## Summary

Gamko New Energy is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu Province, formally established in 2017, though the company cites manufacturing experience dating back to 2008. Its annual production capacity reached 1.2 GW as of 2023, placing it in the mid-tier segment of Chinese producers. Gamko does not appear on published BloombergNEF Tier 1 bankability lists, which means project financiers and EPC contractors working on larger installations may require additional due diligence when specifying this brand. HD Hyundai Energy Solutions, operating under the broader HD Hyundai conglomerate, is a South Korean manufacturer with roots in the solar industry since 2004 - widely recognized as Korea's first major photovoltaic producer. The company maintains annual production capacity of approximately 1.4 GW, holds confirmed BloombergNEF Tier 1 status, and has operated a dedicated PV R&D center since 2012. On institutional footprint and market credibility, HD Hyundai Energy Solutions holds a clear advantage.

Gamko's product range spans from 5 W portable panels to 800 W large-format modules, utilizing PERC and TOPCon cell technologies alongside flexible and bifacial variants. The portfolio is oriented toward export markets including Africa, the Middle East, and Eastern Europe, with use cases ranging from off-grid rural electrification to small grid-tied residential systems. The company advertises module efficiencies up to 23-24% and a 30-year warranty, though independent long-term field data is sparse. HD Hyundai targets residential rooftop and commercial-and-industrial segments through its XG series (350-375 W, PERC) and bifacial YH series (385-410 W), with independently verifiable efficiencies of 19.3-20.6%. Since 2024 the company has moved into mass production of N-type TOPCon cells exceeding 24% efficiency, while also scaling up HJT production and pursuing perovskite-HJT tandem R&D. Its product and performance warranty stands at 25 years.

For most international buyers - residential, C&I, or smaller utility-scale projects requiring project finance - HD Hyundai Energy Solutions is the lower-risk default, backed by bankability credentials, an established European distribution network, and a well-documented technology roadmap. Gamko is a viable cost-oriented option for budget-sensitive projects or markets where price competitiveness outweighs bankability requirements, but buyers should factor in the absence of Tier 1 status and the limited pool of independent installation reviews when assessing long-term performance risk.
