I've got my roof fans figured out, but now, I'm working on a design to put 3 - 9inch thermo fans, that will blow the heat out from the sides of my garage, of course these will be powered by solar........and have noticed a lot of solar panels come it 12 volt. I'm trying to figure if i need a 200w or 300w solar panel, and each fan will be wired with a resistor switch which will allow the speed of the fan. Having these fans already in 12 volt, running the wire down into a splitter box, that can split up and run the wires to all 3 thermos. Is there something in the line i should have to help from burn out. Each resistor switch comes with a 30 amp fuse...............any thoughts.
