The new capacity expansion plans call for a 30GW ingot manufacturing hub to be built in cooperation with the Qujing Municipal People's Government in Qujing City, Yunnan Province, China at a cost of around RMB 3.4 billion (US$483 million).
 
The initial capacity is expected to be 10GW of both monocrystalline silicon ingots and wafers, which are expected start production gradually in 2021. The company is planning expansions of 10GW per annum in a three year phased expansion approach, which would potentially bring future ingot/wafer capacity towards 95GW by the end of 2023.

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.
