Solar Powered Attic Fans

There are alot of applications for a solar fan that are still gaining the consumer's confidence. One product that can easily be a applied today is the solar attic fans. I read alot of posts asking: "Does the solar powered attic fan really work?" The answer is yes. While it may not have the exact power ratings that a wired fan would have, there are three main reasons to use a solar powered fan.
The first reason is easy, which is, if you believe in solar power and its benefits to our earth then this is a nice application. The second, would be cost, which isnt the same benefits as a solar panel on a residential home, it still has its merits over time. And finally, the reason I would think most people should look at it is the lack of wiring that takes place on a solar exhaust fan's installation. Most products require no wiring, making it much easier to install than hiring an electrician to run wires to a remote place in your attic.

I will highlight three of the solar powered attic fans out of the many on the market as the ones to review. They have a sturdy design, solid installation diagrams and have the power to do that job. Speaking of power, most people have said that the fan can do 75% - 90% of the wired attic fan's job, which for its purpose is still very adequate.

The first fan is model number SAF10, no wiring necessary and has a 25 year warranty. It is not intended for a flat roof nor can be installed on a side mounted roof wall. I would advise you to purchase the thermostat as well. This is my top selection because it also can be purchased with a thermostat, which I think is very much needed.



The second fan is essentially the same product, in a metal case but also incorporates the use of the wind for the turbine ventilator. This is model number ASF-12-C2.


The last solar fan is model number 53510 and and is rated at 1200sq ft. I have selected these three fans, because they are all top models, but they are also very similar in design.



I had previously done a review on 2 Portable Solar Fan in a previous post for things such as boats, rv's or sheds. Thoughts or comments?
