Solar Powered Exhaust fan, 20W Solar Panel + 8" Ventilation Vent Fan for Outside Greenhouse, Chicken Coop, Shed, Pet House

Works perfectly. Not noisy. Solar turns on when the is out and it's needed. Turns off with no sun and isn't hot. Easy to install. Perfect for my greenhouse.

Only works during the day, using it to keep out moisture in a metal storage container.Excellent function

made well works good

The blade stops after 1 year. Says it’s 25 watts but the description reads 20 watts??? Cheaply made. I ll try another brand

Love this!.. Keeps the chickens well vented

I bought two of these fans to help keep my greenhouse cool on hot days.Installation was straightforward and easy as this is not my first foray into solar products and the connecting cables were long enough that I could position the solar panels to where they get full exposure to sun. I was initially impressed at how much air they move and was pleasantly surprised by it! Lowered my greenhouse temps 15 to 20 degrees at peak afternoon.Installation was done on a Monday afternoon. By that same Thursday, one had stopped working and this morning (Friday) I was frustrated to see that the second had stopped working as well. Good installation, perfect panel placement, worked for less than four days. If I “assist” the fan blades to start spinning when the panel is in full Sun they will work briefly before stopping again. Leads me to believe there is a problem with the fan motors.Hopefully I just got some from a bad batch and the manufacturer will send replacements but as of now I cannot recommend these to anyone.

You know, you can find tons of these on Amazon. Difficult to figure out which ones are good and which ones are not. I like how this had the little shutters that opened up when the fan was running. I put this on my shed because it was getting so darn hot in there in the summer that I think it was starting to affect the things that I had in the shed. I can say without a doubt that it is really not the heat down considerably in there with this thing on. And the sun is hitting that solar panel that fan is really moving fast and the shutters are completely open. I wish I had done this years ago. I'm glad I did it. It was very easy to install by cutting a hole for the fan to go in and I just caulked around it to seal it up. I recommend!

I bought 2 of these for our chicken coop. I wasn't sure what to expect because the materials looked cheap, but once you get the solar panel in full sun these little fans work better than expected.I did have to contact the seller because we needed some power cord extensions and he responded pretty quickly. He was able to direct us right to a link so we could install these fans to get them working!
