Solar Attic Fans

Anyone who has had to crawl up into their attic on a hot summer day appreciates the value of a ventilated attic. Fans can help exhaust that hot air from your attic, and a solar attic fan can do it using clean energy from the sun.

When the sun’s rays hit your roof tiles, they heat up…a lot. Some of that heat is transferred from the surface of your roof into the attic space itself. Depending on how well your attic space is insulated, there could be a great deal of heat being transferred into your home.

In summer, this means that your air conditioner has to work that much harder, which can be a real energy drain, not to mention financial drain. If you get that hot air out of there, your air conditioning won’t kick in as often and you could be saving some money.

This cost savings can be diminished when you use an electric fan because some of the energy you’re saving on driving the air conditioner is now driving the fan; but solar energy costs you nothing.

  1. Solar units are self-contained in that they don’t require any wiring. You just literally pop the unit in a hole in your roof and you’re ready to go. This is particularly useful in attic spaces that are very difficult to access.
  2. Since there is no wiring involved, solar units are much easier to install than wired in units. In fact, here’s a video to show you just how easy it is:
  1. Solar energy is a clean, renewable resource that doesn’t cost you a penny. For most solar attic fan models, the solar panels come with a 20 or 25 year warranty.
  2. Solar models are generally considered much quieter than wired versions.
