Installing a solar fan results in a more comfortable home and lower energy bills. Every home should have proper attic ventilation with solar fans, and because our solar attic fans rely on the sun, they require $0 to run. Plus all of our solar attic fans include a lifetime warranty!

Benefits of a Solar Attic Fan

The purpose of a solar fan is to reduce temperatures inside the attic and other enclosed spaces throughout the year.  In the summer this helps make the living areas more comfortable and reduces HVAC usage, adding to its lifespan and saving energy. Solar fans also help reduce heat which can cause deterioration of shingles, roof boards, sheathing, siding, insulation and valuables stored in the attic.

In the winter solar fans help to prevent moist air from condensing on the underside of the roof, beams, and rafters. Condensation can cause mildew, rotting of wood, and excessive rusting of some components of the roof structure. Solar fans help keep the attic dry.

Our 30 Watt solar attic fan is simple solution to a hot, under ventilated attic. It is available in roof mount and gable mount and is incredibly easy to install.
