An attic fan will blow the hot air out of your attic, drawing cooler outdoor in through the attic's soffits, or openings near its base. And the best choice in attic fans is a solar powered attic fan - it will do the work of a powered fan without costing you a cent in electricity costs while reducing your air conditioning costs. You will save wear and tear on your air conditioning and make your house more comfortable.
In the winter your solar power attic fan will provide you with a dryer attic as it blows out moist air that accumulates from household water use. Mold and mildew growth in the attic will be inhibited, protecting insulation and ice dam buildup on the roof will be reduced. The solar powered attic fan can be shut off in dry winter climates by a thermostat attached to the motor.
Broan solar powered attic fans are made in the US by a company that has set the standard in household ventilation for over seventy years. Broan fans ventilate up to 1,600 square feet of attic space and can lower the temperature in your attic by as much as 15 degrees. They run silently, even in partial sunlight, from dawn to dusk, insuring that your attic is cooled before the greatest heat of the day. By contrast, powered attic fans do not operate until a temperature is reached to trip the thermostat so that it plays catch-up with built-up heat and moisture conditions while the solar powered fan would have been operating from first light.
Broan's photovoltaic cell panel is highly sensitive and does not need to be angled to the light like other brand's attic fans, blending into the roof profile. They are available in colors that blend with the roof shingles or can be painted to match. The four varieties of fans available offer different configuration on your roof.
The surface mounted attic fan is the most popular model, designed for standard roofs without a steep slope or irregular shingles. The curb-mounted fan installs above a small box, or "curb" for irregular shingled or steep roofs to prevent water seepage. The remote mounted fan separates the solar panel and the fan so the panel can be mounted where light is optimal while the fan is mounted where it provides the best air circulation in the attic. The gable mounted fan also comes with the solar panel separated; in this case the fan mounts in the roof's gable space.
Broan solar powered attic fans provide 20 watts of power from dawn to dusk, contrasted with less expensive brands that only provide 10 watts of power. Those brands ventilate less square footage than the Broan solar powered attic fan, and cost less. The Broan solar powered attic fan has a variable speed motor allowing it to adjust speeds depending on available light. A federal tax credit of 30% of the cost of purchase and installation of a solar powered attic fan is available. It can be claimed on IRS form 5695 and applies to both primary and second homes.
You can be comfortable in your home with a durable Broan solar powered attic fan while knowing that you are not draining more electric power from the grid - that you can cool your house without spending more on electric power from your local utility.
