Hey gang. Don't forget the idea of putting a DC fan on a gable end with
either a vent on the other end, or drawing air up through the

The problem I see is that most brands have a motor rated for much higher
power than the paired solar module. Most manufacturers use the same motor
on, for example, their 10, 15, and 20W fans. Nonetheless, if you size and
locate the fans properly for the attic, you will see a dramatic reduction

Although of course I love all things solar, we actually don't recommend
solar attic fans, for the simple reason that the ones I have seen don't seem

Fellow Wrenches,
I have had several prospects and customers ask about installation of
solar attic fans. One customer had a roof replacement prior to our PV
