## Summary

AKCOME (formally Zhejiang Akcome New Energy Technology Co., Ltd.) is a Chinese solar manufacturer with headquarters in Zhejiang province and reported annual PV module production capacity of around 3.8 GW. The company previously held BloombergNEF Tier 1 bankability recognition, though at least one of its entities - Jiangsu AKCOME - was reportedly removed from the 2024 Tier 1 list, and its product listing on the TaiyangNews TOP MODULES index was also suspended in early 2025 due to website accessibility issues. Gamko New Energy (Nantong Gamko New Energy Co., Ltd.) is a smaller manufacturer based in Nantong, Jiangsu, founded around 2017, with annual production capacity that reached approximately 1.2 GW by 2023. Gamko self-describes as a "Tier 1 factory" on trade platforms but no confirmed BloombergNEF Tier 1 status was found in independent sources. On institutional scale and verifiable bankability history, AKCOME holds the stronger footprint of the two.

AKCOME's product range centers on high-efficiency N-type panels, notably HJT bifacial modules in the 655-700W bracket suited to commercial rooftops and utility-scale ground mounts where premium cell technology is warranted. The company has also offered PERC-based products, giving it multi-segment coverage. Gamko New Energy spans a considerably wider wattage range - from compact sub-300W panels through to larger format modules using PERC and TOPCon technology - and its export focus on markets in Europe, North America, and Asia-Pacific suggests positioning as a competitively priced, broadly certified supplier rather than a premium-tier specialist.

For buyers in 2025 evaluating utility or large commercial projects requiring bankable modules, AKCOME is the stronger starting point given its larger production scale and track record, though current Tier 1 status should be independently confirmed before non-recourse financing is arranged. Gamko New Energy is better suited to buyers prioritizing pricing flexibility and a broad product catalog for smaller commercial or off-grid applications. The two brands occupy meaningfully different tiers and are not interchangeable at scale.
