Middle of its segment, heavy for its output
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.

Weight-limited structures, hot climates and roofs where every square metre has to count.
Bottom 8% of the TOPCon 400-450 W segment, against a median of 51.4. Ranked 11,670th in the whole database.
Bottom 10% of the TOPCon 400-450 W segment, against a median of -0.290.
Bottom 19% of the TOPCon 400-450 W segment, against a median of 220.2.
N-type TOPCon cells exhibit virtually zero LID/LeTID effect. 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.
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.
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.
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.
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.
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.
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%).
- 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
