When the photovoltaic generation system suitable for sun direction installed reflector was designed, the solar irradiance on PV panel by a fixed method and a tracking one was calculated. Moreover, the installation angle installed the upper and lower side reflector, the reflected solar radiation, and the shadow length were calculated. As a result, it is cleared that the tracking is effective on the clear days except at noon, the best angle installed upper reflector is from 20 to 30 degree, and the one installed lower reflector is 60 degree. The measuring data was obtained from September 2009 to February 2010 except for the period in bad condition of instruments and in unseasonable weather. As a result, an actual measurement of power conversion efficiency of PV panel was obtained from measuring data in February 2010 when the PV panel was fixed in the direction to directly south.
