Abstract
A photovoltaic apparatus includes: a concentrator photovoltaic panel; a driving device configured to change an attitude of the photovoltaic panel; a current detection unit configured to detect an output current of the photovoltaic panel; and a control unit configured to cause the driving device to perform a sun-tracking shift operation when it is determined based on a detection result of the current detection unit that the photovoltaic panel is generating no power during tracking of the sun.
