Effect of Operation Parameters on Efficiency of Photovoltaic Thermal Sensor Using Water

In this paper we study the thermal behavior of photovoltaic-thermal solar under a concentration with a heat exchanger and water is used as coolant. We present the influence of the external parameters on the electrical and thermal performance of the collector, the parameters affecting PV / T performance such as mass flow, temperature of the collector element, the absorbing impedance and the ratio of parabolic parabolic concentrator CPC are discussed. The intensity of the solar radiation was carried out for the slope of the collector at 30 ° C., which is a typical daily temperature in Constantine (eastern Algeria) to the surface cell. The obtained results are: The temperature increases throughout the system with the concentration compared to the situation without concentration. In addition, the concentration increases thermal efficiency and reduces energy efficiency when the fluid mass increases its temperature and the absorber decreases, the cell increases.
