1. A power-supply system comprising:
- a first power-supply device which supplies power externally and includes a first power storage section; and
a second power-supply device which supplies power externally and includes a second power storage section, whereinthe first power-supply device and the second power-supply device, both of which supply power to a stage set used in a first performance, a second performance, and a third performance, and whereinin parallel with setting up the first power-supply device so as to supply power to the stage set used in the first performance, the second power storage section stores power generated by the solar panel connected to the second power-supply device, and whereinat the first performance, the first power-supply device supplies to the stage set a portion of power stored in the first power storage section, and whereinafter the first performance ends and before the second performance to be held after the first performance starts, the first power-supply device supplies power remaining in the first power storage section to the second power storage section, and whereinin parallel with setting up the second power-supply device so as to supply power to the stage set at the second performance, the first power storage section stores power generated by the solar panel connected to the first power-supply device, and whereinat the second performance, the second power-supply device supplies to the stage set a portion of power stored in the second power storage section, and whereinafter the second performance ends and before the third performance to be held after the second performance starts, the second power-supply device supplies power remaining in the second power storage section to the first power storage section, and whereinat the third performance, the first power-supply device supplies to the stage set power stored in the first power storage section.

Abstract
A plurality of power-supply devices, in which power generated by solar energy is stored, are allowed to exchange power among themselves. Power generated by a solar panel connected to a first power-supply device is stored in a power storage section of the first power-supply device. Power supplied by the second power-supply device, which has a power storage section for storing power generated by the solar panel, is stored in the power storage section of first power-supply device. Power stored in the power storage section of the first power-supply device is supplied externally.

3. A power-supply method for using a power-supply system including a plurality of power-supply devices that supply power to a stage set used in a plurality of performances, each of the plurality of power-supply devices having a power storage section for storing power generated by a solar panel, the method comprising:
-
in parallel with setting up the first power-supply device, which is one of the plurality of power-supply devices, so as to supply power to the stage set used in a first performance that is one of the plurality of performances, storing power generated by the solar panel into the power storage section of the second power-supply device, which is one of the plurality of power-supply devices and different from the first power-supply device; at the first performance, supplying to the stage set a portion of power stored in the power storage section of the first power-supply device; after the first performance ends and before a second performance to be held after the first performance starts, supplying power remaining in the power storage section of the first power-supply device to the power storage section of the second power-supply device; in parallel with setting up the second power-supply device so as to supply power to the stage set at the second performance, storing the power generated by the solar panel into the power storage section of the first power-supply device, at the second performance, supplying to the stage set, using the second power-supply device, a portion of power stored in the power storage section of the second power-supply device; after the second performance ends and before a third performance to be held after the second performance starts, supplying, using the second power-supply device, power remaining in the power storage section of the second power-supply device to the power storage section of the first power-supply device; and at the third performance, supplying to the stage set, using the first power-supply device, a portion of power stored in the power storage section of the first power-supply device. - View Dependent Claims (4)
