This is the kit to get for solar fans - with a back up battery
Top reviews from the United States

- Reviewed in the United States on April 11, 2025Style: Solar 3 fan kit with battery backupVerified PurchaseCame packaged nicely and works very good moving air through my shed!
- Reviewed in the United States on March 5, 2025Style: Solar 2 fan kit with battery backupAmazon Vine Customer Review of Free Product( What's this? )This review is for a Fanspex 50W Solar Panel 2 Fan Kit with 66.6 Wh Battery Backup.
I was very pleased with the package as it was delivered. However, it would have been better with ONE 50w panel, rather than two 25w PV panels.
I put each panel out on a cloudless March West Texas day, at 67*F. They were oriented approx. 30* off vertical to get the best irradiance. One 25w panel output 20w which was excellent, the other panel put out 18w, as tested with an Elejoy EY800W PV multitester. This was surprisingly good, since I was expecting something in the mid-teens.
The battery says it will power the two fans for approx 5 hrs. when fully charged. I got about 4.25 hrs. You might want to consider a larger battery for longer ventilation. There is no indicator for battery charge status, but it would not be hard to wire a small battery state monitor into the system. The two fans are relatively quiet, and are either ON or OFF. I have not tried to put a speed controller or switch on the fans yet. They move a surprisingly large amount of air for their size.
I admit that this is NOT for a chicken coop, but for a workshed that gets pretty warm when the sun shines. I already have one FANSPEX solar dual fan assembly aimed toward the interior roof. This unit was installed near the floor, with a 1/8in hardware cloth cover on it to suck in cooler ground level air in the mornings. It works very well for that. (The hardware cloth is to prevent unwanted crawling visitors.)
This is a great package for multiple uses, and if you have a need for a small ventilation system for a small space, I’d recommend this.
- Reviewed in the United States on March 22, 2025Style: Solar 2 fan kit with battery backupAmazon Vine Customer Review of Free Product( What's this? )The Solar 2 Fan Kit with 66.6 Wh Battery Backup and 50W Solar Panel offers a robust, eco-conscious ventilation solution for chicken coops, greenhouses, and sheds. Featuring two 25W solar panels, it drives dual weatherproof fans that deliver up to 360 CFM of airflow at 3500 RPM, keeping spaces well-ventilated and comfortable. The 66.6 Wh rechargeable battery stores energy efficiently, providing consistent operation during nighttime or cloudy conditions—a major plus for reliability. With an IP67 rating, the kit endures harsh weather, from rain to snow, and functions in temperatures ranging from -13°F to 140°F. Installation is simple with a 26.2-foot cord and mounting hardware, though some users might need extra tools for complex setups. Fan performance peaks in direct sunlight, tapering off in low light, but the battery ensures steady airflow. This kit blends power, durability, and versatility, making it an outstanding choice for anyone seeking a solar-powered, off-grid ventilation system for small to medium outdoor structures.
- Reviewed in the United States on March 1, 2025Style: Solar 2 fan kit with battery backupAmazon Vine Customer Review of Free Product( What's this? )Nice little dual fan, dual solar panel exhaust system. The unit even has a battery pack that you can charge up via the solar connection and it will run the fan after the sun sets.
The fans aren't super powerful, but they move the air. The solar panels are good quality and I laid them out in my shop when I first unpacked it. Hooked the cords to the battery pack and then hooked the battery pack to the fans. Simple process and had everything ready in a couple minutes. I have a few clear panels on my barn roof for light to come into the building and it was enough to start the unit charging. The battery pack has and indicator and it was about 75 % charged on arrival.
The cord from the battery pack to the fans has a switch on it and the battery pack is also switched so you can turn everything off in both places. I was expecting the unit to push air, but being an exhaust fan it pulls it through the two fans and out the side with the finished surface. Hope that makes sense.
Overall, nice build quality on the panels, battery pack and the fans. The wires are light weight but appear sufficient. Does not blast air, but moves it and would keep the air circulating in a dog house, chicken coop or small building as advertised.
I like it and will get a lot of use out of it I believe. Neat little rig if you have an outbuilding that doesn't have electricity but needs an exhaust fan.
- Reviewed in the United States on March 20, 2025Style: Solar 3 fan kit with battery backupAmazon Vine Customer Review of Free Product( What's this? )I've got two 25 watt solar fans - and I like them. They work in the sun - the most important time of day - and gets the air moving. The other units are 25 watt solar panels per 3 fans, this kit is 2 25 watt panels and a battery in the middle. It runs faster with two solar panels and with the battery, it can run late into the night as well. With two solar panels, I can aim them differently to get the most amount of solar power. You can turn it all off at the battery or at the fan on the cord.
Overall: This is the kit to get if you need a great amount of air flow, multiple panels to draw power from and a battery to help on cloudy day or after dark

- Reviewed in the United States on April 21, 2025Style: Solar 3 fan kit with battery backupVerified PurchaseOrdered two of these fans with prime because I needed them quick. They were set to be delivered a few days later. Delivery date came and I received a folding shopping cart instead. Contacted Amazon and they sent out a “replacement” took a week to come in this time. Finally get them and they do not work like they are suppose to. Should run on solar during the day and battery back up at night and it’s not. It’s running on battery during the day then dying by night time. Will never order these or from this company again
- Reviewed in the United States on March 13, 2025Style: Solar 2 fan kit with battery backupAmazon Vine Customer Review of Free Product( What's this? )We have a Costco plastic shed, which is nice, but during summer, sun will heat it up like crazy. In a way that we can't leave any liquid, battery, chemical, etc inside,
This fan 2 fans solar kit is perfect. Easy to install, you dont need to run cables from anywhere. On top of that, since it has a battery "buffer" you can run it even if there is no sun at that moment. My shed has a lot of sun (that causes the issue with heat too..) I ran it around 2 hours without sun, and kept running. And just a couple of hours next day the battery will topped of.
I did added insulation around the battery, since winter is hard here and Lithium batteries shouldn't be charger bellow 32F.
