- the detection unit 24 acquires an IV characteristic curve and a PV characteristic curve (S10), and detects a peak (S12).
- the setting unit 26 identifies the peak with the maximum voltage (S16). If current> threshold (Y in S18), the setting unit 26 sets the peak with the maximum voltage as the operating point (S20). If current> threshold is not satisfied (N in S18), the setting unit 26 sets the peak at which the power is maximum as the operating point (S22). When there are no plural peaks (N in S14), the setting unit 26 sets the peak as an operating point (S24).
- the operating point if the current value at the first peak having the maximum voltage value is less than the threshold value, the operating point is set based on the second peak having the maximum power value. Therefore, the output power can be increased. Moreover, since the output electric power is increased, the power generation efficiency of the solar cell module can be increased. Further, if the current value at the first peak having the maximum voltage value is larger than the threshold value, the operating point is set based on the first peak, so that the occurrence of the hot spot phenomenon can be suppressed.
