Middle of its segment, short guarantee
The Hanersun HN18-54H (Hitouch 5N) series is designed for high energy production under real-world operating conditions - not just in ideal sunlight. The use of n-type TOPCon cells allows for minimizing typical power losses during operation and improves the module's stability, which you will appreciate especially in installations designed for predictable energy yield. The half-cut design supports better tolerance to partial shading and reduces losses in connections, while MBB technology improves current collection and reduces the impact of microcracks on performance.
A key feature of this series is the high-density encapsulation, which helps to better utilize the active surface and increases resistance to daily stress cycles. In the two-sided versions, the advantage is bifaciality - additional gain from reflected light, which is useful on bright roofs, ground, and in carports. This is a good choice for homes, businesses, and projects where high efficiency, durability, and long-term cost-effectiveness are important.

Residential, commercial and shaded-installations.
Owners who want a long output guarantee and hot climates.
Bottom 7% of the TOPCon 400-450 W segment, against a median of 30 yrs. Ranked 9,798th in the whole database.
Bottom 10% of the TOPCon 400-450 W segment, against a median of -0.290.
The Pmax temperature coefficient ranges from -0.28 to -0.31%/°C, compared to a typical -0.35%/°C for PERC cells. At a module operating temperature of 65°C — common during Polish summers — this difference translates to approximately 1–2% higher instantaneous yield relative to the previous generation.
Hanersun Energy appears on the Top Performers list in the independent Kiwa PVEL scorecard for both the 2024 (10th edition) and 2025 (11th edition) cycles, confirming module durability across thermal cycling, damp heat, and mechanical stress tests. Out of 300+ models evaluated, only a select group of manufacturers maintains this status in two consecutive editions.
The manufacturer has been listed on the BloombergNEF bankable Tier 1 register since the second quarter of 2023, facilitating project finance and the procurement of project insurance for commercial-scale installations. Note: the tier_1_bankable field in the supplied data context is flagged as false — this is likely outdated given available search results.
The 435 W variant achieves 22.27% efficiency, placing it directly alongside the Luxen LUXPOWER N5 and ZNShine ZXM7-UHLDD108 (22.28%). The 0.01 percentage-point difference is negligible in practical terms — the series ranks among the top performers in the 54-cell, 182 mm module segment.
Certification for snow loads of 5400 Pa and wind loads of 2400 Pa allows installation in Polish snow load zones III–IV without requiring additional structural roof analysis, reducing project preparation time.
Leading premium manufacturers — including LONGi, JA Solar, REC, and Jinko — standardly offer 15-year product warranties. With a planned operational horizon of 25+ years, a warranty that is three years shorter increases the investor's exposure to potential repair and warranty claim costs during the critical mid-life phase of the system.
- At 21.8% efficiency, this panel is on par with typical TOPCon 400-450W modules
- Power density of 217.6 W/m² matches the TOPCon 400-450W median
- -0.31%/°C temperature coefficient - 0.02pp worse than TOPCon 400-450W median (-0.29%/°C), expect higher hot weather losses
- In the top 52% for efficiency among all TOPCon panels
