Provided is a tracking device that can increase a negative elevation angle of a panel which receives or concentrates solar light, and that can effectively dump dust that has accumulated on the light receiving surface or light concentrating surface of the panel. A sunlight tracking device is provided with a support pillar (2), a panel (1) that is supported by the support pillar (2) and receives or concentrates sunlight, and a drive device (4) that drives the panel (1) so as to track at least one of the altitude or azimuth of the sun. The panel (1) has an opening (3) through which the support pillar (2) can pass. When the panel (1) faces the ground, the support pillar (2) passes through the opening (3). L'invention concerne un dispositif de poursuite qui peut augmenter un angle d'élévation négatif d'un panneau qui reçoit ou concentre la lumière du soleil, et qui peut éliminer de façon efficace la poussière qui s'est accumulée sur la surface de réception de lumière ou la surface de concentration de lumière du panneau. Un dispositif de poursuite du soleil comprend un pilier de support (2), un panneau (1) qui est supporté par le pilier de support (2) et reçoit ou concentre la lumière du soleil, ainsi qu'un dispositif d'entraînement (4) qui entraîne le panneau (1) de sorte à suivre l'altitude et/ou l'azimut du soleil. Le panneau (1) comporte une ouverture (3) à travers laquelle peut passer le pilier de support (2). Lorsque le panneau (1) est orienté vers le sol, le pilier de support (2) passe à travers l'ouverture (3).
