Photovoltaic performance modeling accuracy depends heavily on the quality of the input parameters. When relying on generic PAN files and datasheets, the input parameters often fail to accurately capture the behavior of every module with the same model number. Therefore, there is a need for methods to generate more accurate input data. In this study, we present a method for determining parameter values for the PVsyst version 6 photovoltaic module performance model from performance test measurements following the IEC 61853-1:2011 standard. The method is intentionally noniterative to facilitate implementation and reproducibility. We apply the method to datasets from 15 modules of various photovoltaic technologies (SHJ, TOPCon, IBC, PERC, n-PERT, Al-BSF, and CdTe), reproducing the original maximum power measurements with root-mean-squared (RMS) accuracy within 0.5% in all cases. The method's accuracy is compared to that of two iterative methods.
