A recent study shows that solar panel installed on the rooftops of the building can helps to keep cooling the building under the solar panels. Not only to cooling, the solar panels on the rooftops of the building can also add a little heat in the building during the winter.
The green energy and roof shades provided by the solar panels has been studied by UC San Diego Jacobs School of Engineering researchers. They used thermal imaging data to find out the ratio of heat between the building with solar panel installations and buildings without solar panels on the rooftops.
The difference of about 5 degrees F cooler due to solar panels can withstand the heat of the sun does not penetrate into buildings. It also benefited by the circulation of air through the space between solar panels and the roof of the building. While at night, solar panels can store heat in its thermal insulation, which it can help warm the building during the winter.
The development of solar panel use as renewable energy harvester from solar energy sometimes hampered by the installation costs which are still expensive.
The new findings allows us to calculate the cost that can be saved from the building's cooling system and the heating system. The double function of solar panels on the rooftops of the building can help cover the solar panel installation cost.
