China-based integrated and merchant PV manufacturer Tongwei Group recently opened its completed high-efficiency solar cell plant (S2), which includes the world’s first technically unmanned monocrystalline solar cell production line under the intelligent manufacturing term, 4.0. 

The S2 plant in Chengdu, China has an initial nameplate capacity of 2GW, which brings Tongwei’s monocrystalline cell capacity to around 3.4GW. The company also has around 2GW of multicrystalline solar cell capacity. The 4.0 cell line is completely unmanned to test intelligent fully automated manufacturing tools and software systems.

Tongwei chose to officially launch the new facility in tandem with a massive ceremony celebrating the company’s 35 years of business operations. 

The company has also recently completed a 5,000MT polysilicon plant expansion, bringing nameplate production capacity to 20,000MT. However, the company is also undertaking the construction of a new 50,000MT polysilicon plant. 

Recently, GCL-SI (GCL System Integrated Technology) established a module assembly workshop that was completely unmanned to test intelligent fully automated manufacturing tools and software systems under its own manufacturing 4.0 initiative.

PV Tech has been running an annual PV CellTech Conference since 2016. PV CellTech USA, on 7-8 October 2025 is our third PV CellTech conference dedicated to the U.S. manufacturing sector. The events in 2023 and 2024 were a sell out success and 2025 will once again gather the key stakeholders from PV manufacturing, equipment/materials, policy-making and strategy, capital equipment investment and all interested downstream channels and third-party entities. The goal is simple: to map out PV manufacturing in the U.S. out to 2030 and beyond.
