A photovoltaic power generation system includes: a photovoltaic power generation device (1); a power conversion controller (3) including an output control function of converting the DC power obtained by the photovoltaic power generation device (1) into an AC power to obtain a maximum electric power; hydrogen producing means (2) for producing hydrogen using the DC power obtained from the photovoltaic power generation device (1); switching means (4) for making switching electrical connection configuration among the photovoltaic power generation device (1), the power conversion controller (3), and the hydrogen producing means (2); and a control unit (6) for transmitting a control signal to the switching means. A rated output of the photovoltaic power generating device (1) is set to be greater than the rated output of the power conversion controller (3). The control unit (6) controls switching means (4) in accordance with a comparison result between the power generation prediction power W 0 and the output power W 1 of the photovoltaic power generation device (1) or the output power W 2 of the power conversion controller (3), and a conversion efficiency characteristic of the power conversion controller (3). |
