Combined with 16 busbars (16BB) and half-cut cell design, the module reduces series resistance and partial-shading losses — a meaningful advantage under Poland's frequently overcast conditions. - **25-year product warranty** - The Hyundai NF(BK) series carries a 25-year materials and workmanship warranty, while a direct peer — the Luxor ECO LINE N-TYPE TOPCon NON-REFLECT 440W — offers only 15 years of product warranty. The 10-year gap represents substantially lower investment risk for residential prosumers and stronger protection across the full system lifecycle. - **30-year power warranty (≥87.4%)** - Hyundai guarantees ≥87.4% of rated output after 30 years of operation. The peer Luxor ECO LINE NON-REFLECT 440W guarantees 87.5% of rated output, but only after 25 years — Hyundai covers an additional 5-year horizon at a comparable retention level, directly improving LCOE economics for installations designed to operate beyond 25 years. - **Dual-glass construction, 5,400 Pa** - Semi-tempered 2.0 mm glass on both sides provides a mechanical load rating of 5,400 Pa front and rear. This exceeds the requirements of typical Polish residential rooftop installations (normative 2,400 Pa per PN-EN 1991-1-3), making the module well-suited for high-snowfall or high-wind regions such as the Sudetes or Tatra mountains. - **Temperature coefficient Pmax -0.30%/°C** - A temperature coefficient of -0.30%/°C is significantly better than standard PERC cells (-0.35% to -0.40%/°C) and matches leading peers (Luxor -0.30%/°C, Seraphim Nebula). At a typical summer module temperature of ~60°C (25°C above STC), power losses amount to only 10.5% vs ~12.25% for a typical PERC module — a measurable real-world gain during Polish summer heat. ## Cons - **Peak efficiency 22.53% vs Luxor 22.86%** - The series' maximum efficiency (22.53%) trails a direct peer — the Luxor ECO LINE N-TYPE TOPCon NON-REFLECT 440W (22.86%) — by 0.33 percentage points. On a constrained roof area (e.g., 20 m²), this gap translates to ~14 Wp less per module; for a typical 10 kWp system on a very small roof, it could necessitate 1–2 additional modules to meet the same power target. - **Limited bifacial gain on dark roofs** - The NF(BK) Full Black variant specifically targets aesthetically dark rooftiles — yet dark roof surfaces carry an albedo of only 10–20%, capping practical rear-side energy gain at 3–5% of rated output. By contrast, light-colored substrates (white membrane, bright gravel) with 40–70% albedo deliver 10–20% bifacial gain. Buyers prioritizing maximum bifacial yield should factor this trade-off into system design. ## About this series Hyundai photovoltaic panels from the NF(BK) series are based on innovative **shingled technology**, which redefines the standards of durability and aesthetics in modern solar energy. By eliminating traditional busbars and replacing them with overlapping cells, these modules offer a significantly larger active surface area and minimize the risk of micro-cracks under mechanical loads. This series is characterized by **exceptional Full Black aesthetics**, making it the first choice for demanding residential users who wish to harmoniously blend the installation with dark roofing. The use of shingled technology allows for **maximum efficiency in shaded conditions** and better performance in low sunlight, which directly translates into higher energy yields in the Polish climate. NF(BK) modules solve the problem of limited installation space, delivering more power from the same area than standard panels. The security of the investment is highlighted by a **25-year product warranty**, which covers both workmanship and linear power output. This is an uncompromising solution for those seeking a combination of modern design and industrial reliability, standing out from the competition with a longer lifespan and higher resistance to degradation caused by atmospheric factors. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 222.8 W/m² matches the \*\*TOPCon 400-450W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - Weight of 24.5 kg is 2.5 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is shingled cell technology in the Hyundai NF(BK) Series and what advantages does it offer? Shingled technology involves overlapping cells bonded with conductive adhesive instead of conventional busbars. In the NF(BK) series this eliminates the micro-crack risk caused by mechanical stress and increases the active cell area. The result is higher output power within the same module footprint and improved performance under partial shading — a meaningful benefit on rooftops with chimneys or dormers. ### What warranty comes with the Hyundai NF(BK) Series panels? Hyundai provides a 25-year product warranty covering workmanship and materials, plus a 30-year linear power output warranty. At year 30, NF(BK) modules retain at least 87.4% of their rated power. Both warranties are backed by a South Korean Tier 1 manufacturer, significantly reducing the risk of after-sales support gaps over the module's lifetime. ### Does the bifacial design of the Hyundai NF(BK) panel make sense on a typical pitched residential roof? The 80% bifacial factor delivers meaningful yield gains mainly in ground-mount or flat-roof installations with light-colored surfaces where the rear side captures reflected irradiance. On a pitched roof with dark tiles, rear-side contribution will be marginal. The primary value of the NF(BK) series in such conditions comes from the high TOPCon cell efficiency (22.53%) and superior low-light performance. ### How do TOPCon cells in the Hyundai NF(BK) differ from common PERC cells? TOPCon (Tunnel Oxide Passivated Contact) cells use an N-type silicon substrate, which has a lower temperature coefficient and slower long-term degradation than P-type PERC cells. In practice, TOPCon modules lose less power on hot days and age more slowly — which is why Hyundai extends the power warranty on the NF(BK) to 30 years, compared to the 25-year standard typically offered for PERC modules. ### Does the Hyundai NF(BK) 440 Wp Full Black panel integrate visually with a dark roof? Yes, the NF(BK) series was designed specifically for integration with dark roofing. The black frame, black backsheet, and dark cells create a uniform all-black appearance. At up to 440 Wp per module, fewer panels are needed to reach the target system size, further simplifying the roof's visual composition. It is one of the few TOPCon modules combining a Full Black finish with a bifacial glass-glass construction. ### How do Hyundai NF(BK) panels perform in overcast conditions and low temperatures typical of Central Europe? N-type TOPCon cells demonstrate superior low-light performance compared to older PERC technology, translating into higher energy yields on cloudy days common in Central European climates. The dual-glass construction improves resistance to moisture ingress and snow loads, while certifications for salt mist corrosion (IEC 61701) and ammonia resistance (IEC 62716) confirm durability across variable weather conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Hyundai_430-440w_solar_panel_Datasheet-8c5562bfc5aa.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [Hyundai HIE-S390VG](https://comparepv.com/panel/hyundai-hie-s390vg) | 390 W | -45 W, -2.4 pp, -5 yr warranty | | [Hyundai HIE-S395VG](https://comparepv.com/panel/hyundai-hie-s395vg) | 395 W | Hotter, -2.1 pp, -5 yr warranty | | [Hyundai HIE-S400VG](https://comparepv.com/panel/hyundai-hie-s400vg) | 400 W | Hotter, -1.9 pp, -5 yr warranty | | [Hyundai HIE-S405VG](https://comparepv.com/panel/hyundai-hie-s405vg) | 405 W | Hotter, -1.6 pp, -5 yr warranty | | [Hyundai HIE-S410VG](https://comparepv.com/panel/hyundai-hie-s410vg) | 410 W | Hotter, -1.4 pp, -5 yr warranty | | [Hyundai HiT-H425MF-FB](https://comparepv.com/panel/hyundai-hit-h425mf-fb) | 425 W | Cooler, lighter, -0.5 pp | | [Hyundai HiT-H430MF-FB](https://comparepv.com/panel/hyundai-hit-h430mf-fb) | 430 W | Cooler, lighter, -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/hyundai-hin-t435nf-bk Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
