?
A battery review starts with how your home uses energy now, not with a one-size-fits-all promise.
What we review
How day and night fit together
Charge from daytime solar
When designed and configured to do so, solar can serve the home and charge the battery during the day.
Use stored energy after solar production falls
The battery can reduce grid imports during the evening, including PG&E's 4-9 pm peak period. The result depends on production, household use, rate plan, battery size and settings.
Prepare selected essentials for an outage
Properly configured storage can support selected circuits. Actual duration depends on battery capacity, charge level, household demand and equipment design.
The right question is not “Can a battery power everything?” It is “What do you want powered, and for how long?”
