Abstract

The invention relates to a tracking system (1) for a solar installation, in particular a thermal solar collector or a photovoltaic module, comprising a stationary bearing (10) of a shaft (20) that can rotate with respect to the bearing (10), on which the solar installation (3) is disposed, and a drive unit (30) for rotating the shaft (20) relative to the bearing (10). The tracking system is characterized in that the drive unit (30) comprises a first and a second actuator (31, 32) that can be actuated such that a drive disc (21) rotationally fixed to the shaft (20) can be clamped or released by means of a longitudinal displacement of the first actuator (31), and a displacement of the first actuator (31) tangentially to the drive disc (21) can be brought about by means of the second actuator (32). A rotation of the shaft (20) can thus be brought about by the drive disc (21) clamped by means of the first actuator (31).
