Solar wafer source matters in today’s U.S. solar market now that the Department of Commerce has placed new tariffs on solar panels imported from Southeast Asia. Solar wafers from China are one of the main components under the microscope.

Trina Solar is one of the top global solar module brands that was not ruled to be circumventing by the DOC. This week, Trina Solar added to its international footprint with the production of 210mm monocrystalline silicon wafers in Vietnam.

The first wafers rolled off the production line of the factory in the city of Thai Nguyen, 80 kilometers north of Hanoi, on Aug 23. The factory will be able to produce 6.5 GW of wafer annually.

In addition to the new factory’s wafer production capacity of 6.5 GW, Trina has cell capacity of 4 GW and module capacity of 5 GW. The silicon wafer factory includes monocrystalline pulling, silicon rod square processing, slicing and silicon processing. The wafers produced are primarily used in cell and module production at Trina Solar’s sites in Vietnam and Thailand, including Trina Solar’s supply to the U.S. market.

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