Amtrak Solar’s Powerful 40-Watt Solar Attic Fan Quietly Cools and ventilates Your House Garage or RV and Protects Against Moisture Build-up

I installed this on a 20' shipping container by cutting a hole in the upper part of one door. Mounted the panel on the roof with spacers on one end to create a slight tilt. Cut an air intake in the back at the bottom to pull in the coolest possible air. It made a noticeable difference, but I haven't measured the difference in temps wit and without the fan. Worked from the get go. Needs full sunlight to get good airflow, but that is when it needs to work! My package was missing the 15' extension cord, but I sent a message and was contacted quickly and was sent the cord. So good customer support.

Product is high quality and works very well. Easy setup as well. Video posted didn’t capture true fan speed. This fan is moving fast and producing a large air flow.

I installed this fan I our new greenhouse to use for ventilation. It was easy to install as I cut a hole in a piece of plywood I had pre installed as we were putting the greenhouse up. I also built a stand outside to install the solar panel at a 54 degree angle facing southwest as to get the best afternoon sunlight in our area. As soon as I plugged the fan to the solar panel it went to work. I will have to get a battery backup as cloudy days it will not work. As small thin clouds covered the sun it slowed way down and thicker clouds it stopped. It does pull a lot of air at full speed.

This fan works great. Used in my two car garage. Installed at peak vent. Lowered my garage temp 10° to 15°

I have two of these, both the 100 Watt and the 50 Watt. Both do what I want. The 50 Watt just won't run the fan at Max speed while the 100 Watt will.
