The company operates smart factory facilities in South Korea, including a cell production site with a reported capacity of around 1.37 GW, and exports panels to Europe, North America, Australia, and Asia. Independent review platforms and distributors generally describe it as a bankable, institutionally credible supplier, though it sits outside the top tier of Chinese volume producers by scale. Selfa GE is a Polish manufacturer headquartered in Szczecin whose corporate roots trace back to 1932 as an electric heating element producer. The company expanded into photovoltaics in 2004 and launched an automated PV module line in 2012, positioning itself as one of the leading PV module producers in Poland. Selfa operates at a distinctly regional scale and does not appear on the BloombergNEF bankability lists reviewed, whereas Hyundai's broader institutional presence gives it the stronger international footprint. Hyundai Energy Solutions offers several residential and light-commercial product families, including the XG Series and the newer NF(BK) Series, with its current lineup based on N-type TOPCon and PERC cell technologies. Rated efficiencies on newer models reach into the low-to-mid 22 percent range, and the company backs products with a 25-year product warranty paired with a 25-year performance guarantee, which is competitive with mainstream global brands. Selfa's catalogued modules, such as the SV60P and STP315 lines, are more modest in output and efficiency and appear to reflect PERC-era or earlier cell technology. Selfa's natural use case is regional Polish and Central European installations where local sourcing, domestic supply chain reliability, or EU-origin compliance requirements are a priority. For a typical buyer in 2025 outside of Poland, Hyundai Energy Solutions is the stronger default choice, offering globally distributed after-sales support, higher-efficiency options, and broader installer familiarity. Selfa is a defensible pick for buyers in Poland or Central Europe who specifically value a domestically manufactured product, but it cannot match Hyundai's reach, certified efficiency levels, or international warranty infrastructure. \---LINKS--- \- 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 in 2025 - SolarReviews \| review \- https://www.energysage.com/solar/best-solar-panels-complete-ranking/hyundai-solar-panels-complete-review/ \| Hyundai Solar Panels - The Complete Review - EnergySage \| review \- https://www.selfa-pv.com/en/About-us,7 \| About Selfa PV - Polish PV module manufacturer \| article \- https://www.enfsolar.com/selfa \| Selfa GE S.A. solar panel manufacturer profile - ENF Solar \| article Sources: \- \[Hyundai builds 1.37 GW solar cell factory in South Korea\](https://www.pv-magazine.com/2021/03/12/hyundai-builds-1-37-gw-solar-cell-factory-in-south-korea/) \- \[Complete Review of Hyundai Solar Panels in 2025 - SolarReviews\](https://www.solarreviews.com/blog/complete-review-hyundai-solar-panels) \- \[Hyundai Solar Panels - The Complete Review - EnergySage\](https://www.energysage.com/solar/best-solar-panels-complete-ranking/hyundai-solar-panels-complete-review/) \- \[About Selfa PV - Polish PV module manufacturer\](https://www.selfa-pv.com/en/About-us,7) \- \[Selfa GE S.A. solar panel manufacturer profile - ENF Solar\](https://www.enfsolar.com/selfa) Written by claude-sonnet from the figures above. ## Other comparisons - [Hyundai vs A.B.
