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

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.

Great fan very powerful and solar panel is amazing

If I could I wouldn't even put a star. I bought this for a customers to install for a dog house I built... and just as I was getting ready to load it in my truck I decided to turn on the vent... the vent wouldn't turn on. I called the customer of the problem and said I was going to try to replace it... as my bad luck I missed the return window... so now I'm out of this money spent for nothing and a customer lost all because I didn't deliver. Ahhhh!

Edit: I was able to contact the seller and we found a solution. Thank you.Installed this item and within 3 weeks, one of the four fabs stored working. At 4 weeks, all of the fans are not working. I have a hole cut out of my coop wall for this fan.. it’s not as easy as “uninstall it and send it back for a refund”. Besides that, I’m passed the return window.I’ll try to upload a photo or video later.I did check it before installation and I made sure the solar panel is in a prime spot for sunlight.

Does the job for my chickens

Ordered in February, so box sat for a month until March when I could install unit in greenhouse. Ran for 3 days before completely failing. Appears to be one of products components, not the solar panel or connection. Would not run when cord plugged into a power source via usb cable. The paperwork states they provide after sale service and to contact customer service, yet box and manual provide no phone number or website.Update: The buyer store has contacted me and promised a full refund.

A++++

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.
