Solar Exhaust Fans & Powered Fan with 15W Panel & 2-Pack High-Speed Brushless DC Fans,Solar Ventilation Fan for Greenhouses, Chicken Coops, Attics, Barns, Sheds & Dog Houses

Fan won't work at all in the shade, but when the sun is out it circulates the air pretty well.Don't expect enough air to keep you cool on a hot day. Think of it more like a desktop computer fan. It's enough to circulate the air, but that's about it.I mounted the solar panel on in top of my shed. The mounting bracket is functional but will likely bend during the next tornado warning storm. If the area you live in has mild weather it might hold up. Many similar fans don't include a mounting bracket, so it's hard to complain.It's nice to have a switch that allows you to turn it on and off, because you don't want it blowing in cold outside air during the winter.Don't expect much, it's more like a small attic fan, it's not going to move a ton of air. But it does work ok. I just wanted something for my shed that circulated the hot humid air during the summer. It's better than nothing.*EDIT* I've had this unit up and running for a few months in a very hot and humid shed and it seems to keep the shed a good dealer cooler than it was before having the fan. I leave it in the ON position all the time, so when the sun is out, it's blowing air inside the shed.

It works great. The cable is long enough . Great buy

Tested in full sunlight and it worked. So installed it and nothing. Still in full direct sunlight, nothing. Went up and turned the switch off and then back on, then it worked. Next day, no power again. Same thing where you have to turn it off and on for it to work. How are you going to ventilate a building if you have to go power cycle it every day and probably several times a day if it gets cloudy. Worthless.

Works decent. Does not store energy. Only works during day when sun is actually out. Some of the fans wont run at all when day is overcast ( not enough energy)Prolly need a heavier duty one for my purposes.

Well, it's cheap, so to my mind I go in thinking if this works for 3 years, I won. We use it to vent our attic in the extremely hot months (think lower Georgia, near the coast, often highs of 98 or more).Works well, but this house is small, and the roof is not that steep, plus some shade. I'd say if Im lucky it averages moving maybe 1/2 the attic air out an hour, but it's enough to keep it more like 110 instead of 128 up there, on a 96 degree day.My bills dropped about 30 percent from summer 23 to last summer, but I made other changes at that time, including added a window inverter unit.Still, you can tell just from standing in a chair and feeling the ceiling and holding your hand up there in late afternoon, it's a good bit better. Especially the pull-down door area.Actually nice it works best when sun is out, which is usually when it's the hottest, and saves wear on itself as the sun sets so it might last longer, Starting season 2. Used it maybe 5 months, a tad more, last season.

Sunshine Powered Cooling, Limited by CloudsThis solar fan is a great eco-friendly option for keeping cool in direct sunlight. It runs quietly when the sun is out and effectively generates a refreshing breeze. However, it's important to remember that cloud cover significantly impacts its performance. Even a thin layer of clouds can reduce its effectiveness, and complete overcast skies will shut it down entirely.Winter ConsiderationsIf you plan to use this solar fan year-round, keep in mind its dependence on sunlight. While it might not function on cloudy days, some sunlight can still reach the panel depending on your location. This might offer some limited functionality during winter.OverallThis solar fan is a good choice for sunny environments and those seeking an eco-friendly way to cool down. It's quiet and effective in direct sunlight. However, for areas with frequent cloud cover or those needing consistent cooling year-round, a different option might be more suitable.

The media could not be loaded. I had a positive initial impression, but the lack of a battery backup was a deal-breaker for me. The fan was packed amazingly and easy to assemble. The solar panel worked well, pushing out immaculate air when it received sunlight. However, even just a tiny bit of shade triggered the fan to shut off completely. Unfortunately, I realized that the fan didn’t have a battery backup. Since my chicken coop area experiences shade throughout the day, the fan couldn’t run continuously, which led to my decision to return it. Despite the positive aspects, the lack of a battery backup made it unsuitable for our specific needs. I’m now planning to purchase one with a battery backup.

Even with direct full sun all 4 fans sometimes won't start. You have to manually spin the blades to get them ro run. When all 4 fans are running it does OK. Suitable for a small area.
