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 1,100 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.

Returns Made Simple

We flat out hate returning an item to a store, don't you?

First, we try and avoid this by only carrying the best solar lights we can get our hands on, but if for any reason the light doesn't fit your needs, we are going to make this as simple as possible.

If you are dissatisfied with your order for any reason, you can return your items within 30 days of product delivery. So you get three weeks to try the light out and ensure it fits your needs.

All returns must be in original product boxes, including all parts, packing materials and manuals. Products that have been damaged by customer or modified, may not be returned.

Refunds for items returned will be credited in the same form as the original payment type. 

Non-Defective returns will be subject to a 10% restock fee. Solar Christmas lights are also non-returnable after December 20th for orders in that calendar year.

Orders that have current active warranty claims are not eligible for return. Customized products are also not eligible for returns. 

Shipping costs are non-refundable.
