U17A Multi-Point Linkage Actuator for Multi-Row Solar Tracking

One 24V DC Motor Driving Three Actuators for Coordinated Row Adjustment

The TOMUU U17A was developed for multi-point linkage solar tracker systems where multiple actuator points are required along one tracker row. Its mechanical arrangement allows one motor to drive three actuators, providing coordinated movement across multiple support points.

With a rated push and pull load of 20,000N, the U17A was designed for solar tracker structures where a single actuation point may not be suitable for the row layout or load distribution.

One Motor, Three Actuators

The main difference between the U17A and a conventional single-actuator arrangement is its multi-point linkage structure. One 24V DC motor provides the drive for three actuator points positioned along the tracker row.

U17A Key Specifications

*70,000N maximum static load is specified for the 500mm stroke configuration at half stroke.

Installation & Dimensions

The minimum installation dimension of the U17A is based on Stroke + 516mm ±2mm. Because this actuator is intended for a multi-point linkage arrangement, the installation position of each actuator should be evaluated together with the tracker row structure and linkage geometry.

What Should Be Confirmed for a Multi-Row Tracker Project?

A multi-point linkage system cannot be selected only by actuator load. The number and position of actuator points directly affect the linkage arrangement and the force transferred through each actuator.

TOMUU can review these inputs together to evaluate whether a multi-point linkage actuator configuration is suitable for the project.

Multi-Point Linkage for Solar Tracker Rows

The U17A concept was developed for tracker rows using multiple actuator points for east-west tracking. This type of arrangement is especially relevant when the tracker structure requires movement to be distributed across several positions along the same row.

The actual actuator and linkage configuration should be evaluated according to the tracker structure rather than applying one fixed arrangement to every project.
