The company launched its solar business in 2004 as part of the broader HD Hyundai industrial group and became an independent publicly listed corporation in 2016. It holds BloombergNEF Tier 1 bankability status and carries annual production capacity of over 1.4 GW. VSUN is a solar module provider headquartered in Tokyo, Japan, backed by Fuji Solar and recently acquired by Toyo Co., Ltd.; it has held BloombergNEF Tier 1 status for most quarters since Q3 2019, and its Vietnamese manufacturing site alone accounts for a reported 4 GW of module capacity. On institutional footprint and brand recognition - particularly in North American and European project-finance circles - Hyundai's decades-long conglomerate backing gives it a modest but real edge. Both brands have converged on N-type TOPCon as their primary cell technology, with PERC-based lines still available in each portfolio. Hyundai's product range covers residential all-black half-cut panels in the mid-400W class (the NF(BK) series is their current flagship for rooftops) through to large-format bifacial commercial modules above 640W; the company earned PVEL Top Performer recognition in its 2025 scorecard for thermal cycling, hail stress, and PID resistance. VSUN's catalog spans from roughly 390W up to 715W, with bifacial TOPCon modules dominating the current lineup and the brand earning PVEL Top Performer status for five consecutive years from 2021 to 2025. VSUN also has a US-based manufacturing subsidiary (Toyo Solar) targeting a 2 GW domestic capacity, which is relevant for buyers who need modules that qualify under domestic-content incentives. For a typical residential buyer in 2025, Hyundai is the safer default where installer familiarity and long-term brand support matter most. For commercial or utility buyers who prioritize documented efficiency, bifacial output gains, and domestic-content eligibility in the US, VSUN's broader high-wattage TOPCon range and emerging American production make it a compelling alternative. The two brands are more similar than different in technology and warranty posture; the decision usually comes down to installer availability and project-finance requirements in a given market. \---LINKS--- \- https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels \| Complete Review of Hyundai Solar Panels in 2025 - SolarReviews \| review \- https://pv-magazine-usa.com/press-releases/hd-hyundai-energy-solutions-begins-mass-production-of-n-type-topcon-cells/ \| HD Hyundai Energy Solutions begins mass production of N-Type TOPCon cells \| article \- https://www.pv-magazine.com/2021/01/04/vsun-to-build-4-gw-panel-factory-in-vietnam/ \| Vsun to build 4 GW panel factory in Vietnam - pv magazine \| article \- https://solartechonline.com/blog/vsun-solar-panel-review-2025/ \| VSUN Solar Panel Review 2025 - Expert Analysis and Real Performance \| review \- https://comparepv.com/reviews/vsun \| VSUN Solar Panels Review 2026 - ComparePV \| review Sources: \- \[Complete Review of Hyundai Solar Panels in 2025 - SolarReviews\](https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels) \- \[HD Hyundai Energy Solutions begins mass production of N-Type TOPCon cells\](https://pv-magazine-usa.com/press-releases/hd-hyundai-energy-solutions-begins-mass-production-of-n-type-topcon-cells/) \- \[Vsun to build 4 GW panel factory in Vietnam - pv magazine\](https://www.pv-magazine.com/2021/01/04/vsun-to-build-4-gw-panel-factory-in-vietnam/) \- \[VSUN Solar Panel Review 2025 - SolarTechOnline\](https://solartechonline.com/blog/vsun-solar-panel-review-2025/) \- \[VSUN Solar Panels Review - ComparePV\](https://comparepv.com/reviews/vsun) Written by claude-sonnet from the figures above. ## Other comparisons - [Hyundai vs A.B.
