According to manufacturer data, this translates to 5–25% additional energy output compared to monofacial modules, making the series cost-effective for carports, pergolas, and installations over high-albedo sub-surfaces. - **Half-Cut + MBB – Lower Losses and Reduced Hot-Spot Risk** - Half-cut cells combined with multi-busbar (MBB) technology reduce resistive losses and minimize the risk of hot-spot formation. The manufacturer confirms improved partial-shading tolerance and a lower probability of mechanical damage during transport and installation. - **30-Year Linear Power Warranty** - The manufacturer guarantees an average annual power degradation of no more than 0.4% in years 2–30, which outperforms the standard 25-year warranties offered by some peer comparables (e.g., VDS Renewable). The extended warranty horizon supports financial models for both residential prosumer and commercial installations. - **Solid Efficiency for a 2021-Generation Bifacial PERC Module** - An efficiency range of 20.23–20.99% was a competitive result for 182 mm PERC modules at the time of launch (2021). By comparison, peer comparable VDS-S144/FNH reaches a maximum of 20.4%, meaning the top-tier HN18-54HT variant leads that series by approximately 0.6 percentage points. ## Cons - **Discontinued Production – Limited Availability** - The series was discontinued in 2023. Availability of new modules is severely restricted, and warranty service as well as potential like-for-like replacements may prove difficult over the declared 30-year power warranty horizon. - **Product Warranty of Only 15 Years** - The industry standard is a 25-year product warranty (e.g., Luxor Solar in the same power class offers 25 years). The manufacturer's materials-and-workmanship warranty reduced to 15 years represents a real risk of module replacement costs arising between years 15 and 25 of system operation. - **PERC Technology, Not N-Type TOPCon** - The HN18-54HT series is based on P-type PERC cells, not N-type TOPCon as incorrectly implied by some marketing materials — the TOPCon variant is the separate HN18N-54HT series. PERC cells exhibit higher light-induced degradation (LID) and inferior high-temperature performance compared to N-type, and the maximum efficiency of 20.99% is lower than TOPCon-based peer comparables: Sunket at 21% and Luxor at 21.33%. - **No Bankable Status During the Series' Sales Period** - According to manufacturer data, the Hitouch 5 series (395–410 Wp, PERC) operated outside the BNEF Tier 1 bankable list — Hanersun achieved Tier 1 BNEF status only in Q2 2023, and exclusively for 600 W+ modules. For project finance and installation insurance, this may result in heightened due diligence requirements or outright financing rejection. ## About this series The Hanersun Hitouch 5 (HN18-54HT) series is designed to maximize energy yield from the same roof area, without increasing operational risks. The use of N-type cells in the TOPCon technology results in **excellent performance in low-light conditions** and **minimal susceptibility to LID and LeTID degradation**, which, in practice, makes it easier to maintain high energy production for years. The **half-cut design with multiple current rails (MBB)** reduces losses and improves resistance to microcracks, while the dense cell packing supports stable performance in everyday conditions. The bidirectional version allows for the sensible use of reflected light, making the panels suitable not only for residential rooftops but also for carports, pergolas, and commercial installations, where additional yield is important. If you are looking for a module that genuinely combines **high efficiency in outdoor conditions** with predictability and durability, the Hitouch 5 (HN18-54HT) stands out from many standard PERC panels. ## Notable figures - Efficiency of 20.7% matches the \*\*PERC 400-450W\*\* median - At 207.4 W/m² power density, roof space requirements are typical for \*\*PERC 400-450W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - At 24.5 kg, this panel is 2.5 kg heavier than the \*\*PERC 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 78% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### Is the Hanersun Hitouch 5 (HN18-54HT) series still available for purchase? The Hitouch 5 (HN18-54HT) series has been discontinued and is no longer manufactured by Hanersun. It may still be available from select distributors as remaining stock. Before purchasing, verify that the seller can supply full technical documentation and will honor the manufacturer's 15-year product warranty and 30-year power output warranty. ### What warranty does the Hanersun Hitouch 5 HN18-54HT come with? Hanersun provides a 15-year product warranty and a 30-year linear power output warranty for the Hitouch 5 (HN18-54HT) series. The 30-year power guarantee means the manufacturer commits to maintaining specified output parameters for three decades — a benchmark required by most installers and project finance lenders. ### What does bifacial technology offer in the Hitouch 5, and when does a bifacial installation make sense? The bifacial Hitouch 5 (HN18-54HT) generates electricity from both the front and rear surfaces by harvesting light reflected from the ground or surrounding surfaces. The greatest bifacial gain occurs on light-colored substrates — gravel, concrete, or white roofing membrane — and on elevated mounting structures such as carports, pergolas, and ground-mount systems. On a standard dark sloped roof, bifacial gain is marginal and rarely exceeds a few percent. ### What is the peak power of the Hanersun Hitouch 5 HN18-54HT, and how many panels do I need for a 5 kWp system? The Hitouch 5 (HN18-54HT) module has a maximum power of 410 Wp under STC conditions. For a 5 kWp system you need approximately 12–13 panels: 12 × 410 W = 4.92 kWp, 13 × 410 W = 5.33 kWp. The exact count depends on available roof area, roof orientation, and the MPPT input range of the selected inverter. ### How does the Hanersun Hitouch 5 HN18-54HT differ from standard PERC panels without half-cut technology? The Hitouch 5 combines PERC cells with a half-cut, multi-busbar (MBB) design. Splitting each cell in half reduces resistive losses and improves partial-shading tolerance, while multiple busbars shorten current paths and lower the risk of output degradation from micro-cracks. In practice, this results in more stable energy production under everyday conditions, especially on overcast days. ### Is Hanersun a Tier 1 manufacturer, and how does that affect buying the Hitouch 5? Hanersun is not classified as a Tier 1 manufacturer according to industry rankings such as BloombergNEF. This means the company does not self-finance utility-scale projects on public capital markets, which may complicate bank financing for larger commercial installations. For residential buyers, the most critical factors are the written warranty terms in the product documentation and the availability of an authorized service partner throughout the full warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-54HT-395-415-EN-19d16276f2d0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +50 W, cooler, +2.6 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +50 W, cooler, +2.6 pp | | [Yingli YL455CF54 e/2](https://comparepv.com/panel/yingli-yl455cf54-e-2) | 455 W | +50 W, cooler, +2.6 pp | | [Einnova Solarline ESM-455T](https://comparepv.com/panel/einnova-solarline-esm-455t) | 455 W | +50 W, cooler, +2.6 pp | | [SunEvo Solar SE5-54HBC-455W](https://comparepv.com/panel/sunevo-solar-se5-54hbc-455w) | 455 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (455W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-455w-class) | 455 W | +50 W, cooler, +2.6 pp | | [Luxor Solar LX-455M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-455m-182r-96-gg) | 455 W | +50 W, cooler, +2.6 pp | | [Hanersun HN18-54HB385W](https://comparepv.com/panel/hanersun-hn18-54hb385w) | 385 W | Hotter, -1.0 pp, -5 yr warranty | | [Hanersun HN18-54HB390W](https://comparepv.com/panel/hanersun-hn18-54hb390w) | 390 W | Hotter, -0.8 pp, -5 yr warranty | | [Hanersun HN18-54H395W](https://comparepv.com/panel/hanersun-hn18-54h395w) | 395 W | Lighter, -0.5 pp, -5 yr warranty | | [Hanersun HN18-54HB400W](https://comparepv.com/panel/hanersun-hn18-54hb400w) | 400 W | Hotter, lighter, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +105 W, cooler, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +90 W, cooler, +4.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +85 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +95 W, cooler, +3.8 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-54ht405w 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.
