Abstract
A solar power generation device is provided which includes a first DC-DC converter to which an output of a solar battery is input, a storage battery to which an output of the first DC-DC converter is input, a second DC-DC converter that converts a voltage of the storage battery, and a control unit. The control unit changes a duty ratio of the first DC-DC converter so as not to charge the storage battery and changes a duty ratio of the second DC-DC converter so as to set an operating point of the solar battery to a maximum power point, when a value indicating a state of charge of the storage battery is equal to or greater than a predetermined value.
