<P>PROBLEM TO BE SOLVED: To realize an electric power generation amount monitoring system of a solar cell panel that can reduce electric power consumed by a method and a system for identifying a deteriorated or failed solar cell panel, and that can work even in a state in which the solar cell panel is failed or generates only a very small amount of electric power. <P>SOLUTION: By arranging a power source for a voltage detection circuit and a communication circuit in a serially connected solar cell output unit to supply electric power to the voltage detection circuit and the communication circuit of each solar cell panel, a solar cell panel monitoring system makes it possible to send a centralized monitoring system power generation voltage of a solar cell panel which is failed and cannot generate power via a communication line. <P>COPYRIGHT: (C)2012,JPO&INPIT |
