I believe so yes. I don’t think I’m going to mount it, as I would have to cut polycarbonate and do measurements which I’m terrible at. I’ll probably set it up inside facing the door to move hot air out. We’ll see
You could make any fan solar power. Get a couple 12V deep cycle batteries, a solar panel battery charger kit with correct amperage, 12V to 110v power inverter, and a 110v fan of your choice. Just make sure the inverter you purchase is rated higher then the fan you want to use.
If it moves air it should help, question is how effective it will be but that is not down to the power source. It's just electricity and how it's made is not important.
