Jinko Solar vs Talesun - solar panel manufacturer comparison

Jinko Solar and Talesun are both Chinese solar module manufacturers, but they occupy very different positions in the global market. Jinko Solar, founded in 2006 and listed on the NYSE, has scaled to a module production capacity of 130 GW and employs more than 33,800 people, making it the world's largest solar module supplier by shipments with a 13% global market share. Talesun, founded in 2010 as a subsidiary of China's Zhongli Science and Technology Group, operates at a considerably smaller scale with a production capacity exceeding 5 GW and a workforce of approximately 501 employees, reporting cumulative shipments of around 40 GW as of early 2025. Both manufacturers carry Tier 1 bankable status - a critical financial credibility marker for project lenders and insurers - and both are headquartered in China. Jinko has a substantially broader geographic footprint, with over 300 GW of modules installed across global markets, while Talesun has a more targeted international presence.

From a technology standpoint, both manufacturers have made TOPCon their leading cell technology, accounting for 39.4% of Jinko's 545-panel portfolio and 43.8% of Talesun's 144-panel portfolio. Both achieve the same peak efficiency of 24.8%. Jinko's portfolio averages 511 Wp per panel, while Talesun's panels average a higher 564 Wp, indicating a more concentrated focus on large-format, high-power modules well suited to utility-scale ground-mount and commercial C&I projects. Talesun also offers a notably higher proportion of bifacial panels - 59.0% of its range versus 31.9% for Jinko - along with a marginally better average temperature coefficient of -0.304%/°C compared to Jinko's -0.308%/°C, which can deliver modest energy yield advantages in warmer conditions. Warranty coverage is comparable for both, averaging just under 29 years across each portfolio.

For international buyers selecting between the two, the decision largely hinges on project scale and risk tolerance. Jinko Solar is the lower-risk choice for any project requiring well-documented bankability, a broad supply chain, and proven long-term reliability - particularly for large utility-scale or commercial installations where project financing is involved. Talesun represents a compelling alternative for buyers seeking a bifacial-heavy, high-wattage portfolio from a Tier 1 supplier, especially for ground-mounted systems where bifacial yield gains can be fully realised and where a leaner, more focused manufacturer relationship is acceptable.
