The embodiment of the invention provides a positioning system and method for an abnormal photovoltaic module, and belongs to the technical field of power generation. The abnormal photovoltaic module positioning system comprises a data processing device and a plurality of data acquisition devices. The photovoltaic module group string comprises a plurality of photovoltaic module sets, and one photovoltaic module set comprises two photovoltaic module subsets; the data processing device is used for determining whether the state of each photovoltaic module set is abnormal or not based on the two groups of voltage data of the photovoltaic module set; and according to the two groups of voltage data of the photovoltaic module set, determining an abnormal photovoltaic module area in the abnormal photovoltaic module set, and according to the temperature data of the photovoltaic modules in the abnormal photovoltaic module area, determining the positions of the abnormal photovoltaic modules in the abnormal photovoltaic m
