Written summary
Hounen Solar is a US-based manufacturer founded in 2022 and headquartered in Orangeburg, South Carolina, where it operates an assembly facility targeting around 1 GW of annual production capacity, with stated plans to scale to 3 GW. The company is a relatively new entrant and does not appear on current BloombergNEF Tier 1 lists. Hyundai Energy Solutions - now branded HD Hyundai Energy Solutions - is a South Korean manufacturer that launched its solar business in 2004 and became an independent corporation in 2016, with its main module factory in South Korea's North Chungcheong Province and approximately 1.4 GW of annual production capacity. Hyundai carries confirmed Tier 1 bankability status backed by a well-established parent conglomerate, giving it a significantly stronger institutional footprint than Hounen.
Hounen Solar's product range runs from 400 W residential panels up to 720 W utility-scale modules, with a focus on bifacial designs assembled in the US - a meaningful advantage for buyers seeking domestic content compliance under the Inflation Reduction Act. Cell technology includes PERC configurations, and the company offers a 12-year product warranty alongside a 25-year performance guarantee. Hyundai Energy Solutions offers two main residential lines - the XG Series and the YH Series - using HJT and N-type TOPCon cell technology on premium models, with efficiencies reported up to around 22.28%, and warranties of 25 years on both product and performance, with select models offering up to 30-year coverage and an annual degradation rate of just 0.4%.
For most buyers in 2025, Hyundai Energy Solutions is the safer default - its Tier 1 status, longer track record, superior warranty terms, and advanced cell technology justify confidence for both residential and commercial installations. Hounen Solar is, however, a compelling alternative for US projects requiring domestic content qualification, where its South Carolina assembly can unlock IRA incentives unavailable to most imported panels.
