Rated 4.0 out of 5 by 8 reviewers.
Rated 1.0 out of 5.0 by Just not there. First off the enclosure itself had issues. While mounting the solar panel on top of the fan two of the bolts that are used to mount the solar panel became loose and just spin so that the solar panel cannot be secured all the way down unless removed and drilled straight to the roof. For this much I should be able to mount it the way I want to. The house is 1500 sq ft so should have sufficent power to help and I bought the controlled also. Attic stays at about 145 degrees and remains that way till about 2 in the am when it drops to around 120 degrees. Sounded like a great idea but haven't seen the return on investment yet.

Rated 5.0 out of 5.0 by Best Purchase I have made for the roof I replaced one whirlybird which was not correctly installed by the contractor, with only one installed I can feel the difference inside the house here in Southern California. I will be installing another one within the next few weeks, prior to summer. Excellent product... June 8, 2015
Rated 1.0 out of 5.0 by Not right for me. The fan doesn't turn very well and at a slow speed. Would turn off and on when it was in full sun. August 16, 2014
Rated 5.0 out of 5.0 by A well designed, well made ( in the USA) roof fan. The fan was easy to install and performs as promised. I was disappointed that Home Depot sold the fan but not the SC-20 controller which adds full functionality by running after sunset, I had to purchase it directly from the manufacturer, Homer, are you listening?

Rated 5.0 out of 5.0 by Attic Fan Exceeded Expectations!!! This Attic Fan is 3X more powerful than one I installed 2 years ago. It pulls so much hot air out of my attic I barely run my air conditioner any more. Amazing! Only one complaint...Apparently Home Depot does not sell the controller for this model. It is not necessary, but I have one on my other unit and it is fun to play with. HD should sell them together. November 4, 2014
Rated 5.0 out of 5.0 by works as promised!! This attic fan, US Sunlight 9930TR 30Watt cooled the attic immediately. It was easy to install and works as promised. Buy the controller with it 59.99, it will help a huge amount in the hot evening hours. May 20, 2014
Rated 5.0 out of 5.0 by Series 30-Watt solar panel with heavy duty ABS fan The product arrived quickly, packaging in great condition. It was installed by the people putting on a new roof and seemed to be an easy installation. Since then it has been working well. Very pleased with the product. Thank You Your requirement for a 4 letter nickname is difficult since mine happens to have only 3 letters! To comply with this requirement I've added a letter!!!!! May 13, 2014
Rated 5.0 out of 5.0 by Very happy Powerful motor for a solar product. Easy installation. Great price compared to other comparable fans! March 25, 2014
