If you wore a wool cap on a mid-day walk through the Sahara, you’d sabotage your body’s ability to properly ventilate. The same thing happens to your house when it’s 95 degrees outside, and your attic can get as hot as 160 degrees because there’s no mechanism for venting the steamy air.
This extreme heat generally makes for a less comfortable living environment, and strains air-conditioning systems in costly, inefficient fashion. An attic fan is a good solution, but the electricity they require can cost a couple hundred dollars per year. Solar attic fans, on the other hand, run on free energy supplied by the sun.
Solar attic fans can help effectively cool your house using free energy from the sun.
