Smart Multi-Slew Drive Independent Solar Tracking System

Product Overview

Yingtai Smart Multi-Slew Drive Independent Solar Tracking System is designed for utility-scale solar projects. It supports a maximum system length of 80 m, wind resistance of 60 m/s (per ASCE 7-10), tracking angle range up to ±60°, and N-S slope tolerance options. The system integrates structural, drive, control, terrain adaptability, and weather resilience advantages into one optimized solution.

Core Advantages

Rotary Reducer
Strong performance, durable and long-lasting.

Transmission Shaft
Synchronous drive.

Protective Stow
More secure at 5° to withstand strong winds.

Innovative Electronic Control System
Using algorithms and real-time data to intelligently locate in the safest and most efficient location.

Compatible with Large Panels
Compatible with all new large format modules.

Resilient to Strong Winds

Patented multi-slew drive design distributes forces across multiple points, ensures whole system stability. Certified by CPP WIND, engineered to withstand strong winds.
Individually controlling each string to adapt to any wind load, gathering terrain slope data, identifying wind angles, and employing a four-tier protection mechanism. This ensures autonomous adoption of the safest position in strong winds.

Adaptable to Diverse Terrains

North-south maximum slope 20%, linked or unlinked options are available, optimizing capacity even in constrained conditions.
Multiple foundation options, adaptable to any soil while minimizing the need for earthmoving.
Each row is independently controlled, with an advanced backtracking algorithm. By dynamically responding to the angles and slopes of the terrain, it significantly enhances overall energy yield.

Coping with Severe Weather

Designed based on wind tunnel test data, ensuring stability in high winds and heavy snowfall.
Equipped with advanced sensors and machine learning, the controllers monitor facilities, detect faults, and predict threats.
With wireless communication and backup battery, functionality is maintained during power grid outages.
Automatic snow response uses ultrasonic sensors to detect snow accumulation, adjusting the tracker for self-cleaning and preventing module obstruction.
