The Effect of Additional Air Deflector at Air Concentrator on Photovoltaic Performance

The supply of fossil energy is decreasing along with the development of civilization and technological advances. Solar energy is one of the renewable energies that can reduce these problems. Solar cells can convert solar energy into electrical energy using the principle of the photovoltaic effect. The performance of photovoltaic panels is affected by the increase in temperature in the photovoltaic panels. This study aims to identify the effect of increasing the number of deflectors on the air concentrator which is implemented as an active cooling of solar cells. This research was carried out experimentally by integrating an air concentrator, deflector, and heatsink on a PV panel. The application of various without concentrators, concentrators without deflectors, concentrators with two deflectors, concentrators with four deflectors, and concentrators with six deflectors, the temperature values are 56.70℃, 54.66℃, 53.30℃, 51.63℃ and 53.70℃. From several variations of the addition of deflectors that have been carried out, it is found that through the application of a concentrator using four deflectors can obtain the most optimal results by producing a maximum power of 24.50 W with a total efficiency of 6.35%. In this configuration, a temperature drop of 5.07℃ is obtained.
