PV power performance is modelled either from indoor (usually matrix, flash test) or outdoor (time series) measurements. PV technologies (e.g crystalline Si, CdTe, CIGS) can depend differently vs. irradiance and module temperature. PV Performance models (e.g. equivalent circuit, curve fitting or empirical/mechanistic fit ) derive their coefficients from fitting either IV curves or else just derived points (such as Isc or Vmp). For dc energy predictions the power performance vs. plane of array irradiance and module temperature are summed from time series from site climate data (with plane of array calculations and thermal models). For AC performance the balance of systems components are also modelled (e.g. wiring loss, mismatch, inverter efficiency, shading etc.) Detailed data analysis can determine performance losses – tolerances, sensitivities to inputs, seasonal effects and degradation which should be minimised for optimum output.
