Key Takeaways

  • Tongwei Group of China says it has successfully operationalized the world’s first unmanned monocrystalline solar cell production line
  • Tonwei calls this production concept 4.0
  • The line is located in Shuangliu district of Chengdu
  • The line has a nameplate capacity of 2 GW with a potential to manufacture around 1.35 million high performance solar cells per day
  • Now, the group has a total monocrystalline solar cell capacity of 3.4 GW and 2 GW of multicrystalline solar cell capacity

China’s Tongwei Group has put in operation what is calls the world’s first technically unmanned monocrystalline solar cell production line. The S2 plant, referred to as 4.0, is located in Chengdu region’s Shuangliu district.

A news portal GoChengdu.cn reported that the project consists of two phases. The first phase entered commercial operations with 1,000 MW capacity in June 2016. In the second phase, the group has added a capacity of 2 GW. The entire plant covers floor area of 28,000 m2. It can manufacture around 1.35 million high performance cells on a daily basis.

With this 2 GW of nameplate capacity coming online, the company now boasts of a total monocrystalline solar cell capacity of 3.4 GW. This is in addition to its 2 GW of multicrystalline solar cell capacity, which means Tongwei now operates 5.4 GW of cell production capacity.

Earlier this year, Tongwei joined hands with fellow Chinese solar cell/module producers Longi and Trina Solar to build a 5 GW of monocrystalline silicon ingot crystal growth facility in China (see Longi, Trina & Tongwei To Build Ingot Factory). Tongwei will be participating in this project through its subsidiary Yongxiang Co., Ltd. Tongwei Group is also cooperating with the Longi Group on building a 50,000 ton silicon factory in Sichuan province.
