Asks Marcus: I want to put in a roof fan, but I am not satisfied with bringing electricity to it. Do you think the solar powered fans are good?

Danny Lipford: Solar powered exhaust fans have come a long way since they were introduced a few years ago, and attic ventilation is so important as it can get very hot in any attic space. Now the solar powered exhaust fans are great because all you have to do is cut a hole, fit them, and don’t even have to worry about calling the electrician to power an electric motor.

However, it is crucial that you determine the correct size. The first thing you need to do is measure the square footage of your attic. Point seven shows you how many cubic feet per minute it will take to properly ventilate your attic. Now you may be able to do this with a solar powered exhaust fan, but it may take more than that.

Also very importantly, make sure you have the right intake air. So check your reveal areas around your overhang to make sure there is enough air getting into the attic.
