PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system in which an electricity generated by solar cells and a remaining battery level can be checked at once, thus enabling the photovoltaic power generation system to be efficiently operated.SOLUTION: The photovoltaic power generation system 11 is provided to charge a battery 42 of a vehicle and includes solar cells 21a, 21b, 21c for feeding an electromotive force to the battery 42. The photovoltaic power generation system includes LEDs 52, 53, 54 as a display section to make the remaining level of the battery 42 and the electricity generated by the solar cells 21a, 21b, 21c visible. Without taking a trouble to prepare a measuring instrument or pushing a button, a user of the vehicle can immediately check a remaining level of the battery 42 and the electricity generated by the solar cells 21a, 21b, 21c by visually checking a display of the LEDs 52, 53, 54 as the display section, thus enabling the photovoltaic power generation system 11 to be efficiently operated. |
