Manufacturing method of shielding plate for concentrating photovoltaic power generation module, concentrating photovoltaic power generation module and concentrating photovoltaic power generation module

摘要

The bent portion is bent so as to rise from each of the four sides of the rectangle of the main plate toward the first surface side. The main plate is provided with a plurality of transmission holes that penetrate from the first surface to the second surface and transmit sunlight toward each of the plurality of power generation elements. The main plate is provided with a first insertion hole that penetrates from the first surface to the second surface and has a size larger than the plurality of through holes.
