Not without a fully-charged backup battery. Grid-tied solar systems are required to shut down in the event of a power outage. This is a safety precaution put in place (UL 1741) to protect utility workers from the threat of electrocution. Your home’s solar system produces a lot of electricity – electricity that will travel onto the grid if your home doesn’t consume it. That same electricity poses a substantial threat.
Outages are usually short, meaning you don’t miss out on much in the way of lost savings, and your system will start producing automatically once power is restored. If you’re interested in seeing the cost of adding a backup battery backup to your new (or existing) solar system, let your account manager know. We’re well versed in the benefits of battery backup.
