Abstract:
A solar power generation system includes a solar module, a power converter, and a control device. The power converter is configured to control an output voltage of the solar module such that the output voltage matches a target output voltage. The control device is configured to determine a lower limit value of the target output voltage based on the following general formula. V TL ( I rr , T ) = V OC ( I rr , T ) · n - 1 n - V BD ( T ) - α ( 1 ) In the general formula, Irr denotes a used light intensity, and T denotes a temperature. VTL(Irr, T) denotes the lower limit value of the target output voltage. VOC(Irr, T) denotes an open-circuit voltage of the solar module. The number of the solar cells connected in series is denoted by n. VBD(T) denotes a positive value of a reverse breakdown voltage of one solar cell. A tolerable error is denoted by α.
