Field performance modeling of Semprius CPV systems

Semprius, a producer of high concentration photovoltaic (CPV) modules with world record efficiency, has developed capabilities for modeling field performance of CPV modules using two performance models: PVsyst and Semprius Performance Model (SPM). Modeling with PVsyst relies on the definition of a PAN file which is described here. SPM is the result of Semprius´ collaboration with Sandia National Laboratory to develop software that can accurately model the field performance of Semprius CPV systems. The performance of both PVsyst and SPM is demonstrated for Semprius CPV by validation against actual Semprius CPV systems operating in the field, one in Tucson and one at Sandia National Labs, NM. These comparisons suggest that both of these models can accurately predict annual AC energy yield to within 1-3 percent.
