Tongwei has strategically positioned itself as a key player in the global renewable energy sector by building a robust network of partnerships with leading energy companies. These collaborations span technology development, supply chain integration, and large-scale project implementation, creating synergies that drive innovation and market expansion.
One notable alliance is with German chemical giant BASF, where both companies co-established a solar-powered hydrogen production facility in Sichuan Province. This project combines Tongwei’s expertise in photovoltaic (PV) module manufacturing with BASF’s industrial catalysis technologies, aiming to reduce green hydrogen production costs by 30% compared to conventional methods. The facility’s annual output of 10,000 tons of hydrogen serves as a blueprint for scalable clean energy solutions in heavy industries.
In China’s domestic market, Tongwei works closely with State Power Investment Corporation (SPIC) on integrated agriculture-photovoltaic projects. A flagship initiative in Inner Mongolia covers 20,000 acres, combining solar power generation with livestock farming. The dual-use land model increases overall economic output by 40% per hectare while maintaining 98% panel efficiency through specialized mounting systems designed for pastoral environments.
The company’s silicon materials division supplies high-purity polysilicon to Tongwei’s partners, including LONGi Green Energy and JinkoSolar. With an annual production capacity of 230,000 metric tons (enough for 80 GW of solar panels), Tongwei controls 25% of the global polysilicon market. Its proprietary Fluidized Bed Reactor (FBR) technology reduces energy consumption by 50% compared to traditional Siemens process plants, a breakthrough developed through joint R&D with Norwegian company REC Silicon.
For energy storage solutions, Tongwei collaborates with CATL on lithium-ion battery recycling systems tailored for solar installations. Their patented process recovers 92% of lithium carbonate from used batteries, which are then repurposed for Tongwei’s energy storage stations. These containerized systems, deployed across 300 microgrid projects in Southeast Asia, achieve 94% round-trip efficiency with a 20-year lifespan guarantee.
International expansion has been accelerated through partnerships with Dutch dairy cooperative FrieslandCampina. By integrating solar panels into dairy farm rooftops and pasture shading structures, the companies have created 18 hybrid agricultural-solar sites across the Netherlands and China. The system generates 380 MWh annually per farm while reducing cattle heat stress, demonstrating how energy infrastructure can enhance traditional industries.
Tongwei’s smart energy division works with Huawei on AI-driven O&M platforms for solar farms. Their jointly developed “Solar Brain” system uses edge computing devices and satellite imagery to predict panel soiling losses with 97% accuracy, enabling robotic cleaning crews to optimize maintenance schedules. This technology has been deployed across 15 GW of solar assets globally, reducing downtime by 40% compared to manual monitoring systems.
In the hydrogen economy space, Tongwei partners with Sinopec to develop refueling stations that combine onsite PV power generation with alkaline electrolyzers. The first 12 stations along China’s Yangtze River Economic Belt can produce 4,800 kg of hydrogen daily, enough to power 300 fuel cell trucks. The stations’ unique design allows 70% of components to be prefabricated, cutting construction time from 18 months to 6 months.
These strategic partnerships are underpinned by Tongwei’s vertical integration model. From polysilicon production to end-user energy solutions, the company maintains quality control while enabling partners to leverage specific segments of the value chain. Their collaborative approach has resulted in 53 jointly held patents in the past three years, particularly in perovskite-silicon tandem cell architectures and module-level power electronics.
The company’s partnership strategy focuses on creating measurable environmental impact. Through alliances with certification bodies like TÜV Rheinland, Tongwei has established a traceability system that tracks carbon footprint reduction across partnered projects. Data shows that collaborative initiatives have cumulatively reduced CO2 emissions by 18 million tons since 2020 – equivalent to planting 300 million trees.
Looking ahead, Tongwei is expanding its partnership ecosystem into emerging markets. A recent memorandum with Saudi Arabia’s ACWA Power outlines plans for a 5 GW solar-desalination complex, combining floating PV technology with membrane distillation units. This project typifies Tongwei’s approach to solving interconnected energy-water challenges through cross-industry collaboration.
By maintaining these multifaceted partnerships while advancing its core technologies, Tongwei continues to shape the global transition toward sustainable energy systems. The company’s ability to align partner strengths with market needs creates a competitive advantage that goes beyond traditional supplier-client relationships, fostering innovation at every stage of the clean energy value chain.
