Solar Attic Fans
Solar Attic Fans for Attic Ventilation
Solar attic fans quietly and efficiently provide attic ventilation and can reduce the temperature in your attic by up to 40 degrees during the summer. By venting hot air out of the attic, your air conditioning system doesn’t have to work as hard to cool the living areas of your home. Your solar attic fan will run the hardest when the sun is strongest and never cost you a dime to operate.
Solar Attic Fans Keep Your Attic Cooler
Even if your roof has vents installed, there may not be enough air circulation to remove enough heat from the attic to prevent it from doing damage to both your roof and your HVAC system. Excess heat in the attic will radiate heat back into your living environment, forcing you to use more air conditioning, increasing your energy costs.
Unlike attic vents which are passive, solar attic ventilation fans actively draw heat out of your attic. A solar attic fan placed at the roof’s ridge or in a gable end will pull air in from outside, force it to move through the entire attic space and escape through the attic vent. These types of fans do not require any extra electrical wiring or structural changes because they run on solar power. Plus with solar, there is no operating cost and you can claim a 30% federal tax credit.
Solar Attic Fans Increase The Effectiveness Of Your Insulation & Radiant Barriers
There are three types of heat that affect your home’s comfort:
Radiant heat is heat moving from one object to another along a line of sight. That is why you feel cooler when standing in the shade. The radiant heat has been blocked although the ambient temperature is only a few degrees cooler. A radiant barrier stops this kind of heat from entering your attic, but it does not effect the other two types of heat.
Conductive Heat is heat moving through materials. Insulation slows the heat transfer through your ceiling into and out of living areas. Extra insulation without proper venting can actually add to temperature increases because heat is trapped in the insulation.
Convective Heat is heat moving through the air. A solar attic fan vents this convective heat to the outside. Proper ventilation removes the excess convective heat build-up that is not addressed by your radiant barrier and insulation. As the heat is exhausted, the workload of your air conditioning system is reduced, thereby saving energy costs and even extending the life of your air conditioning system.
When considering energy savings alone, a solar attic fan will pay for itself. A solar attic fan will last a lifetime too, so you won’t need to replace it anytime soon!
