Longi had previously announced plans for the 5GW monocrystalline silicon ingot plant in June, 2016 and had initially planned to fund the facility in-house. However, Longi noted that in a JV arrangement it was reducing financial and project risks. 

The company has a range of other dedicated in-house capacity expansions for monocrystalline wafer, cell and modules. 

Silicon Module Super League (SMSL) member Trina Solar is expected to contribute an initial RMB 200 million (US$28.8 million) to the project and Sichuan Yongxiang around RMB 120 million (US$17.3 million). 

Longi still expects to contribute an initial RMB 480 million (US$69 million) to the project, which is expected to incur capital costs of around RMB 800 million (US$115 million). The plant is expected to take more than a year to build and start ramping sometime in 2018. 

According to Finlay Colville, Head of Market Research at Solar Media Ltd, in a new blog on the news, the JV in not unexpected as it forms part of one of the most pro-active technology drives seen for many years within the industry.

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.
