چکیده:

Consideration of the Current-voltage (I-V)characteristics variations of solar modules with temperature and irradiations variations is basic for maximum power point tracking (MPPT). Having a simple and accurate mathematical model for the optimize utilization of the solar modules is essential. In this paper, a novel modeling of photovoltaic systems with novel coefficients is proposed for mathematical description of the current-voltage (I-V) characteristic. Based on the proposed novel temperature and irradiation coefficients, the mathematical modeling of the solar modules is accurate. The accuracy of this proposed model is evaluated through comparison of simulation results to the data provided by experimental tests. The variations of maximum power point parameters (MPPP) versus irradiation and temperature in the experimental tests and the proposed model is evaluated. The proposed model is as well as adaptable for MPPT control operation
