The SMBB (Super Multi-Busbar) design further reduces series resistance and the risk of microcracks, extending the system's service life. - **Premium-Class Efficiency: Up to 22.65%** - The maximum module efficiency of 22.65% is on par with the top peer comparable Q-SUN Solar Qrystal N8 (22.65%) and surpasses the Risen RSM144-9-560-585BNDG (22.6%). The Pmax temperature coefficient of -0.31%/°C limits power output losses on hot days compared to PERC modules (~-0.35%/°C). - **PVEL Top Performer 2024 and 2025** - Hanersun Energy earned Top Performer recognition in both the 10th and 11th editions of the Kiwa PVEL PV Module Reliability Scorecard — an independent module reliability assessment. The company is among the few manufacturers outside the top ten by market share to hold this distinction for two consecutive years, confirming consistent production quality. - **Power Warranty Up to 30 Years (>80% Pnom)** - The best variants in the series offer a 30-year linear power warranty maintaining >80% of nominal power output, backed by a 15-year product warranty. Standard mid-tier peer comparables typically operate at 25 years / 84.8% — the extended warranty horizon lowers LCOE in projects with long financing tenors. - **Certified Mechanical Load Resistance of 5,400 Pa** - The modules are certified for a 5,400 Pa static front-side load, meeting the requirements of Snow Load Zone IV per PN-EN 1991-1-3 and extreme wind exposure categories. This qualifies the modules for installation in challenging locations without additional structural reinforcement. ## Cons - **No Bankable Tier 1 Status (per Series Data)** - According to the contextual data (\`tier\_1\_bankable: false\`), the series does not currently hold BNEF Tier 1 bankable status. This may be a limiting factor in commercial projects financed through non-recourse project finance, where lenders typically require modules from manufacturers with an active BNEF Tier 1 status. - **Monofacial Module – No Bifacial Energy Gain** - The HiTouch 5N series in its monofacial configuration (\`is\_bifacial: false\`) does not generate energy from the module's rear side. The peer comparable Risen RSM144-9-560-585BNDG is available in a bifacial version, enabling an additional yield of 5–25% at ground albedo >20% (e.g., light gravel, snow), which is relevant for ground-mounted commercial installations. - **Product Warranty Starting at 12 Years for Some Variants** - The product warranty period of 12–15 years varies by specific variant. Models at the lower threshold of 12 years fall below the 15-year standard established by premium manufacturers (e.g., REC, Panasonic). When selecting a variant within this series, buyers should verify which option carries the full 15-year product warranty — a material consideration for projects with long financing horizons. ## About this series The Hanersun HiTouch 5N series is an advanced solution based on **N-type TOPCon cell technology**, which redefines efficiency standards in modern photovoltaics. Thanks to the **SMBB (Super Multi-Busbar)** design, these panels offer significantly better current flow and higher resistance to micro-cracks, which directly translates into the longevity of the installation. A key benefit for the investor is the exceptionally **low power degradation rate**, ensuring that the modules maintain high efficiency even after many years of intensive operation in varying weather conditions. This series effectively solves the problem of yield drops on hot days thanks to an optimized temperature coefficient, clearly distinguishing it from traditional older generation modules. HiTouch 5N also features **excellent low-light performance**, generating energy more efficiently on cloudy days as well as during morning and evening hours. It is an ideal choice for both demanding residential prosumers and large commercial farms, where achieving the lowest cost of energy production is key. The robust construction of the modules guarantees **increased mechanical resistance** to extreme snow and wind loads, making them a reliable foundation for any modern solar power plant. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 226.5 W/m² matches the \*\*TOPCon 550-600W\*\* median - At -0.31%/°C, loses 0.02pp more power per degree than \*\*TOPCon 550-600W\*\* median (-0.29%/°C) - At 32.5 kg (1.3 kg above \*\*TOPCon 550-600W\*\* median of 31.2 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 is TOPCon cell technology in Hanersun HiTouch 5N panels and is it worth choosing? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology used in the HiTouch 5N series, delivering cell efficiency up to 24.5%. Compared to mainstream PERC modules, N-type TOPCon cells exhibit near-zero LID (Light-Induced Degradation), meaning the panel retains its rated power output from the very first day of operation and maintains high performance throughout its entire service life. ### Do Hanersun HiTouch 5N panels lose significant power output during hot weather? No — the HiTouch 5N series outperforms standard PERC modules in high-temperature conditions. Its Pmax temperature coefficient is -0.28%/°C, compared to roughly -0.35%/°C for typical PERC panels. At a module temperature of 65°C, which is common during summer in central Europe, the energy yield advantage of HiTouch 5N over older-generation modules can amount to several percentage points. ### What warranty does the Hanersun HiTouch 5N series come with? The HiTouch 5N series includes a 15-year product warranty covering manufacturing defects and material failures, plus a 30-year linear power output warranty. Annual power degradation is guaranteed not to exceed 0.4%, which is better than the industry benchmark for PERC modules and reflects the inherent long-term stability of N-type TOPCon cell technology. ### Does the Hanersun HiTouch 5N produce power on overcast days or in low-light conditions? Yes. N-type TOPCon cells respond better to diffuse irradiance than P-type PERC cells, resulting in higher energy yields during morning and evening hours and on cloudy days. This low-light advantage is particularly relevant in the central European climate, where overcast conditions are common for a significant portion of the year, and where HiTouch 5N measurably outperforms older PERC-based modules. ### Is the 585 W Hanersun HiTouch 5N panel suitable for a residential rooftop installation? The HiTouch 5N 585 W is a large-format module based on the 182 mm cell format, so available roof area and racking load capacity should be verified before purchasing. Its high per-unit power output means fewer panels are required to cover a household's energy demand, which can reduce both BoS costs and installation labor. The series is designed for both residential prosumer systems and large-scale commercial projects. ### How quickly do Hanersun HiTouch 5N panels degrade over years of use? N-type TOPCon cells in the HiTouch 5N nearly eliminate LID, removing the initial power drop seen in P-type cells after first sun exposure. Annual power degradation is guaranteed at no more than 0.4%, meaning the panel should retain over 88% of its nameplate power after 30 years. This compares favorably to standard PERC modules, which typically degrade at 0.45–0.55% per year. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-72HT-565-585-EN-949fa211cb3b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +1.8 pp | | [Hanersun HN18-72H535W](https://comparepv.com/panel/hanersun-hn18-72h535w) | 535 W | -50 W, -1.9 pp, -5 yr warranty | | [Hanersun HN18-72H540W](https://comparepv.com/panel/hanersun-hn18-72h540w) | 540 W | -45 W, -1.8 pp, -5 yr warranty | | [Hanersun HN18-72H545W](https://comparepv.com/panel/hanersun-hn18-72h545w) | 545 W | -40 W, -1.6 pp, -5 yr warranty | | [Hanersun HN18-72H550W](https://comparepv.com/panel/hanersun-hn18-72h550w) | 550 W | Lighter, -1.4 pp, -5 yr warranty | | [Hanersun HN18-72H555W](https://comparepv.com/panel/hanersun-hn18-72h555w) | 555 W | Lighter, -1.2 pp, -5 yr warranty | | [Hanersun HN18-72H560W](https://comparepv.com/panel/hanersun-hn18-72h560w) | 560 W | Lighter, -1.0 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-72ht585w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
