Overview

Solar Attic Fan is a simple and environmentally sensible solution that can protect your home and even save you money. Powered completely by free solar energy, this sleek and efficient attic vent is compact, quiet and powerful! Simply, the function of a solar attic fan is to improve attic air circulation resulting in a healthy, energy efficient home. Solar attic fans pull hot air and moisture out of your attic extending the life of your roof. In summer months, it keeps your attic cooler helping reduce the load on your HVAC system. In winter months, it prevents moisture build-up and ice damming. Our Solar Attic Fans are one of the best in their class with the highest standards for quality and functionality. We offer a 25 year product warranty – best in the industry.

Attic Venting Extends the Life of Your Roof

The most obvious reason for attic ventilation is to lower the attic temperature during the warmer months. Attic temperatures can exceed 160°F during hot summer days. Proper attic ventilation can reduce those temperatures by up to 40°F. No matter how much insulation is in the attic, heat can still transfer into adjacent living spaces. In fact, extra insulation can actually add to temperature increases because heat is trapped in the insulation. Proper ventilation removes this excess heat build-up. 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.

Reduces the Load on Your HVAC System

Though asphalt shingles are designed to take the abuse of the sun for many years, they are subjected to greater temperatures when the roof decking is allowed to overheat, which is just what happens in an under ventilated attic. In fact, asphalt shingle manufacturers warranties require proper attic ventilation. During the colder months, attic ventilation removes the warm, moist air that heat sources produce. Hot moist air lingering in the attic spaces can condense on the underside of the roof sheathing and rot it out. Moisture in the attic also causes mold to develop on the interior walls. Cold air in the attic space will not affect the temperature in the adjacent living spaces if properly insulated.

Reduces Moisture Build-up in the Attic

In the cooler months, moisture is the most serious concern. Even with the use of vapor barriers to keep moisture from entering the attic, there are air leaks around ceiling light fixtures, bathroom exhaust fans that allow unwanted moisture into the attic. Moisture condensing on the framing members and the inside of the roof deck can lead to the growth of mold, mildew and rot in the roof deck and framing. A good indicator of a moisture problem is rusty roof nails sticking through the roof deck.

How It Works


Heat Builds Inside An Insufficiently Vented Attic. Passive vents (soffit or gable) allow some circulation but do not provide the pressure needed to force out the hot air.


Solar Attic Fan Provides Air Circulation. The solar panel collects sunlight that powers the fan's motor to increase air movement.


Air Circulation Moves Hot Air Out Of Attic Space. Solar powered attic venting can cool your attic space by up to 40 degrees!
