PROBLEM TO BE SOLVED: To provide a technique capable of measuring an I-V curve of a solar battery more accurately and efficiently by making uniform conditions for measuring the I-V curve and suppressing unnecessary measurements.SOLUTION: A photovoltaic power generation system including a power conditioner boosting a voltage of power output from a solar battery module, converting DC power to AC power, and outputting the AC power, measures the power generated by the solar battery module during every acquisition period, sets a value correlating to a maximum value of the generated power measured during a latest acquisition period as a threshold, and measures an I-V curve of the solar battery module if it is determined that the measured generated power is higher than the threshold. |
