It turns out that solar panels can do more than provide you with renewable energy –¬†they can significantly cut down the power needed to heat and cool your building as well.
The team of researchers, led by Jan Kleissl, a professor of environmental engineering at the UC San Diego Jacobs School of Engineering, discovered that the amount of money saved on heating and cooling costs could add up to a 5% savings on the total cost of the solar panels if factored in as energy saved. Instead of the sun beating directly onto the roof and heat seeping through the roofing material and into the building, the solar panels absorb that direct sunlight, turn it into energy and divert the heat from the building. Elevating them over the roof acts as a heat shield, cutting radiant heat gain by 50% or more, for about a 60% reduction in solar heat gain on the part of the roof they cover.


A green roof will extend the life of the waterproofing membrane that the solar panels are installed on top of and will keep the roof even cooler.
The biggest cost of solar is not the panels themselves but theinitial installation and take-down of the system in case the waterproofing needs to be replaced. In a study recently released in the journal Solar Energy, an engineering team at UC San Diego found that the presence of solar panels on rooftops keeps buildings an average of 5 degrees Fahrenheit cooler during the day and keeps heat in during the nighttime, which could save cash on heating costs in the winter. The team used thermal infrared cameras to capture temperature data from the rooftop of the Powell Structural Systems Laboratory at the Jacobs School of Engineering which has been outfitted with tilted solar panels and solar panels flush with the roof, while also maintaining some exposed areas.


The panels, especially the tilted kind, create wind tunnels where heat is swept away from the building as it moves between the panels and the rooftop. The team found that solar panels could reduce heat reaching the rooftop by as much as 38% and the more efficient solar panels had higher heat redirection rates.
