Abstract: A dual-axis solar tracking system comprises a base (110) supporting a gimbal assembly (111) carrying a panel mounting platform (112), rotated by an azimuth drive unit (113) and an elevation drive unit (114), each incorporating a self-locking worm gear transmission (123a, 123b). A shadow-differential sensor cluster (115) comprising a quadrant photodiode array (116) arranged about a central shading gnomon (117) produces a differential shading signal indicative of angular pointing error. A controller unit (118) executes a hybrid tracking algorithm (120) that computes a candidate position from an astronomical position calculation module (119) and continuously refines it using said differential shading signal. A wind speed sensor (121) is coupled to said controller unit (118), which, upon detecting wind exceeding a safety threshold, drives said panel mounting platform (112) to a flat fail-safe orientation thereafter maintained by said self-locking transmissions (123a, 123b) without continued motor energisation, thereby improving long-term tracking accuracy, reducing parasitic power consumption, and reducing structural risk during high-wind events.
