Leading 4 Manufacturers of Polysilicon in China; Tongwei Leads the Race

  • All leading 4 suppliers are now located in China; they generated greater than 100,000 MT each in 2022. all leading 4 producers are currently situated in China; they produced greater than 100,000 MT each in 2022.
  • The six biggest Chinese manufacturers alone have additional capacities of about 1.5 million MT in the pipe for 2023 as well as 2024.

According to a Bernreuter Study, all top 4 producers of solar quality polysilicon are now situated in China; they generated greater than 100,000 MT each in 2022.

Chinese polysilicon supplier Tongwei claims it has prolonged its position as the globe market leader in the polysilicon sector. In 2022, the firm created 1.6 times as much polysilicon for solar cells as the 2nd largest manufacturer, GCL Technology, and twice as high as the third greatest, Daqo New Energy, reports Bernreuter Study.

" Exactly how swiftly Tongwei increases its process efficiency and also upgrades existing devices is impressive," remarks Johannes Bernreuter, Head of Bernreuter Research Study. Because an output of virtually 160,000 statistics tons (MT) in the second fifty percent of 2022 alone, the expert estimates that Tongwei got to an effective manufacturing capacity of approx. 345,000 MT by the end of 2022, far above the 260,000 MT formally specified by the firm.

While the top 3 placements in the ranking have stayed unmodified contrasted to the previous year, Xinte Energy has relegated Germany-based Wacker Chemie from the 4th to the 5th location.

An additional China-based producer was additionally amongst the winners last year: Thanks to a smooth ramp-up from a capacity of 22,000 MT to 92,000 MT, Asia Silicon climbed up from the eighth to the 6th ranking. Like Wacker, the company gained from the weak efficiency of East Hope, which had to close down part of its factory in the northwestern Chinese region of Xinjiang for numerous months after a fire burst out in June. Consequently, East Hope slipped from the 6th to the seventh place.

China's Claim in Solar-Grade Polysilicon

China accomplished a share of 89% in the global output of solar-grade polysilicon in 2022, and also expansion proceeds unmitigated. The 6 largest Chinese manufacturers alone have added capacities of approximately 1.5 million MT in the pipeline for 2023 and 2024. In addition to that, greater than a dozen new participants are building or increase new polysilicon plants in China. There are "long-term" prepare for a complete manufacturing capacity of almost 7 million MT, which would amount an annual solar module capacity of approx. 3,500 gigawatts.

" Despite the fact that the possibility for growth of worldwide photovoltaic installments is enormous, it will not absorb such massive polysilicon quantities," says Bernreuter. "Oversupply will be the unpreventable effect. It resembles Chinese investors once more have to learn this by hand offered the fact that they are still revealing new polysilicon projects in 2023."
