This solution is especially valued in high-visibility installations — mansard roofs, building facades, and projects with architectural requirements. - **Half-Cut MBB PERC Cell Technology** - Splitting cells in half reduces resistive losses by approximately 2% and limits the impact of partial shading on overall string output. The multi-busbar (MBB) architecture improves resistance to microcracks and enhances current collection under diffuse irradiance conditions. - **Module Efficiency Up to 20.74% — In Line with Peer Comparables** - The top variant in the series achieves 20.74% module efficiency — identical to the EGing STAR SERIES (108-cell, max 405 Wp, 20.74%) and the VSUN405-108BMH-DG (20.74%), placing the series at the upper boundary of the comparable 108-cell PERC segment. - **25-Year Linear Power Output Warranty** - The manufacturer guarantees a linear degradation rate over 25 years — the standard for PERC modules in this class — ensuring predictable energy production throughout the full lifecycle of the installation. ## Cons - **Discontinued Product Line** - Production ceased around 2023. New-stock availability on the market is limited or nonexistent, making it difficult to expand an existing installation with identical modules or to replace failed panels on a like-for-like basis. There is also a risk of limited technical support and reduced manufacturer service availability. - **PERC Technology — Older-Generation Cell Architecture** - P-type PERC cells exhibit a light-induced degradation (LID) rate of 0.5–1% in the first year, whereas competing N-type TOPCon modules (e.g., the Hanersun Hitouch 5N introduced concurrently) achieve less than 0.1%. The power temperature coefficient for PERC is typically -0.35%/°C — worse than N-type (~-0.30%/°C) — resulting in lower energy yield on hot days. - **Product Warranty Limited to 12 Years** - A 12-year product warranty falls below the current industry standard — leading Tier-1 manufacturers (JA Solar, Trina Solar, LONGi) offer 15-year product warranties on comparable PERC modules. This gap is significant when designing systems with bank financing or lease structures. - **No BNEF Tier-1 Bankable Status for This Line** - Hanersun achieved BNEF Tier-1 status only in Q2 2023 — and exclusively for its 600 W+ product lines. The Hitouch 5 series (385–405 Wp, PERC) was not covered by this rating throughout its entire production period (2021–2023), which may restrict financing options for projects requiring modules from bankable manufacturers. ## About this series The Hanersun Hitouch 5 (Full Black) series consists of modules designed with a focus on both high aesthetics and real energy production gains, particularly in locations where the installation is easily visible. The Full Black variant stands out for its cohesive appearance, thanks to its dark finishing elements, which make it easy to match with modern roofs and facades without the "gridded" effect typical of many panels. However, in practice, design is not the only factor. The use of **TOPCon (N-type) cells** or a well-designed half-cut architecture, depending on the series version, translates into better performance in more challenging conditions. The modules are designed to minimize losses and maximize energy yield during periods of lower sunlight, which will be appreciated by users in the Polish climate. The **MBB with half-cut** and **tight cell interconnection** also contribute to stability and reduce the risk of operational problems. In the two-sided versions, the **bifacial technology** provides an additional advantage, ideal for roofs, pergolas, carports, and ground-mounted installations. ## Notable figures - Efficiency of 20.5% matches the \*\*PERC 400-450W\*\* median - Power density of 204.8 W/m² matches the \*\*PERC 400-450W\*\* median - Temperature coefficient of -0.38%/°C is 0.03pp worse than \*\*PERC 400-450W\*\* median (-0.35%/°C) - higher losses in summer heat - Ranked #11468 out of 14005 panels for efficiency in the database ## Questions ### Is the Hanersun Hitouch 5 Full Black series still available for purchase? The Hanersun Hitouch 5 Full Black series has been discontinued and is no longer actively distributed by the manufacturer. Some units may remain in distributor stock, but regular availability should not be expected. Customers interested in Hanersun products should explore the current lineup, such as the TOPCon-based Hitouch 5N series. ### What warranty does Hanersun provide on the Hitouch 5 Full Black panels? The manufacturer offers a 12-year product warranty covering manufacturing defects and materials, plus a 25-year linear power output warranty ensuring the panels perform within rated parameters for a quarter century. Since the series is discontinued, it is strongly recommended to confirm warranty claim procedures in writing with your distributor before completing a purchase. ### What cell technology is used in the Hanersun Hitouch 5 Full Black, and what does it mean for end users? The Hitouch 5 Full Black uses PERC cells combined with a half-cut, MBB (multi-busbar) architecture. This results in lower resistive losses, improved partial-shading tolerance, and better low-irradiance performance. The maximum rated power of this variant is 405 Wp, positioning it as a standard 54-cell residential module. ### Do Hanersun Hitouch 5 Full Black panels perform well under overcast or low-irradiance conditions? Yes, the half-cut and MBB construction reduces losses from partial shading and internal resistance, translating to better output during morning and evening hours and on diffuse-light days typical of Central European climates. Users in cloudy regions can expect more consistent daily generation compared to older single-busbar module designs. ### What sets the Full Black variant apart from a standard Hanersun Hitouch 5 panel? The Full Black variant features an all-black aesthetic: black cells, anodized black frame, and black backsheet that eliminate the grid-like appearance common to panels with white backsheets. This makes it a preferred choice for visible pitched rooftops and modern building facades. The black backsheet may slightly raise operating temperature, but the impact on annual energy yield is negligible. ### Are Hanersun Hitouch 5 Full Black panels bifacial, generating power from both sides? No, the Hitouch 5 Full Black is a monofacial module that generates power from the front side only. Bifacial technology is available in other Hanersun variants such as the Hitouch 5N series. For ground-mounted systems, carports, or pergolas where harvesting reflected irradiance from the rear is beneficial, a bifacial panel would be a better fit. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN18-54HB-385-405-EN-85fd5b937c42.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, +2.6 pp, +5 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (450W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-450w-class) | 450 W | +50 W, cooler, +2.6 pp | | [Q-SUN Solar QNN182-HG450-54](https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg450-54) | 450 W | +50 W, cooler, +2.6 pp | | [Huayao HY440-N108BDD](https://comparepv.com/panel/huayao-hy440-n108bdd) | 450 W | +50 W, cooler, +2.6 pp | | [BYD NLBK-27-450](https://comparepv.com/panel/byd-nlbk-27-450) | 450 W | +50 W, cooler, +2.6 pp | | [Renesola RS41-450NBG-E3](https://comparepv.com/panel/renesola-rs41-450nbg-e3) | 450 W | +50 W, cooler, +2.6 pp | | [Hanersun HN18-54HB385W](https://comparepv.com/panel/hanersun-hn18-54hb385w) | 385 W | -15 W, -0.8 pp | | [Hanersun HN18-54HB390W](https://comparepv.com/panel/hanersun-hn18-54hb390w) | 390 W | -10 W, -0.5 pp | | [Hanersun HN18-54H395W](https://comparepv.com/panel/hanersun-hn18-54h395w) | 395 W | Cooler, -0.3 pp | | [Hanersun HN18-54H405W](https://comparepv.com/panel/hanersun-hn18-54h405w) | 405 W | Cooler, +0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +95 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +105 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +90 W, cooler, +4.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +100 W, cooler, +4.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +100 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/hanersun-hn18-54hb400w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
