Abstract: Concentrated photovoltaic (CPV) system helps in focusing the direct solar radiation on the photovoltaic module. A CPV unit with water cooling system has been developed and manufactured at the School of Energy and Environment, Southeast University, China. It has been used for evaluating the performance of the CPV module with water cooling system for efficiency, power output and temperature. Also the effect of cooling water flow rate has been analyzed for performance evaluation of the CPV module. It has been found that the electrical output of the water cooled CPV is 4.7 to 5.2 times more than the PV module (without concentration and cooling). It has been noticed that the efficiency of the CPV mainly depends on the heat extraction rate and it helps in managing the cell temperature. And also the heat extraction rate from the CPV module mainly depends on the cooling water flow rate.

Keywords: Photovoltaic, concentrated photovoltaic system (CPV), water cooled CPV
