PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system including means for measuring electrical parameters (current, voltage, power, etc.) for solar battery strings and sub-arrays constituting a solar battery array, comparing the parameters, and detecting abnormality in the solar battery string or sub-arrays, for providing a technique capable of reducing load accompanying data processing in a measuring data processing personal computer and load accompanying data storage after the processing. ! SOLUTION: The photovoltaic power generation system comprises: measuring means constituted by a plurality of solar battery units and measuring an electrical output value of each solar battery unit; and abnormality determination means determining whether abnormality occurs to each solar battery unit on the basis of a measuring result transmitted from the measuring means. The abnormality determination means includes a ranking unit ranking the respective solar battery units on the basis of magnitudes of |
