According to a study by Jan Kleissl for an upcoming issue of Solar Energy, solar panels just don’t provide clean energy but also cool buildings, workplaces and homes by nearly 5°F than under an exposed roof. A professor of environmental engineering at the UC San Diego Jacobs School of Engineering, Jan Kleissl led his team of researchers to this discovery during their study of the cooling advantages of photovoltaic panels. While solar panels provide power and cool buildings in the day, they hold the heat in at night, lowering heating costs during winters.

These days consumers are depending more on solar energy to power their houses and offices. So its necessary to evaluate the exact positive impact of solar panels on the energy costs, Kleissl said. He research discovered that the amount saved on cooling the building equaled five percent discount on the solar panel’s price over a lifetime. (more…)
