POWER GENERATION OUTPUT ACQUISITION METHOD FOR SOLAR CELL MODULE, AND POWER GENERATION OUTPUT ACQUISITION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a power generation output acquisition method capable of acquiring power generation output of multiple solar cells modules efficiently in a short time.SOLUTION: A measurement system comprises: a measurement device 20 for measuring a power generation output property of a solar cell module; a power supply device 24 which applies a current/voltage for generating electroluminescence to the solar cell module; an imaging apparatus 22 for imaging the solar cell module being emitted by generating the electroluminescence; and a calculation device 26 for processing the picked-up image to calculate power generation output. Based on a ratio between a value relating to a light emission strength of a reference solar cell module 10A and a value relating to a light emission strength of the remaining solar cell modules, the calculation device calculates a power generation output value of the remaining solar cell modules or a value corresponding thereto.SELECTED DRAWING: Figure 2
