Longi Green Energy Technology Co., Ltd. (hereafter "LONGi") stands at the forefront of the global photovoltaic (PV) industry as a trailblazer in sustainable energy solutions. With a mission to "create a better and greener home for humanity," LONGi has transformed from a domestic solar technology enterprise into a global leader, driving innovation in high-efficiency solar cells and modules. This article delves into LONGi's evolution, current status, cutting-edge product offerings, and its expansive global footprint.
Development History
LONGi was founded in 2000 by Mr. Li Zhenguo in Xi'an, China, initially focusing on the production of monocrystalline silicon materials for semiconductors. Recognizing the immense potential of solar energy in addressing climate change, the company shifted its focus to photovoltaics in 2006. This strategic pivot marked the beginning of LONGi's journey to revolutionize the PV industry.
By 2012, LONGi had completed its initial public offering (IPO) on the Shanghai Stock Exchange, fueling rapid expansion into advanced solar technologies. The company’s early investments in research and development (R&D) yielded breakthroughs in monocrystalline silicon wafers, achieving higher efficiency and lower costs compared to traditional polycrystalline alternatives.
Over the next decade, LONGi solidified its dominance in the global market through relentless innovation. Key milestones include:
- 2014: Establishment of its own module manufacturing division to achieve vertical integration.
- 2017: Launch of the PERC (Passivated Emitter and Rear Cell) solar cell technology, significantly boosting energy conversion efficiency.
- 2020: Introduction of the HI-MO 4 series, featuring bifacial modules for dual-sided energy generation.
- 2023: Unveiling the HI-MO 9, a groundbreaking BC (Back Contact) solar module designed to maximize power output while minimizing balance-of-system costs.
Today, LONGi is recognized as the world’s largest producer of monocrystalline silicon wafers and a top-tier provider of integrated PV solutions.
