Wire-Based Solar Tracker with Motion transmission systems for Wind Adaptive Solar Panels

Patentradars sammanfattning

Vaja AB's solar tracker system mounts solar panels on rotatable support members driven by a motor via high-strength wires, with at least one motion transmission system—comprising an extension mechanism such as a tension spring and an optional sacrificial release mechanism—incorporated along the wire's length. The extension mechanism allows panels to rotate passively around a horizontal axis under wind load, reducing mechanical stress without demanding continuous motor intervention. A release mechanism (e.g., shear pin, frangible nut, or magnetic breakaway connector) acts as a controlled failure point to protect costlier components. The design supports multi-motor configurations, variable-strength spring arrays across multiple tracker rows, and computer-controlled motor compensation for spring extension caused by wind.
