Abstract

Recently, characteristic research by the changes in the spectrum, one of the factors that influence analysis of maximum output power of PV module, has been studied. In this paper, a one-day intensity of solar irradiation, change of spectrums with time and electrical output for spectrums are analyzed. As a result, blue-rich wavelength compared with red-rich wavelength has large variation of solar irradiance with time. It is recognized that change of solar irradiance is predominately on variation of blue-rich wavelength. Also in same intensity of solar irradiance, electrical output in blue-rich wavelength was 4-8[%] higher compared to in red-rich wavelength.
