The search for high efficiency and accurate modeling in the analysis of photovoltaic (PV) cells has necessitated the development of special software programs. This software focuses on determining series and parallel resistances in the equivalent circuit of photovoltaic cells. Accurate modeling of these resistors is of great importance to understand and optimize the performance of PV cells under different operating conditions. Software programs use advanced algorithms and simulation techniques to extract and measure the series and parallel resistances associated with the equivalent circuit of the PV cell. It provides a comprehensive and realistic representation of cell behavior, taking into account factors such as temperature changes, irradiance levels and material properties. Researchers and engineers can use this software program to analyze the impact of series and parallel resistances on the overall performance of PV cells, making the analysis of solar panels easier. This software program can contribute to ongoing efforts in improving the accuracy of PV cell modeling and analyzing the efficiency of solar energy conversion systems. Newton-Raphson, Genetic Algorithms, Particle Swarm Optimization (PSO) etc. are used to predict and analyze the series and parallel resistances in the PV cell single diode equivalent circuit. methods are used. In this study, the Newton-Raphson method was used in the analysis process. The software program prepared in MATLAB and given in Appendix –A- was used to find the PV cell equivalent circuit series and parallel resistances.
