CHICAGO (Reuters) - A new type of reflective coating can make solar panels far more efficient, soaking up nearly all available sunlight from nearly any angle, U.S. researchers said on Monday.
Current solar panels -- which convert energy from the sun into electricity -- absorb only about two-thirds of available sunlight.
But surfaces treated with a coating developed at Rensselaer Polytechnic Institute in Troy, New York, can harvest 96.2 percent of sunlight.
By pay back, I mean the amount of time it takes a solar panel to create an amount of electricity equal to the price of the panel based on your local utility's electrical rate. Essentially when buying a solar panel you are buying your electricity up front before you use it. Any electricity created after the pay back period is free!
