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 m...

Photovoltaic industry is a sunrise industry based on semiconductor technology and new energy demand, and the high ground of the future global advanced industry competition. PV mounting system is one of the critical component of photovoltaic power station. As the support system of solar modules, it is a reliable guarantee to maximize the utilization of photovoltaic energy. According to the different materials, mounting structures usually divided into: Ordinary steel structures and new aluminum alloy structures. The mounting structures exported by Kseng every year are mainly in aluminum alloy. The advantages of aluminum alloy solar mounting structure includes: ①.Anti natural corrosion: Aluminum placed in the air forms a dense protective layer of aluminum oxide on top, which prevents further oxidation. ②.Anti galvanic corrosion: When the steel bracket and solar panel in contact, aluminum panel frame is prone to galvanic corrosion, while the aluminum bracket avoids this phenomenon. ③.Keep voltage balance: The excellent electrical conductivity of aluminum, can better conduct the weak current generated by various reasons in the PV mounting system. ④.Easy forming: Aluminum products with different section shapes can be easily obtained by extrusion process with different dies. ⑤.Easy machining: Aluminum profiles can be easily sawed, drilled, punched and folded to the required specifications, and the energy consumption of the process is much lower than that of steel. ⑥.Low temperature resistant: Ordinary steel, especially the welding area, is fragile and brittle in low temperature, while the strength of aluminum alloy material increases.

Distributed photovoltaic power stations are generally built on the residential roof, industrial roof and vegetable greenhouses to make full use of space. Centralized photovoltaic power stations to make full use of abandoned land resources, mostly built in desert and Gobi areas . Similarities between distributed PV power stations and centralized PV power stations: ① Same principle, use solar energy to convert into electricity, and then connect the generated electricity to the grid for production and domestic use. ② Same modules, It is common to use monocrystalline silicon panels or solar films. ③ Use same equipment, which includes inverters, transformer, combiner box etc...... The function of the inverter is to convert the generated direct current into alternating current. The role of the transformer is to convert the inverter to AC voltage boost. The function of combiner box is to gather the DC power of the solar panels and transfer if to the inverter uniformly. Differences between distributed PV power stations and centralized PV power stations: Ⅰ.Different installation site: Distributed photovoltaic power stations are mostly installed on roofs and agricultural greenhouses, mainly in the personnel concentration of north and south China. Centralized photovoltaic power stations are mostly built in desert and Gobi areas, mainly installed on relatively remote and desolate, where the land is relatively cheap. Ⅱ.Different secondary equipment: Distributed photovoltaic power stations are used less primary and secondary equipment because the low voltage grid connection. Inverters are generally wall mounted, It’s easy to install and small in size, transformer are small size as well. Common use of power quality monitoring, anti-island protection devices, etc., equipment requirements and technical parameters are also different according to different regions . Ⅲ.Different transport distance: Distributed photovoltaic is connected to the local grid, there’s little or no loss of line. Replenishment of local power supply for use by local and nearby users. As the higher voltage level, Centralized photovoltaic power station usually has its own substation. Inverters with large size are usually installed in the sub-station room. The booster function is completed by the box transformer. There are more equipment in the booster station. The primary equipment includes station transformer, switch cabinet, various transformers, arc suppression coil, main transformer and so on. The secondary equipment includes microcomputer protection, watt-hour meter, dispatching data screen and so on. Dispatching directly implements centralized management of the power station. At the same time, the station also needs a power control system etc., which is much more complicated.
