As it turns out, the solar energy panels on top of your roof are not just providing clean renewable power, they’re also cooling your home, according to a gang of engineering analysts at the UC San Diego Jacobs College of Engineering. Using thermal imaging, analysts determined that during the daytime, a building’s ceiling was five degrees Fahrenheit cooler under solar energy panels than under an exposed roof.

As solar energy panels sprout on a rising number of home and commercial roofs, it becomes more crucial to consider their result on a buildings ‘ total energy costs. Analysts determined the total saved on cooling the building amounted to getting a five % discount on the solar energy panels price, over the panel’s lifetime.

Or to put it in a different way, savings in cooling costs amounted to selling five % more solar electricity to the grid than the solar energy panels were directly generating for the building that was used in the study.

A thermal infrared camera was used to gather the info for the study over a few days in Apr 2011 on the rooftop of the Powell Structural Systems Lab at the Jacobs College of Engineering. Naturally there were portions of the roof that were not covered by the solar energy panels.

Essentially what this means is that the solar energy panels shade the roof. Instead of the sun thrashing down onto the roof, causing heat to be penetrate the roof and ceiling of the building, the solar energy panels take the solar thrashing. The result is that a significant amount of the heat is removed by wind blowing between the solar energy panels and the rooftop.

The advantages are more significant if there’s an opening between the building’s rooftop and the solar energy panels, so elevated or tilted solar panels provide a greater amount of cooling. Though the measurements happened over a short period of time, it is presumed that the evidence thus far makes it possible to forecast cooling effects throughout the year. With this in mind, it is worth noting that if you’re considering installing solar photovoltaic, you may expect a significant decrease in the quantity of energy you use to chill your residence.
