Very easy to work with.

This fan will only move the advertised air volume under IDEAL conditions -- summer, high noon, no obstructions, properly positioned solar panel.

I installed this fan to cool a garage that gets sun all day and gets pretty hot.

The instructions that came with this product could have been a little more detailed. When I received the product I set it up to make sure it worked before I installed it in the attic. I put it together and nothing happened. First I thought that the solar panel had to build up enough power to energize the motor. Then upon looking closer at the fan I noticed something that looked like a controller on the wire line before the motor. Wanting more information I went to Honeywell's website and researched the product. The thing that looking like a controller is really a thermostat. It turns on the fan when the temp hits 85 and shuts it off when the temp goes down to 65. I would have liked to see that information in the instruction manual.

Other than it was an easy read to figure out how to install. I like the long cord that it comes with, it allows me to have optimal positioning of the solar panel on my roof. I will see how it survives the summer. If it works well I will buy another and put it on the other side of the house. Though if the price drops down any more I will buy it sooner.

It was not too hard to install. Instructions were helpful, though I would have liked guidance on ideal angle and direction placement of the solar panel. The obvious is most directly toward the sun. It is overcast today and it is not running at noon. Others claim it runs when overcast, so maybe I don't have the ideal angle. I have it facing on an angle toward the sun. Clear days it works beginning mid morning and on into the afternoon. I thought it would move more air. I think I will have to purchase a second to move the amount of air needed to bring the temp down in the attic area. It runs quietly and I like the idea of not installing power or paying more for electricity to ventilate my attic.

I did research based on customer reviews. That is why I chose this unit. Price and reviews indicated it was a good choice. Would I recommend it; not unless I can get more air flow from it.

Actually, I'm not using it as an attic fan, but as a ventilation system for my (Aluminium exterior) shed in Florida. Impressive result!

The only little irritant in all this is that upon opening the package, it was evident that the box had been opened and unpacked previously. Fortunately, there were no missing parts, but the hardware was loose all over the box and the bag that once held them was torn open and half empty.

I ordered 2 of these in seperate months so I could see the quality before investing too much.
I received my first one & was very impressed with the set up, quality of the product & the ease of installation.

I would give it a 5 Star review but the small connectors from the solar panel to the fan could use a redesign.
The first one plugged in flawlessly & started working right away.
On my second unit the aluminum "bullet" electrical connectors in the plastic housing did not want to make a proper connection.
After fussing with it for 20 minutes, I had to cut off the connectors & use wire nuts to connect them.

It was frustrating at the time.
Overall the items are great IMO & have notice a huge difference in our house staying cool longer & our A/C not running as much.
Especially since we had 10 straight days of 100+ degree temps in STL the last 2 weeks.

I purchased this fan for use in a Solar lumber kiln I am playing around with and it is the first "solar powered" item I have worked with so I was real surprised when it started right up when I plugged it in (was late afternoon). Instructions are good and install was real simple. Fan speed slows significantly when partial shadow on the panel but I hear that's normal. Box I received it in had definitely been opened and hardware for install was loose in box but everything else was in top shape.

The fan installs easy enough but the sun has to be shinning directly on the solar panel. Even the slightest overcast prevents it from producing enough voltage to turn the fan motor

First of all, I haven't installed the fan yet. But I've played around with it enough to have some useful info.

1. Temper your expectations. This fan will only move the advertised air volume under IDEAL conditions -- summer, high noon, no obstructions, properly positioned solar panel. The instructions state that 1 fan can ventilate 1250sqft of a HIGH slope roof. For a LOW slope roof (like mine) I'd need 3 fans to cover that space!

2. Did some solar panel testing. The panel is rated at 20.3V and 0.74A with a max output of 12W. I tested it on a partly cloudy, late morning in mid-April in NJ. The panel was facing the sun at a ~30deg angle. Under cloudy conditions it rated at 19.3V and .3A, which turned the fan but yielded little air flow. Under full sun, it jumped to 20.2V and .7A (full power) and produced decent air flow. I expect it to run consistently at max power on Summer days. Make sure to mount the panel so that there are no shadows or obstructions during the afternoon. And don't expect it to run well on overcast days.

3. I bought this fan for ventilate a 600sq.ft. attic. It had to quiet since it'll be mounted above the bedroom. I think this fan will fit the bill perfectly. I would not buy this fan to ventilate larger space or if noise wasn't a factor since a conventional fan will move a lot more air.

4. Will pay for itself. This fan cost 1.5-2x of what a basic conventional fan would cost. Given that it will run ~10 hours on most Summer days, the price difference will be nullified in just 3 months! The fan will completely pay for itself in under 2 seasons. A conventional fan uses ~350W and I pay 15c per kW for a total of $15/month.

A few other things I found good: The brackets on the fan are designed to ease installation.
