Has anyone had one installed and thought it was worth it?

I've been looking at these too. My only reservation is having to cut a hole in the roof. Seems like a leak waiting to happen.

put one on a gable vent. Don't cut the hole in the roof. Here is the one I installed.

By all means, put it in a gable. And don't necessarily expect to notice how much good they do. The benefits are more of the slow and steady variety. Lower cooling bills, longer lasting roofing materials, reduced chance of attic molds forming. Ridge and soffit vents are a big help, but regardless of whether it's solar-powered or not, a fan that is in regular use will help assure that the job is properly done.

Yes, Sag, the one I show has a built in thermostat, I set on 90F. I just went through the Summer in Phoenix with that and a swamp cooler. A very hot Summer, too. When it was 118F out, it was only 129 in the high part, middle of the attic. I have heard stories of 170F attics in AZ.

Make sure there is a way for fresh air to get in on the other side. Soffit vents are good, but you don't want to only draw air from them, and you don't want to let too much air in because it will get freezing cold--you can get an automatic gable vent for less than 100 bucks more. Maybe one of those geniuses from TJ could help you--but then again, maybe not.

Yes, very important. I recently replaced a gable mounted attic fan in one of my rental houses....gable vents normally have some type of screen on them to keep critters out. It's usually just regular window screen.

While I was up there, I noticed that the screen on the gable vent on the opposite end of the house was completely blocked. Makes sense, I guess...the fan is sucking air through the attic and airbourne stuff outside can get stopped by the "intake" gable vent's screen. It can build up until the vent is completely blocked....rendering the fan pretty useless. I would suggest checking that screen every few years.

I imagine that (working) soffit vents would be less susceptible to clogging...there's so many more of them.

The original question was "has anyone installed a solar attic fan" and is it worth it? My AC guy said I should install a gable fan. My father suggested a solar powered gable fan becaust it wont' cost me anything to run. My dilemma is if I get a solar powered gable fan my AC guy said if it burnts out you are out of more money then a powered fan. Solar powered is zero cost to run but about double the cost to purchase. I haven't found any reviews on solar powered fans. I've had my eye on the honeywell model [url=http://www.amazon.com/Honeywell-527SHON103BLK-12-Watt-Gable-Powered/dp/B005O0TJJE/ref=sr_1_1?s=hi&ie=UTF8&qid=1334253497&sr=1-1]Amazon.com: Honeywell 527SHON103BLK 12-Watt Gable Mount Solar Powered Attic Fan: Home Improvement[/url]

I live in Georgia so the fan is going to running a lot from late March all the way to possibly November.
Does anyone have experience with a solar powered gable fan?

Powered attic fans burn out very easily. They are typically cheapo made electric motors. I went through three fans in 5 years. When I had my roof replaced I had them cut a ridge vent and board up the fan hole.
