Real-Life Performance and Customer Feedback

In considering customer reviews, the U.S. Sunlight Corp Solar Powered Attic Fan 1010TR elicits mixed responses. Many customers note that the fan works excellently in reducing their attic temperatures, especially during peak summer periods. One customer with a century-old brick bungalow remarked on how the attic fan considerably lowered the heat in their finished attic, which had previously been unbearable. Another customer reported that the fan managed to reduce their attic temperature by an impressive 30 degrees overnight and sustained its performance even 13 years after installation.

On the other hand, some customers express dissatisfaction with the fan’s performance. The most common complaints highlight the fan’s inability to maintain consistent operation, particularly during cloudy days or periods when the sun is out of range. The exclusion of the power adapter from the initial package seems to be a significant point of frustration, with customers feeling that they have been short-changed or forced to incur additional expenses to get the fan running optimally. One customer compared prices and found that the unit plus the power adapter were cheaper at Costco than purchasing separately on Amazon.

In addition, a considerable number of users were dissatisfied with the fan’s performance compared to electric fans. A user who replaced two small electric fans with two 1010TR fans noted that while they expected some drop in performance, they were disappointed by how much less efficient the solar attic fans were. Despite the documentation suggesting that the solar fans should be sufficient, the user noted that their attic temperature was significantly higher when using the solar fans compared to the non-solar electric ones.

Furthermore, some users encountered issues with the solar controllers. Customers reported frequent faults and error messages, requiring regular attic visits for reboots. However, when these customers received updated controllers from the company, the errors were largely resolved.

Lastly, some users had concerns over the fan’s power. There were claims that the fan could not cover the area it advertised, leading to underperformance and ineffective temperature control. A user from Costco commented that the temperature difference between the outdoor and attic, even at solar noon when solar efficiency is highest, was about 30°F, far from their expectation of a 10°F difference. They urged the company to address these inaccurate claims.

Overall, it seems the U.S. Sunlight Corp Solar Powered Attic Fan 1010TR is appreciated for its potential to lower attic temperatures and reduce energy costs, but there are definite areas of concern around its performance, controller stability, and the lack of a power adapter in the initial package.
