5.0 out of 5 stars Perfect Solution for My Coop
Reviewed in the United States on June 11, 2024
I was looking for a fan to install in my chicken coop. There are lots of different routes to go and lots of different fan options. This product is a great overall solution-it is easy to set up and install, it has a battery, and it works. It checked all of the boxes. I'm glad I went with this product over others. It is plug'n'play.
My chickens love it and now just sit in front of the fan all day.

My only complaint is that if the battery fully drains, the fan does not automatically turn back on. You have to manually push the on button after the battery drains and is recharged--it won't know to turn itself back on when it gets re-charged. Not a big deal though.

Impressive kit. Comes complete with plenty of electrical wire, and all the connectors. Well, thought out. It is a little more money than others I've seen on here, but we are so happy and amazed with the ease of assembly,performance, fan size and quality. Assembly was done in about an hour, most of it deciding placement. You will likely need a handheld drill and screwdriver. We currently feel it works best without the battery back up hooked up-but it's spring going in to summer and there is plenty of sun. The panels are very sensitive to the sunlight and work even on overcast days. The greenhouse we placed them on is 10x12x12 tall. The fans are mounted to the end wall at about 10 ft. The solar panels wing out at the Frame above the door at the apex of the poly tunnel frame. One fan is on each side of the top of door frame. There is a window on the opposite wall. We added a 30% sunshade (purchased from Amazon also) on our Northside because the afternoon sun was cooking our plants. These fans are an integral part of humidity and temp management. So far they have been powerful enough-as noted by the leaves of the plants gently dancing. They work consistently noted by temp, and they pick up speed more sun. Thinking about some for our house now since we are off grid.

Reviewed in the United States on May 4, 2024
please notify the solar panel manufacturer that the sticky gum they are using to stick the connector box to the back of the panel is not strong enough to hold the box on. in the process of trying to position the panel it came loose and one of the "tabbing wires" broke. luckily a friend of mine was able to fix it. However I would imagine that this will be a chronic problem. they need to gorilla tape it down or some other method than what looks like a wad of chewing gum. PS it would be nice if the light that shows that the solar panel is charging the battery would be on even when the fan is not! Have you considered making a product that would fit in a window of a persons home?

5.0 out of 5 stars Had an issue, replacement works great
Reviewed in the United States on May 21, 2024
I had an issue with it shutting off even though battery was full. The company stepped in and went above and beyond to make things right. Will install the new one and update in a few days to see if problem resolved. I really hope so as I love the idea of the product and need it working.
Update, this replacement is working as I hoped! Resumes working as soon as the sun hits the panel.

This is absolutely Fabulous. Not only solar powered but has a batter for continuous usage after the sun goes down. Performance is fabulous. Super easy to install. Fan noise is very minimal. The speed of the fan is perfect. It’s a great value for the money.

Reviewed in the United States on June 19, 2024
I ordered this for my chicken coop. My coop is 8x12' and this fan did NOTHING to move air.. the only thing this flimsy piece of plastic is good for is NOTHING.

Seriously. Do not waste your time with this. The WHOLE thing is flimsy, thin, cheap plastic.. this thing is an insult to anyone's money. I searched for hours and went with this one because the descent reviews for coop use. Don't get deceived as I did... I'm a real person with a very real need to cool the coop for my girls, and this fan was an absolute waste of my time to deal with.

5.0 out of 5 stars Solar fan with battery backup
Reviewed in the United States on May 1, 2024
The fan was packaged very well, included instructions, and quick and easy to assemble. It started to work as soon as the solar panel was exposed to the sun. My husband installed it in a chicken coop we were building. It helps with the heat and humidity (although our temps are mild at the moment we hope that it helps as the temps reach 90-100 with high humidity). It works on solar while storing solar power and will switch to battery when needed. It is very quiet. So far I am very happy with the fan. I feel it is reasonably priced as well.
