Analysis and Modification in Cooling System Using Solar Photovoltaic Module | Original Article

ABSTRACT:

Under the project, the effects of fins cooling (passive cooling) and water cooling on performance parameters of solar photovoltaic (PV) module have been done. In the system of fin cooling, an aluminium sink containing fins have been attached to the backside of PV module in order to dissipate efficiently the waste heat from it. In the second method, a water film is created by continuously circulating the water over the surface of solar panel using a pipe distribution system to the top of the panel. After completion the test, it have been concluded that the power and the electrical efficiency of the cooling PV system are higher than the traditional one. It have also been found that the module temperature of the fins cooling method has maintained it 3°C to 5°C below the conventional reference module and the percentage increase in electrical efficiency is 2.1% to 5.85%. Whereas the module temperature of water cooling method has maintained at 15°C to 28°C below the conventional and the percentage increase in electrical efficiency is 6.9% to 16.9%.
