PROBLEM TO BE SOLVED: To obtain a solar power generation controller, capable of adding changes in power generation environment, such as amount of solar radiation, and performing the quick maximum power point tracing control. SOLUTION: Output voltages W1, W2, and W3 in operating voltages V1, V2, V3 (V3<V1<V2) are obtained successively (steps T1-T13). When a first condition (W1>W2 and W1>W3) or a second condition (W1<W2 and W1<W3) is satisfied (steps T14, T16; YES), this voltage is returned to the voltage V1. When the first and second conditions are not satisfied and a third condition (W2>W1) is satisfied (a step T17: 'YES'), the voltage is increased to the voltage V2 (step T18). When the third condition is not satisfied (the step T17: 'NO'), the voltage is decided to the voltage V3 (the step T1). |
