## Summary

Gamko New Energy is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu Province, with roots traceable to approximately 2008, though some company materials suggest a later operational start date. Its annual production capacity reached around 1.2 GW in 2023, placing it in the small-to-mid tier of global module makers. Gamko does not appear on the BloombergNEF Tier 1 module maker list, which limits its bankability for project-financed installations. Talesun Solar, by contrast, is a subsidiary of Zhongli Science and Technology Group - a Chinese industrial conglomerate founded in 1988 - and was established in 2010. Talesun holds a confirmed position on the BloombergNEF Q1 2025 Tier 1 list, reports cumulative shipments of approximately 40 GW by early 2025, and operates annual module production capacity in the range of 2.8 GW. On institutional footprint alone, Talesun holds a decisive lead.

Gamko's catalog spans a wide power range - from small off-grid formats around 5 W up to high-power 700-720 W utility modules - and includes bifacial and flexible panel variants. The company has confirmed deployment of both PERC and TOPCon cell technologies, and its IEC 61215, IEC 61730, and CE certifications meet European market entry requirements. Independent installer feedback and third-party reliability data remain scarce, however. Talesun's flagship BISTAR series uses monocrystalline PERC half-cut cells and covers the full application spectrum, from residential rooftop formats starting around 360 W through commercial and industrial projects to utility-scale ground-mount configurations at 670 W and above. The brand performed strongly across all six reliability categories in PV Evolution Labs' 2023 testing and is actively distributed across Europe, North America, South America, and Australia.

For most international buyers - residential installers, C&I developers, or utility-scale procurers - Talesun is the more defensible default. Its BloombergNEF Tier 1 status satisfies typical project finance covenants, its deployment record provides meaningful field data, and independent testing supports its reliability claims. Gamko may serve budget-focused buyers seeking certified modules for smaller off-grid or straightforward grid-tied systems, but its absence from Tier 1 lists and limited third-party track record introduce meaningful uncertainty for larger or financed projects. The two brands are not interchangeable where bankability is a requirement.
