Company history
LONGi traces its origins to Xi’an Xinmeng Electronic Technology Co., Ltd., established on 14 February 2000; the company identifies Li Zhenguo as its founder [25][26]. It listed on the Shanghai Stock Exchange in April 2012, the year it also reached 1 GW of wafer capacity [27][28]. In 2014, LONGi acquired Zhejiang LERRI Solar, expanding into solar-cell and module research, manufacturing and sales [28][29].
In 2017, LONGi reported a Fraunhofer ISE-certified monocrystalline PERC cell efficiency of 22.71% [30]. It launched the Hi-MO 5 module in 2020, with volume production beginning that September [31][32]. In October 2024, it introduced the Hi-MO X10 module, based on its HPBC 2.0 cell technology [33]. Its 2025 annual report later described progress in wafer manufacturing technology and cell and module efficiency records [34][35]. [34][35][25][26][27][28][29][30][31][32][33]
