The 182 mm format ensures broad compatibility with widely deployed racking systems (Schletter, K2, Esdec), simplifying project logistics. - **Round Wire Busbars (RWB)** - The circular cross-section of round wire busbars widens the effective light-acceptance angle and reduces optical shading on the cell surface compared to flat ribbons, improving yield at low solar angles — a meaningful advantage for installations at latitudes typical of Poland (approx. 50–55°N). - **25-Year Linear Power Warranty** - The manufacturer guarantees ≥84.8% retention of nominal power output after 25 years, with a linear degradation rate of ~0.55%/year (years 2–25), in line with market standards for the PERC segment. The product warranty covers 12 years. - **High-Density Cell Encapsulation** - Minimized inter-cell gaps increase the module's active working area and reduce reflective losses between cells, translating to higher specific yield per unit of module area compared to older designs with wider cell spacing. ## Cons - **Series Discontinued (since 2023)** - Production ended after approximately two years of market availability (2021–2023). The discontinuation of this PERC line means limited availability of replacement modules, a risk of electrical parameter mismatch when replacing individual units, and potential serviceability challenges over the long operational horizon (25-year power warranty). - **20.71% Efficiency — Meaningfully Below Peers** - At the same power class (535 W), the Renesola RS5-535NBG-E2 and Heliene 132HC M10 achieve 22.53% efficiency — a difference of ~1.82 percentage points. This means the Hanersun module requires approximately 2.58 m² versus ~2.38 m² for competing products at identical rated power, which is a real constraint on rooftops with limited usable area. - **PERC Superseded by TOPCon Within Hanersun's Own Portfolio** - Hanersun has replaced this series with the Hitouch 5N modules (N-type TOPCon, up to 23.2% efficiency, temperature coefficient Pmax approx. -0.29%/°C vs. -0.35%/°C for this PERC series). Opting for the older technology means higher performance losses on hot days and lower annual energy yield at the same nominal power rating. ## About this series The Hanersun Hitouch 5 HN18-72H (535-555W) series has been designed to maximize energy yield while maintaining high compatibility with popular mounting solutions and installation designs. The use of PERC monocrystalline cells in a 182 mm format, along with the **half-cut** configuration, allows for reduced losses and improved performance in partially shaded conditions, which is particularly important on roofs with complex geometries. Thanks to the **MBB technology**, the module more effectively collects current from the cell surface, while the **high-density encapsulation** with minimal spacing between cells results in a larger active surface area. A key feature of the series is also the **round cable assemblies**, which improve light utilization and provide more stable operation in variable sunlight conditions. The Hitouch 5 HN18-72H is suitable for commercial and industrial installations, as well as for larger rooftop and ground-mounted systems, where predictability, resistance to hotspots, and easier logistics are important compared to modules with even larger formats. ## Notable figures - Efficiency of 20.7% matches the \*\*PERC 500-550W\*\* median - At 207.1 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 500-550W\*\* median - Ranked #10721 out of 14005 panels for efficiency in the database ## Questions ### Is the Hanersun Hitouch 5 HN18-72H series still available for purchase? The Hitouch 5 HN18-72H series has been discontinued and is no longer in regular production. If you need modules with similar specs — monocrystalline PERC, 182 mm cell format, 535–555 W output range — it's worth checking with your distributor for remaining stock or considering a current Hanersun series with comparable performance. ### What warranty does the Hanersun Hitouch 5 HN18-72H come with? The Hitouch 5 HN18-72H carries a 12-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. After 25 years of operation the module should retain at least 80–82% of its initial rated power. Always verify the exact degradation schedule in the current warranty document from an authorized distributor. ### How does the Hanersun Hitouch 5 HN18-72H handle partial roof shading? The half-cut cell layout splits each module into two independent electrical halves, so shading on one section does not shut down the entire panel. Combined with the PERC cell technology and 182 mm format, this significantly reduces energy losses on rooftops with chimneys, dormers, or other obstructions that cast shadows at different times of day. ### What are the round busbars in the Hitouch 5 panels and do they actually improve performance? Round busbars are a feature of the MBB technology used in this series. Their circular cross-section reflects and scatters low-angle light back onto the cell surface, improving energy yield during morning and afternoon hours and under diffuse irradiance. They also reduce micro-crack propagation risk compared to flat busbars, contributing positively to long-term module reliability. ### Is the Hanersun Hitouch 5 HN18-72H suitable for large commercial and industrial installations? Yes. With a power range of 535–555 W and a 182 mm PERC cell format, the Hitouch 5 HN18-72H is designed primarily for commercial rooftop and ground-mounted systems. Its dimensions offer better on-site logistics than ultra-large 600+ W formats while still delivering high power density per square meter, simplifying both system design and installation. ### Are the Hanersun Hitouch 5 HN18-72H panels bifacial? No. The Hitouch 5 HN18-72H is a monofacial module — it captures light from the front side only and does not harvest radiation reflected from the ground. If your site features a high-albedo surface such as gravel, concrete, or snow and provides sufficient mounting clearance, consider a bifacial series with similar wattage to maximize annual energy yield. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-72H-535-555-EN-61e21a336f39.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +4.1 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [Hanersun HN18-72H540W](https://comparepv.com/panel/hanersun-hn18-72h540w) | 540 W | Very close match | | [Hanersun HN18-72H545W](https://comparepv.com/panel/hanersun-hn18-72h545w) | 545 W | +10 W, +0.4 pp | | [Hanersun HN18-72H550W](https://comparepv.com/panel/hanersun-hn18-72h550w) | 550 W | +15 W, +0.6 pp | | [Hanersun HN18-72H555W](https://comparepv.com/panel/hanersun-hn18-72h555w) | 555 W | +20 W, +0.8 pp | | [Hanersun HN18-72H560W](https://comparepv.com/panel/hanersun-hn18-72h560w) | 560 W | +25 W, +1.0 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +100 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-72h535w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
