In this study, an attempt was made to investigate the wavelengths of light and its effects on the performance of solar photovoltaic module. A case study was conducted to experimentally verify the effect of various colour filters (polythene) on the performance of solar photovoltaic module. Based on the temperature of the cell, solar irradiance and photonic theory, the efficiency and power output of the PV system have been evaluated. An analytical model based on physical parameters was also developed to evaluate the efficiency of solar panel. The results show that the Present day PV technology is influenced by the red color of light. In other words, visible portion of the solar spectrum influences the performance of the solar panel then the infra-red light.
