Sunlight powers the fan
The solar panel powers the motor when adequate sunlight is available. Solar operation avoids drawing fan power from the household’s electricity supply.
Solar Attic Fans
Solar-powered attic ventilation
Put sunshine to work above your ceiling.
Solar attic fans use sunlight to help move trapped heat and moisture out of a properly ventilated attic. ECO Solar can help you explore roof-mount and gable-mount options from The Attic Depot.
We look at your attic layout, roof and available intake ventilation before recommending a fan. The goal is a balanced ventilation system suited to your home.
How a solar attic fan works
Warm attic air moves out
The fan exhausts attic air. Adequate intake vents allow outside air to replace it, supporting airflow through the attic.
The whole attic matters
Insulation, air sealing, intake ventilation, roof geometry and sun exposure all affect the result. A fan is one part of the assessment.
Cooling-cost savings and moisture reduction vary by home. We do not promise a percentage saving, a temperature reduction or a fan count before reviewing the attic.
