2022.07.05

XINING, QINGHAI, CHINA -- On June 28, Trina Solar held a groundbreaking ceremony for its New Energy Industrial Park project in Xining, provincial capital of the central Chinese province of Qinghai. The project will cover almost the entire PV manufacturing chain from polysilicon production to modules based on 210mm and N-type technology.

The factory will include production lines with annual output of 300,000 metric tons of industrial silicon, 150,000 metric tons of high-purity polysilicon, 35GW of monosilicon, 10GW of wafer slices, 10GW of cells, 10GW of modules and 15GW of auxiliaries for modules.

The project development is divided into two phases. Phase I plans include an annual output of 100,000 metric tons of industrial silicon, 50,000 metric tons of high-purity polysilicon, 20GW of monosilicon, 5 GW of wafer slices, 5GW of cells, 5GW of modules, and 7.5GW of auxiliaries. Phase I is due to be completed by the end of 2023.

In Phase II, expected annual output includes 200,000 metric tons of industrial silicon, 100,000 metric tons of high-purity polysilicon, 15GW of monosilicon, 5GW of wafer slices, 5GW of cells, 5GW of modules 5GW, and 7.5GW of auxiliaries. Phase II is due to be completed by the end of 2025.

As the industry rapidly moves toward a new stage of N-type in line with the company’s strategic development, Trina Solar is establishing an industrial chain to further improve industrialization of next-generation N-type cell technology, guide the industry toward switching to the N-type and create greater value for customers.

Trina Solar State Key Laboratory of PV Science and Technology of China has created a series of world records. Four years ago the company was selected as a flagship for China’s Top Runner program with N-type TOPCon technology. In the early stages Trina’s 500MW pilot line has achieved a world record of 25.5% for efficiency, with industry-leading mass production efficiency and an 8GW N-type production line in full operation.

Trina Solar has set world records twenty-three times and the company has built a huge reservoir of expertise and technical assets, including HJT, IBC, and perovskite. Trina Solar will continue to innovate, provide highly reliable and high-value products to global customers, and promote clean energy development worldwide.
