Abstract:
In order to provide a system which detects and classifies abnormality in a solar battery even during power generation, an output voltage and an output current of the solar battery during power generation are detected, and a solar battery characteristic equation and a threshold value for detecting an abnormal state are calculated using the detected voltage value and current value and the measurement data of an external environment measurement unit. The kind of abnormal state of the solar battery is classified using the calculation result of the characteristic equation and the threshold value.
