The world’s top four polysilicon producers in 2022 were Chinese companies, led by Tongwei with 345,000 metric tons (MT), followed by GCL Technology, Daqo, Xinte, and Wacker Chemie.
“Considering the output of almost 160,000 tons in the second half from 2022 alone, the analyst estimates that Tongwei achieved effective production capacity of approx. 345,000 MT by the end of 2022, which is clearly over 260,000 MT officially announced by the company,” the consultancy said in a statement.
The second largest polysilicon manufacturer was GCL Technology, followed by Daqo, Xinte and Wacker Chemie.
“Although the positions of the top three in the ranking have remained unchanged Compared to the previous year, Xinte Energy has overtaken Germany Wacker Chemie from fourth to fifth,” Bernreuter Research said. “That’s why all four top manufacturers now located in China; they produced more than 100,000 tonnes each in 2022.”
The sixth largest producer was China’s Silicon Asia, which now has an annual production capacity of 92,000 tonnes, followed by East Hope, which closed part of its production at one of its factories. Xinjiang in the province in June after a fire accident.
“China reached 89 percent of the global production of solar-grade polysilicon in 2022, and expansion will continue steadily. The six largest Chinese manufacturersManufacturers alone have about 1.5 million tons of additional capacity pipeline for 2023 and 2024,” the report states, highlighting the dominance of China’s polysilicon industry. “In addition, there are more than a dozen newcomers construction or commissioning of new polysilicon plants in China.”
According to Polypi analyst Johannes Bernreuter, the main consequence of these expansion plans is overcapacity.
“Although the growth potential of global solar power plants is huge, it doesn’t absorb such huge amounts of polysilicon,” he stated.
