What is a torque tube in a solar tracker?

In a solar tracking system, the torque tube is a critical structural component, especially for single-axis solar trackers. Torque tubes are typically circular, square, pentagonal, octagonal, or D in shape and coated with galvanizing. The torque tube connects all PV module s, ensuring that they all track the sun’s path simultaneously.

What is a torque tube for solar panels?

A torque tube in solar arrays is a horizontal structural element that connects multiple solar panels. It is typically made of high-strength materials like galvanized steel, stainless steel, or aluminum.

Should I install torque tubes in my solar array?

Aluminum, which is lighter and corrosion-resistant, is often used in smaller solar installations where weight is a concern. Installing torque tubes in a solar array might be an additional cost. However, it’s more of an investment that offers excellent returns in the long term.

Who makes luminous and solar tracker torque tubes?

TUSPIPE has rich experience in manufacturing luminous and solar tracker torque tubes using welding robots. The robot joins the torque tube and accessories as required, ensuring that the welding quality and accuracy meet the specified standards.

How do solar trackers work?

Torque tubes have been used in solar tracker designs to handle both bending and torsional forces. Solar trackers point solar panels or modules in the direction of the sun as it moves across the sky. These devices rotate their orientation throughout the day to track the sun’s path and capture the maximum amount of energy.

What is a single axis solar tracker?

Single-axis solar trackers, in particular, rotate the solar panel (s) around a single axis. There are several types of single-axis trackers, including horizontal, vertical, tilted, and polar-aligned trackers. Each of these trackers rotates supported panels about a single axis.
