solar-pro-conSolar Attic Fans, or Ventilators, have garnered quite a bit of attention over the past few years, for many good reasons! In this post, we want to take a look at the reasons you would want to add a Solar Attic Ventilator to your home, as well as the Pros and Cons or choosing to use a sunlight powered unit, versus an electric solar attic vent. If you missed our previous post the reasons to vent your attic, we encourage you to read the Benefits of Attic Ventilation.

What is a Solar Attic Ventilator?

A Solar Attic Ventilator in simple terms, is a powered attic vent fan that mounts to either the flat or sloped section of your roof, or to one of the gable ends of your roof. Once mounted, the solar fans get their energy from the sun, which makes the internal motor turn, resulting in a negative pressure that draws the hot (or cold in the winter) air from inside your attic, replacing it with ambient air from your eave or ridge vents.

Benefits of Choosing a Solar Powered Attic Fan

  • No Need to run Electrical power to Attic
  • 100% Energy Efficient
  • Quick and Easy to Install
  • Reduce Energy Costs for both Ventilation and Cooling Costs
  • Increases Life and Durability of Roof Shingles by Keeping them cooler

Disadvantages of Solar Attic Vents

  • Obviously, if there is limited or no Sunlight, you have no ventilation!
  • Solar Fans have been known to move less Air.
  • Must have Unobstructed Line of Sight to Sun. (Limits install locations)
