Solar for Solar

LONGi supports the “Solar for Solar” business model. While creating low-cost clean energy products for the world, the company uses clean energy and green manufacturing practices in its operations whenever possible. Since 2015, LONGi has located its operations in Yunnan, China, and Kuching, Malaysia, to utilize the abundant local hydropower resources to provide clean energy for its facilities. LONGi plans to integrate solar power plants with pumped storage in areas that feature significant elevation differences and abundant sunlight, creating an industrial model for using solar.

In 2018, Li Zhenguo, founder and president of LONGi, visited Cambridge University while attending a PhD program at Tsinghua University. During the visit, Professor Martin Reese, a renowned astrophysicist and former Dean of Trinity College in Cambridge University, depicted a prediction of what the Earth might look in 2050, emphasizing that the ecological damage caused by human activities in the past 100 years was still increasing and might be irreparable. Reese shared his serious concerns about the Earth’s future in his teaching. Stephen Hawking, the world-famous physicist, also predicted that human beings will be forced to leave the earth by 2060 because of energy depletion. Then human survival will be threatened at that time. Many great minds have underestimated the speed at which PV is growing and the contributions it can make to the planet’s ecology and health. LONGi believes that PV can change the ecology of this planet, which is another reason for the development of the “Solar for Solar” model.

1986

LONGi is named after the former president of Lanzhou University. In 1986, when Li Zhenguo and Zhong Baoshen had just enrolled, the formal opening ceremony of Lanzhou University was held before the statue of its president, Jiang Longji. His inspirational life story planted the seeds of a long-cherished dream in their hearts: We will name our company LONGi! LONGi represents a continuum of cultures and education-driven technologies.
