Family Saves Money in Energy Bills Using Solar Powered Fans

Solar Powered Fan Testimonial—Updated with 2014 Data

In September 2011, the Whisenhunt family in Longmont, CO wrote Air Vent a letter expressing how pleased they were with the performance of their Air Vent roof-mount solar powered fan they installed near the end of the summer 2010. “We have been comparing our electric usage before and after installation,” they wrote.


 

 

 

“The results are that the fan has saved enough in electric bills to nearly pay for the cost of the fan.” Prior to installing the fan they used 7 roof louvers for attic exhaust ventilation. The Whisenhunts installed a second roof-mount solar powered fan April 2012. The charts below show the kilowatt usage and the average temperatures before and after the installation of the fans.

 

Pay particular attention to June-August 2010 vs. 2011, 2012, 2013 into 2014. And see the dollar savings. Finally, see the “Notes” section in which the Whisenhunt’s documented the attic temperatures vs. outdoor temperatures. Their readings fall right in line with Air Vent’s recommendations that a balanced attic ventilation system should keep the attic no more than 15-20°F higher than the outdoor temperature.

 

Note: The Whisenhunt family saved $183.69 in total June-August 2011 vs. the previous year for the same time period. In each of the next two summers they continued to save money compared to 2010 despite higher overall outside temperatures and hikes in electricity costs. The 2012 savings = $157.59. The 2013 savings = $201.11.
