Solar Fans for Attics

Description

• Solar attic fans on the market today have the latest solar panels that include state-of-the-art circuitry designed to capture sunlight, even when the day is overcast. Weatherproof panels can withstand hail and extreme weather. Designers pitched the fan blades for maximum air flow. A stainless steel screen allows maximum air flow while keeping out animals. Mounting hardware includes stainless steel motor brackets and vertical standoffs for easy removal.

Installation

• Installing a solar attic fan is easier than installing a conventional electric fan because you don't need to run electrical wires. Solar fans usually mount on the roof with power provided by a built in 10- to 20-watt solar-electric module, which generates direct current (DC) electricity. For best results, install the solar-electric module in a sunny location that is not at all shaded or shaded for only a short period of time each day. A large attic may require two solar fans.

Year-round Benefits

• Without a solar attic fan, attic temperatures during summer months may exceed 160 degrees with the excessive heat being passed back into the living space. During the winter, heat trapped in the attic can melt snow accumulated on the roof. Water trickling down can refreeze and damage eaves. Throughout the year trapped moisture from everyday activities like cooking and showering produce water vapor that can enter the attic. Moisture promotes growth of mildew and mold and can saturate attic insulation, leading to fungal decay.

Tax Credits

• The solar attic fan qualifies for a federal tax credit. According to the Solar Attic Fan Info website, both the purchase price and cost of installation qualify for a 30 percent tax credit. This applies to equipment purchased and put into service between Jan. 1, 2009 through Dec 31, 2016. Additionally, some states also offer tax incentives.
