Optimized Utility Scale Single Axis Tracker Controller
Working principle:
The torque tube of the single axis tracker controller is arranged
in the north-south direction. And then make the photovoltaic
modules rotate according to the variation of the sun azimuth,
reduce the angle between the sun's direct light and the
photovoltaic modules, which can effectively improve the yield of
single axis tracking system in most area up to 15% to 25%.
Single axis solar tracker includes, mounting bracket for solar panel, horizontal shaft, rotation drive mechanism, wind speed detection device and tracking controller. Single axis solar tracker has one degree of freedom that acts as an axis of rotation.

permits full accessbetween rows and enables flexible, high density
site layouts.
2. Field proven, robust, and reliable tracking systems.
3. Maintenance-free patented polymer spherical bearings. Field tested under harsh environmental conditions to validate their high reliability.
4. Wireless Zigbee communication system between independent rows.
5. Industrial-grade control system based on a micro processor features an advanced wind control software with stow positions for tracker safety.
6. Equipped with GPS to Guarantee the Accuracy of Time
High weather resistance contributes to safe and stable operation between -40℃-70℃. The excellent electromagnetic compatibility design makes the system stable and reliable.
7. Remote Communication, Group Control for Multi-Equipment
Automatically identify the failure, with automatic self-protection and alarm; Quadruple over-current protection ensures the safety of the whole system
8. Customized System Configuration
It can be designed according to customer’s specific requirement.
Functions:
1. High reliability: It can handle freely in the area with serious
electromagnetic interference. Its excellent electromagnetic
compatibility design ensures high reliability operation of the
system.
2. Intelligent wind resistance: It is automatically leveled to the initial position at night. At the same time, the system has a wind load protection interface and supports an external wind speed sensor, which can control the system to enter the maximum wind resistance state of the machine at any time.
3. Power-off memory: There is a backup battery inside the system, which can ensure that the system power-off data is not lost, and automatically enters the running state after power-on.
4. Strong weather resistance: The system uses industrial grade chips and aerospace-grade clock sources to ensure safe and stable operation of the equipment in the range of -40 to +70 degrees without cumulative error.
