The series matches the competition on the parameter that matters most to system designers. - **Half-cut cells + MBB + high-density encapsulation** - The combination of half-cut cells (reducing resistive losses by ~50% versus full cells), multi-busbar technology, and minimized inter-cell spacing lowers the risk of hot spots and improves yield under partial shading — identified in the manufacturer's datasheet as a core design objective of the series. - **25-year linear power warranty, degradation ≤0.4%/year** - The manufacturer guarantees >84.8% of nominal power output after 25 years, with annual degradation not exceeding 0.4%. This is the standard specification for the medium-premium PERC segment and is consistent with what peer-comparable modules in the same power class offer. - **High mechanical durability** - The module is certified for snow loads of 5,400 Pa and wind loads of 2,400 Pa, allowing deployment in demanding climatic conditions without requiring additional reinforcement of the mounting structure. - **M10 format (182 mm) — broad installation compatibility** - The standard 182 mm cell format ensures full compatibility with the majority of widely used racking systems and inverters available on the European market, simplifying logistics and module replacement. ## Cons - **Discontinued series — limited availability** - Production of the Hitouch 5 series (HN18-72H) ended in 2023. New modules are available only from existing warehouse stock; over the 25-year power warranty horizon, this increases the risk of inadequate service support and the inability to source identical modules when expanding an installation. - **Monofacial only — no rear-side energy gain** - Two of the three direct peers — the DAH Solar DHM-T72X10/BF/FS and the Premier Energies 144 HC PERC Bifacial — offer a bifacial variant with a potential additional yield of 5–25% depending on ground albedo. On installations with high-albedo surfaces (gravel, concrete, snow), this series surrenders a measurable productivity advantage. - **PERC technology — superseded by TOPCon** - Hanersun launched the Hitouch 5N series (TOPCon) as early as 2022, with a maximum efficiency of 23.2% and a lower LID degradation rate. At a comparable price point, selecting new TOPCon modules is technically justified by higher annual energy yield and longer cell lifetime. ## About this series The Hanersun Hitouch 5 (HN18-72H) series is designed for installations where high energy production is a priority, while maintaining practical compatibility with popular mounting systems and logistics. The modules utilize MONO PERC cells in combination with a **half-cut** design and **MBB technology**, which helps to minimize losses and improve performance under partial shading. A key feature is the **high-density encapsulation** with minimal spacing between cells - this results in better use of the active surface area and more stable operation in real-world conditions. The HN18-72H variant is suitable for both residential installations on pitched and flat roofs, as well as larger commercial projects where repeatability of parameters and reliability are important. An additional advantage is the **reduced risk of hot spots** and solutions that increase yield from the same surface area, which makes project optimization easier without the need to "over-engineer" the installation. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 212.9 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 550-600W\*\* median - Weight of 28.5 kg (2.3 kg below \*\*PERC 550-600W\*\* median of 30.8 kg) allows easier transport and roof mounting - In the top 62% for efficiency among all PERC panels ## Questions ### Is the Hanersun Hitouch 5 HN18-72H series still available for purchase? The Hanersun Hitouch 5 (HN18-72H) series has been discontinued. New units may still be available in limited quantities through distributors with remaining inventory. For new installations, Hanersun offers the successor Hitouch 5N (HN18N-72H) series based on TOPCon cell technology, which delivers higher efficiency and greater power output. ### What warranty comes with the Hanersun Hitouch 5 HN18-72H panels? Hanersun provides a 12-year product warranty and a 25-year linear power warranty on the Hitouch 5 HN18-72H modules. After 25 years of operation, the panel is guaranteed to retain at least 84.8% of its rated output power. These terms are standard for MONO PERC modules in this class and provide solid long-term investment protection. ### What is the maximum power output and efficiency of the Hanersun HN18-72H? The HN18-72H variant achieves a peak output of 560 Wp with a module efficiency of up to 21.7%. These figures result from 144 half-cut 182 mm MONO PERC cells combined with MBB (multi-busbar) technology and high-density cell encapsulation with minimal cell gaps. The module measures 2278 × 1134 × 30 mm and weighs 28.5 kg. ### How does the Hanersun Hitouch 5 HN18-72H handle partial shading? The half-cut cell design splits each cell into two independently operating halves, limiting the impact of shadows from chimneys, dormers, or antennas. This is reinforced by the MBB architecture, which shortens current paths and reduces the risk of hot spots. In practice, this translates to improved annual energy yield on rooftops subject to irregular shading. ### Is the Hanersun HN18-72H module suitable for pitched and flat roofs? Yes, the Hitouch 5 HN18-72H is compatible with standard racking systems used on both pitched and flat roofs. The module is certified to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa, meeting the requirements of most residential and commercial installations in Central Europe. Given its weight of 28.5 kg and dimensions of 2278 × 1134 mm, a properly rated mounting structure is required. ### How does the Hanersun Hitouch 5 HN18-72H compare to the Hitouch 5N series? The Hitouch 5N (HN18N-72H) is the next-generation series featuring TOPCon cells instead of PERC, offering efficiency up to 23.2% and power output up to 600 Wp. The Hitouch 5 (HN18-72H) relies on proven MONO PERC half-cut technology with MBB, reaching up to 560 Wp. Since the Hitouch 5 has been discontinued, the 5N series is the recommended choice for new installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-72H-540-560-EN-fd3c8cda18c9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [Hanersun HN18-72H535W](https://comparepv.com/panel/hanersun-hn18-72h535w) | 535 W | -15 W, -0.6 pp | | [Hanersun HN18-72H540W](https://comparepv.com/panel/hanersun-hn18-72h540w) | 540 W | -10 W, -0.4 pp | | [Hanersun HN18-72H545W](https://comparepv.com/panel/hanersun-hn18-72h545w) | 545 W | Very close match | | [Hanersun HN18-72H555W](https://comparepv.com/panel/hanersun-hn18-72h555w) | 555 W | Very close match | | [Hanersun HN18-72H560W](https://comparepv.com/panel/hanersun-hn18-72h560w) | 560 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-72h550w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
