A solar-powered roof vent sits on the top of your house and vents your attic air, and it is powered completely by the sun. It doesn’t add to your energy bill, and it doesn’t contribute to climate change. In fact, because your house is cooler in the summer, you’ll be using less energy. A solar-powered roof vent also reduces moisture build up and extends the life of your shingles.
Many manufacturers now offer solar powered vents to ventilate attics and help keep attics cooler. Solar powered vents offer an environmentally friendly and economical solution to summer time cooling problems resulting from attic heat penetrating your home’s insulation. During the summer, attic temperatures can soar to over 150°F, keeping your attic hot throughout the day and well into the night. With these high temperatures, your attic insulation will become less effective in stopping heat from entering your home. Installation of a solar powered vent on your home minimizes the amount of heat entering through the attic by reducing your attic temperature. By minimizing the amount heat entering your home, you will save money on your summer cooling bill and make your house feel more comfortable.
A roof-mounted solar attic fan transforms sunlight into electric power to drive a motor that spins a fan blade and removes heat and moisture from the attic. Solar powered fans rely on a small (typically 10 or 20 watt) solar panel to power a DC motor when the sun is shining. The fans, which exhaust air at a rate of 800 to 1200 cfm, are installed with intake vents (such as soffit and gable vents) to provide high-capacity powered ventilation without electric operating costs. Most vents are mounted high on the roof, near the ridge, and combined with soffit or gable vents for balanced intake and exhaust air streams.
The solar vent operates without fuel, waste or pollution. And as a totally solar-powered solution, it’s also environmentally friendly. There’s no need for electrical hook-up or electricity, simplifying the installation process.
A solar-powered roof vent or attic fan sits on the top of your house and vents your attic air, and it is powered completely by the sun. It doesn’t add to your energy bill, and it doesn’t contribute to climate change. In fact, because your house is cooler in the summer, you’ll be using less energy. A solar-powered roof vent also reduces moisture build up, prevents ice dams from forming in the winter and extends the life of your shingles. Not only will this nifty gizmo lower your utility bill, it will protect the quality of your home.
