Patent ID: 7612283

Claim:
A solar power generation system comprising: a plurality of solar cells formed on a common conductive substrate; a plurality of DC/DC converters which are connected to said solar cells, respectively, to boost voltage of DC power output from the connected solar cells; and an inverter which converts DC power output from said plurality of DC/DC converters into AC power, wherein each of said plurality of DC/DC converters comprises first and second input terminals and first and second output terminals, wherein each of said solar cells comprises a first electrode electrically connected to the common conductive substrate, and a second electrode electrically connected to the first input terminal of one of said plurality of DC/DC converters, wherein the second input terminal and the first output terminal of each of said plurality of DC/DC converters are electrically connected to the common conductive substrate for connecting said plurality of DC/DC converters in parallel electrical relation, and wherein the second output terminal of one of said plurality of DC/DC converters is connected to the second output terminal of another one of said plurality of DC/DC converters, wherein said inverter has an insulating transformer to insulate between an input and an output of said inverter, and wherein a connection member which electrically connects said plurality of DC/DC converters to said inverter is grounded.
