On June 28, the ceremony marking the start of construction of the Trina Solar (Xining) New Energy Industrial Park project was held 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 210 and N-type technology.
10GW N-type modules on the way, for higher customer value
The factory will include production lines with an annual output of 300,000 tonnes of industrial silicon, 150,000 tonnes 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 will be divided into two phases. In phase I the expected annual output of industrial silicon will be 100,000 tonnes; of high-purity polysilicon 50,000 tonnes, of monosilicon 20GW, of wafer slices 5GW, of cells 5GW, of modules 5GW, and of auxiliaries 7.5GW. Phase I is due to be completed by the end of 2023.
In phase II the expected annual output of industrial silicon will be 200,000 tonnes, of high-purity polysilicon 100,000 tonnes; of monosilicon 15GW, of wafer slices 5GW, of cells 5GW, of modules 5GW, and of auxiliaries 7.5GW. Phase II is due to be completed by the end of 2025.
As the industry rapidly moves towards a new stage of N-type, in line with the company’s strategic development, an industrial chain needs to be established to further improve industrialization of next-generation N-type cell technology, guide the industry towards switching to N-type, and create greater value for customers.
Trina Solar leads N-type technology with solid reservoir of expertise
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 demonstration enterprise 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. In addition, the 8GW N-type production line is running smoothly.
Trina Solar has set world records 23 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 green energy development worldwide.
