Solar-Powered Attic Fans
A solar power attic fan is a roof-mounted ventilation system that uses energy from the sun to remove hot, humid air from your attic. By improving airflow, it helps regulate attic temperatures, reduce moisture buildup, and improve your home's overall energy efficiency—all without increasing your electric bill.
How It Works
As sunlight hits the fan's built-in solar panel, it generates electricity to power the fan. The fan then pulls hot, stale air out of the attic while allowing cooler outside air to enter through existing soffit or intake vents. This continuous air circulation helps prevent excessive heat and humidity from becoming trapped beneath your roof.
