The aim of this study is to establish an effective modeling technique for simulating the performance of photovoltaic modules by calculating their electrical parameters based on the two-diode model. The suggested methodology involves reducing the scope of the study from seven unknown parameters to only three, and that without resorting to any approximations. The first four parameters are calculated analytically based on the data representing the crucial positions on the current-voltage graph and using a new expression of the fill-factor derived from the two-diode equivalent circuit. The remaining parameters are established numerically based on a simple iterative technique adaptable with two sites of data availability. The photovoltaic modeling begins by utilizing the values of key-points. Subsequently, to ensure the proposed approach's adaptability to various scenarios of available information about PV generators, it is invested and applied for an optimization process. The accuracy is evaluated for diverse types of photovoltaic modules, and the results are weighed against widely reviewed numerical methods and evolutionary optimization algorithms in the literature. As a result, the new method demonstrates superior performance, yielding the smallest values for the utilized statistical indicators and reducing compilation time. These findings underscore its flexibility and high efficiency in simulating photovoltaic devices.
