PV Fan Uses Sun’s Heat To Keep You Cool

I spent many years in the Southeastern U.S., where the combination of summer heat plus never-ending humidity made air conditioning (or at least a room full of fans) a life and death necessity. Moving out to the arid West, it was a shock that almost no houses have air conditioning. With far less humidity, most homes have whole-house fan systems that keep the air moving, and indoor temperatures tolerable.

But these circulation systems still require a decent amount of energy, meaning that summertime power bills can be pricey. Solatube International, a company known for its passive daylighting systems, recently introduced a line of solar-powered attic fans that could help keep both the temperature and your utility bills from climbing too high.

Part of the Solar Star family of products, the solar attic fan comes fully assembled and can be installed in around 30 minutes, since there’s no need for any electrical wiring. Available in a range of sizes designed to fit all types of roofs, the solar fan is mounted on any rooftop vent. Using energy generated by the fully integrated photovoltaic panel, the fan draws hot air and moisture out of the attic and discharges it to the exterior, providing an even, continuous flow of air.

By providing better circulation, without increasing home energy costs, the fan can help homeowners enjoy more comfortable indoor temperatures, reduce mold-growing moisture, and prevent ice buildup during winter months.

As an added incentive, you might be eligible for a 30 percent tax credit (up to $1,500) on the purchase and installation of all Solar Star Attic Fans. Retail price quotes are available through Solatube dealers.
