I have two computer fans in the wall near the ceiling run by a solar panel.
No battery so if the Sun shines the fans work.
So far it seems to do a good job... it is a unpainted garden shed lined with pine.. there is a hole in the floor (around the pier) and the lot stands on cement which seems to retain coolness because its under the shed..I think so far it is working well but have not taken temp readings..but it seems cooler when I first open it than after standing in there with the door open..
