Solar Tracker Bearing is a high-performance bearing solution specially designed for solar photovoltaic tracking systems. Engineered with advanced materials and optimized structure, it ensures smooth rotation, high load capacity, and long-term maintenance-free operation, making it a critical component for accurate and reliable solar tracking. High Load Capacity Designed to withstand heavy static and dynamic loads from PV modules, wind, and snow, ensuring stable operation of large-scale solar trackers. Maintenance-Free, Self-Lubricating Design Made with advanced self-lubricating materials, eliminating the need for regular greasing and significantly reducing operation and maintenance costs. Excellent Environmental Resistance Resistant to UV radiation, corrosion, high temperatures, dust, and humidity, suitable for deserts, coastal areas, and other harsh outdoor environments. Lightweight and High-Strength Structure Aluminum alloy housing reduces system weight while maintaining high mechanical strength, improving tracker responsiveness and overall system efficiency.

A Solar SCADA System (Supervisory Control and Data Acquisition) is an advanced digital platform designed to monitor, control, and optimize solar tracker systems in real time. Powered by edge computing and intelligent communication through the NCU (Network Control Unit), CloudSCADA provides operators with a centralized “digital cockpit” for managing solar power plants efficiently from anywhere in the world. Unlike traditional monitoring tools, this system integrates real-time control, historical data analytics, meteorological linkage, and third-party system compatibility, making it a critical solution for utility-scale solar farms and distributed PV projects. Standardized Data: Exportable and Integrable into Your SCADA System We understand the value of data assets. CloudSCADA is not just an independent monitoring platform, but an open ecosystem node:

The Solar Tracker Network Control Unit is the core control and communication hub of the solar tracking control system, ensuring safe, reliable, and precise operation of the entire tracking field. It plays a critical role in system coordination by integrating tracking controllers (TCUs) and the SCADA monitoring platform into a unified, intelligent control architecture. The NCU communicates wirelessly with all TCUs in the field to collect real-time operating data, including tracker position, status, and fault information. It supports both individual and group control of TCUs, enabling flexible operation strategies for different tracker rows, zones, or plant layouts. Meteorological data acquired from environmental sensors can be distributed to each TCU in real time, ensuring fast and coordinated responses under changing weather conditions.

The DC-powered Solar Tracker Controller is an intelligent control device It can be directly powered by a DC source, such as PV modules or batteries, offering greater system independence and flexibility where AC power is unavailable. Based on an accurate solar position calculation model, the controller uses time, geographic location data, and real-time angle sensor feedback to achieve high-precision closed-loop control. This ensures that PV modules consistently operate at the optimal solar incidence angle, maximizing overall energy yield. Key Advantages DC Power Supply Design Supports power from PV modules or battery systems, ideal for distributed projects, remote areas, and locations without grid power. High-Precision Smart Tracking Algorithm Time-based control combined with angle sensor feedback eliminates cumulative errors and ensures stable, accurate solar tracking.

GF-AC-V2 (AC-POWERED) Reliable AC-powered unit ensuring stable operation for centralized plants. Designed for large-scale PV tracking systems, the AC-powered controller uses an external AC supply for stable operation. It features high-precision closed-loop solar tracking, comprehensive protection functions, and strong reliability, making it ideal for centralized and utility-scale solar power plants. The AC-powered Solar Tracker Controller is a high-performance control unit designed for large-scale and centralized photovoltaic tracking systems. It is directly powered by an external AC power supply, eliminating dependence on module-side power and ensuring excellent system stability and reliability.
