A Tongwei announced that until 2024-2026 plans to achieve annual production capabilities of polysilicon high purity solar cells and modules 800 thousand to 1 million tons, 130 to 150 GW and 80 to 100 GW, respectively.
Currently, annual polysilicon production capacity of the company is 450 thousand tons and with the Yunnan Tongwei project's total production of 200 thousand tons, it will increase to 650 thousand tons.
With respect to cells, the manufacturer currently has 95 GW capacity, and regarding the modules count with 75 GW. The company also built 54 photovoltaic plants in various provinces and cities in China, with a cumulative installed capacity of 4,07 GW.
In total, they have more than 200 branches and subsidiaries throughout the country and abroad and employ around 60 thousand people worldwide. Furthermore, as per the Supply Chain Verification conducted by TUV Rheinland, the Module, Wafer, Ingot and Polysilicon sectors achieved AA ratings, respectively, and the Cell sector achieved an A rating.
Tongwei Background: From Polysilicon to Module
Tongwei entered the solar industry in 2006, and after more than a decade of rapid development, it has become a full-chain manufacturer, including upstream high-purity polysilicon production, cell and module production, and construction and operation of downstream photovoltaic plants.
At the beginning of the new energy sector chain, with new projects being signed and built, Tongwei's subsidiary Yongxiang Co., Ltd. has established five main bases in Leshan, Sichuan, Guangyuan, Sichuan, Baotou, Inner Mongolia, Ordos, Baoshan,Yunnan.
According to the company, the main process technology for high-purity polysilicon has been upgraded to the “Eighth Generation Yongxiang Method”, achieving product purity of 99,999999999%, covering electronic grade and solar grade.
As of 2021, Yongxiang Co., Ltd. holds the largest global market share and the largest shipment volume, according to PV InfoLink.
In the green substrate sector, for example, the manufacturer highlighted that it is building industrial silicon projects in an orderly manner, with production expected to begin at the end of 2024.
Too much data
By the end of 2023, Tongwei's cumulative global cell shipments have sured 200 GW, maintaining the highest global cell shipment volume for seven consecutive years, according to PV InfoLink.
Tongwei is also the first company in the industry to sur 100 GW in cell shipments. It currently has four bases in Shuangliu, Meishan, Jintang (the world's first 5G smart park in the photovoltaic sector) and Pengshan, as well as the Tonghe project.
Relying on strong upstream reserves, the company ventured into the module business in 2013 and established a high-efficiency R&D (Research and Development) team in 2016.
After more than a decade of substantial investment and in-depth R&D cultivation, the manufacturer has formed a distinctive module product array that comprehensively covers differentiated market demands and is widely applied in various scenarios such as residential, commercial and industrial rooftops. and centralized generation projects.
Meeting the growing global demand for clean energy, Tongwei said it has accelerated the layout of its module business in the second half of 2022.
Taking advantage of its accumulated technological and market advantages and the synergy of high-purity polysilicon and solar cells, the company has established a competitive large-scale business system. Its customers include China's top state-owned power generation groups and more than 40 countries.
In 2023, they were ranked among the top five in the world in of shipment volume, according to PV InfoLink. Currently, they have production bases in Hefei, Yancheng, Jintang and Nantong. The Shuangliu base is planned and expected to be operational in 2025.
To give you an idea, last year, Tongwei's module sales volume soared 292,08% compared to the previous year, and shipments ranked among the top five in the world.
Commitment to sustainability
Tongwei currently owns four national green supply chain management companies and has obtained 21 carbon footprint certifications. Furthermore, it created a working group dedicated to the traceability of this chain, demonstrating its commitment to environmental protection and the supply of products with concrete actions.
“Tongwei incorporates the principle of sustainable development into its corporate operations and supply chain management, emphasizing the advancement of environmentally friendly procurement practices and the continuous improvement of suppliers' green manufacturing standards. This approach promotes green and low-carbon transformation”, they concluded.
