Three major Chinese PV manufacturers, Longi Silicon Materials, Trina Solar and Tongwei, via its polysilicon subsidiary, Sichuan Yongxiang, are to form a Joint Venture (JV) to own and operate a previously planned 5GW monocrystalline silicon ingot pulling production plant in Lijiang City, Yunnan Province, China, by Longi. 

Longi said in financial filings that it would retain a 60% ownership in the planned production plant, while Trina Solar would hold a 25% interest and Sichuan Yongxiang a 15% stake. 

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.

The global PV market is entering a new era at unprecedented speed. The demand for high-power PV modules has soared, while interest in the future direction of solar technologies has intensified. Tongwei wants to create discussions between EPC companies, investors, and distributors, especially in Europe, which the company sees as a key growth market. Understanding the opinions and needs of clients in terms of shingled or N-type technology, as well as larger module size, is vital to Tongwei’s success in Europe and beyond. In this PV Tech TechTalk webinar, experts from TÜV NORD and Tongwei's CTO will discuss the risk analysis and reliability of the company’s shingled module technology and its applicability to different European markets.
