The reported capacity credit values have been used for onshore without any adjustment. The capacity credit values for offshore have been adjusted to take into account its higher load factor values. A recent study (Jones, 2012) evaluates capacity credit for PV for the California electricity system, assuming a broad range of solar installed capacity. Resulting capacity credits are quite high with 27% and 11% respectively, which reflects both the high load factors and the good correlation with peak demand in the south west of the United States.
