Tongwei Group

What Tongwei Group does

Tongwei Group is a privately-held Chinese multinational founded in 1982 and headquartered in Chengdu, Sichuan. It operates two principal business pillars: Green Energy, built around fully vertically-integrated photovoltaic manufacturing from high-purity crystalline silicon (subsidiary Yongxiang Co., Ltd., the world's largest polysilicon producer with over 25% global market share) through solar cells (Tongwei Solar / TW Solar, 95GW capacity) and modules (75GW capacity) to PV power station development via the proprietary 'Integration of PV and Fishery' model (4.07GW); and Green Agriculture, where it is the world's largest aquatic feed manufacturer with 10 million tons of annual production capacity. The Group's PV technology stack includes the proprietary TNC 3.0 TOPCon platform with 360° passivation, THC-G12 heterojunction copper-interconnect modules, the 908 zero-busbar technology, and the Yongxiang Method for 11-nines purity silicon, supported by over 1,000 IP rights in polysilicon and more than 2,000 patent applications at Tongwei Solar. The Group operates nearly 400 branches and subsidiaries with 60,000+ employees, exporting modules to more than 80 countries, and is the only Fortune Global 500 enterprise in the global PV industry, with a 2026 brand value of 275.639 billion yuan. Revenue is generated primarily through B2B enterprise field sales of PV hardware, polysilicon supply to other manufacturers, project-based PV power station development, and aquaculture feed sales, with go-to-market executed through direct export, regional system integrators (e.g., ACO in Egypt), and channel partners (COENERGIA, Energy3000, Memodo in Europe) supported by major industry exhibitions such as Intersolar Europe and SNEC.

Core offering

Tongwei Group is a multinational industrial enterprise operating two core businesses: a vertically integrated Green Energy business spanning the full photovoltaic value chain (polysilicon, solar cells, modules, and solar power stations), and a Green Agriculture business focused on aquatic animal feed and related nutritional products. The company is the world's largest producer of crystalline silicon solar cells and one of the leading global aquaculture feed suppliers, with additional expansion into adjacent industries such as pet food.

Product overview

Tongwei Group is a large multinational company with two core business segments: Green Energy (photovoltaic products) and Green Agriculture (aquaculture feed). The photovoltaic division offers a comprehensive product portfolio spanning the entire PV industry chain from high-purity crystalline silicon (via subsidiary Yongxiang Co., Ltd.) to solar cells and modules. Key PV module products include the TNC 3.0 and TNC 2.0 series based on TOPCon technology, and the THC-G12 heterojunction copper-interconnect series. The company also operates PV power stations using its proprietary 'Integration of PV and Fishery' model. In agriculture, Tongwei is the world's largest aquatic feed manufacturer with 10 million tons annual production capacity. Additional diversification includes pet food and other related industries.

Direct peers

• Canadian Solar: Canadian Solar is a major international PV module manufacturer with a strong global project development business (CSI Solar). Comparable to Tongwei's module and project development businesses, particularly in markets where Tongwei is still building presence.
• LONGi Green Energy Technology: LONGi is one of the world's largest vertically integrated solar manufacturers, producing wafers, cells, and modules. It is the most directly comparable peer to Tongwei in the integrated PV space and is even a Tongwei strategic partner for silicon cooperation.
• GCL Technology Holdings: GCL Technology is a major polysilicon producer and one of Tongwei's closest direct competitors in upstream polysilicon. Comparable on the silicon production side, though GCL has a different downstream footprint than Tongwei's integrated cell/module operations.
• JinkoSolar: JinkoSolar is a top-three global PV module manufacturer with vertically integrated cell and module production. Directly comparable to Tongwei Solar's TNC and THC module lines and competes head-to-head in international utility-scale and distributed markets.
• Trina Solar: Trina Solar is one of the largest vertically integrated PV module manufacturers globally. Comparable to Tongwei Solar's module-focused business, with overlapping product roadmaps in TOPCon and HJT technologies and similar global distribution.
• Daqo New Energy: Daqo is a high-purity polysilicon producer and direct competitor to Yongxiang (Tongwei's polysilicon subsidiary). Comparable on the upstream silicon side with overlapping customer bases among wafer, cell, and module manufacturers.
• BioMar Group: BioMar is one of the world's largest dedicated aquaculture feed producers, focused exclusively on fish and shrimp feed. Directly comparable to Tongwei's aquaculture feed business in product category, though at smaller scale and without Tongwei's PV exposure.
• Charoen Pokphand Foods: CPF is a Thailand-based agro-industrial conglomerate and one of the world's largest aquaculture feed and food producers. Comparable to Tongwei's aquaculture feed business as a leading global player in aquatic feed, with similarly integrated operations across animal protein.
• JA Solar Technology: JA Solar manufactures silicon wafers, cells, and modules and ranks among the top global PV suppliers. Comparable to Tongwei Solar on integrated cell/module production and competes in the same utility-scale and C&I channels worldwide.

Broad incumbents

• First Solar: First Solar is the largest Western PV module manufacturer, using thin-film CdTe technology rather than crystalline silicon. Operates in the broader PV space and competes for utility-scale projects, but its technology platform is fundamentally different from Tongwei's crystalline silicon focus.
