The manufacturer's warranty caps annual power loss at 0.4% (years 2–30), ensuring retention of >88% of rated power after 30 years — more favorable than typical PERC modules, where degradation reaches 0.45–0.55%/year. - **Bifacial design – additional yield from reflected irradiance** - The bifacial construction captures 5–15% additional energy from irradiance reflected off high-albedo surfaces (white gravel, TPO membrane, light-colored metal roofing). Particularly advantageous in installations with a ground clearance of ≥20 cm. - **Kiwa PVEL Top Performer 2025** - Hanersun Energy earned Top Performer status in the 10th edition of the Kiwa PVEL PV Module Reliability Scorecard (2025), confirming module reliability across independent mechanical stress, thermal cycling, and damp heat tests — a meaningful credential over a 30-year investment horizon. - **Efficiency up to 22.28% – at the forefront of the segment** - The maximum efficiency of 22.28% is on par with the best peer comparables in the Full Black N-type segment: Luxen LUXPOWER N5 (22.28%), ZNShine ZXM7-UHLDD108 (22.28%), and Solitek SOLID Blackstar (22.27%). The series is not outperformed by any direct competitor in this regard. - **30-year product and power output warranty** - The manufacturer provides a 20-year product warranty and a 30-year linear power output warranty — standard in the premium TOPCon segment, but less common among smaller non-Tier-1 manufacturers. This extends the safe operational horizon compared to the typical 25-year power warranties offered for PERC modules. ## Cons - **No current BNEF Tier 1 bankable status** - Despite a historical listing on the BNEF Tier 1 index in Q2 2023 (for 600W+ modules), the HN18N-54HT series (415–435 W, residential/small commercial segment) is not covered by current bankable status. For projects requiring project finance or bankability guarantees, this may be a barrier compared to modules from Trina, JA Solar, or Canadian Solar. - **Dark backsheet reduces bifacial gain** - The Full Black finish involves a dark backsheet or dark rear glass, which absorbs a portion of reflected irradiance and lowers the bifacial factor relative to standard bifacial modules with a transparent backsheet. In practice, the real additional bifacial yield will be closer to the lower end of the range (5–8%) rather than the upper end (12–15%). ## About this series The Hanersun Hitouch 5N HN18N-54HT (Full Black) series is designed for maximum energy production on the roof, without compromising aesthetics. The modules utilize N-type cells in TOPCon technology, offering stable performance over a long period and very good efficiency even in less sunny conditions. The use of a **bifacial design** allows for the recovery of additional energy from reflected light, which significantly improves performance in installations on reflective surfaces or with greater open space compared to traditional roof tiles. Compared to the competition, it stands out due to its **full black finish** (consistent, dark color scheme), which complements modern architecture. The high cell density, along with **MBB and half-cut technology**, minimize losses and improve resistance to microcracks, while a refined electrical design reduces the risk of hot spots. This is a smart choice for customers who want **high efficiency in real-world conditions** - in residential installations, small businesses, and premium projects, where appearance, reliability, and predictable performance are important. ## Notable figures - Efficiency of 21.5% matches the \*\*TOPCon 400-450W\*\* median - At 215.1 W/m², this panel generates 5.1 W/m² less per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - -0.31%/°C temperature coefficient - 0.02pp worse than \*\*TOPCon 400-450W\*\* median (-0.29%/°C), expect higher hot weather losses - At 24.5 kg (2.5 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What sets the Hanersun Hitouch 5N HN18N-54HT Full Black apart visually, and does it suit a modern rooftop? The HN18N-54HT Full Black variant features an all-black design — black cells, frame, and backsheet — making it a natural fit for modern residential and premium architectural projects where standard silver-framed panels would stand out. The module dimensions are 1722 × 1134 mm, compatible with most standard racking systems. ### Does the bifacial design of the Hanersun HN18N-54HT actually boost energy production in a real rooftop installation? Yes. The module has a bifaciality factor of 80% (±5%), meaning the rear side can harvest up to 80% of the front-side power from reflected irradiance. The gain is most significant on high-albedo surfaces such as white membranes, concrete, or gravel, and when there is adequate clearance from the roof surface. In typical rooftop installations the real-world yield gain is a few percent. ### What warranties come with the Hanersun Hitouch 5N HN18N-54HT solar panels? Hanersun provides a 20-year product warranty covering defects and workmanship, plus a 30-year linear power output warranty. Annual power degradation after the first year is guaranteed at no more than 0.4%, ensuring stable generation throughout the system's lifetime. This degradation rate is among the best available for TOPCon-class modules. ### How does the TOPCon cell technology in the Hanersun HN18N-54HT compare to older PERC technology? N-type TOPCon cells feature a thin passivation contact layer on the rear side that reduces carrier recombination, enabling a peak efficiency of 22.8% under STC — higher than typical PERC. N-type cells are also significantly less prone to LID (Light-Induced Degradation) and retain better performance at elevated cell temperatures, resulting in higher annual energy yield per square meter of roof space. ### How do Hanersun HN18N-54HT panels perform in winter and under overcast skies? N-type TOPCon technology provides a superior temperature coefficient and better low-light sensitivity compared to PERC modules. Lower cell temperatures in winter actually increase output above STC-rated power. The 182 mm half-cut cell design combined with MBB busbars minimizes mismatch losses under partial shading — an important advantage in Central European irradiance conditions. ### What is the peak power of the Hanersun HN18N-54HT, and how many panels are needed for a home installation? The module's peak power is 435 Wp (the series spans 420–445 Wp). A typical 6 kWp residential system requires approximately 14 modules, while a 10 kWp system needs around 23 panels. At 1722 × 1134 mm, the high power density makes this series a practical choice when usable roof area is limited. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18N-54HT430W-All-Black-Double-Glass-Varus-c2812954478e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +45 W, lighter, +2.3 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, cooler, +2.3 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +50 W, +2.2 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +2.1 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +40 W, lighter, +2.1 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +2.1 pp | | [Hanersun HN18-54HB385W](https://comparepv.com/panel/hanersun-hn18-54hb385w) | 385 W | Hotter, -1.8 pp, -5 yr warranty | | [Hanersun HN18-54HB390W](https://comparepv.com/panel/hanersun-hn18-54hb390w) | 390 W | Hotter, -1.5 pp, -5 yr warranty | | [Hanersun HN18-54H395W](https://comparepv.com/panel/hanersun-hn18-54h395w) | 395 W | Hotter, -1.3 pp, -5 yr warranty | | [Hanersun HN18-54HB400W](https://comparepv.com/panel/hanersun-hn18-54hb400w) | 400 W | Hotter, -1.0 pp, -5 yr warranty | | [Hanersun HN18-54H405W](https://comparepv.com/panel/hanersun-hn18-54h405w) | 405 W | Hotter, -0.8 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +75 W, cooler, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +70 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +80 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/hanersun-hn18n-54ht420w 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.
