Tongwei PV Industry Integration

Tongwei entered the market of photovoltaics (PV) in 2006. After more than 10 years of rapid development, Tongwei has become an integrated PV enterprise with the production of high-purity polysilicon and wafers in upstream, high-efficiency solar cell production and high-efficiency PV module production in midstream, as well as experience in PV power plant construction and operation. It has formed a complete PV new energy industry chain with independent intellectual property rights and leading scale, technology, cost, and quality advantages, building up the vertically integrated layout of the whole PV industry chain. It is continu­ously strengthening key areas, focusing on high-purity silicon, high-efficiency cells and module products in manufacturing, and innovatively developing an “Fishery & PV Integration” model in application. It has become a global leader and main driving force in the photovoltaic new energy industry.Tongwei Solar (Modules), a wholly-owned subsidiary of Tongwei Co., Ltd, is devoted to the in-depth R&D, intelligent manufacturing, and application promotion of high-efficiency photovoltaic modules. Leveraging Tongwei’s vertically integrated industry chain, the company has developed a technology R&D system with complete intellectual property rights, a production system that leads in intelligence and digitalization, and a globally oriented market and business service system. With four major production bases in Hefei, Jintang, Yancheng, and Nantong (under construction), the company has a production capacity of 63GW and employs over 11,000 people. In order to meet the urgent market demand for high-quality photovoltaic products, the company expanded its business scope comprehensively in the second half of 2022.
