In 2022, the domestic market share of Tongwei Shares exceeded 30%. As a specialized solar cell manufacturer, Tongwei has ranked first in the world in terms of battery shipments for six consecutive years since 2017. The efficiency
of Tongwei modules has broken the record
. In the photovoltaic industry with the main theme of reducing costs and increasing efficiency, the way to increase efficiency is undoubtedly reflected in the power of batteries and modules. At present, the power of HJT components in the industry is basically more than 700 W. 745.62
W is the latest record of Tongwei HJT components. In 2023, Tongwei continued to achieve breakthroughs in the power of heterojunction products. From January to July 2023, Tongwei repeatedly announced the latest record results of the power and efficiency of heterojunction modules. Today, Tongwei's component efficiency has increased from 720.71W at the beginning of the year to 745.62 W at present. The good performance of Tongwei shares also shows that the power potential of Tongwei HJT component products is infinite. In
2023, the photovoltaic industry ushered in the key node of N-type technology replacing P-type technology. Therefore, the production capacity of N-type batteries and components is expanding, and the product efficiency has also achieved breakthroughs. The N-type technology route mainly includes TOPCon, IBC and HJT battery technologies. In the choice of N-type technology route, Tongwei has previously announced that it will choose both TOPCon and HJT technology routes.
You know, among the leading photovoltaic enterprises in China, Jingke Energy focuses on the development of TOPCon technology, Aixu shares choose to devote themselves to ABC technology, while Huasheng New Energy focuses on HJT technology. Tongwei's decision became the first company in the industry to announce simultaneous efforts on two major technological routes. In addition, Tongwei has a layout in THL, xBC, perovskite stack and other technical fields, from which we can see the ambition of Tongwei. Tongwei chooses two technical routes in parallel, on the one hand, it can grasp the rapid development period of TOPCon, on the other hand, it can make breakthroughs and upgrades in HJT technology, and make profits without delay. At present, Tongwei's achievements also show its strong technological research and development and manufacturing capabilities.
In terms of N type, Tongwei is also developing continuously. In terms of TOPCon technology, Tongwei has built and put into operation 25 GW battery capacity in Meishan, Sichuan, with the mass production battery efficiency reaching 26.0% and the module power exceeding 585 W. In terms of HJT technology, Tongwei has continuously invested in R & D resources to promote HJT technology to achieve cost reduction and efficiency enhancement. It is reported that in order to better promote the development of HJT technology, Tongwei has established HJT pilot and mass production lines in Hefei, Anhui and Jintang, Sichuan, respectively, to verify the advanced nature of HJT technology. That is to say, Tongwei is committed to pushing HJT technology into the process of large-scale application. In addition, Tongwei also carries out R & D layout on multiple interconnection technology routes, and continues to carry out research on high-reliability HJT packaging technology solutions to promote the development of HJT technology.
Since Tongwei laid out HJT technology, many achievements have been made. In 2021, Tongwei built the first GW-grade HJT production line in China, and completed the development of the industry's first double-sided microcrystal in January 2023. Tongwei Co., Ltd. is the first company to adopt copper interconnection (THL) technology, which is also an important route for the development of heterojunction modules in the future. According to the relevant data, THC module has great advantages such as higher double-sided rate, lowest temperature coefficient of -0.26%/℃, 1% attenuation in the first year, no more than 0.375% attenuation per year, and no less than 88% of the initial power after 30 years.
In short, Tongwei shares are exploring the way to reduce costs and increase efficiency, and to open up the development prospects of the photovoltaic industry.
Who would have thought that Tongwei shares, which have made breakthroughs in the efficiency of HJT components, would not officially enter the component business until 2022. According to the official information, Tongwei has formed a complete photovoltaic new energy industry chain with independent intellectual property rights from upstream high-purity silicon production, midstream high-efficiency solar cells and components production to terminal photovoltaic power plant construction and operation, relying on the dual leading advantages of "global high-purity silicon leading enterprises" and "global solar cell leading enterprises".
Tongwei's development in the component sector is also booming. At present, Tongwei has established a very perfect level of large-scale component business system. According to InfoLink statistics, in the first half of 2023, Tongwei ranked sixth in the global component shipment list, and its performance was quite excellent.
According to the data of the third quarterly report, in the first three quarters of 2023, Tongwei's component shipments were about 18 GW, of which the first quarter was about 3 GW, the second quarter was about 6 GW, and the third quarter was about 9 GW, showing an upward trend quarter by quarter. At present, Tongwei shares have laid out component production bases in many places, including Hefei, Yancheng, Nantong, Jintang and other places. In 2023, Tongwei's module production capacity is expected to reach 80GW.
In terms of component orders, Tongwei shares also performed very well. In September 2023, Tongwei announced that it would join hands with Energy 3000 to build a ground photovoltaic power generation project in Austria. As early as February 2023, Tongwei signed a three-year cooperation framework agreement with Energy 3000, which is the first heterojunction (HJT) component project under the framework agreement, and also the first overseas heterojunction (HJT) component promotion project of Tongwei.
In addition, according to relevant information, on November 13, Tongwei Component New Product Release and Global Partner Conference will be held in Chengdu, and Tongwei New Product Large Rectangular Sheet Products will also make its first public appearance.
In a word, as a leading solar photovoltaic enterprise, Tongwei shares continuously promote the development and innovation of photovoltaic technology. In the future, we hope to continue to promote the healthy development of the photovoltaic industry through Tongwei's continuous exploration of various technical routes. At the same time, it can also contribute to the global energy transformation.
