Solar power Systems Do More Than Generate Electricity
If you're looking the additional reason to find a solar power system, here you go. Solar panels aren't just an environmentally friendly to be able to generate power for your own or business and to save on rapidly escalating discovered another means - they can help out with keeping your house or place of business cool too, helping you conserve lots of even more on energy.
A team of researchers at UC San Diego Jacobs School of Engineering carried out a study in 2011 to examine the cooling benefits of rooftop solar modules using thermal imaging. The researchers found a building's ceiling was up to 5 degrees Fahrenheit cooler underneath the array than under an exposed section of rooftop. Additionally, the panels can help to keep heat in at night during winter.
Jan Kleissl, a professor of environmental engineering who led the research, says his team has determined the savings through a solar panel's insulation qualities amounts to a 5% discount on the cost of the modules over their lifetime.
The panels act as shades, preventing the the sun from beating down directly onto the ceiling. While solar panels do heat up, much of the heat taken out by air movement between the panels and the roof. The greater the gap, such as are going to be found in a tilted array, the greater the benefits. They also found slightly more efficient the solar power panels are in converting sunlight to electricity, the bigger the cooling effect, as heat is a by-product of inefficient conversion. In the team's tests, the panels reduced amount of of heat striking the roof by about 38 percent.
While Professor Kleissl acknowledged there are of course more efficient ways to insulate buildings, it's just an added energy efficiency bonus through installing a rooftop solar power system.
The results among the testing show a rooftop solar array's insulating qualities undoubtedly are side benefit substantial enough to utilized into consideration when creating a purchase desire. It's this characteristic exercises . further bolsters the case for turning the water of rooftops in towns and cities into massive distributed electricity generation systems to help lessen load on centralized power generation.
Additional benefits of a decentralized electricity generation system with energy as the centerpiece are a lowering of infrastructure investment by network operators and lessening line loss associated with power transmission; which can account for almost 10% of electricity production. Solar panels also generate their peak electricity during major consumption periods; so with greater uptake, fewer fossil-fuel burning peak power plants would truly be constructed.
