20 Watt Solar-Powered Attic Fan

Our 20 watt solar attic fan by U.S. Solar 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 2,400 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. For more information on the benefits of solar attic fans, click here.

All attic fans now include a free thermal switch!

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 reaches 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.

Does this solar attic fan have a battery backup?
No, all solar attic fans on the market today are powered by the solar panel directly to the motor. For additional run time, consider the solar attic fan controller, which turns the solar attic fan into a fan that can also use house power as a backup source.

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.

Good Fan for Good Price

I find this to be an excellent product. Pros: ease of use, it is fairly light, it is much less expensive than others that i have seen. I found this product to be easy to install. I have been looking at different products for a commercial grade solar attic fan that would be the most suitable for my particular need. After comparing many different ones, both for function and price, I recently purchased this fan. I have not yet received a utility bill so I am not sure yet of the savings I will enjoy. To date, though, the fan is functioning as promised.

My attic fan works, but didn't shut down once the sun went down, and if I wasn't home would run all night. I bought this because the price wasn't too bad. I am very happy with it. It works consistently, and I measured the temperature in my attic and the fan runs things well. If you have a steep roof, I would suggest hiring a professional. But the fan itself works very well.

This is a solid fan. We've had ours running for over a year and it is very quiet, sometimes it's difficult to know when it's running but every time I check it (which isn't that often) it's running like a champ. I can feel the air being pushed out when I'm on the roof. Also, it's been through a full year's weather and the black has not faded.
