PV Modeling and Extracting the Single-Diode Model Parameters: A Review Study on Analytical and Numerical Methods

The electrical modeling of photovoltaic modules is essential for installing, optimizing, and controlling photovoltaic systems. Several electric models exist, including the single-diode model (SDM), which has five unknown parameters. The challenge at hand pertains to determining these parameters, for which several methods are available. These methods are distinguished by their precision, complexity, and applicability. Generally, there are three categories: analytical (non-iterative), numerical (iterative), and metaheuristic methods. This work compares and tests the accuracy of eight analytical and numerical methods for determining the parameters of a single-diode model. The eight methods will validate on a PV module is Shell SQ160-C under standard test conditions (STC), and all give a realistic result for determining the unknown parameters and predicting the I-V curve.
