Solar power generation module and light-concentrating solar power generation system

摘要

In the present disclosures, heat from solar cells and the like arising when receiving light can be cooled by a cooling body (103) being provided in a manner so as to cover the entire back surface of a solar cell assembly (102) to which a plurality of solar cells (120) are rectangularly arranged. The cooling body (103) is an integral cast body having a coolant duct (123) inside, and so is robust with respect to heat shock in situations such as when suddenly hit by sunlight, and can reliably handle high temperatures resulting from a level of light concentration that is increased by around 800-2000 times.
