I was especially pleased to find out that you can reverse the cable connections to change the direction that the fan runs. That will be handy when I want to switch from blowing cool air in from the outside to exhausting the inside hot air out. (A built-in toggle switch would have been a nice touch though.) It reacts instantly to the amount of sun exposure on the panel, so fan speed is constantly adjusting on days where the clouds are abundant and moving across the sun. It does run fairly loudly when it's at full speed, but I think that somewhat reflects how powerful it is. The panel is of considerable size but was easy to install on the greenhouse roof. The positioning of the panel is permanent, and you can't adjust the angle, although with a little DIY and the right hardware you could probably mount it for adjustable angle. The materials and construction appear to be very sturdy. Solar power!.....that's 100 watts that won't have to be drawn from my limited electrical supply. Review: Great product but installation should not be as easy as shown in the video. - The panel and fan function as they should. I purchased one with a 100-watt panel. The fan speed is more than sufficient to cool my 400-square-foot garage attic. Be aware that you might find it too noisy depending on the ambient. The extension cord is 16AWG, which seems to be at the borderline capacity. The instruction video shows the easiest but the riskiest way to mount the panel on the roof. To avoid leaks 100%, I used flashing mounts instead of drilling holes in the roof directly. Although it cost me approximately $200 in total for the mounts, conduit, and tools, on top of the product, I am happy that I did not cut corners. Update: The extension cord became hot, and plastic parts at the terminals were blackened. To be safe, I upgraded the cord to 12AWG with MC4 connectors. ## Features - POWERFUL COOLING WITH INCLUDED THERMOSTAT – High-efficiency 100W solar fan with inline thermostat for automatic temperature control.

I did have a question like you and I remember calling the manufacture either by looking it up on the Internet or finding the name and phone number in the packaging. They did call me back and we’re very helpful . It is a small fan and does not put out much air movement . But the solar panel is decent size and powerful I will eventually find another fan to connect to it . **Q: How does the fan turn off and on?** A: Once everything is connected fan and panel. The fan will come on as soon as the sun hits the solar panel. When the sun goes down the fan goes off. It is completely controlled by the sun. **Q: How do I get the free thermostat?** A: If you have purchased this product please send a message to seller through amazon messaging. **Q: Would the panel work mounted inside greenhouse ?** A: Mine is in my wifes green house14X14ft works perfectly full sun full speed cloudy half speed. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just right for my greenhouse *by B***Z on March 7, 2025* Just installed this fan in my greenhouse, and so far it looks like it will be very effective.

Using it as an exhaust fan. Works good why it worked....twice. This fan runs constantly runs during daylight hours except cloudy days. Two times it has quit and when I checked on it, both times the wire connectors had melted, once at the fan, second time at the solar panel outside mount on the roof. It needs a regulator or something. I think to much power is getting to it. This fan runs full blast at full sun. ## Frequently Bought Together - Amtrak Solar 12-Inch 100W Solar Attic Fan Assembled in the USA – Quiet, Waterproof Vent for Attic, Garage, Greenhouse – Plug & Play Cooling with Monocrystalline Panel - Amtrak Solar Thermostat – Made in USA – Automatic 12V Inline Temperature Controller – Plug-and-Play On/Off Switch for Solar Attic Fan, Roof Vent, Gable, Shed, RV or Greenhouse Ventilation - iPower 12-Inch Square Aluminum Automatic Gravity Shutter Louver Vent, Silver --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/36591103-12-inch-100w-solar-attic-fan-with-thermostat-2100-cfm](https://www.desertcart.hr/products/36591103-12-inch-100w-solar-attic-fan-with-thermostat-2100-cfm) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-09*
