How It Works

1

Heat Builds Inside An Improperly Vented Attic

The sun beats down on a homes roof and heats up the enclosed attic space. 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 fans motor to increase air movement. Our PERC solar panels have a front and rear layer to increase efficiency by reducing energy loss.

Air Circulation Moves Hot Air Out of the Attic

The increased air circulation provides the pressure needed to force out the hot air from the attic. Attic venting can cool your attic space by up to 40 degrees saving on energy costs!

A SOLAR ATTIC FAN

Works With Your Existing Passive Vents

If you’ve ever been in your attic, you know just hot the space can get, especially in summer months. The sun beats down on the roof surface and heats up the stagnant air inside the attic. Building codes require homes to have a passive vent system. But, passive ventilation does not provide the pressure needed to force the air through the attic and outside. That’s where a motorized fan comes in. An attic fan placed at the roofs ridge will pull air in from outside, force it to move through the entire attic space and escape through the attic vent.

In summer months, a solar attic fan can reduce the temperature in an attic by up to 40°F!

ATTIC VENTING

Key Concepts

  • Attic ventilation is an important aspect of maintaining the structure of your home as well as saving energy.
  • Improper attic venting can lead to moisture buildup causing mold growth and wood rot.
  • Proper attic ventilation requires continuous air circulation throughout the attic space while preventing moisture from entering.
  • In an ideal venting system, air should enter the attic from the eaves or soffits and escape outside at the roofs ridge.
