Patent ID: 8352084

Claim:
A solar power generation system comprising: plural electricity generation devices each having a solar panel and incorporating a power conversion apparatus for converting DC output from the solar panel into AC output which is supplied to a commercial power system; a control unit for monitoring the output voltage of the power conversion apparatus, normally performing maximum power follow-up control so that the power conversion apparatus can generate its maximum power, and performing output-suppression control that suppresses the output of the power conversion apparatus when the output voltage becomes higher than a predetermined value; and a measuring unit for measuring the amount of power to be sold from the power conversion apparatus, the amount of power to be bought from the commercial power system, and the amount of generation-suppressed power generated when the output is suppressed; and an watt-hour meter measurement data adjusting unit linked with the plural electricity generation devices via a communication lines; wherein the watt-hour meter measurement data adjusting unit calculates virtual generation-suppressed power amounts that make the burdens of the electricity generation devices even, independent of the actual generation-suppressed power amounts, and calculates the amounts of power to be sold by the electricity generation devices on the basis of the virtual generation-suppressed power amounts.
