What is the benefit of a solar attic fan?

The attic can be a very hot and inhospitable place. As the sun beats down on a roof, the heat collected on the surface heats the air trapped in the attic. The trapped heat and humidity can eat can crack and bow ceilings and create condensation, mold, and rot to the roof itself. Traditional electric attic fans use grid electricity to pump the superheated air out of an attic. This action cools the attic and draws out moisture. A cooler attic results in lower cooling bills, however traditional electric attic fans can consume those savings.
 
Solar attic fans create the ventilation offered by traditional attic fans in a safe and environmentally friendly way. Solar attic fans do not draw any outside electricity after installation. Because of their lower speeds, these fans do not cause excessive negative pressure inside drawing conditioned air out of the home or harmful exhaust gasses like carbon monoxide back in. Many solar fans have lower profiles and guard against driving rain. Solar attic fans are a great way to gain efficiency in your roof.
