Frequently asked questions
Do solar panels work during a power outage?
A standard grid-tied system shuts off during an outage for safety. To keep power you need a battery or backup system designed to island your home.
Is a home battery worth it?
It depends on outages where you live, time-of-use rates and how your utility credits exported solar. Batteries add backup and can raise savings under net billing or TOU rates.
How long do home batteries last?
Check the warranty: battery warranties usually limit years, cycles or energy throughput, whichever comes first.
