Longji Longxing

Longi Green Energy Technology Co., Ltd. has its group headquarters and wafer division headquarters both located in Xi'an, Shaanxi. It fully utilizes regional resource advantages, relying on a healthy financial situation and a strong R&D team, to lay out and optimize the industry with Xi'an as the center, including locations such as Yinchuan and Zhongning in Ningxia, Wuxi in Jiangsu, Chuxiong, Baoshan, Lijiang, and Qujing in Yunnan. Since 2015, it has developed into a leading global manufacturer of monocrystalline silicon products and established a new overseas production base in Malaysia in 2016. By the end of 2019, the company's monocrystalline silicon wafer capacity reached 42GW, exceeding the expected capacity planning goals. By the end of 2020, the annual capacity of monocrystalline silicon wafers reached over 75GW, and will continue to expand at a high growth rate, providing favorable resource guarantees for Longi's global capacity growth and sufficient supply of monocrystalline products. The wafer division of Longi, with its forward-looking vision, is dedicated to providing the world with more reliable and efficient monocrystalline products. In collaboration with dozens of renowned international photovoltaic research laboratories, as well as multiple domestic research institutions and universities, it has invested substantial funds to build a powerful monocrystalline R&D platform, gathering the wisdom of 548 technical R&D talents globally, and establishing 568 core technology patents, cementing Longi's technological leadership in the monocrystalline product sector. It was also the first among other monocrystalline manufacturers to propose the concept of "unified monocrystalline silicon wafer size," significantly promoting the standardization of the industry, the development of thinner monocrystalline silicon wafers, and increasing the market share of N-type high-efficiency monocrystalline silicon products. We possess world-leading diamond wire cutting technology, achieving 100% diamond wire cutting for monocrystalline silicon wafers in the industry in 2015. We consistently strengthen the establishment of a lean quality management system to ensure that every monocrystalline silicon wafer meets excellent quality standards, satisfying customer requirements. With a scientific and rigorous attitude, the people of Longi spare no effort in improving and enhancing the production process of monocrystalline silicon ingots, improving the RCZ crystal pulling process, reducing oxygen content, and increasing the lifetime value of the ingots. They precisely control every manufacturing step, within their unique intelligent manufacturing workshops, where polycrystalline silicon raw materials are loaded into Longi's self-developed and improved monocrystalline furnaces, undergoing a stringent crystal pulling process to produce monocrystalline silicon ingots with perfect lattices.
