Comparison Analysis on the Performance of the Filtered Photovoltaic (PV) Module

Abstract

The photovoltaic system is the most significant conversion device for solar energy compared to other available systems. It converts solar radiation into electricity, but the performance of the PV module degrades as the PV temperature increases. This is because only selected bands of wavelength, 0.35 to 0.82 μm, are converted into electricity while the remaining solar radiation will generate heat in the PV system. In order to maintain PV performance, the operating PV temperature can be maintained by applying various cooling methods, which are either passive or active. Some wavelengths, such as UV and Infrared, need to be eliminated. Therefore, this research aims to investigate the effects related to the presence of water in the filtered PV module. At the end of this study, the performance of the PV with and without the water filter was compared, and the results show that the PV module with the water filter achieved a higher efficiency of 9.96% compared to the filtered PV module without water, which had an efficiency of 9.61%.
