摘要

The design and simulation of PV cells are essential for predicting the performance of PV cells under different conditions, such as varying sunlight intensities, temperatures, and angles of incidence. This aids in understanding how the cells will behave in real-world scenarios and helps to optimize their efficiency. This paper presents the implementation of the equivalent circuit of the single-diode photovoltaic (PV) module through the utilization of the existing equations with the aid of Simulink blocks in MATLAB software. The model’s validity is verified for the DS-A1-80 panel, and I-V and P-V characteristics of a solar module are obtained for varying temperature and irradiance conditions. Subsequently, an alternative model is proposed utilizing the S-function builder in MATLAB. This study expands its evaluation to the analysis of computational time for these models on three different versions of MATLAB. Furthermore, a comparison of the computational time analysis between the two models has been conducted on the latest edition of MATLAB 2023b. The objective is to determine the optimal model for execution, enabling us to utilize this approach in simulating the model during the implementation of the solar charging station.
