Abstract In this paper, we analyze the economical efficiency of photovoltaic generator, which is widely used in low-voltage customer, and formulate the equations. The economical efficiency analysis results compare the average monthly power consumption per household and the power usage after solar panel installation based on various information provided by the KEPCO and the Korea Meteorological Administration. The output of solar panel is more economical with higher solar radiation and sunshine. In addition, as the cooling demand increases, the power consumption increases, so the economical efficiency of photovoltaic generator increases. Therefore, this paper proposes an information on break-even point for solar panel installation in low-voltage customer using the economical efficiency result of photovoltaic generator by year.
