The solar panels on the roof of a house not only produce clean electric energy and environmentally friendly. The panel was also cool your home or place of work. A team of researchers led by Jan Kleissl, professor of environmental engineering at the Jacobs School of Engineering at the University of California (UC) San Diego, reveal the benefits of cooling temperatures provided by solar photovoltaic panels.
In a study to be published in the journal Solar Energy, Kleissl and his team do hot imaging to calculate that effect. They found that, during the day, the temperature of the ceiling of the building under the solar panels of three degrees Celsius colder than usual under the roof. At night, the panel was keeping the heat remains inside the building, reducing heating costs in winter in the country of four seasons. "Look at the positive effects," said Kleissl.
Sunlight, which is usually baked roof and cause heat through the roof and ceilings of buildings, now blocked by a solar panel that absorbs the heat. Most of the remaining heat is lost in the wind that blows between the panels and roof.
The benefits of cooling will be even greater if there is an open gap where air can circulate between the building and solar panels, so the panels are mounted sideways to give a greater cooling effect. "The more efficient solar panels, the greater the cooling effect," said Kleissl.
The researchers analyzed the solar panels down the heat on the roof up to 38 percent. "There's a much more efficient way to cool a building passively, such as reflective roofing membranes," he said.
