PROBLEM TO BE SOLVED: To display the amount of generation of an entire solar light generation system using a plurality of power control devices (inverters) by displaying the total value of power that is outputted from the plurality of power control devices. SOLUTION: Solar battery arrays 1a and 1b connect, in parallel, a solar battery string where a plurality of solar battery modules are connected in series. Power collection boxes 2a and 2b are power collection mechanisms for collecting power that is outputted from each plurality of solar battery strings, and are provided with a switcher for switching the connection between the solar battery array 1 a and an inverter 3a, or between the solar battery array 1b and an inverter 3b, a mechanism for verifying the output of the solar battery arrays 1a and 1b for maintenance and inspection, and a non-return mechanism by a diode. The inverters 3a and 3b convert a DC power that is supplied from the power collection boxes 2a and 2b to AC and outputs it to a commercial AC system 7. A signal for indicating the amount of generation of the inverters 3a and 3b is transmitted to a display unit 5 by cables 4a and 4b.
