What is a solar powered attic fan? Solar powered attic fans are attic fans with a solar cell attached to power the fan. The concept behind attic fans is to remove hot air and moisture from the attic space. These fans can come installed with a thermostat to only turn on when temperatures reach a specified degree. They work very well but only if installed correctly. Plenty of ventilation is needed to make these run effectively. Usually soffit vents and gable vents need to be present to allow attic fans to run efficiently otherwise the fan would draw air from inside the house through openings and cracks in the ceiling.
How do Attic Fans work?
Solar powered attic fans rely on a 10-25 watt solar panel to power a small fan and remove hot moist air from the attic space. The fans are mounted at the highest point possible to remove the hottest air in the attic space. They will help extend the life of your HVAC equipment and the life of your roof. Attic fans also help prevent mold and mildew growth in the warm dark areas of your attic.
