The addition of the Solar Controller with Dual Mode Technology will enable your Solar Powered Attic Fan to run after sunset or when there is no light available from the sun.

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.

Solar Attic Fans by Eco Energy


Eco Energy Guard’s line of Solar Attic Fans provide the active ventilation your attic needs to reduce the heat build-up that will reach temperatures of 140F 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, and extending your roof life up to 10%. A 30% Federal Tax Credit Applies. 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!

Improve your homes efficiency with a Solar Attic Fan

A well-ventilated attic will help reduce your energy costs several ways. Improved air circulation in the summer months will help remove hot air and reduce the temperature of your attic. This will keep the hot, stagnant attic air from seeping through into your living area (Our reflective insulation will stop this process of transfer). It will also help reduce the surface temperature of your attic floor and your interior ceilings.

The reduced temperature in your attic will also assist your air conditioner by keeping the ductwork and the air inside cooler. The resulting effect will be cooler air flowing through your HVAC system and reduced strain on your a/c unit.

Extend the Life of Your Roof

When your attic heats up, the roofing underlayment beneath your roof shingles can also heat up and, over time, become brittle and ineffective. By lowering your attic temperature you can extend the life of your roof and save the expense of repairs and replacement.

Remove Moisture and Reduce Harmful Mold and Mildew

During the winter months, warm, moist air from inside your home rises into the attic and collides with the colder underside of the roof. Proper attic ventilation can help remove the moisture and condensation that can build from this event.

The Solar Powered Attic Fan and the All Purpose Ventilator are great ways to effectively ventilate your attic while saving money on electricity.

Prevent Ice Damming

ice damage

During the winter, warm air moves from the home to the attic. Air that escapes into the attic will warm the roof, melting the snow where it can refreeze as ice-dams at the eves. These ice-dams will cause added weight to open gutters and allow water to back up under the shingles causing damage to the roof, and inside of your home.
