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. The photovoltaic power generation system is provided to charge a battery of a vehicle and is equipped with solar cells for feeding an electromotive force to the battery. The photovoltaic power generation system includes LEDs to make the remaining battery level and the electricity generated by the solar cells visible. Without taking the trouble to prepare a measuring instrument or to push a button of an indicator, a user of the vehicle can immediately check the remaining battery level and the electricity generated by the solar cells by visually checking the display of the LEDs, thus enabling the photovoltaic power generation system to be efficiently operated. |
