It trails only the AE Solar AURORA AE MD-108 by a marginal 0.03 percentage points, a difference that is negligible in practical installation terms. - **Half-cut cell architecture with MBB** - The combination of half-cut technology and multi-busbar (MBB) design reduces series resistance and splits the cell current in two, minimizing resistive losses and improving tolerance to partial shading – a significant advantage on rooftops with dormers, chimneys, or antennas common in Polish single-family residential construction. - **25-year power warranty at ≥89.4%** - The manufacturer guarantees retention of at least 89.4% of nominal power output after 25 years of operation. This figure exceeds the typical industry benchmark for PERC technology (84–87% after 25 years), resulting in better-quantified financial risk when modeling IRR for prosumer installations. - **108-cell format suited to Polish roof dimensions** - The module width of ~1,134 mm and weight of ~21 kg are compatible with standard racking systems (Schletter, K2, Esdec) widely used in Poland. This format simplifies mounting structure selection and reduces BoS costs on typical gable roofs with rafter spacing of 80–100 cm. ## Cons - **Series discontinued as of 2023** - Production ended in 2023 (released 2021, end-of-life 2023). Availability of new modules relies exclusively on distributor inventory stocks. Over a 25-year power warranty horizon, replacing a failed module may be impossible without switching series, creating risks of electrical mismatch and aesthetic inconsistency within the installation. - **PERC technology superseded by TOPCon** - P-type PERC cells are susceptible to light-induced degradation (LID), resulting in 1–3% power loss during initial exposure hours, and degrade at approximately 0.45% per year, whereas N-type TOPCon degrades at ~0.4% annually and is free of LID. Hanersun itself replaced this series with the Hitouch 5N (N-TOPCon, up to 22.8% efficiency). In 2024, TOPCon surpassed 66% of global manufacturing capacity, making PERC a sunset technology. - **12-year product warranty – below industry standard** - Hanersun provides a 12-year product warranty, while JA Solar, LONGi Solar, and Trina Solar offer 15-year product warranties in the equivalent segment. For installations operated under a net-billing model, this means three fewer years of coverage during the financially critical period of system payback. - **No Tier-1 bankable status for this series** - Hanersun attained BNEF Tier 1 classification in May 2023 exclusively for its 600 W+ product lines; the HN18-54H series is not covered by that ranking. For installations financed through green loans or leasing, some financial institutions require Tier-1 modules, which may disqualify this series from eligible financing or result in higher insurance premiums. ## About this series The Hanersun Hitouch 5 (HN18-54H) series consists of compact, monofacial modules based on PERC monocell technology, designed for high energy production without complicating the installation project. The use of **half-cut** construction and a **multi-busbar architecture** effectively reduces resistive losses and improves performance under partial shading - which is important on roofs with dormers, chimneys, or extensive ventilation systems. A key feature of this series is the **high-density interconnection of cells** with minimal spacing, which supports the stability of parameters and the aesthetic appearance of the module layout. Thanks to its adaptable format, the Hitouch 5 (HN18-54H) is well-suited for single-family homes, small businesses, and the modernization of existing installations. An additional advantage is **lower risk of hot spots**, which translates into greater reliability over the long term and more predictable yields in Polish conditions. ## Notable figures - Efficiency of 20.2% is 0.8pp above the \*\*PERC 0-400W\*\* median (19.4%) - At 202.3 W/m² power density, this panel generates 7.9 W/m² more per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - At -0.35%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - At 21.5 kg, weight matches the \*\*PERC 0-400W\*\* median - Ranked #11930 out of 14005 panels for efficiency in the database ## Questions ### Is the Hanersun Hitouch 5 (HN18-54H) series still available for purchase? The Hitouch 5 (HN18-54H) series has been discontinued and is no longer offered as a new product by distributors. Hanersun replaced it with the newer Hitouch 5N line featuring higher-efficiency cells. If you are looking for a similar PERC-based solution, check with your distributor for remaining stock or consider the current successor series. ### What is the rated power of the Hanersun Hitouch 5 HN18-54H and is it enough for a typical home? The module's peak power output is 415 Wp. For an average single-family home consuming 3,500–5,000 kWh per year, you typically need 8–14 panels, resulting in a system size of 3.3–5.8 kWp. The compact format of the series makes it easy to fit standard pitched roofs without requiring custom racking solutions. ### What is half-cut and MBB technology in the Hitouch 5 panel and why does it matter? Half-cut means each PERC cell is laser-split in two, reducing the current per half-cell and lowering resistive losses by several percentage points. MBB (multi-busbar) replaces a few wide busbars with many thin wires, shortening the electron path across the cell. Together they improve energy yield under partial shading conditions and significantly reduce the risk of hot spots forming over the module's lifetime. ### Will the Hanersun Hitouch 5 HN18-54H perform well on a roof with chimneys and dormers? Yes, this is one of the key strengths of the series. The half-cut cell layout ensures that shading one portion of the module does not shut down the entire string, only a segment of it. Energy losses from transient shadows cast by chimneys, dormers, or antennas are therefore noticeably lower than with standard full-cell modules. As a monofacial panel, it also requires no reflective surface underneath, simplifying system design. ### What warranty does the Hanersun Hitouch 5 HN18-54H come with and what does it cover? Hanersun offered a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. This means the module should retain at least the minimum power percentage specified in the datasheet after 25 years of operation. Since the product has been discontinued, keep all purchase documentation, as warranty claims must be processed through authorized distributors. ### Is Hanersun a reputable manufacturer and can it be trusted for a panel purchase? Hanersun is a Chinese PV module manufacturer not currently listed among Tier 1 suppliers by major rating agencies such as BloombergNEF. This means that bank-financed or utility-scale projects may require additional due diligence. For residential and small commercial installations without third-party financing, Hanersun modules offered solid value for money, and the 25-year power warranty was in line with market standards. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-54H-395-415-EN-8d4ae8200eec.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +2.9 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.8 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +2.6 pp | | [Hanersun HN18-54HB385W](https://comparepv.com/panel/hanersun-hn18-54hb385w) | 385 W | -10 W, hotter, -0.5 pp | | [Hanersun HN18-54HB390W](https://comparepv.com/panel/hanersun-hn18-54hb390w) | 390 W | Hotter, -0.2 pp | | [Hanersun HN18-54HB400W](https://comparepv.com/panel/hanersun-hn18-54hb400w) | 400 W | Hotter, +0.3 pp | | [Hanersun HN18-54H405W](https://comparepv.com/panel/hanersun-hn18-54h405w) | 405 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +95 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-54h395w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
