QuietCool Solar Attic Fans are the best in the industry offering the largest panels at an affordable price. This fan features a 65-Watt solar panel, an adjustable thermostat, an ultra-energy efficient DC motor, a heavy-duty steel housing, and an included AC/DC inverter. Solar attic fans work by using sunlight to power the fans motor to help prevent any heat or moisture build up in your attic. Your attic can reach temperatures of up to 150°F which can destroy the integrity of your home as well as completely destroy your roof because of the humidity and moisture build up. Because of this, solar attic fans can prolong the life of your roof structure and air conditioning while helping you save up to 30% on A/C costs. With a QuietCool Solar Attic Fan, you also get the benefit of an included AC/DC inverter. This allows the fan to run 24/7. When there is sunlight outside, the fan will run only on solar power being powered by the large solar panel on the fan. When there is no sunlight, such as at night, the fan will switch to AC power and continue to run throughout the night. This allows you to take advantage of cooling your attic during the coolest part of the day. Simply mount the fan to your roof and plug in the inverter to enjoy 24/7 cooling and ventilation in your attic.

3 years of reliable operation on solar only, using no plug in power. Doesn’t run unless there’s direct sun on it but cranks up high when’s it’s really shining. Effective quiet and so far reliable. A brushless design at this cost point should work for many years, so far so good. Performance completely reliant on air vents to allow for storing air movement. We installed large soffit vents throughout so it works very well. Without ample air admittance any fan would be minimally effective and die a premature death. Don’t expect a product to defy the laws of physics people, the fan itself is only part of the solution.
I purchased this attic fan Jun 2023. Today is Aug 2025 so this review is a complete 2+ year review. Shipping great as expected, packaging was great as expected. I live in central Texas and we go through temperatures of 90 to 105+ degrees during our summers. My attic we'll surpasses that. Let me say this fan has worked flawless in the hottest summers the attic is noticeably cooler around the area where it's installed and during our summers it runs nonstop all day and won't stop until we'll in the mornings. It's quite and moves a lot of air and built like a tank. I will probably buy another 2 or 3 due to the size of my attic. Hands down we'll worth the money!
Easy to i stall. Works great.
Was very easy for our contractor to install. Super quiet - has already made a huge difference in humidity levels and musty attic smell on second floor. Very happy with this roof mounted fan. It wasn’t super hot today but hoping the HVAC system on our second floor runs more efficiently.
