Staying Cool with Solar Power

Thought solar panels were only good for providing solar power? Researchers are finding that solar power is not the only benefit. Solar panels have been found to reduce rooftop temperatures by as much as 38%.   A recent study found that areas shaded by the panels were 5 degrees Fahrenheit cooler than parts of the roof exposed to the sun.

The solar panels absorb the suns heat and act as a shade for the roof. In situations where there are gaps between the panel and the roof, the roof is cooled more efficiently; the same goes for highly efficient solar panels.  This new discovery adds to the already known benefits of solar power by reducing the need for cooling buildings.  In an effort to encourage solar panel usage, companies such as SunPower are leasing panels.
