PURPOSE: To simplify external wiring between devices constituting a system. CONSTITUTION: A solar power generation system is constituted by an inverter 22 for converting a DC power generated by a solar cell 21 to AC and the equipment of a system interconnection system device 24 which functions as an interface for connecting the solar cell 21 to the inverter 22 and a system power supply 23 and the inverter 22 and the system interconnection device 24 are incorporated into a power distribution panel 25. The distribution panel 25 incorporates the system interconnection device 24 which is connected to the system power supply 23 via an internal system interconnection switch 26 and the inverter 22 connected to each of the system interconnection device 24 and the solar cell 21, a connection cable among such equipment as the system interconnection system switch 26, the system interconnection device 24, and the inverter 22 and a transmission cable for transmitting a measurement signal and control and operation signals are formed as internal wiring, and an external wiring covers only the system power supply 23, the solar cell 21 and the load 27 and the power distribution panel 25. |
