The company also announced that it increase monocrystalline wafer production by a further 10GW as part of a Phase 2 expansion at facilities in Chuxiong, Yunnan, China. Capital expenditure for Phase 2 was put at around RMB 1.486 billion (US$222.1 million). 

The company had also announced separately that it was expanding monocrystalline solar cell capacity by 1GW at a new facility at the Shama Jaya Free Industrial Park, Kuching City, Sarawak, Malaysia at a cost of approximately RMB 840 million (US$125.5 million), which brings total investments planned of around US$898.5 million, so far in 2019. 

The investment in the ingot facility in Baoshan is expected to be carried out through July, 2020, while the Lijiang project will take through May, 2020. The 10GW mono wafer project is expected to be completed in March, 2020.
 
LONGi said that it was continuing to expand capacity to meet future projected demand for high-efficiency mono wafers, while targeting production in Yunnan Province, due to the availability of hydro-electric power. 

The company had previously announced that it had near-term plans to expand wafer production to 45GW by the end of 2020. The latest expansion announcements would take nameplate capacity to 38GW in 2019.

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.
