Abstract

Solar energy is one of the most important renewable energy sources that effectively contributes to meeting the growing global demand for electricity while reducing carbon emissions. Despite the high performance of photovoltaic (PV) modules, accurate quantitative analysis of the impact of varying environmental factors on them using dynamic modeling remains essential for improving their performance in field conditions, particularly solar irradiance and temperature. This study aims to model and simulate the electrical performance of a high-efficiency SunPower SPR-415E-WHT-D PV module using MATLAB/Simulink by analyzing the current-voltage (I-V) and power-voltage (P-V) curves. Simulation results showed that increasing irradiance leads to a significant increase in maximum power, which rose from 18.7 W to 424.8 W when irradiance increased from 200 W/m² to 1000 W/m². In contrast, rising temperature causes a decrease in voltage and consequently power, with the maximum power decreasing by 5.27% when the temperature increased from 15°C to 35°C.
