Li Zhenguo Net Worth

Li Zhenguo has an estimated net worth of $2.4 billion, according to Forbes Real-Time Billionaires, Li Zhenguo profile (figures as of October 20, 2026). That is up from $2.2 billion in 2020.

Li Zhenguo is a Chinese businessman and the cofounder, president and chief executive of Longi Green Energy Technology, one of China's largest manufacturers of solar wafers and modules. He was born on 5 January 1968. He leads the company he helped start.

After graduating from Lanzhou University, he worked at the state-owned Huashan Semiconductor Materials Factory. He went on to run the Shanxi Wenxi Xinda Electronic Parts Factory, then directed the crystal base of a Xi'an University of Technology factory and served as general manager of Xi'an Lijing Electronic Technology. He struck out on his own during the 1990s.

Forbes describes him as self-made. His career has been built on silicon, first in semiconductors and then in solar power. His experience running factories gave him the technical and management background to start his own company.

How Li Zhenguo made his money

Li cofounded Longi in 2000 with classmates from Lanzhou University and his wife, Li Yanxi. He named the company after Jiang Longji, the former headmaster of the university. At first Longi supplied reprocessed silicon materials, and only later did the founders decide to focus on solar. As of 2022, it was the world's biggest maker of monocrystalline silicon for solar.

Longi is listed in Shanghai and has over 60,000 employees, with production bases in China, Malaysia and Vietnam. In 2021 it announced plans for overseas plants, including in India, Saudi Arabia and the US. In 2023 it announced a plan to raise $2.8 billion through an offering in Switzerland. Its factories serve solar customers around the world.

How Forbes has valued Li Zhenguo

Forbes valued Li at $2.2 billion in 2020. His figure jumped to $10.5 billion in 2021 and peaked at $12.9 billion in 2022. That made him one of the richest people in China's solar industry at the peak.

It then fell sharply, to $8.5 billion in 2023, $4.3 billion in 2024 and $3.4 billion in 2025, before rising to $3.8 billion on the 2026 World's Billionaires List. As of October 20, 2026, the Forbes real-time billionaires tracker showed $2.4 billion. Few fortunes on the list have risen and fallen as quickly, since his wealth moves with Longi's share price. His October 2026 figure was well under a fifth of his 2022 peak.
