The solar attic fan—why do you need it?
Unfortunately, the dark material used on most roofs today absorbs a lot more of the sun’s rays than the wood shingles used in the past century.
A solar powered attic fan ventilates the attic space and dispels the stifling heat. A fan can also create a draft which draws in cool, gentle breezes through the windows below. The hot, stagnant air is swept up into the attic and out through the solar powered fan.
A solar attic fan is also very good at getting rid of excess moisture trapped in your attic. Moisture can cause a variety of problems, from rust and rot to increased bacteria and mold, which can be dangerous to your health. This is why building codes require openings, or vents, in your attic. But these passive vents don’t provide sufficient air flow, so the majority of the time your attic continues to build up heat and moisture.
The solar attic fan is so effective and efficient that newer homes are including them as standard. But it’s really very easy to install a solar fan in an older style home. It’ll save you money and add to the value of your house. After all, electricity isn’t getting any cheaper!
