Efficiency and power output enhancement by using multi-concept cooling technique for solar PV module

Maintaining a low operating temperature through the use of a passive cooling system is one method of increasing the efficiency of a photovoltaic system. As temperatures rise, photovoltaic modules’ performance declines. By attaching water flow inside copper and PVC pipe at the backside of the PV panel as a cooling device, this study investigates the effect on surface temperature reduction and voltage output of PV panel, with the goal of increasing and improving the effectiveness of electrical output by lowering the exterior surface temperature of the PV module. The experiment was carried out in Nagpur’s steady environment with constant outside temperatures between 32 and 34 degrees Celsius. Using a data recorder, the panel’s temperature and open-circuit voltage (VOC) were noted both before and after the cooling system was installed. To enable simultaneous recording of voltage and temperature data, the system was equipped with four thermocouples for each panel, as well as a voltage sensor, Pynorometer, anomometer. Solar irradiance ranging from 100 to 1000 W/m2, and non-uniform fluctuations in wind speed with a mean value of 1.5 m/s. The installation of the suggested cooling devices on the PV panel resulted in a surface temperature reduction of 4 o C or 7% and a voltage gain of 0.29 V or 2.8%, respectively.
