5 Inch Solar Powered Fan, Solar Exhaust Intake Fan Kit, IPX7 Waterproof Dual Fans with 13Ft On/Off Switch Cable, Cooling Ventilation for Greenhouse, Chicken Coop, Shed, Dog House, Outside

I liked these fans so much I bought two more of them to run three solar boxes. The two fans allow you to use one to bring air into the box and the other to vent the hot air, cooling off the interior components. Power cords are long enough to allow the panel to be mounted in the best spot to capture the sun. Would buy again if needed.

The product works exactly as advertised; you put the solar panel in the sun (or even in bright light) and it runs the two fans as long as there's light. There's no battery storage, so when there's no light available to the solar panel, the fans stop operating. I knew that, and was fine with it, as I don't need the fans to operate at night. The cords from the solar panel to the fans are more than adequate in length for just about anything. I have my solar panel just propped in a window with a blind behind it holding it in place, and the fans are installed high up at the vents on each end of my 16-foot long storage building. There is no need to do a permanent installation of the fans if you choose not to. They're lightweight. I installed long plastic wire ties around the outer box of the fans, left enough slack at the top to use the wire tie as hangar, and just hung them on cup hooks over the vents. That way they can be easily moved or taken down. I can see a lot of uses for these little fans beside ventilating small sheds, greenhouses, chicken coops and so on. But, a caveat: they are not going to move enough air to bring the temperature down very much, only move air and circulate it. I live in a semi-tropical area of the country, and at the moment it's 90 degrees plus outside, with high humidity. The fans would have to be considerably larger to have a cooling effect in these conditions, but they do move air. I would love to have had the option to up-size the fans to something slightly larger and more powerful, but for this price and the fact that they do work as the manufacturer/seller claims, still not unhappy.

For the price, this little kit works well in my storage shed. I cut some holes for a vent, then put a hole in each side of the vent and attached the fans from this kit using a cable tie. It does have airflow, although not as much as I'd like, it truly depends on how bright the sun is that day. Because there is no battery with this kit, the fans only work when the sun is shining. The brighter the sun, the stronger the airflow. If you're looking for a fan that will blow even in dusk, this may not be the best choice. But if you need a simple kit that helps move air in/out on a hot day, this is great for that. Overall I'm happy with it. Easy to install. I didn't like the parts that came with it to mount the solar panel, but I used my own screws and washers and it was fine. For the price, it's good.

These work well. When the sun hits the panel they take off fast. It's a good option for powered exhaust at least in the sun

Great product and the fans work well during the day! I didn’t realize there is no battery system, so as soon as the sun goes down they turn off. That’s a pain in hot Houston and I wish they still worked in the evenings. However, they installed nicely into the hole I cut in my coop and the noise is low.

My thoughts on this fan setup have gone up and down. Seems well made for the price. When I first tried in late on a cloudy day the fans wouldn’t turn at all. Put it in the window for the morning sun and still nothing. Was about to return it but decided to give it one more try outside in fairly bright sun and it worked great. I guess the window filtered the sun’s rays. Anyway, it now works at least partially even on a cloudy day here in the Northwest.

The solar works great but when both are one I hardly feel airflow

I installed this in a metal shed and it helped to reduce the heat significantly. Great value for the cost and size. Runs most of the day. Although I do wish it had some sort of batteries to keep charged throughout the day/night.
