Rec`d fan frame a little bent .But bend it back so blades wasn`t rubbing against frame. Also frame edges and fan blades are sharp be careful got cut on finger. Installed in attic what a big difference. House really cooler . Fan is really quite compare to electric unit i replace it with. Thinking about buying another one

I bought this product in 2011, it was easy to install, it is now 2015 and the fan is still working fine. Check out http://www.howtomakethephilosophersstone.com

I put 3 of these in my attic gables on my 1 story house. They definitely cool the attic by at least 20-30 degrees during really hot days and keep the humidity down during the winter. It takes a bit of work to mount them to a board and THEN to your gables, but well worth the effort. I would suggest putting in an inline switch so that they can be individually shut off and controlled in alternate seasons.

I read all the reviews before purchasing this fan. It sounded like the perfect product to circulate air in my 300 sq. ft. Shed. I was even prepared to build a better frame for the solar panel according to other users. Fan came in perfect condition and didn't take too long to install even considering I had to cut out and install gable vents. In addition I trimmed all branches and trees around shed for optimum sunlight.
Once the fan was installed yes the fan immediately started turning.....however it didn't have enough power to blow out a candle let alone blow open the louvers on the vent. I checked on the fan on several occasions and yes sometimes it was spinning faster than others, but never enough to create any air movement. This was a huge let down.

I bought this product to help cool the attic of our home (about 1300 sq ft). I know the product is not made to cool something with that much open space but, I have a plan on purchasing additional hardware (another fan and panel combo and two more panels).

I layed everything out on my porch and connected it up to test the hardware before installing it, literally is was only two wires to plug in. With the panel laying out in the full sun and the fan on my table, it turned right on. It was good to be able to see the fan working. It also gave me the opportunity to check a couple of things:

1. See how much air flow the fan does put out
2. Check for noises,etc

The only time the fan assembly makes noises is when there is not enough power (i.e. not enough direct sun on the solar panel). The noise is noticable, but not overbearing. I have installed my fan assembly on the gable over my bedroom and do not hear the whining noise at all inside the house. I hear it slightly when standing directly underneath of the gable outside, but only barely.

Installation: I made my framing for the fan itself and mounted it before even climbing into the attic. I also installed the mounts onto the solar panel frame. I literally was able to climb on the roof, drill a hole for the cable, mount the solar panel to the roof and caulk the holes in less than a half hour (includes putting up and taking down the ladder and hauling the tools - cordless drill/screwdriver, caulk, screws and solar panel). I also was finished in the attic in under a half hour, I do confess I had my wife climb up with me, hold the fan and mount in place and hand me tools. It was a very easy install and the included nail in mounts to hold the wire, were very helpful.

Cons:

Shipping: The package did show up beat up and I could hear the parts knocking against each other when I slightly shook the package. I thought the solar panel would be broken, but it made it in one piece. The fan assembly, mounts and screw packages were poorly packed for shipping.

Directions: I only have one minor issue with the directions that were sent with the equipment. The directions were obviously for an older model with different mounting points. It was easy to figure it out, but could confuse people.

All in all I am happy with the product, and will be purchasing more soon to more thoroughly cool the attic.
