The paper proposes a new solar position sensor used in tracking, system control. The main advantages of the new solution are the robustness and the economical aspect. Positioning accuracy of the tracking system that uses the new sensor is better than 1 degrees. The new sensor uses the ancient principle of the solar clock. The sensitive elements are eight ordinary photo-resistors. It is important to note that all the sensors are not selected simultaneously. It is not necessary for sensor operating, characteristics to be quasi-identical because the sensor principle is based on extreme operating duty measurement (bright or dark). In addition, the proposed solar sensor significantly simplifies the operation of the tracking control device.
