PROBLEM TO BE SOLVED: To prevent an electric shock accident by realizing an electrically and surely stable state by a simple operation. SOLUTION: A solar battery module 1 is provided with a switching means 4a for output switching between power generating parts 2a and 2b so that the output of the solar battery module can be controlled, or the output open voltages of the generating parts can be divided into further low voltages. In this solar power generating system using the solar battery module 1, the photovoltaic power generating system can be electrically divided by using the switching means into an open state in emergency that the occurrence of earthquake is predicted. Then, normal power generation can be attained by turning the switching means into a make state. |
