The “five-parameter model” is a performance model for photovoltaic solar cells that predicts the voltage and current output by representing the cells as an equivalent elec-trical circuit with radiation and temperature-dependent components. . In this research, the single-diode model's step values for each parameter are evaluated, to identify the optimal step value for four parameters: ( {R}_ {s}), ( {R}_ {sh}), (n), and ( {I}_ {ph}). The PV panel parameters could be used for PV panel health monitoring and fault diagnosis.
