Outage preparedness guide
Will Solar Panels Work During a Power Outage?
Panels on the roof do not automatically mean power in the house when the grid fails.
Most grid-tied solar systems shut down during a utility outage to protect utility workers and equipment. A compatible battery and control system can safely isolate the home and create a protected source of power for designated loads.
What determines the answer?
Safety comes first
Anti-islanding protections prevent a standard grid-tied array from energizing utility lines during an outage.
A battery forms the protected system
Storage and control equipment can isolate the home and coordinate solar generation, battery charging, and backed-up circuits.
Weather still matters
Solar production changes with time of day, clouds, shade, season, and array condition, so outage planning must include realistic generation.
Frequently asked questions
Can solar recharge the battery during an outage?+
A compatible system may recharge from solar while isolated from the grid, subject to system design, available sunlight, battery state, and operating limits.
Does switchover happen automatically?+
Many battery backup systems are designed for automatic transition, though response and supported loads vary by equipment and configuration.
Can I run air conditioning?+
Possibly, but air-conditioning loads and startup demand can require substantial output, capacity, or load-control equipment.
