A bifaciality factor of 70–80% is typical for the PERC segment and performs well in ground-mount installations and flat rooftops with high-albedo surfaces. - **SMBB with Round-Wire Conductors (+2% Power Output)** - Super Multi-Busbar technology with round-wire conductors reduces series resistance and improves light scattering across the cell, which — according to manufacturer data — translates to approximately 2% higher module power output compared to conventional flat-ribbon busbars. Round conductors also exhibit greater tolerance to thermomechanical stress, contributing to long-term module durability. - **Half-Cut Cells + 210 mm Format — Enhanced Shade Tolerance** - Splitting cells in half reduces resistive losses and mitigates the impact of partial shading — the module operates as two independent sections, so shading on one half of the panel does not eliminate the output of the entire module. The 210 mm cell format simultaneously delivers high unit power (590–600 Wp) within a standard module footprint. - **30-Year Linear Power Warranty** - The manufacturer provides a 30-year linear power output warranty, exceeding the mid-tier industry standard of 25 years. Combined with a 15-year product warranty, the long-term O&M risk exposure over the asset's lifecycle is significantly reduced for commercial investors. - **High Cell Packing Density (0.5 mm Spacing)** - A cell-to-cell spacing of just 0.5 mm maximizes the module's active area and enhances laminate integrity, directly improving long-term reliability and reducing susceptibility to potential-induced degradation (PID). ## Cons - **Series Discontinued (2023)** - The HN21-60HT series was manufactured from 2021 to 2023 and has been officially discontinued. Availability of new modules, replacement units, and warranty service support is limited to distributor stock; the risk of being unable to source identical modules for system expansion is real. - **PERC Technology — Efficiency Gap vs. TOPCon** - Module efficiency of 20.8–21.2% is notably lower than that of direct N-type TOPCon peers: Tongwei TWMND reaches 23.2%, and Lexron 144 CELL TOPCON achieves 23.23%. The ~2 percentage point gap translates to approximately 9–10% less energy yield from the same roof area, which directly undermines project economics where mounting space is constrained. - **No Tier-1 BNEF Status During the Series' Active Lifecycle** - Hanersun did not achieve a Tier-1 BNEF ranking until Q2 2023 — at the very end of the HN21-60HT series lifecycle. Throughout most of 2021–2022, the manufacturer lacked formal bankability classification, which may have restricted project financing for commercial installations based on these modules and complicated investor due diligence. ## About this series The Hanersun Hitouch 6 (HN21-60HT) series is designed for maximum installation cost-effectiveness, thanks to its large-format cells and solutions that effectively minimize losses within the module. The use of **PERC cells** in combination with **half-cut construction** improves performance under partial shading and reduces the risk of yield losses in less ideal rooftop conditions. A key feature is the **SMBB with round conductors** - this configuration collects current more effectively and helps to utilize light more efficiently, resulting in more stable annual yields. The manufacturer also emphasizes **high-density encapsulation**, which improves cell packing and supports the long-term reliability of the module. The HN21-60HT variant is suitable for both commercial and larger ground-mounted installations, where quick assembly, predictable energy production, and a favorable BOS cost balance are important. The **All Black** option facilitates integration with modern architecture, without compromising on quality. ## Notable figures - Efficiency of 21.2% matches the \*\*PERC 600-650W\*\* median - At 212.0 W/m² power density, roof space requirements are typical for \*\*PERC 600-650W\*\* panels - Temperature coefficient of -0.35%/°C matches the \*\*PERC 600-650W\*\* median - 78% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 65% for efficiency among all PERC panels ## Questions ### Is the Hanersun Hitouch 6 HN21-60HT series still available for purchase? The Hanersun Hitouch 6 (HN21-60HT) series has been discontinued and is no longer actively manufactured. Availability through distributors may be limited to remaining warehouse stock. If you are planning a new installation, it is advisable to consider currently produced Hanersun series or alternative manufacturers offering comparable specifications with full warranty support in place. ### What warranty does the Hanersun Hitouch 6 HN21-60HT come with? The manufacturer provides a 15-year product warranty covering workmanship and materials, along with a 30-year linear power output warranty. This means the module should retain a specified percentage of its rated power over 30 years. Since the series is discontinued, it is worth verifying with your local distributor whether additional after-sales support is available before committing to a purchase. ### What benefits do PERC cells and half-cut construction bring to the Hitouch 6 series? PERC cells feature a passivation layer on the rear side that reflects unabsorbed photons back into the cell, boosting conversion efficiency. The half-cut design splits each cell in two, reducing operating current per cell, which lowers resistive losses and limits the impact of partial shading on the entire module. In practice, the Hitouch 6 performs more reliably on rooftops with chimneys or dormers than conventional full-cell modules. ### Is the Hanersun Hitouch 6 HN21-60HT a bifacial panel, and what does that mean for my installation? Yes, the HN21-60HT is a bifacial module, meaning it harvests energy from both the front and rear surfaces. The additional yield from reflected irradiance (albedo gain) is most beneficial in ground-mount systems over bright surfaces or elevated racking with clearance underneath. On typical pitched residential rooftops the bifacial effect is minimal, so the technology delivers the greatest LCOE advantage in utility-scale and commercial solar farms. ### What is the maximum power output of the Hanersun Hitouch 6 and what type of installations is it suited for? The Hitouch 6 (HN21-60HT) series reaches a maximum power of 600 Wp, placing it in the large-format segment primarily designed for commercial and ground-mount installations. A higher wattage per module reduces the total panel count per MW, lowering overall BoS costs including cabling, racking, and labor. For standard residential rooftop systems, the physical size and weight may be impractical – consult an installer before specifying these modules. ### What makes the SMBB round-wire busbar technology in the Hitouch 6 series different from standard busbars? SMBB (Super Multi Busbar) with round-wire conductors replaces a few wide metal strips with many thin round wires. The circular cross-section reflects light back onto the cell surface more effectively, improving current collection. The higher number of interconnection points also increases resistance to cell microcracks. The result is higher module efficiency and more stable power output over the full service life of the panel. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN21-60HT-590-610-EN-f41adfde52ae.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +4.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +3.4 pp | | [Hanersun HN21-60H590W](https://comparepv.com/panel/hanersun-hn21-60h590w) | 590 W | Lighter, -0.4 pp, -5 yr warranty | | [Hanersun HN21-60H595W](https://comparepv.com/panel/hanersun-hn21-60h595w) | 595 W | Lighter, -5 yr warranty | | [Hanersun HN21-60H605W](https://comparepv.com/panel/hanersun-hn21-60h605w) | 605 W | Cooler, lighter, -5 yr warranty | | [Hanersun HN21-60HT610W](https://comparepv.com/panel/hanersun-hn21-60ht610w) | 610 W | Cooler, heavier, +0.4 pp | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +80 W, lighter, +2.8 pp | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +75 W, lighter, +2.7 pp | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +70 W, cooler, +2.5 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +70 W, lighter, +2.5 pp | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +65 W, cooler, +2.3 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +65 W, lighter, +2.3 pp | --- Source: https://comparepv.com/panel/hanersun-hn21-60ht600w 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.
