The Cooling Sun
In most homes in the south of the country keeping the attic cool is a vital objective. Not only is this beneficial for comfort but also in keeping down the electricity bill. There are many ways that is achieved but the most common is the installation of a clay or pressed-concrete roofing material to both reflect and absorb the heat and keeping it from penetrating to the attic. However, even roofing materials need help and homeowners install vents and reflective foil to help cool the home.
Another aid for ridding the attic of heat is a venting system driven by a fan. However, to keep the fan running requires electricity and this will definitely add to the electrical bill. But why not use the power of the sun to clean up the problem caused by the sun?
The Solar Powered Attic Fan is designed to use the sun’s energy to power the electric fan and clear the attic region of the build up of hot air. Designed as a roof-mounted vent the unit generates 11 amps of electricity form an array of photovoltaic cells. This is enough power to power a fan that has the capability of 850 cubic feet-per-minute. Larger units can provide up to 1250 cubic feet-per-minute for longer or higher roofs.
The great thing about a solar-powered unit is that it will run continuously when it is needed - in the sunlight. It will also generate power on shady days so that there will always be airflow through the attic.
When you combine the three methods of heat dissipation it makes for an efficient way to get the heat out of the attic. The roof is the first line of defense, the foil will reflect up to 95% and the Solar Powered Attic Fan drives out the heat that gets through.
