PROBLEM TO BE SOLVED: To easily identify the power generation derivation of the amount of charge, even when charging from a power system where the commercial power and the renewable energy power are mixed.SOLUTION: A server device 70 comprises: an I/O port 71 for receiving each information of reservation time, reserved amount of power supply, and actual amount of power supply from a photovoltaic power generator 10, and for receiving each information of reservation time, reserved amount of power supply, and actual amount of power supply from a charger 50; and a control unit 73 for calculating the actual amount of the photovoltaic power generator 10 by correlating the actual amount of power supply of the photovoltaic power generator 10 and the actual power demand of the charger 50 every unit time, when the actual amount and the actual power demand correspond to each other, and adding the actual amount of power supply of each unit time thus correlated to the actual power demand of the charger 50, after completion of charging. |
