The company produces modules at its Korean facilities, making it one of the few non-Chinese Tier 1 manufacturers actively supplying the residential and commercial market globally. Thornova Solar, by contrast, was founded in 2022 and is headquartered in Fremont, California, operating as an independent subsidiary of China-based Sunova Solar Technology. Despite its youth, Thornova was added to BloombergNEF's Tier 1 module manufacturer list in Q3 2023 and had shipped a reported 7.1 GW of cumulative modules worldwide by the end of 2024, reflecting rapid commercial traction. On institutional depth and operating history, Hyundai holds the clear advantage. Hyundai's current lineup focuses on residential and light commercial rooftops, with its XG and NF series using half-cut monocrystalline cells and, more recently, N-type TOPCon technology - module efficiencies in these lines reach into the low-to-mid 22% range, and performance warranties extend to 25-30 years. Thornova's portfolio spans a wider wattage band, from roughly 400W to over 600W, covering residential through utility-scale ground-mount applications. Its Tangra N-type TOPCon modules earned Kiwa PVEL 2025 Top Performer recognition, and the company emphasizes bifacial glass-glass construction suited to demanding outdoor environments. For a typical residential buyer in 2025, Hyundai is the safer choice when brand familiarity and long institutional credibility are priorities. Thornova is a credible alternative - particularly for commercial or utility-adjacent buyers seeking higher-wattage bifacial modules at competitive pricing - but its shorter operating history warrants additional due diligence on local installer support and warranty backstop strength. \---LINKS--- \- https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels \| Complete Review of Hyundai Solar Panels in 2025 - SolarReviews \| review \- https://news.energysage.com/hyundai-solar-panels-complete-review/ \| Hyundai Solar Panels: The Complete Review - EnergySage \| 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 \| article \- https://www.pv-magazine.com/press-releases/thornova-solar-ranked-as-bnef-tier-1-module-manufacturer/ \| Thornova Solar ranked as BNEF Tier 1 module manufacturer - PV Magazine \| article Sources: \- \[Complete Review of Hyundai Solar Panels in 2025\](https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels) \- \[Hyundai Solar Panels: The Complete Review - EnergySage\](https://news.energysage.com/hyundai-solar-panels-complete-review/) \- \[HD Hyundai Energy Solutions begins mass production of N-Type TOPCon\](https://pv-magazine-usa.com/press-releases/hd-hyundai-energy-solutions-begins-mass-production-of-n-type-topcon-cells/) \- \[Thornova Solar ranked as BNEF Tier 1 module manufacturer\](https://www.pv-magazine.com/press-releases/thornova-solar-ranked-as-bnef-tier-1-module-manufacturer/) Written by claude-sonnet from the figures above. ## Other comparisons - [Hyundai vs A.B.
