PROBLEM TO BE SOLVED: To effectively use electric power obtained by a solar energy generating element. SOLUTION: A power supply system includes the solar energy generating element 1, a DC-voltage transforming means 2 for transforming the DC power obtained by the solar energy generating element 1, and a DC transmission channel 4 for directly transmitting a DC output from the DC power transforming means 2 to a DC power consuming load 3. Accordingly, the number of power transformations is reduced as many as possible to eliminate power loss by transformation. COPYRIGHT: (C)2011,JPO&INPIT
