To continuously track sun throughout the day, AEDesign’s Sundish uses dual axis tracking. A rotary actuator is used for azimuth rotation and a linear actuator for elevation, and both systems movement are monitored and controlled by a sophisticated control system. The PLC based control system of Sundish can track sun with a precision of 0.01 degree in both azimuth and elevation axis. It uses a time-position based algorithm and a sun sensor to determine the position of sun, and then employs non-backlash actuators equipped with precision encoders to point the Sundish towards sun. It has a self- diagnostic system to check its functionality at the start of each day and can communicate with other devices over RS-485 Modbus protocol.

CSP technologies show a lower degradation over the life of the system and on a daily basis, give a longer peak period of electricity generation compared to PV systems. See graph.
