Solar Tracker Torque Tubes

The solar torque tube is a key component in tracking solar photovoltaic (PV) systems. It supports the PV brackets and solar panels, connecting the motor on one end and the coupler on the other. Torque tube's primary role is to transfer the motor's torque to drive the rotation of the solar panels.

Since single-row solar PV systems often extend over several dozen meters, strict requirements for torsional and straightness control of the torque tube are essential for synchronized rotation and ease of cleaning.

To ensure strength, rigidity, and corrosion resistance, Torque Tube For Solar Trackers materials like high-quality carbon steels Q355B and Q460B with hot-dip galvanizing or grades S355GD, S450GD, and S550GD with pre-galvanizing or zinc-aluminum-magnesium coating are commonly used.

Additionally, weld quality is rigorously tested through flattening and flaring tests to meet required standards.

Torque tubes are typically circular, square, pentagonal, octagonal, or D in shape and coated with galvanizing. The torque tube connects all PV modules, ensuring that they all track the sun's path simultaneously.
