It is a comparatively small, innovation-focused company - not listed among BloombergNEF Tier 1 manufacturers - with partial French manufacturing at its Jujurieux assembly plant and cell sourcing from China. Hyundai Energy Solutions, operating under the HD Hyundai group, is a South Korean manufacturer with a substantially larger global footprint, serving residential, commercial, and utility-scale markets across multiple continents. Hyundai was previously recognized on the BloombergNEF Tier 1 list, though search results from mid-2025 indicate it was dropped from that list due to non-compliance with updated BNEF bankability criteria. In terms of institutional scale and international supply chain depth, Hyundai carries the broader market presence. DualSun's product offering centers on two distinct lines: the FLASH range, a pure photovoltaic module using shingle cell technology with confirmed efficiencies between roughly 21.6% and 22.8%, aimed at aesthetically conscious residential rooftops; and the SPRING range, a patented hybrid photovoltaic-thermal panel that simultaneously generates electricity and domestic hot water, making it uniquely suited to homes seeking to offset both electricity and heating costs in a single roof footprint. Hyundai's catalog is broader, spanning older PERC-based residential modules and a growing lineup of N-type TOPCon bifacial panels - including the NF(BK) series and the high-wattage HiN-T commercial modules - covering applications from standard rooftop residential to large commercial ground mounts. For a typical buyer in 2025, the two brands serve genuinely different needs rather than competing directly. DualSun is the stronger choice for homeowners who want hybrid thermal-electric output or premium all-black aesthetics and are willing to pay a premium for French-assembled innovation. Hyundai suits buyers looking for a well-established, value-positioned brand with a wide product range and reliable N-type TOPCon efficiency across residential and commercial scales - provided the installer can confirm current supply and warranty support given the brand's recent change in BNEF status. \---LINKS--- \- https://www.pv-magazine.com/2021/02/18/dualsun-unveils-375-w-photovoltaic-thermal-panel-with-shingle-tech/ \| DualSun unveils 375 W photovoltaic-thermal panel with shingle tech \| article \- https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels \| Complete Review of Hyundai Solar Panels in 2025 - SolarReviews \| review \- https://www.energysage.com/solar/best-solar-panels-complete-ranking/hyundai-solar-panels-complete-review/ \| Hyundai Solar Panels - Complete Review - EnergySage \| review \- https://www.ecowatch.com/solar/best-companies/hyundai-solar-panels \| Hyundai Solar Panels Review - Cost, Ratings and Reviews 2026 \| review \- https://energypal.com/best-solar-panels-for-homes/dualsun \| DualSun - Best Solar Panels for Homes 2025 - EnergyPal \| review Sources: \- \[DualSun unveils 375 W photovoltaic-thermal panel with shingle tech - PV Magazine\](https://www.pv-magazine.com/2021/02/18/dualsun-unveils-375-w-photovoltaic-thermal-panel-with-shingle-tech/) \- \[Complete Review of Hyundai Solar Panels in 2025 - SolarReviews\](https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels) \- \[Hyundai Solar Panels - Complete Review - EnergySage\](https://www.energysage.com/solar/best-solar-panels-complete-ranking/hyundai-solar-panels-complete-review/) \- \[Hyundai Solar Panels Review - EcoWatch\](https://www.ecowatch.com/solar/best-companies/hyundai-solar-panels) \- \[DualSun - Best Solar Panels for Homes 2025 - EnergyPal\](https://energypal.com/best-solar-panels-for-homes/dualsun) Written by claude-sonnet from the figures above. ## Other comparisons - [DualSun vs A.B.
