ECO-WORTHY20W Solar Powered Dual Metal Shell Exhaust Fan Kit Waterproof and Plug & Play for Chicken Coops, Greenhouses, Sheds, Pet Houses, and Windows

I purchased these for my chicken coop and they create a nice breeze. I ended up getting another set

Small dual fan that is much smaller than it looks in the pictures. Gonna try to use it, but, my advice is go bigger. Between $100 and $200 range. 50 watts or more.

This little fan does exactly what it says it will. The speed is much lower with cloud coverage but at least at the hotter points of the day my coop has more ventilation.I will be I stalling a solar vent on the other side this weekend that has a large battery that holds the excess charge so the exhaust fan can run overnight but also has a switch to turn it off.This little guy only runs great with the sun full blast but because it slows down with cloud cover it does t pull out as much air as I would like it to. It needs a battery back up (in line that charges with the sun) so it can stay more steady vs high and low speed

The media could not be loaded. I had just received/installed this fan today but had to write a review. Just… WOW!! I was blown away (yeah, I just typed that, lol), by the performance of this dual fan!When I was looking for a coop fan, I was needing something that would fit perfectly over the rear coop door. With a little modification (I had to carefully remove the plastic “window” on the bottom area of the door), I was able to install the fan in just a few minutes. Once installed, I had placed the 2 solar panels high on the privacy fence behind my chicken run. Once in the sun, the fan blades took off and I was amazed at the airflow in the coop!There is one thing that I’ll mention (and it deserves to be mentioned), there is a hum that comes from the fan case when the panels are not receiving solar energy. It’s a tad annoying, but doesn’t appear to bother my chickens. Simple solution… just disconnect the cables at night and reconnect them in the morning. Overall, the quality of the fan, case, solar panels, and cables… excellent!! I highly recommend this fan for coops and I’m sure that it works great for greenhouses, as well!

Nice quality mounting and nice units, but they barely move any air.

Great item, price, and delivery time. Thanks

When it goes dark it is fine but in the morning as the sun is coming up it lets out a definitely annoying humming sound, I have to plug it in and unplug it to stop annoying my pigeons. Works fine but that humming sound beyond irritating

This fan works great. It's easy to install. It features two exhaust fans and metal components, all of which are well-made. It works great for a lot of things like pet houses, sheds, green houses, chicken coops and more. I use it in my shed and I love that it's solar powered.
