Disclosed are an electricity control device, an electricity control method, and an electricity supply system, which are capable of controlling such that operating maxima of solar cells and other electricity generating elements are maintained, and of avoiding electricity losses. An electricity control device comprises an electricity path switch unit (32) capable of connecting to a plurality of electricity generating elements (20-1, 20-2), and a voltage transformer unit (31) that transforms the voltage level that is electrically generated with the electricity generating elements and that is supplied via the electricity path switch unit (32). The electricity path switch unit (32) further comprises a first connection switch function that switches between connecting the plurality of electricity generating elements in series or in parallel, and a second connection switch function that switches whether to connect or disconnect the electricity generating elements that are connected in series or in parallel upon the input side of the voltage transformer unit. |
