Parameters Extraction of Single Diode and Double Diode Models Using Analytical and Numerical Approach: A Comparative Study

This review paper provides a comparative study between analytical and numerical approaches. The purpose is to estimate the unknown parameters of the single diode and dual diode models. Nine of the most common models are examined in depth, detailing the parameter calculated, the most important approximations characterizing each model, and the calculation process. The effectiveness of the methods studied is assessed under various temperatures and solar irradiation conditions for three types of PV modules using various technologies, such as single-crystalline (CS6V225M), multi-crystalline (CS6P265), and thin film (ST40). The quality of the models fitting to the measured data is assessed by statistical analysis. Results of the study indicate that(1) the temperature exhibits a fairly low impact on the key points of the I-V characteristics of the solar panel, particularly under short and open-circuit conditions, and that(2) the open-circuit voltage at low solar irradiance, as shown in I-V curves, is underestimated. The results of the simulation show that the performance in terms of accuracy varies from one technology to another and the same technology varies with the conditions of temperature and solar irradiation. It is expected that this work will be useful to update the knowledge in the field of PV modeling and simulation.
