Solar Torque Tubes

Solar Torque Tube refer to a critical structural component of a single-axis solar tracker.

The torque tube as the mechanical backbone of a utility-scale solar array. It is a long, high-strength structural element—typically circular, square, or octagonal—that supports a row of photovoltaic (PV) modules. Its primary engineering function is to transmit rotational force (torque) from a central motor to the panels, allowing them to track the sun's trajectory with high precision.

Engineering Specifications

• Torsional Rigidity: Must withstand massive twisting forces and wind loads without deforming.

• Material Integrity: Usually made of in-line galvanized steel or hot-dip galvanized steel to resist atmospheric corrosion over a longer lifespan.

• Geometric Precision: Strict straightness tolerances are required to ensure synchronized movement across rows exceeding 100 meters.
