Jinko Solar

JinkoSolar Holding Co., Ltd. is one of the world’s largest and most established solar module manufacturers, headquartered in Shanghai, China. Founded in 2006, the company has grown from a regional Chinese manufacturer into a global photovoltaic giant, supplying solar panels to residential, commercial, and utility-scale projects across multiple continents. Today, Jinko Solar is publicly listed on the New York Stock Exchange, with a secondary listing in China, and operates one of the largest vertically integrated solar manufacturing operations in the world.

From a homeowner’s perspective, Jinko Solar is best understood as a high-volume, industrial-scale manufacturer whose products appear widely across global markets, including the UK and Europe, rather than as a niche or specialist brand.

Early growth and global expansion

JinkoSolar was established in December 2006 in Shangrao, Jiangxi province, during a period of rapid expansion in China’s solar manufacturing sector. The company grew quickly and was listed on the New York Stock Exchange in 2010, giving it access to international capital markets and accelerating its global expansion.

As demand for solar panels increased worldwide, Jinko invested heavily in manufacturing capacity, supply chains, and international distribution. By the mid-2010s, the company had expanded production beyond China, including the establishment of manufacturing operations in Malaysia in 2015. This marked the beginning of a more international manufacturing footprint, alongside its core Chinese production base.

Jinko’s panels became increasingly common in large-scale solar projects as well as rooftop installations, and the company built a reputation as a high-volume supplier capable of delivering at scale.

Manufacturing model and technology development

A defining feature of Jinko Solar’s business model is its vertical integration. The company produces ingots, wafers, solar cells, and finished modules in-house, rather than relying heavily on external suppliers. This structure gives it tighter control over costs, quality, and production capacity, and is one of the reasons it has been able to scale so rapidly compared to many competitors.

Jinko has also invested heavily in cell technology development. In 2019, the company began mass production of n-type TOPCon cells, marking a shift toward higher-efficiency architectures. This technology focus has shaped many of its more recent product lines, particularly in the residential and commercial markets.

The company’s manufacturing network continued to expand internationally, including the opening of a US factory in 2019 and the establishment of production facilities in Vietnam in 2022. These moves reflected both commercial strategy and the need to respond to shifting trade rules and supply chain pressures.

Market position and large-scale projects

Jinko Solar is a member of the so-called “Silicon Module Super League,” a group of the world’s largest solar manufacturers that includes Canadian Solar, Hanwha Q CELLS, JA Solar, and Trina Solar. This group dominates global module production and supply.

Beyond rooftop solar, Jinko has also played a role in some of the world’s largest utility-scale solar projects. Notably, it provided equipment and took an ownership stake in the Al Dhafra Solar Project in the United Arab Emirates, one of the largest solar installations globally, which was announced in 2020 and opened in 2023. This highlights the company’s dual presence in both residential-scale and industrial-scale solar markets.

Regulatory scrutiny and supply chain challenges

Like many large Chinese solar manufacturers, Jinko Solar has faced regulatory and geopolitical challenges, particularly in the United States. In 2021, US authorities began blocking imports of some Jinko products over concerns related to supply chain transparency and forced labour regulations. Subsequent investigations and enforcement actions placed increased scrutiny on the company’s sourcing and manufacturing practices.

By 2023 and 2024, regulatory pressure intensified across the wider solar industry, but Jinko emerged as one of the larger manufacturers able to adapt to stricter compliance requirements due to its scale, resources, and supply chain control. This strengthened its competitive position relative to smaller manufacturers.

At the same time, the company pursued further international expansion and capital market access, including plans for a European stock exchange listing announced in late 2024.

Jinko Solar today

Today, Jinko Solar is one of the most prolific solar panel manufacturers in the world by shipment volume. It operates on an industrial scale, with production measured in tens of gigawatts annually, and supplies panels to a wide range of markets, from residential rooftops to large commercial and utility-scale installations.
