摘要

This paper portrays a novel and enhanced unambiguous procedure that is suitable for the calculation ofthe six unknown one-diode parameters from PV-module data sheets. Before applying our proposed method to themanufacturer’s data of more than 2000 solar panels, the most crucial information was integrated with the simulationenvironment known as INSEL~?. After using the parameter identification procedure, whose routine was alsoimplemented as a block in INSEL, negative resistances were practically absent and the simulated solar cellcharacteristics did not seem to differ drastically from the exact calculations of a two-diode fit. When calculating athigh irradiances with the depicted procedure, the simulated performance showed negligible prediction errors withinan order of magnitude of around -0.2%, nonetheless at lower levels (< 200 W/m~2) underestimation errors as fromaround -23% took place. At a prediction level of approx. -3%, energy yield prognoses can reliably be simulated usingthe proposed parameter identification procedure.
