## Summary

Talesun Solar (Suzhou Talesun Solar Technologies Co., Ltd.) was founded in 2010 as a wholly owned subsidiary of Jiangsu Zhongli Group, a Shenzhen-listed conglomerate with corporate roots going back to 1988. Headquartered in Suzhou, Jiangsu Province, China, Talesun has developed a multi-gigawatt module manufacturing operation and was listed on the BloombergNEF Tier 1 Module Supplier ranking in Q1 2025. Trina Solar was founded in 1997 by Jifan Gao, is headquartered in Jiangsu Province, and established an international headquarters in Shanghai in 2022. It has maintained a continuous BloombergNEF Tier 1 status over many years and has recorded cumulative module shipments exceeding 205 GW across more than 100 countries, placing it consistently among the top-three global module suppliers. In terms of institutional depth, bankability history, and market scale, Trina Solar holds the clearly stronger standing.

Talesun addresses a wide application range - from residential rooftop systems to commercial and industrial projects and utility-scale ground-mounted farms. The company has actively expanded into European markets, delivering over 800 MW to Europe between 2021 and mid-2022, and has established meaningful volume partnerships in Poland through local distribution networks. Trina Solar serves an equally broad spectrum of end markets globally, with particular strength in utility-scale and C&I segments. The company has been a key driver of the 210mm large-format module platform, with its 210mm shipments reported to account for approximately 170 GW of the roughly 380 GW global cumulative for that format by end of 2024, underscoring its role as a technology leader in high-power modules.

For international buyers, both brands offer bankable, Tier 1-rated products backed by global distribution and competitive warranty terms. Trina Solar's longer track record, larger cumulative shipments, and deeper relationships with project finance institutions make it the lower-risk choice for large utility-scale or finance-driven procurement. Talesun is a credible mid-tier alternative that may offer competitive pricing in commercial and residential segments, particularly in markets - including Poland and parts of Western Europe - where it has already established local distribution partnerships. For buyers in those specific markets, the two are more closely matched than the headline scale difference might suggest.
