SHADING DEVICE OF SOLAR CELL MODULE, SOLAR CELL MODULE, PHOTOVOLTAIC POWER GENERATION SYSTEM AND SHADING METHOD OF SOLAR CELL MODULE

摘要

PROBLEM TO BE SOLVED: To provide a shading device of solar cell module, capable of suppressing power generation of a solar cell module when necessary while solar light is being made incident without degradation in a photoelectric conversion efficiency at normal power generation.SOLUTION: The present invention comprises: a shading sheet 2 covering light-receiving surfaces of solar cell modules 21, 23 each having a photoelectric conversion part for converting solar light into electric power for shading; a housing part 3 for housing the shading sheet 2. The shading sheet 2 discharged from the housing part 3 covers the light-receiving surfaces of the solar cell modules 21, 23 to shade the light incident on the light-receiving surfaces of the solar cell modules 21, 23.SELECTED DRAWING: Figure 6
