PROBLEM TO BE SOLVED: To reduce the power consumption of a whole system substantially by a method wherein, among respective power generating units, the units which are not generating power are stopped to eliminate the power consumption of the units. SOLUTION: Respective power generating units 2a-2n are operated by power obtained by the respective solar cell panels 11 of the power generating units 2a-2n. AC voltages outputted from the respective power generating units 2a-2n are introduced to a linkage control board 5 through a power line 3 while the respective power generating units 2a-2n are monitored by a monitoring device 6, and the AC voltages and an AC voltage supplied by a commercial power supply 4 are linked with each other and supplied to a load. |
