only deliver between 7 and 10% efficiency Many articles say that the thin film has a much lower efficiency than silicon cells. But that does not mean much to me. A much more meaningful measurement is the typical energy output per dollar of installed fixtures. By installed cost that includes labor, materials and shipping costs. A 2% efficiency would be terrific if I could cover my roof with the stuff for $100. A 100% efficiency would be worthless if it cost a million dollars for a 100 W panel. Right now all of them are too expensive. A guy I work with on Kauai, Hawaii says some people have the panels on their house. However even at 31 cents per KW-HR for retail electricity, panels are too expensive to justify on economic basis.
