From Xining City in Qinghai Province, proceeding along the G6 highway to the west, there are two winding roads to the west of Danghe River. The northwest is the world-famous Qinghai Lake, and the southwest direction is the world's largest and largest single photovoltaic project invested by hydropower in the middle and upper reaches of the Yellow River. Gap Water Complementary has represented the Qinghai Gonghe 100MW empirical base with the highest productivity in the industry.
In the 100MW demonstration base of the Yellow River Hydropower and Qinghai Gonghe, the power station operation and maintenance personnel told the reporter: “By tracking the support, the power generation capacity can be increased by 10% to 40%, and the average power generation capacity can be increased by 30%, depending on the month and the weather. The oblique single axis and the single axis have long items."
It is reported that the project uses the CITIC Boping single-axis tracking system 60MW, oblique single-axis tracking system 20MW. The author consulted the technical person in charge of the project on CITIC Bo. "What is the essence of tracking stents?" They first raised this issue with the author, and then answered: "It's an amplifier."
Regardless of which component or inverter is selected, the tracking bracket will increase the power generation in proportion, so PERC, N-type and other high-efficiency components need to use the “amplifier†of the tracking system to make the advantages more obvious. The person in charge of the technology told the author that the tracking system can maximize the advantages of the two-component system. "The two-sided assembly system should be kept as little as possible. This is a natural problem that we can solve with the stent tracking system."
This is the reason why more and more power stations that have conditionally installed tracking systems in the PV leader project have started tracking systems. CITIC has also just completed the delivery of the 40MW dual-agricultural power plant tracking system and the project is being installed and commissioned.
Battle to raise war
At the beginning of this year, CITIC Group was ranked among the top 10 tracking support companies in the IHS. Before doing tracking support, they are already one of the world's largest manufacturers of photovoltaic fixed supports.
Since 2009, CITIC has been focusing on the bracket industry. Whether it is a fixed bracket or a tracking bracket, it has always been technology-driven. This has also allowed CITIC Bo to stay at the forefront of the market, with more than 70 technical teams. There is no such thing as tracking stents. Thanks to CITIC's strong R&D and testing capabilities, the C&C Certification Center and TUV have issued the only “Accreditation Lab†authorization for the stand-alone company: Data from the CIC Labs laboratory is recognized by the entire industry. Due to its strong technology, only three years have passed.
However, they did not stop in front of their achievements, and they had very early research and development on the tracking system solutions that had been well-known. "But we didn't desperately. We saw the context of the market very clearly. When we started projects, when it was used as a reserve technology, and when we put lots in the market, we all had our own time." Bo is more capable and capable of continuously and steadily researching a technology and pushing it to the market at the right time.
“First of all, from the domestic demand for tracking systems, it is just in the outbreak stage, and the proportion is not high enough.†They explained: “In essence, companies want to survive must be profitable. Many manufacturers only have a single product, but Three years ago, the tracking system's penetration rate was very low. Nowadays, with less and less land resources, leading-edge projects require higher and higher system efficiency, and at the same time, electricity prices are getting lower and lower. Investors have started to develop tracking systems. But this requires us to The R&D personnel of the support companies have invested heavily in. China CITIC Bo added tracking systems from the fixed-support business segment. Good management and control experience over the years first resolved the fact that the quality of production was not uncontrollable, and good cash flow allowed us to fight for protracted battles.â€
At present, the two production lines of CITIC-Boss are fixed and tracked in parallel. “In addition, both domestic and international markets can meet customer needs and have strong anti-risk capabilities. This is why we dare to continue investing and put forward 'Continual improvement, excellence in products, better services, and cost-effectiveness.' "The bottom line is where the slogan is," added Zhou Shijun, general manager of Chinatrust's domestic marketing center. “We are not looking for technology and technology, but we look at R&D and business from the point of view of improving overall power generation and lowering the cost of single-watt generation.â€
Scaffolding scenario solution
“Employing brackets, especially tracking brackets, cannot passively wait for market demand and must take the initiative to attack.†In photovoltaic power plants, the selection of tracking bracket systems with small cost impact has a great impact on power generation.
So you often see the technical staff of CITIC Bo discuss the customized solutions with the design institutes and investors at the project site. The person in charge of CITIC Technology pointed out: “This is not only providing customers with customized solutions that are more appropriate to their use, but also giving us an innovative direction. We also cherish the opportunity to discuss solutions with customers. Because many tracking support companies Without industry support, there are few physical projects and often the design and application links are out of line."
From the system point of view, they believe that the power station needs the tracking system to be able to operate stably and uninterruptedly. For example, if there is too much time for failure, the power generated by tracking the bracket may even be inferior to the fixed bracket. But at the same time, the more sophisticated equipment, the more vulnerable. "Precision" and "stability" seem to be paradoxes, but CITIC Bo proposed to design the backup system to achieve the goal of "never stopping" the tracking stand.
From the system's perspective, they also carried out scene-based classification of the support system and adjusted the details on the site.
“The so-called scenes include such topographic changes as deserts, mountains, and water;
There are also crop types considered when combining with agriculture, whether greenhouses are needed, and local soil suitable crops;
Also pay attention to the details of the height of the support, piling, floating or lifting of the surface project. â€
Wang Shitao, head of the China Academy of Information Research Institute, said, “For example, the design change of 50 cm from the ground and 2 m from the ground is very large. The cost and why it is designed must be taken into account. Most of these changes are carried. It is a scaffold.†He also explained from the use of scene mode analysis why many of the distributed power plants in Guangdong and industrial and commercial roofs chose to be tiled: “The roof resources are scarce, the above should increase the capacity as much as possible, and the power production per tile area may be less However, the owners are more concerned about the total power generation. The best dip angle in Guangdong is 15% to 20 degrees, but tile is selected for more shops."
An excellent bracket system can not only bring additional power generation to the power station, but also bring intuitive economic benefits to customers. In the Tianchang 10MW project, China Unicom adopted a large-span single-axis design, which is also The first application of this product on a global scale. Through the rational layout of the triangular network structure, CITIC expands the distance between each pile from 3.5M to 14M, reducing the number of MW piles from 460 to 176, without pumping, all over water, and large-span sections. Transfer job. “Using this technology, investment in surface project use tracking system is even lower than that of fixed brackets.†The head of CITIC Technology said, “The deeper the water surface is, the more obvious the cost advantage is.†At the same time, in this project, the original is everywhere. Cement piles, no way to cross the boat. "Now it is easy to ship," he added.

Above Generation: Ecotop Runners
Due to professionalism, many investment companies have found CITIC and jointly worked out a bid plan for the leader project. During this process, CITIC Bo also constantly considers the issue of power generation for customers.
"The frontrunners need technological innovation, but I also think that the frontrunners should not be just the leader of a single technology, but the leader of the entire ecosystem." The head of CITIC Technology said seriously: "At this stage, oil and coal have not dried up, so The benefits of photovoltaic power plants must ultimately be ecological benefits."
He first firmly believes that high-quality farmland should not be used as a photovoltaic power station to ensure the red line of 1.8 billion mu of basic farmland. However, in relatively poor and poor farmland, he felt that agricultural light could complement each other. "Of course, we must choose the corresponding food crops, economic crops or medicinal herbs, and adapt them to local conditions.
They are also studying the use of a scaffolding scheme to complement the plan of land reuse for power plant owners. “Many photovoltaic power plants, especially front-runner projects, should consider the issue of land re-use. If there are no other industries, I think that such projects do not really lead the way. Only through photovoltaic power plants can the soil environment be improved and the wasteland rejuvenated. Our goal."
And CITIC Bo really did. In the 140MW power station project of CITIC Boning Xiabaofeng, the original semi-godified land achieved a perfect combination of the support scheme and suitable drought-resistant crops, and the above power generation, and the cultivation of the following agriculture.
This has also made many customers excited and has chosen tracking system solutions. In the first half of this year, the shipments of the CITIC Bo tracking system were 500 MW, and the shipments of fixed brackets reached 1500 MW. The company's PV racks accumulated shipments reached 12 GW. However, CITIC Bo still has a long-term goal: "We still have a lot of room for growth. China's components, inverters, including fixed brackets have already achieved the world's first. Photovoltaic tracking systems can also be."
