The power output of solar panels can be boosted by 10 percent just by applying a big transparent sticker to the front. Developed by a small startup called Genie Lens Technologies, the sticker is a polymer film embossed with microstructures that bend incoming sunlight. The result: the active materials in the panels absorb more light, and convert more of it into electricity.
The article says this material works better in areas where more light is diffuse due to cloud cover. Well, Nick G recently pointed me to a good source for seeing where in America a larger fraction of the light gets redirected on its way to the surface. This pair of maps of insolation for photovoltaics and concentrating solar power provide a good visual way of seeing where a polymer film cover would work especially well to boost PV output:
Areas which shift from a hotter color in the photovolaic solar image to a cooler color in the concentrating solar image are the best candidates for benefit from using the polymer film described above.
