Question on Solar Attic Fan
I've clipped an ad for a solar powered attic exhaust fan.
They quote a price of $485 installed for one fan. Before I contact the advertiser, can anyone tell me pros and cons of this item and if the price seems reasonable. Also, how many fans would one need per cubic foot of attic space?
We have a vast roof on a N-S oriented house. I am hoping the day will come when affordable solar power will be here!
