Confidence rating:

Li's wealth is derived from his 19% stake in Longi Green Energy Technology, a solar panel company. The Xi'an, China-based business is the world's biggest producer of solar wafers meeting about one-quarter of the world's demand, according to its website.

Li owns the shares directly and with his wife, according to the company's 2022 third-quarter report. About 4% of his stake is pledged and removed from the net worth calculation. The valuation was updated on Dec. 8, 2022 to reflect a reduction in the pledged share count and this led to an increase in the calculation of about $500 million.

A liability is included based on an analysis of insider transactions, dividends, taxes and market performance.

Feng Li, a spokesman for the company, declined to comment on the net worth calculation.


Family: Married, No children

Li was born in May 1968. He studied physics in central China before graduating from Lanzhou University at the age of 22.

He began his career at a state-owned factory that made mono-crystalline silicon rods, according to an interview Li gave in 2019.

Li founded the predecessor of Longi in Xi'an, China in 2000. By 2007, it had built a silicon ingot facility with a 1000 tonne capacity, according to the company's website.

Longi started trading publicly trading in Shanghai in 2012. Lerri Solar was acquired in 2014.

The company was responsible for about one-quarter of the world's demand for solar modules and wafers in 2020.
