Besides being eco-friendly, solar powered attic fans take their energy from the sun so there's no need for wiring. A solar attic fan is a super way to make your home more energy efficient without paying a ton of money. Not only are solar powered attic fans an inexpensive way to add solar energy to your life, they also help you save money. Your investment will quickly be amortized as you watch your electric bill quickly drop.
Solar powered attic fans exhaust hot air from your attic by using energy from the sun; some solar attic fans also use wind energy. Typically installed on a rooftop or end-wall, solar powered attic fans work when sunlight hits the solar panel. Solar powered attic fans provide benefits year-round, even in the winter. Although excessive attic heat is not typically a problem in the wintertime, winter attic ventilation helps to prevent moisture build-up that might dampen insulation, contribute to mold growth, structural rot, or damage items stored in the attic. As a result, excess moisture build-up can have negative consequences not only on the structure of your home, but you and your family's health.
In addition to reducing harmful allergens in your home, a solar attic fan increases the life of your roof by keeping it at a lower temperature, reducing moisture buildup. Since your roof is a major investment in your home, solar attic fans help protect this investment. Finally, a solar attic fan is simple to install and requires very little maintenance.
