Trina Solar Commissions 15.5 GW Solar Manufacturing Complex In Vietnam

Trina Solar's Module Shipments Total 140 GW, 210mm Module Shipments Exceed 65 GW by Q1 '23

Keeping up with its international manufacturing expansion, Chinese solar major Trina Solar has commenced the production of 210mm monocrystalline silicon wafers in Vietnam. The first wafers rolled off the production line at the factory in Thai Nguyen city, 80 kilometers north of Hanoi, on Aug. 23. The factory will be able to produce 6.5 GW of wafers per year. With this new capability, Trina Solar will have greater flexibility to deliver its products worldwide. Trina Solar has been one of the earliest, and biggest backers of the 210mm size for wafers and cells, hoping to make it a global standard vis a vis the 182 mm size from rivals Longi solar and others.

The green light for production was given on July 31 and the first 12-inch monocrystalline silicon rod rolled off the assembly line on August 4, foreshadowing the production of the first wafers.

In addition to the 6.5 GW wafer production capacity of the new factory, it has a cell capacity of 4 GW and a module capacity of 5 GW. The silicon wafer factory includes monocrystalline extraction, square processing of silicon rods, cutting and processing of silicon. The wafers produced are mainly used in the production of cells and modules at Trina Solar’s facilities in Vietnam and Thailand, including supplying Trina Solar to the US market.

The Vertex modules that Trina produces outside of China help meet the growing global demand for PV modules with high power, high efficiency, high reliability, high energy performance and low LCOE. The silicon rod and wafer production of the Vietnam factory will ensure a steady supply of materials for other module production sites the company has overseas.

With the production of 210mm n-type i-TOPCon cells in Qinghai Province starting in early August, Trina Solar integrated the entire Qinghai factory process and is accelerating the formation of an n-type integrated industrial design.

Chinese solar majors have increasingly ventured out in the past few years to make outside China, as fears of sanctions and the need for better logistics for distant markets drives the move. Importantly, these foreign locations are going beyond just assembly units to full fledged manufacturing points now, as scrutiny becomes tighter over source of imports in key markets like the US, Europe and India. Over 30 GW of capacity has been created outside China by solar majors from that country till now.
