Price/Performance Improvement Enabling Thin-Film on Rooftops

Historically, the residential and commercial rooftop solar energy market sectors have been dominated by solar modules using crystalline silicon wafers. Recently, the utility Southern California Edison began implementing the first phase of a 500MW project plan which is mainly supplied via 1MW installations on large (larger than 100,000 ft2) roofs. The program, which demonstrates the unique distributed generation nature of PV, is using First Solar thin-film product for some of the installation sites along with crystalline vendors including efficiency leader Sunpower . Once the exclusive domain of crystalline wafer modules only, the cost and efficiency of high performance thin-film product like First Solar’s produces acceptable internal rate of return for system owners on rooftops where many variables line up for this technology type. An article today in USA today features a good overview of the program and a picture of installers placing First Solar modules into service.
