Abstract
A solar power generation system includes a string, an inverter, a first shut-off device, and a second shut-off device. The string includes a plurality of solar cell module groups. The first shut-off device is connected to a first electric path. The second shut-off device is connected to a second electric path. The first shut-off device cuts off the connection between a plurality of solar cell module groups connected to the first electric path in response to a first control signal. The second shut-off device is driven by the power supplied from the first shut-off device, and cuts off the connection between a plurality of the solar cell module groups connected to the second electric path in response to a second control signal. The first shut-off device includes a first semiconductor switching device and a first open-close unit connected in series to the first semiconductor switching device.
