## Summary

Gamko New Energy (Nantong Gamko New Energy Co., Ltd.) is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu Province. The company's founding date is difficult to pin down precisely - different sources suggest production activity beginning as early as around 2008 or somewhat later. According to ENF Solar data, Gamko's annual production capacity reached approximately 1.2 GW in 2023. No evidence was found of Gamko appearing on the BloombergNEF Tier 1 list, which distinguishes it clearly from the largest global players. GCL (GCL System Integration Technology Co., Ltd.) is the module manufacturing arm of GCL Group, one of China's largest energy conglomerates, vertically integrated from polysilicon feedstock through to finished modules. GCL-SI holds confirmed BloombergNEF Tier 1 bankability status and ranks among the world's top module shippers: it shipped 16 GW of modules in 2023 and approximately 25 GW in 2024, with a nameplate capacity of around 30 GW. By any institutional measure - bankability, production scale, and project finance track record - GCL significantly outweighs Gamko.

Gamko's portfolio spans a wide power range, from a few watts up to over 800 W, covering monocrystalline, polycrystalline, flexible, and bifacial formats. The company holds CE-EMC, CE-LVD, IEC 61215, and IEC 61730 certifications, and markets its products across western Europe including Germany, France, the Netherlands, and Italy. EPR registration in Germany and France indicates compliance with European end-of-life recycling requirements. Its product line includes TOPCon and PERC technology, though independent field reviews from installers are sparse. GCL focuses on higher-wattage modules - up to approximately 680 W - oriented toward utility-scale and commercial C&I applications. The company has aggressively transitioned its lineup to n-type TOPCon cells, which now dominate its newer product series. GCL's European distribution footprint, documented by independent industry sources and distributor networks, is substantially broader and more established than Gamko's.

For international buyers - particularly those financing larger projects or needing bankable equipment - GCL is the more verifiable and lower-risk choice, backed by Tier 1 status, substantial shipping volumes, and broad independent documentation. Gamko may appeal as a cost-competitive alternative for smaller or off-grid applications, but the lack of independent third-party reviews and the absence of confirmed bankability certification mean buyers should exercise additional due diligence, including requesting up-to-date datasheets, third-party test reports, and local distributor references before committing.
