“…Using MATLAB/simulink Gupta et al [22] simulated an improved two-diode model of PV module; the accuracy of the model was validated by testing various modules of different type (multi-crystalline, mono-crystalline and thin film). Mahmoud et al [23] proposed a parameterization approach for PV models to improve modelling accuracy and reduce implementation complexity; the effectiveness of the approach was evaluated by comparing the simulation results with the experimental data of mono-crystalline, multi-crystalline, and thin film PV modules.…”

“…Early models for PV cells and panels, which were presented by Chan et al [40], Enebish et al [41] and Hovinen [42], were conceived to calculate the I-V characteristic at certain values of solar irradiance and cell temperature, which can be the SRC or any others. Some models, able to give a complete representation of the performance curves for any condition different from the SRC, were proposed by Ishaque et al [43], Gupta et al [44] and Hejri et al [45]. Such recent models face the complex problem of the analytical solution of the involved equations by assuming some simplifying hypotheses and/or reducing the number of independent parameters.…”

Many diode-based equivalent circuits for simulating the electrical behaviour of photovoltaic (PV) cells and panels are reported in the scientific literature. Two-diode equivalent circuits, which require more complex procedures to calculate the seven model parameters, are less numerous. The model parameters are generally calculated using the data extracted from the datasheets issued by the PV panel manufactures and adopting simplifying hypotheses and numerical solving techniques. A criterion for rating both the usability and accuracy of two-diode models is proposed in this paper with the aim of supporting researchers and designers, working in the area of PV systems, to select and use a model that may be fit for purpose. The criterion adopts a three-level rating scale that considers the ease of finding the data used by the analytical procedure, the simplicity of the mathematical tools needed to perform calculations and the accuracy achieved in calculating the current and power. The analytical procedures, the simplifying hypotheses and the operative steps to calculate the parameters of the most famous two-diode equivalent circuits are exhaustively described in this paper. The accuracy of the models is tested by comparing the characteristics issued by the PV panel manufacturers with the current-voltage (I-V) curves, at constant solar irradiance and/or cell temperature, calculated with the analysed models with. The results of the study show that the two-diode models recently proposed reach accuracies that are comparable with the values derived from the one-diode models.

Moreover, in order to assess the range of dispersion of the results, also the maximum difference (MD) for current and power was evaluated using the following relations:…”

Models for photovoltaic (PV) cells and panels, based on the diode equivalent circuit, have been widely used because they are effective tools for system design. Many authors have presented simplified one-diode models whose three or four parameters are calculated using the data extracted from the datasheets issued by PV panel manufactures and adopting some simplifying hypotheses and numerical solving techniques. Sometimes it may be difficult to make a choice among so many models. To help researchers and designers working in the area of photovoltaic systems in selecting the model that is fit for purpose, a criterion for rating both the usability and accuracy of simplified one-diode models is proposed in this paper. The paper minutely describes the adopted hypotheses, analytical procedures and operative steps to calculate the parameters of the most famous simplified one-diode equivalent circuits. To test the achievable accuracy of the models, a comparison between the characteristics of some commercial PV modules issued by PV panel manufacturers and the calculated current-voltage (I-V) curves, at constant solar irradiance and/or cell temperature, is carried out. The study shows that, even if different usability ratings and accuracies are observed, the simplified one-diode models can be considered very effective tools.
