LONGi monocrystalline silicon wafers are committed to the development of green energy and promote the progress of the PV industry. At present, it has the world's largest monocrystalline silicon wafer production capacity, and ranks the first of monocrystalline silicon wafer shipments in the world. And it has established a comprehensive sales channel and rapid service response capability on a global scale, and is committed to providing high quality monocrystalline silicon products and ancillary services to global PV companies.

LONGi monocrystalline silicon wafer production bases are located in Yinchuan, Zhongning, Wuxi, Chuxiong, Baoshan, Lijiang and Malaysia. By the end of 2020, the capacity of monocrystalline wafer has reached 85GW.
  • High Quality
    The quality management system is built to ensure every piece of monocrystalline wafer can have good quality and meet the demand of customers.
  • R&D Efficiency
    The  R&D results have been closely integrated to production equipment hardware. With the leading technologies on large loading, high pulling speed and several times of crystal pulling, it can greatly improve the production efficiency of crystal pulling.
  • Leading Technology
    LONGi has continuously improved its RCZ crystal pulling process via technical improvement. The oxygen content has been reduced during manufacturing of Monocrystalline Silicon Ingot with aim to produce the Monocrystalline Silicon Ingot of perfect lattice.
  • Lower Cost
    LONGi silicon has world leading technology such as Diamond Wire Slicing Technology and thickness production technology. In 2015, it became the first PV manufacture who implement Diamond Wire Slicing Technology , promoting the industrial progress and reducing the industrial production cost.
