18 Watt Solar-Powered Attic Fan

Our 18-watt solar attic provides up to 30% more power than competitor fans resulting in better air circulation in your attic. Reducing your attic temperature also helps preserve and extend the life of roofing and attic construction materials.

A single fan can ventilate up to 1,500 square feet of attic space, reducing the energy needed to cool your home. Running the fan in winter months can also help remove harmful moisture from your attic reducing the build-up of mold and mildew.

We also have a solar gable fan intended for a smaller space you can check out.

Frequently Asked Questions:

What are the features of the attic fan thermal switch?
The thermal switch automatically turns the fan on when the attic temperature reaches 80 degrees and shuts off when the temperatures reach 65 degrees. It also increases the life of the motor.

Can I install this attic fan on my flat roof?
It is not recommended because you would need to build a curb for it.

How much does it cost to install this attic fan? 
Most installations will cost anywhere from $125-$175. The commercial-grade solar attic fan can be installed by someone with roofing experience in approximately 1 hour.

Will this fan be effective if I already have a ridge vent? 
Yes, our fans use active ventilation to pull heat out of your attic giving a full air exchange about every eight minutes. 

How noisy is this attic fan? 
This attic fan is very quiet. We even put one in our own home and you can barely hear it, even when you are in the attic.

It was simple the only thing hard was carrying it up to the roof.


Great products. I bought the solar attic vent with the remote. Then I noticed that I already have an electric fan in an attic that work great. That is the only reason I am returning the remote. The solar vent work GREAT . Very silent . My house is much cooler. I like the products so much that I am buying some solar for my back yard
