KSENG KST solar tracking photovoltaic brackets

Mar 21, 2023


In the early stage of photovoltaic development, PV brackets are mostly fixed structure, It's simple and low cost. With the removal of subsidies, the demand for power station profitability and efficiency is increasing, and the tracking bracket is becoming more and more important to the market.


In the global photovoltaic market, the Middle East uses more than 80% of the tracking bracket, the United States about 80-90%, Europe about 60%.  Among them, the south of France and Spain have flat terrain and sufficient light resources, which is very suitable for tracking bracket. Compared to the fixed braket, the tracking bracket can increase power generation by more than 15%. The proportion of Central African and North African markets also exceeds 60%.


At present, the ratio of PV tracking bracket and fixed bracket is close to 4:6 in global market, It's expected that by 2025, the ratio will be 5:5, or even more. But in China, the figure is less than 10 percent.


In order to follow the development of the times,Kseng launched a new product line of solar tracking systems in early 2021. KST series includes: KST-1P One Portrait Horizontal Single-axis Tracker, KST-2P Double Portrait Horizontal Single-axis Tracker, KST-2PM Multi-drive--double Portrait Horizontal Single-axis Tracker. Compared with fixed bracket, tracking bracket has higher requirements in both software and hardware. Therefore, the following four points need to be made:


1.Smart AI algorithm


Intelligent control system. The biggest difference between the tracking bracket and the fixed bracket is that the tracking bracket has a unique tracking control system, which not only protects the tracking bracket, but also tracks the sunlight according to its location. At the same time, self-learning optimization and adjustment tracking should be carried out according to different topography, installation error, weather and season, so as to ensure higher power generation. KST series uses "astronomical algorithm + closed-loop control" and "AI algorithm" to realize intelligent tracking, maximize the power generation of the PV power station.


2.Passed CCP wind tunnel test



Structure stability. Compared with the fixed bracket, the frequency and damping ratio of the tracking system is lower, so the structural design has higher requirements for the stability. By cooperated with CPP Wind Engineering, Kseng combined with the frequency and damping ratio characteristics of the KS-tracker system, studied the results of resonance, flutter, gallop and torsional divergence of the system, analyze the influence on the system operation process and the instability characteristics.


3. Adapt to 210mm modules


With the continuous updating of modules, as an important link in the PV industry chain, now the tracking system has fully entered the era of 210mm modules, with seamless support and collaboration, more mature industrial chain and more complete ecology.


4.Quick maintenance


KST tracking system equipped with driving mechanism, motor modular design, which reduce maintenance cost, improve maintenance efficiency, also adopt multi-point drive scheme, multi-point electric interlocking ring protection, improve the fault monitoring. No special tools, one-person maintenance.


Currently, KST tracking system can increase the power generation by about 15% to 30% with the combination of excellent hardware and software systems. Among them, the KST-2PM can reduce the amplitude of components by 50%, reduce the force on the spindle by 50%, reduce the force on the driving column by 50%, and reduce the torsion Angle of the spindle by 50%, so that the frequency and damping ratio of the system can be significantly increased, and the wind resistance of the system can be better improved.


We believe that through the efforts of Kseng tracking team and the excellent data of KST series products, we can win the favor of market and customers. We will provide high quality products and thoughtful service for every customer. Kseng products, your best choice.
