Abstract: This inspection system for a concentrator photovoltaic apparatus includes: a module; a tracking mount configured to track the sun, the tracking mount having mounted thereto an array formed by assembling a plurality of the modules; an inverter apparatus to extract a direct-current power generated by the array, convert the direct-current power into an alternating-current power, and output the alternating-current power; and an imaging apparatus being positioned between the sun and the array tracking the sun, the imaging apparatus taking an image of the array from a direction orthogonal to a surface of the array. While the array is tracking the sun and is causing sunlight to be concentrated on the cell, the inverter apparatus produces a state where extraction of a power from the array is restricted, to cause the cell to spontaneously emit light, and the imaging apparatus takes an image of the emitted light of the cell.
