TrinaTracker Releases White Paper on Spherical Bearing Component Reliability and Advantages

CHANGZHOU, China, Sep 7th, 2021 -- TrinaTracker, a leading tracker manufacturer and business unit of Trina Solar Co., Ltd. (SHA:688599), has released a white paper entitled "TrinaTracker Spherical Bearing: Unique Three-Dimensional Patented Component”. The document highlights the advantages of the spherical bearing’s unique geometric design through rigorous testing and long-term outdoor reliability.

The white paper describes the advantages of spherical bearings over conventional cylindrical bearings, demonstrated by numerous tests in real installations.

TrinaTracker, always at the forefront of solar industry innovation and technology, designed and implemented a spherical geometry bearing, adding significant value to solar plants. Its three-dimensional articulation improves terrain adaptability and eliminates risks of misalignment and additional forces that create extra friction. Additionally, the assembly of spherical bearings reduces installation times and costs, and does not require any maintenance during the operation phase of the installation.

According to the white paper, the spherical bearing has proven reliable over more than ten years and in over 6 GW of assembly. 

An example of its long-term efficiency is "Zuera," the 11 MW plant installed in Zaragoza (Spain), where the first spherical bearings were assembled. Since the interconnection of this PV plant in 2008, no cases of bearing failure have been reported. 
Jason Duan, Head of the tracker business unit at Trina Solar said: "TrinaTracker’s patented three-dimensional Spherical Bearing, unique to our Agile 1P and Vanguard 2P series, meets the company's objective of increasing our clients' return on investment by lowering BOS cost and guaranteeing reliability during the project lifecycle. No failure is reported regarding TrinaTracker spherical bearings since they were first assembled more than a decade ago."
