Catalogue against catalogue
An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary
Hyundai Energy Solutions is the solar division of South Korea's Hyundai conglomerate, with manufacturing rooted in Korea and an annual production capacity reported at over 1.4 GW. The brand holds BloombergNEF Tier 1 bankability status, meaning institutional lenders routinely finance projects built around its modules. Sunman Energy, founded in 2014 and headquartered in Shanghai, China, is a considerably smaller specialist outfit focused entirely on its proprietary glass-free eArc composite-panel technology. Sunman does not appear on published BloombergNEF Tier 1 lists, and no verified GW-scale production figure is publicly available for the company. On institutional footprint and supply-chain depth, Hyundai holds a clear advantage.
The two brands occupy almost non-overlapping niches. Hyundai Energy Solutions serves mainstream residential and commercial rooftops with conventional framed modules, and WebSearch-confirmed specs point to N-type TOPCon and shingled cell variants reaching efficiencies in the 20.5-20.6% range, backed by product and performance warranties of up to 30 years. Sunman's eArc panels are glass-free, polymer-composite modules weighing roughly 70% less than standard glass panels, with efficiencies confirmed by pv-magazine at up to 19.3%. Their target markets are structurally limited commercial and industrial rooftops that cannot bear a conventional racking system, as well as BIPV, vehicle-integrated, balcony, and off-grid applications - segments where no framed module can compete.
For a typical homeowner or standard commercial installer in 2025, Hyundai Energy Solutions is the more straightforward choice: bankable, widely distributed, competitively priced, and covered by long warranties from a financially stable parent. Sunman is not a like-for-like alternative - it fills a genuine technical gap where weight or flexibility constraints rule out conventional modules, and buyers willing to pay a premium for that capability will find it uniquely suited to those edge cases.
