Beschreibung
Zusammenfassung:	A solar power generation system includes a string, an inverter, a first shutoff device, and a second shutoff device′. The string includes a plurality of solar cell modules connected in series. The first shutoff device cuts off the string and the inverter in response to a first control signal from the inverter. The second shutoff device cuts off a solar cell module group including one or more among the plurality of solar cell modules and either another solar cell module or the inverter in response to a second control signal from the first shutoff device. The second shutoff device includes a first switching unit that includes a first open and close unit and a first semiconductor switching device connected in parallel with the first open and close unit. The first semiconductor switching device is turned ON before the first open and close unit is operated.
