Amplification of Solar Radiation Intensity on Photovoltaic Panel Using Reflectors to Increase Power Output

Abstract

Solar energy is a significant renewable energy source and has great potential to replace fossil energy in power generation. Although photovoltaic (PV) panel technology has progressed rapidly, PV panels have the disadvantage of being less optimal in absorbing the intensity of solar radiation which will have an impact on the output power and efficiency of PV panels. To overcome this, the use of reflectors as a method of concentrated solar radiation has become a promising solution. This study aims to investigate the effect of adding reflectors on PV panel performance through experimental and simulation approaches. The design configuration, angle, and number of reflectors used are evaluated to achieve optimal PV panel performance. In addition, the effectiveness of different reflective materials was also analyzed to determine the effect of reflector materials in distributing solar radiation. The results showed that the addition of reflectors to PV panels can increase the distribution of solar radiation received, thereby increasing short-circuit currents that have an impact on the output power and efficiency of PV panels. The tilt angle and design configuration of the reflector affect the amount of sunlight that can be reflected onto the PV panel. The results also showed that the selection of appropriate reflective materials can improve the collection of solar radiation.
