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, so we recognized that change of solar irradiance is dominated by variation of blue~rich wavelength. Also in same intensity of solar irradiance, electrical output in blue-rich wavelength was 3-8 % higher than one in red-rich wavelength.

This paper, we proposed the theoretical model which includes series resistance R<SUB>s</SUB> and shunt resistance R<SUB>sh</SUB> of single-crystalline PV module and used numerical method based on physics. Series resistance R<SUB>S</SUB> was derived from approach for p-n junction diode instead of established form obtained from the simulator with irradiance changes. Electrical output characteristics for PV modules to count the effect of R<SUB>s</SUB> were then studied. Finally simulation results were compared to experimental data leading to good agreement.
