PROBLEM TO BE SOLVED: To provide a system-interconnection solar power generation system which allows snow-melt operation. SOLUTION: With a signal coming in from the outside, an operation mode switching part 707 stops a system-interconnection operation control part 80 to select a snow-melt operation control part 710. The snow-melt operation control part 710 causes a short circuit with a diode 701 for preventing back flow for to connect a power distribution system 78 to an inverter 72. Here, a main circuit is inserted with a high-resistor 709 to suppress overcurrent. Thus, snow-melt operation is performed without applying loads on a solar cell. |
