8. Solar-Powered Attic Fans
Attic spaces can reach temperatures well in excess of 150 degrees Fahrenheit during scorching summer months, radiating intense heat down through your ceilings and forcing your central air conditioner to work overtime. Solar-powered attic fans offer a self-sustaining solution to this thermal overload by continuously pulling cool outside air through soffit vents and pushing trapped superheated air out through the roof, powered entirely by an integrated photovoltaic panel.
