PROBLEM TO BE SOLVED: To provide a technique for achieving improvement of determination accuracy in a photovoltaic power generation system.SOLUTION: The photovoltaic power generation system comprises: a first detection section 6 for detecting an electrical output value of a power conditioner; a second detection section 7 for detecting an electrical output value of each solar cell unit; and abnormality determination means 9 for determining abnormality of the solar cell unit on the basis of the respective detection values detected by the first detection section and the second detection section. The abnormality determination means includes: a first output determination section for determining whether or not a first output value detected by the first detection section is within a stable output range determined within a predetermined range from rated power of the power conditioner; a second output determination section for determining whether or not a second output value detected by the second detection section is within a normal output range determined within a predetermined range from rated power of each solar cell unit; and an abnormality determination section for determining abnormality of the photovoltaic power generation system on the basis of a situation in which the first output value is within the stable output range and the second output value is not within the normal output range.SELECTED DRAWING: Figure 1 |
