Headquartered in Seongnam-si, South Korea, it holds BloombergNEF Tier 1 bankable status and operates roughly 1.4 GW of annual module production capacity, with manufacturing concentrated in South Korea. REC Group was founded in Norway in 1996 and maintains operational headquarters in Singapore; it was acquired by Indian conglomerate Reliance Industries in 2021 for approximately $771 million. REC has historically held Tier 1 status, though analysts have flagged a notable decline in module shipment volumes in recent years alongside questions about financial stability under its new ownership structure. In terms of institutional footprint and production scale, Hyundai's tighter integration within a large Korean industrial conglomerate currently gives it a more stable financial footing. On the product side, Hyundai has moved decisively into n-type TOPCon technology, having begun mass production of TOPCon cells at its Korean facilities and showcasing this lineup at RE+ 2025. Its portfolio spans residential rooftop modules through to commercial and light industrial applications. REC's brand identity, by contrast, is tightly bound to heterojunction (HJT) technology: its Alpha series - including the Alpha Pure, Alpha Pure 2, Alpha Pure-R, and the newer Alpha Pro M aimed at commercial and industrial rooftops - has been its flagship line for years. REC's HJT modules carry a notably low temperature coefficient and strong long-term degradation figures, making them attractive for space-constrained rooftops where squeezing maximum output per square meter justifies a premium cost. For most residential and small commercial buyers in 2025, Hyundai represents the safer institutional choice given its clearer production scale and corporate backing. REC remains the better pick for buyers willing to pay a premium for HJT performance characteristics, provided they are comfortable with REC's current ownership transition and market position uncertainties. \---LINKS--- \- 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/2021/03/12/hyundai-builds-1-37-gw-solar-cell-factory-in-south-korea/ \| Hyundai builds 1.37 GW solar cell factory in South Korea \| article \- https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels \| Complete Review of Hyundai Solar Panels 2025 - SolarReviews \| review \- https://www.solarreviews.com/blog/rec-solar-panels-complete-review \| 2025 Expert Review of REC Solar Panels - SolarReviews \| review \- https://www.pv-tech.org/rec-group-module-series-hjt-cells-22-5-conversion-efficiency/ \| REC Group launches module series using HJT cells - PV Tech \| article Sources: \- \[HD Hyundai Energy Solutions begins mass production of N-Type TOPCon cells\](https://pv-magazine-usa.com/press-releases/hd-hyundai-energy-solutions-begins-mass-production-of-n-type-topcon-cells/) \- \[Hyundai builds 1.37 GW solar cell factory in South Korea\](https://www.pv-magazine.com/2021/03/12/hyundai-builds-1-37-gw-solar-cell-factory-in-south-korea/) \- \[Complete Review of Hyundai Solar Panels 2025 - SolarReviews\](https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels) \- \[2025 Expert Review of REC Solar Panels - SolarReviews\](https://www.solarreviews.com/blog/rec-solar-panels-complete-review) \- \[REC Group launches module series using HJT cells - PV Tech\](https://www.pv-tech.org/rec-group-module-series-hjt-cells-22-5-conversion-efficiency/) Written by claude-sonnet from the figures above. ## Other comparisons - [Hyundai vs A.B.
