Hi there,
I have an attic with a large space. I want to install a attic fan in it, to make it properly ventilated, but i this issue I'm facing a problem that I don't know what type of attic fan and also with what rating of the fan should I deal with. Also is
Solar Attic Fan effective in this case. If yes then what is its efficiency, i.e. can i rely on the solar attic fan.
