Solar Dormer Vent attic fan. Cool your hot attic no wiring required, powered by the sun for free. Each fan covers approximately 1200 sq. ft. of attic area. These fans are great for cooling the attic, which during the summertime can reach temperatures upwards of 150 degrees farenheit. Moreover, keeping the attic cooler allows A/C ducting to remain cooler and allow your A/C systems to run more efficiently.
