NOVELTY - The circuit arrangement includes two photo-sensitive sensors (10; 11) selectively or simultaneously connected with an electronic control (7) which switches a servo-motor (9) over a pulse-controlled regulation (8), in such way, that the solar panel (1) is turned over a shaft (13) in an east-west direction. A timer (15) is arranged between the electronic control and the motor regulation, in such way, that a turning of the solar panel around defined angle segments results over the motor in fixed time intervals, if no pulses are provided by the sensors.    USE - Especially for photo-voltaic module, e.g. in small, mobile stations, such as weather station, or mountain hut.    ADVANTAGE - Enables guiding of solar panel, even if no direct radiation falls on photo-sensitive sensors.    DETAILED DESCRIPTION - The circuit arrangement guides solar modules, especially photo-voltaic modules, which are held respectively vertically to the angle of incidence of the solar radiation, on a panel tilting around its horizontal axis, and revolving between two fixed points around its vertical axis. The turning of a vertical panel support results through pulses of at least one photosensitive sensor and the regulation of an electric motor. Two photo-sensitive, reciprocally shaded sensors (10; 11) are selectively or simultaneously connected with an electronic control (7) which switches a servo-motor (9) over the pulse-controlled regulation (8), in such way, that the solar panel (1) is turned over a shaft (13) in an east-west direction. The electronic control is connected over the regulation with the motor, if a sensor lies in the shadow, and the second sensor in the area of the solar radiation. The connection for the motor regulation is interrupted, if both sensors are in the area of the solar radiation, or if both sensors receive no solar radiation. A timer (15) is arranged between the electronic control and the motor regulation, in such way, that a turning of the solar panel around defined angle segments results over the motor in fixed time intervals, if no pulses are provided by the sensors.
