During summer, the sun beats down on every Texas roof. The heat is transferred into the attic. Mass insulation such as fiberglass or cellulose slows the heat transfer from the roof to the attic and from the attic to the living areas by absorbing the heat. Once radiant heat passes through the insulation though, it is conducted by the interior ceiling and walls. When interior surfaces heat up, the home suffers from heat gain and the air conditioning system has to fight it for the remainder of the day and partway through the evening as the insulation slowly gives up its absorbed heat from the day.

The Solar Dynamics, Inc., solar attic ventilation fan goes to work when the sun first dawns to minimize attic heat gain. The fan operates almost silently and maintenance free to draw outside air through the attic while the sun is shining. When the sun is trying to heat the attic, the solar attic ventilation fan is actively combating it by cycling fresh air into the attic. The air in the attic doesn’t get the chance to stagnate and gain excessive heat. The fan is on when the attic is getting heated and off when it’s not. It’s a fantastic application of solar technologies that is ideally suited to the task for which it is designed. It operates solely by the free energy provided from the sun.
