This thesis is based on the research and experiment of the optimal efficiency generation of electric power. The research and experiment were conducted to search the optimal generation of electric power from a specific amount of solar energy from Photovoltaic Power System with a solar position tracker were used. The changes in the array angles and spacing of the PV Module were also taken into account as well. Here are the findings and the conclusions. First of all, based on experiment using the various anglers, the efficiency generation of electric power increased to a maximum of approximately $12{sim}17$[%] more at the PV module inclination angle of 30[$^{circ}$] than at the inclination angles of 20[$^{circ}$] and 40[$^{circ}$]. As a result, we have found that installing the PV module inclination at the angle of 30[$^{circ}$] brought about the most efficient conversion effect of the Photovoltaic Power System. But, when the solar cell is installed on a roof or rooftop where snow builds up, it is the most appropriate to install the solar energy at an 35[$^{circ}$] angle so that snow slides down and not build up on the module.
