Solar Attic Fans The Benefits of Attic Ventilation




Solar Attic Fans Cool Your Home in the SummerCool your house in the summer

During the peak summer months, your attic’s temperature can rise to 160° or more. This heat build-up can then raise the temperature inside your home and increase the amount of electricity used by air conditioners and other cooling equipment.


Installing a Solar Attic Fan will help remove the heat build-up in your attic and bring your attic’s temperature down closer to the ambient outside temperature.


The reduction in attic temperature will also benefit the homeowner by preserving and extending the life of the roofing and attic construction materials. Additionally, hot air in your attic can then heat the metal exterior of your HVAC ductwork and consequently heat the air passing through it, causing your air conditioner to work even harder.




Solar Attic Fan Prevents Mold and Milder in the WinterRemove moisture and protect your house in the winter

In the winter, a typical attic absorbs up to 28 gallons or more of water from the warm, moist air rising from the inside of your home and collides with the cold underside of the roof. U.S. Sunlight Solar Attic Fans provide the air circulation which prevents the moist air from condensing on the surface, keeping your attic drier and helping to prevent mold and mildew from forming inside your attic and from ice damming on your roof.


Moisture in the attic can also lead to other troublesome problems. Humidity can cause saturated insulation, sheetrock pops and truss uplifts, which can cause damage and cracks to the drywall inside your house.

control your solar attic fan after dark with the Solar ControllerIntelligently simple attic ventilation

The Solar Controller allows you to power your solar attic fan with free, abundant solar power when you need it most while also giving you the option to run your fan after sunset using only a small amount of house electricity—all without the noise and operating expense of an outdated traditional electric attic fan.




Use house electricity to function similar to a battery backup for your solar attic fanPower your solar attic fan after dark

When there is no sunlight available to power the fan and the Solar Controller has the optional house power connection enabled, the Solar Controller will cycle house electricity for 15 on, 15 minutes off every half-hour in order to power the fan. This will allow your attic temperature to continue to drop after sunset and help remove the hot, stagnant air that can build up on those warm summer evenings.





Monitor temp and humidity levels in your attic with the Solar Attic Fan Controller hand held remote controlReal-time status updates

The Solar Controller also includes temperature and humidity sensors which enable the fan to intelligently run at the most optimal times to reduce attic temperature and moisture. It also helps prolong the life of your fan by shutting off the motor when conditions are stable and attic ventilation is not necessary.
