Solar power generation system

A solar power generation system comprising:

• a plurality of solar cells, or a plurality of solar cells and at least one capacitor, which are connected in series between output terminals;
• an accompanying circuit provided for each of the plurality of solar cells, or each of the plurality of solar cells and each of the at least one capacitor, the accompanying circuit including an inductor and a switching device arranged in series;
• and
• a power generation operating point control device , wherein
• each of the plurality of solar cells or, each of the plurality of solar cells and each of the at least one capacitor, is operable to deliver current to between the output terminals when corresponding switching device is cut off,
• the plurality of solar cells, or the plurality of solar cells and the at least one capacitor, are divided into a plurality of units, of which adjacent units share one of the plurality of solar cells or one of the at least one capacitor, and
• the power generation operating point control device is provided for each of the plurality of units, and is configured to control connection and disconnection of the switching device that belongs to the unit for which the power generation operating point control device is provided so as to optimize power generating capacity of the unit for which the power generation operating point control device is provided.
