## Summary

Gamko New Energy is a Chinese manufacturer headquartered in Nantong, Jiangsu province, with roots going back to approximately 2008. The company reported an annual production capacity of around 1.2 GW as of 2023 and holds standard international certifications including IEC 61215, IEC 61730, ISO 9001, and CE marking relevant to European markets. No independent confirmation of Tier 1 or BloombergNEF bankability status was found in available sources. Hanersun, based in Nanjing, China, occupies a considerably stronger institutional position - it has been officially ranked as a BloombergNEF Tier 1 module manufacturer, earned a Top Performer designation in the Kiwa PVEL 2025 PV Module Reliability Scorecard, and was recognized as Most Influential Photovoltaic Module Company at the Solarbe Solar Industry Summit in 2025. By end of 2023, Hanersun had cumulatively delivered more than 12 GW of modules to over 90 countries. On bankability and market credibility, Hanersun is clearly the stronger brand.

Gamko New Energy offers a broad portfolio covering both PERC and TOPCon cell technologies along with bifacial variants, spanning a wide power range from small residential configurations to larger ground-mount applications. This versatility makes Gamko a flexible supplier for installers who serve both the residential rooftop segment and mid-scale commercial projects requiring diverse wattage options. Hanersun centers its current commercial lineup on N-type TOPCon modules under the Hitouch series, ranging from roughly 445 W to 590 W, and has additionally introduced an ABC cell line with reported efficiencies up to 23.2 percent. Both residential, commercial and industrial, and utility-scale buyers are addressed, with bifacial dual-glass configurations being a particular strength for high-yield ground-mount environments.

For most international buyers, Hanersun is the more defensible default. Its confirmed Tier 1 bankability, third-party reliability recognition, and leading-edge cell technology simplify both project financing and long-term performance expectations. Gamko New Energy may suit buyers with tighter budgets or those requiring smaller-wattage modules outside Hanersun's primary range, but in any context where lender or investor sign-off is required, Hanersun's institutional standing gives it a clear edge.
