The paper discusses temperature and solar radiation’s effects on the photovoltaic model (PV) with changeable values. Matlab-Simulink is using to modeling the mathematical equations of the PV model to predict the behavior of the output current and voltage of the PV model. Simulation depends on the constant temperature on the PV model with different solar radiation values and vice versa. Thus, a comparison of the simulation results with the PV model datasheet under standard test condition STC. The results indicate the affected of the current and the output voltage by the decrease of solar radiation even with constant temperatures, which was evident in I-V and P-V curves’ values. The performance of the PV panel affected at high temperature even with a constant value of solar irradiation, while decreasing the temperature contributes to an increase in the PV model output power.
