In solar thermal power plants, sensors are used for precise measurement of angle and position to enable the system to capture the maximum amount of sunlight. The downstream control system receives the required feedback of position, from the sensors, and then adjusts the actual value to the corresponding setpoint. The required angle (or set point) is stored in the controller depending on the time of day and consequently the solar altitude angle. The collectors can assume any position and consequently follow sun movement ideally.

SIKO’s sun tracking products include SIKO translation module ASA510H, SIKO inclinometer IK360, SIKO magnetic sensors MSA501 and MSK5000.   SIKO is a system supplier in position detection, working with customers to provide customer-specific solutions, and ensuring best efficiency at low process costs.   The company is represented in South Africa by INSTROTECH.
