Abstract
In order to provide an evaluation apparatus that is capable of measuring the performance of a photovoltaic power generation system accurately while using simple equipment outdoors using sunlight, there are provided a plurality of illumination intensity sensors disposed in the vicinity of the photovoltaic panels, and an evaluator that is connected to a PCS and to the sensors, and evaluates the performance of the photovoltaic power generation system based on outputs from each of these, and the evaluator includes an output acquisition unit that acquires an output of the photovoltaic panels from the PCS, a consistency degree calculation unit that calculates a degree of consistency in illumination intensity measurement values measured by the sensors, and a determination unit that, when the degree of consistency is within a predetermined permissible range, determines that the output of the photovoltaic panels acquired by the output acquisition unit is a true value.
