Solar powered Attic Fan
I've been thinking about getting a solar-powered attic fan installed. It seems like a good idea, but I can't seem to find any information on whether or not it would actually be helpful. Do any of you have one? Did it make any difference in summer or winter heating/cooling costs? Any feedback?
I'm in the Phoenix area, so I've got plenty of sun, and lots of summer heat to push out of my attic.
