PROBLEM TO BE SOLVED: To provide a highly convenient power supply system.SOLUTION: The power supply system includes: a photovoltaic section 10 capable of generating power on sunlight; a distribution board 60 connected to a commercial power supply 200 and the photovoltaic section 10 to distribute power to loads (general loads 110, 110, ... and particular load 120); a stationary power storage device 80 connected to the distribution board 60 and capable of exchanging power with the distribution board 60; and an on-vehicle power storage device 30 connectable to the distribution board 60. When the on-vehicle power storage device 30 is connected to the distribution board 60, so that the on-vehicle power storage device 30 can supply power to the distribution board 60, the distribution board 60 is disconnected from the commercial power supply 200 and the photovoltaic section 10, and all the power from the photovoltaic section 10 is made to flow back to the commercial power supply 200. |
