PROBLEM TO BE SOLVED: To provide a power supply system capable of efficiently supplying power from a plurality of existing devices or the like to a load.SOLUTION: A power supply system comprises a fuel cell 60, a photovoltaic power generation part 10 and a power storage device 20 and is configured to supply power to a domestic load 40. In a first mode, a state of preferentially supplying power from the fuel cell to the load is provided. In the case where the photovoltaic power generation part 10 stops generating power and power from a commercial power source 50 and the fuel cell 60 is being supplied to the load and in the case where power from the photovoltaic power generation part 10, the commercial power source 50 and the fuel cell 60 is being supplied to the load, the power storage device 20 is discharged and power of predetermined electric energy is supplied to the load. Thus, electric energy of power supplied from the commercial power source 50 and the fuel cell 60 is made into first electric energy W10 (800 W) which is set as electric energy more than at least a maximum power generation amount of the fuel cell 60. |
