## Summary

Gamko New Energy is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu province, with roots dating to around 2008. The company reports an annual production capacity of approximately 1.2 GW and holds standard industry certifications including IEC 61215, IEC 61730, ISO 9001, and ISO 14001. Gamko does not appear on the BloombergNEF Tier 1 list, meaning its modules have not yet been rated as bankable at scale by institutional lenders. Phono Solar, headquartered in Nanjing, operates as a subsidiary of SUMEC Group, itself a member of the Fortune Global 500 SINOMACH conglomerate ranked 281st in 2023. Phono Solar has held BloombergNEF Tier 1 status continuously since 2014, reports annual production capacity of around 3 GW, cumulative global shipments exceeding 20 GW, and operates manufacturing facilities across China, Turkey, and Vietnam. On institutional standing, Phono Solar is the clear leader of the two.

Gamko's catalog spans a wide wattage range - from small portable panels to high-output modules reaching up to 800 W - across both PERC and TOPCon cell technologies, with bifacial variants also available. The brand is primarily positioned for residential rooftop, small commercial, and off-grid applications. Phono Solar serves a comparable spread of use cases - residential, commercial and industrial, and utility-scale ground-mount - anchoring its portfolio in TOPCon technology with module efficiencies ranging from 20 to 22.6 percent. Its flagship Quasar back-contact bifacial dual-glass module, announced in late 2025, reaches a module efficiency of 23.27 percent, placing it at the frontier of mass-produced crystalline silicon. Phono Solar was also named a Top Performer in Kiwa PVEL's 2025 PV Module Reliability Scorecard, providing independent third-party quality validation that is rarely available for smaller manufacturers such as Gamko.

For a typical international buyer - whether a residential installer, a C&I project developer, or a utility-scale procurer - Phono Solar is the more defensible default. Its long-standing Tier 1 status simplifies project financing, its PVEL recognition provides independent quality assurance, and its 3 GW annual capacity supports supply continuity at scale. Gamko New Energy may appeal to buyers with tighter budgets or niche requirements such as off-grid systems and portable applications, but its absence from bankability lists and limited third-party test coverage introduce meaningful uncertainty for larger financed projects. The two brands are not interchangeable where project finance is involved, though for straightforward residential cash purchases both can deliver certified, functional modules.
