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, now operating as HD Hyundai Energy Solutions, is a South Korean manufacturer headquartered in Seongnam that traces its solar roots to Hyundai Heavy Industries' entry into the business around 2004-2005, becoming an independent listed company in 2016. The brand currently holds BloombergNEF Tier 1 bankability status, meaning major lenders will finance projects using its modules, and its annual production capacity is reported in a wide range across sources, from roughly 1.4 GW to over 4 GW depending on the period and line, with N-type TOPCon cell production starting in 2025 under licensed IP. Resun Solar is a Chinese manufacturer based in Suzhou, founded in 2005, running several factories in Jiangsu province with a combined capacity of around 1 GW per year; it does not appear on the BloombergNEF Tier 1 list, giving it a noticeably thinner institutional footprint than Hyundai.
Hyundai's module lineup is aimed primarily at residential and commercial (C&I) rooftop installations across Europe, the US, Australia and Asia, built mostly around monocrystalline cells with a growing share of TOPCon technology. Resun Solar produces both polycrystalline and monocrystalline panels, including TOPCon models ranging from 420 W to 590 W with claimed efficiencies up to about 22.9 percent, generally positioned for rooftop and smaller commercial projects in price-sensitive export markets.
For a typical buyer who needs project financing or long-term warranty assurance, Hyundai is the safer default thanks to its Tier 1 status and larger production scale. Resun Solar can be a reasonable option where upfront cost is the dominant factor and bankability requirements are less strict, but the two brands are not truly interchangeable given the gap in institutional standing, not just branding.
