Hi,
Solar PV shingles or metal roofing made from thin film will also lower the price a lot. NanoSolar "prints" a coating on metal films -- they do not use silicon wafers at all! And, they do not use frames, or glass, and they do not have the same uplift and dead load problems that panels have. So in the end, they are a LOT less expensive!
I have heard the $1/watt number mentioned, for these types of PV.
