Video is from Google video. Installing clean, reliable, inflation-proof solar power is easier than ever, thanks to the invention of thin-film photovoltaic (PV) laminates that can be bonded directly onto metal roofing panels. Unlike crystalline PV material, there's no need for obtrusive racks and heavy, expensive glass. Instead, unbreakable thin-film PV is produced using amorphous silicon, encapsulated in Teflon and other polymers. http://www.uni-solar.com/index.asp http://www.etaengineering.com/panels/unisolar.shtml http://www.mhi.co.jp/power/e_a-si/index.html http://www.bigfrogmountain.com/powerfilmsolarproducts.htm
