Performance Evaluation of PV Module by Dynamic Thermal Model

The response of the Photovoltaic (PV) module is dynamic with respect to the changes in its incomings. Steady state models of the operating temperature cannot be justified when rapidly changes of conditions occurs. In this paper, it is of interest to evaluate performance of PV module using dynamic thermal model. Electric circuit elements are used in the proposed dynamic model of PV module. Therefore, ‘Node Analysis’ method is applied for analysis of nonlinear circuit. In real conditions, the effective PV module operating temperature is affected by randomly varying of solar radiation, ambient temperature and wind speed. Hence, these have been applied as incomings of PV module dynamic model. Performance of PV module has been verified on two atmospheric conditions. Finally, the effect of incomings on operating temperature of PV module has been discussed.
