Review on FISTERS Solar Powered Attic Foldable by Kev Mills

I have this in my greenhouse as an exhaust fan and I plan on adding a second one for extraction. Easy to install but make sure your solar panel is south facing to get the best sunlight at an angle provided by the pre-drilled holes on the frame. That will work. I had a problem with the battery but they replaced it immediately. The battery is designed for a constant fan speed, which extends the life of the fan. It runs about 15 minutes without sun but is not needed at night in my greenhouse as I don't need to cool the greenhouse at night. Honestly, for the fans, this is a pretty decent price, and it's self-sufficient.
