Tongwei entered the market of photovoltaics (PV) in 2006. After more than 10 years of rapid development, it has formed a complete PV new energy industry chain with independent intellectual property rights, building up the vertically integrated layout of the whole PV industry chain. Tongwei has become an important participant and significant driving force for the development of China and even the global photovoltaic new energy industry.

TW Solar, as the most critical link in Tongwei's PV new energy industry chain, has deeply engaged in the R&D, manufacturing, and promotion of solar products and has become the world's largest manufacturer of crystalline silicon solar cells and modules with the most advanced technology, production equipment, and the highest level of automation and intelligence in the PV industry. TW Solar has formed a series of fully-flexible, zero-lead, eco-friendly shingled modules and high-efficiency half-cell modules that bring less LCOE and cover the diverse needs of global customers. With over 20,000 employees on its payroll, TW Solar now has six bases in Hefei, Shuangliu, Meishan, Jintang, Yancheng, Nantong, and the Tonghe project, with an annual cell capacity of 70GW and an expected 130-150GW in 2024-2026, of which large-size cell capacity will account for more than 90%. Its annual capacity of high-efficiency modules is estimated to reach 80GW by the end of 2023.
