## Summary

Gamko New Energy is a Chinese solar module 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 in 2023, placing it in the small-to-mid tier of Chinese producers. No independent confirmation of BloombergNEF Tier 1 bankable status has been found for Gamko in publicly available sources. Goldi Solar, by contrast, was founded in 2011 and is headquartered in Surat, Gujarat, India. It ranks among India's largest solar module manufacturers, carries a confirmed BloombergNEF Tier 1 bankability designation, and reported annual module production capacity of approximately 14.7 GW in late 2025, with expansion to over 19 GW planned by FY2028. On institutional footprint, Goldi Solar holds a clear and substantial advantage.

Gamko's product range spans a broad wattage spectrum, from small residential panels up to higher-power commercial formats. The lineup covers PERC and TOPCon cell technologies and includes bifacial options, with CE certifications confirming compliance for European markets. Some independent field reports have flagged instances of hot-spotting and water ingress on certain larger-format models, which warrants careful model-level due diligence before specifying at scale. Goldi Solar's current portfolio is anchored in TOPCon and PERC modules, with TOPCon now forming the majority of new production output. The company also unveiled an IBC (interdigitated back-contact) module in 2025 delivering 665 W and 24.6% efficiency, positioning it at the leading edge of mainstream module technology. Its portfolio serves residential rooftop, commercial and industrial (C&I), and utility-scale ground-mount segments across more than 20 countries, backed by an AI-driven manufacturing facility.

For a typical international buyer - whether a project developer, EPC contractor, or institutional investor - Goldi Solar is the more defensible specification. Its confirmed Tier 1 bankability, far greater production scale, and technology roadmap extending into IBC cells give it a meaningful edge in project finance scenarios and long-term supply security. Gamko may suit cost-sensitive buyers for smaller-volume installations after thorough local quality checks, but the absence of confirmed bankability and the field quality reports elevate procurement risk. The two brands are not interchangeable for utility-scale or institutionally financed projects.
