The efficiency a solar cell system us mainly affected by the solar incident angle on the photovoltaic panels. The purpose of this thesis is to investigate a solar light-tracking BIPV system as the applicability on the educational facilities. Two typical types of BIPV system by operating system; fix PV panel type and rotating PV panel type, are analyzed in the performance of electric power generation and compared with solar light-tracking BIPV system. The simulation of solar irradiance is performed using ECOTECT, which has various advantage such as easy user interface and simple simulation processes. In order to evaluate the electric power generation efficiency, the electric power generation rate and global irradiation were measured on the spring/autumn equinox and the summer/winter solstice. As a result, the generation of solar power by solar light-tracking BIPV system shows 6.7% higher than fix-PV panel system. Meanwhile the generation of solar power by rotating PV system shows 1% higher than fix-PV panel system. Therefore, the solar light-tracking BIPV system will be an effective solution to develop for the zero energy building in educational facility.
