So, United Solar Ovonic "uses a morph of silicon?" I was wondering how their product will perform if they start using two or three morphs, for example. Uni-solar's panel-level efficiency is indeed a low 6.3%, but at least they have a product that reportedly had sales of 109 MWs last year, manufactured at $2 per Watt. ASTI has nothing. They apparently do not even have a product (just a lab experiment, with unproven usable life and high cost of manufacturing). And ASTI should stop perpetuating the myths that 1) somehow there are roofs in the United States that cannot withstand glass solar panels on non-penetrating racks (a total of less than 5 psf extra dead load), and 2) installation costs for laminates are lower than for glass solar (as the rack savings are overwhelmed by ASTI laminates' low-efficiency relative to crystalline panels, as well as the inability to tilt).

I thought the Cleantech Group knew at least something about PV technologies...
