Introducing – Solar Attic Fans

Ventilate your attic with free, clean, abundant solar energy. 

Our line of Solar Attic Fans provide the active ventilation your attic needs to reduce the heat build-up that could reach temperatures of 160F and higher. 43% of air conditioning design load is based on high attic temperatures and it’s this heat build-up that can overheat your air conditioning ductwork and raise the temperatures in your home’s living spaces.

The Solar Attic Fan pays for itself quickly with a reduced strain on your air conditioner, a 30% Federal Tax Credit and extending your roof life up to 10%. Adding a Solar Attic Fan provides active circulation and improved airflow to effectively ventilate your attic space and lower the temperature – giving you a cooler house and a more comfortable living environment!.

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 homeowners 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.

Remove 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.

Solutions for tile roofs, gable/static vents, and crawlspaces

If you have a tile roof, the Solar Powered All Purpose Ventilator is the perfect solution for ventilating your attic. It installs inside your attic behind an existing vent and requires no cutting of your roof or tiles. With the extension of the All Purpose Ventilator product line to include the 1015APV, the options include ventilating up to 1,250 sq/ft or 1,900 sq/ft with a single fan.

Designed and Tested for Severe Weather

Our Solar Attic Fans are designed and tested to withstand high wind and pressure in the most severe weather conditions.  In fact, our Solar Attic Fans can endure a structural load of over 150 psf (pounds per square foot) Here is a quick comparison to a typical hurricane with the estimated wind load:

Intelligently 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.

Power 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 8 minutes 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 buildup on those warm, summer evenings.

Real-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.
