Photovoltaic power generation system
First Claim
1. A photovoltaic power generation system to charge a battery of a vehicle, including solar cells for feeding an electromotive force to said battery, comprising:
- a display unit to make a remaining level of said battery and an electricity generated by said solar cells visible; and
a charge and discharge control circuit for controlling a display state of said display unit,wherein said display unit comprises a plurality of luminous elements each configured to emit a light beam different in color, while said charge and discharge control circuit is configured to control said display unit so that depending on the remaining level of said battery, at least one luminous element from among the plurality of luminous elements is selected to be lit, and a flickering interval of the selected at least one luminous element is varied depending on the electricity generated by said solar cells.

Abstract
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.
