On November 3, 2020, Trina Solar released the Supreme King Kong Vertex S series modules to the world, officially opening a new era of high-power modules for distributed photovoltaic applications. At the same time, Trina also launched the seventh-generation original photovoltaic system Electric King Kong and Tianyuan TSE1.0 system. So far, with modules as the core, from system to ecology, Trina Solar’s new photovoltaic ecosystem has taken shape.
Looking back at Tianhe’s distributed development road, in only 4 years, Tianhe has realized the original system from scratch, continuous iteration, and established household, distributed professional brands-Tianhe Fujia and Tianhe Lantian. After the “531” in 2018, most of the companies that once swarmed the household market quickly retreated, and Tianhe is one of the few companies that still stick to it. It is with this resilience that Trina Solar finally ushered in its distributed photovoltaic era.
210 small-size components, born for distributed
With the support of 210mm and 182mm large-size silicon wafers, the power of photovoltaic modules has reached a new stage of 500W+ and 600W+. However, the application scenarios of such high-power modules are large-scale ground power stations. There are few high-power modules that can be applied to distributed projects in the market. Trina Solar released 400W+ high-power based on 210mm large silicon wafers on November 3 Components formally fill this gap.
Dr. Zhang Yingbin, Head of Global Product Strategy and Marketing of Trina Solar, said, “As early as the launch of 500W modules, Trina had already made it clear that 210mm modules could be used in the distributed market. Today, He has officially implemented its original plan.” Zhang Yingbin introduced that, unlike large ground-based power stations, household and distributed photovoltaic projects are subject to roof load-bearing and manual handling restrictions, and have special requirements for the length and weight of the modules. Most countries and regions in the world require that the length of the module is less than 1.8m and the weight is less than 23kg.
Based on the above two “hard” conditions, the Trina Supreme Xiaojingang Vertex S series modules combine 210mm batteries, multi-busbar technology, non-destructive cutting and high-density packaging technologies, so that the module length is controlled at 1.75m and the weight is 21kg. Adapt to various types of rooftop distributed projects. At the same time, the product has the characteristics of “small size and big energy”, the maximum power of the module is 405W, and the maximum conversion efficiency is 21.2%.
In terms of current and voltage design, Zhang Yingbin said, “Previously, the Tianhe 210 modules for large-scale ground projects adopted a low-voltage, high-current design to increase the total power of each string. In distributed projects, the roof area is limited and the modules are not High-current design is required. Through the application of three-slice technology, the short-circuit current of the 405W module of the Supreme King Kong is only 12.34A and the open-circuit voltage is 41.4V, which can be flexibly adapted to most inverter products on the market.”
On top of the product “selling point”, the Trina Supreme Xiaojingang series components also have added value, 25-year power warranty, 15-year product warranty, and extended warranty on customer demand. In addition, this series of products have different appearance designs to choose from, the black frame + black back plate and ultra-fine grid line design are more ornamental.
In addition to the above-mentioned “powerful” product advantages, Trina Solar has also provided sufficient capacity guarantee for the Supreme Xiaojingang components. Compared with ground-based power stations of the hundreds of megawatts and gigawatts, the distributed scale is only at the megawatt or even kilowatt level. For many years, whenever there is a rush to install, distributed projects are always “abandoned”, and component orders are given priority. Ground power station. “In order to get rid of this predicament, Trina Solar has opened up a new production line for the Supreme Diamond Components, which will give customers peace of mind.” According to Zhang Yingbin, the Trina Supreme Small King Kong module will be mass-produced in January 2021. The production capacity for that year is expected to be 5GW, 10GW in 2022, and 15GW in 2023.
Carry the original system to the end
As of the third quarter of 2020, my country’s new installed capacity of distributed photovoltaics is 8.66GW, and the total annual total is expected to exceed 10GW, and households account for about 7GW. Distributed photovoltaics ushered in a real development year. According to Zhang Bing, vice president of Trina Solar and president of Trina Smart Distributed Value Group, “Behind such dazzling results is the joint efforts of colleagues who have been optimistic about the distributed market and optimized products carefully for many years.”
Zhang Bing said that since the first original system was launched in 2016, Trina has believed that the development of distributed photovoltaics requires service commitments and guarantee commitments directly to end users. “Tianhe has been guiding the industry in this direction for many years. If the company only sells one product and does not provide services to end users, let some distributors who only have the ability to install and deliver but cannot provide long-term service capabilities to assume their responsibilities. I am afraid it will be difficult for the industry to move towards healthy development.”
TRW’s worries are not unfounded. After the “531” in 2018, the household and distributed photovoltaic markets have been hit hard. Most of the dealers who have flocked into the market “run off” and “withdrew”, leaving many orphaned power stations behind. There is no way for users to appeal. At this time, the value of the original photovoltaic system is highlighted. Zhang Bing said, “After the baptism of 531, what remains is truly committed to continuous promotion and development of distributed enterprises. Users have also begun to think about value, paying more attention to the electricity cost of photovoltaic power plants throughout the life cycle, rather than initial investment. cost.”
From the perspective of the iterative history of TRW’s original system, since the launch of the first-generation original system in 2016, Tianhe’s original system has been iterated one to two times a year. The electronic diamond system launched on November 3 is The seventh generation original system. Zhang Bing said, “Almost every original generation system in the past adopted the most advanced products and technologies. This is also what Trina has always emphasized to use the best products as original systems.”
According to Wang Yong, the person in charge of Tianhe Fortune Cloud, the E-king Kong photovoltaic system solution can fully cover the application of 400W+, 500W+, 600W+ ultra-efficient modules, which is another big step for the original Tianhe system. Except for 210 core components, TRW’s original inverters all use 4G network to collect information, which is more stable. The bracket chooses pre-galvanized aluminum-magnesium material for longer service life. In the configuration of auxiliary materials, the choice of copper and aluminum joints can reduce the failure rate by 8%. The characteristics of “multiple installations, more power generation, more reliability, and more convenience” make the electric diamond series a new benchmark for photovoltaic original systems.
As it is said that a single tree cannot become a forest, the development of distributed photovoltaic still requires the joint efforts of more colleagues. Zhang Bing said, “With the development of the distributed market and the improvement of user awareness, the original system has grown from a niche product to a mainstream product. Tianhe has always maintained an open mind and looks forward to more companies on the road to the original system. ”
Build a new photovoltaic ecology
If the Supreme King Kong components and the electric King Kong system are aimed at increasing the value of hardware products, the Tianyuan TSE1.0 system is an innovative upgrade of TRW’s software system. Zhang Bing believes, “With the increase in user awareness in the distributed market and the intensification of market competition, there is room for enterprises to innovate in hardware, but it will become more and more difficult. Therefore, in addition to photovoltaic systems, distribution-oriented Market enterprises need to develop a variety of new application scenarios.”
Zhang Bing further explained, “For example, the smart photovoltaic garage SPVC released by Trina is one of the new application scenarios. It includes photovoltaic power generation, power storage, power sales, charging and other links. The entire system cannot be separated from data. Support and intelligent management are impossible to be assembled under this system.”
With the further development of digital and Internet of Things technology, the ecological process of distributed photovoltaics is also greatly deepened. How to build a platform that can connect the operations of various underlying modules in the distributed photovoltaic ecosystem is the key to the leap-forward development of the photovoltaic industry. The Tianyuan TSE1.0 system launched by Trina Solar fully covers the whole cycle of distributed photovoltaic projects from investment to construction, from delivery to profitability, and makes the photovoltaic ecology more sound. Zhang Bing said, “Tianyuan TSE1.0 system, like ios and Hongmeng systems, brings users’ consumption experience to a new stage.”
It is understood that Tianyuan TSE1.0 system includes TSS sales delivery system, TSD distribution business system, TSG gold steward platform, TSF financial service system, and serves the full life cycle of distributed photovoltaic business with digital and intelligent services. On top of the underlying systems, the Tianyuan TSE1.0 system can also be expanded and connected to more applications and new ecosystems. “For example, in the era of comprehensive photovoltaic parity, electricity market-based trading will become the norm. At this time, a digital trading system is needed.” Zhang Bing introduced.
Just as the household photovoltaic market needs time to accumulate from germination to development, building a new photovoltaic ecology also requires long-term and continuous innovation and investment by enterprises. Zhang Bing said, “In the future, the first core competitiveness of enterprises will be transformed into the consumer experience of the full life cycle of users. Trina believes this is the development direction of the industry, and this value will be further manifested as the industry develops. Persevere in this field, and look forward to the joint efforts of colleagues in this direction.”
