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.
