Abnormality detection method, abnormality detection apparatus, and power generating system using the same.

摘要

It is an object of the invention to accurately detect a defective photoelectric conversion element regardless of the installation place and notify the corresponding information. The above object can be achieved by a power generating system having a solar cell array constituted by a plurality of parallel-connected solar cell strings each consisting of a plurality of series-connected solar cell modules The system includes electrical parameter detection units for measuring electrical parameters in solar cell strings, a comparing unit for comparing the detected electrical parameters mutually, and a warning unit for warning an abnormality on the basis of the comparison result.
