Abstract

The solar irradiation is one of the major factors must be taken into consideration in the design and employment of photovoltaic system. On other side, another major factor is surface temperature of photovoltaic panels which effect their conversion effectiveness. The produced power of PV system is reducing in the same situation of solar irradiation, while the operating temperature is high. Photovoltaic thermal collector (PVT) is a new hybrid technology for PV system that output heat and electricity together, so employment of this technology must be taken into consideration to improve the performance of PV system. The present study purpose is to estimate the impact of using water and air collector on the performance of PV/T system. Employment a water riser tube and absorber plate in the suggest of models to consider the conduction and convection heat transfer mechanisms. By employment of computational fluid dynamics (CFD), the numerical results were obtained by employing conjugate heat transfer. This paper presents thermal performance analysis of different designed configurations as spiral flow, oscillatory, direct and web flow air collector heat exchanger employed in hybrid solar PV/T system. A numerical way of the decreasing of temperature of photovoltaic panel is offered in this research. By utilizing ANSYSFLUENT software for laminar and turbulent flow, the numerical model was recognized, and the outcome is offered for the average temperature of photovoltaic panel.
