Solar Powered Attic Fan retrofits into existing passive attic vents on rooftops and delivers lower attic and living space temperatures. Constant attic fan operation will result in reduced air-conditioner run times, which equates to electricity savings. Solar attic fans have a positive effect on roof shingle life expectancy. Isola's attic fans require zero electricity and are 100% solar-powered.
