For a 2021-era PERC module, this represents a top-tier configuration that translates into more stable linear degradation over the module's service life. - **20.8–21.2% Efficiency – Top of PERC Class (2021)** - At the time of its 2021 launch, these values positioned the Hitouch 6 among the leading monofacial PERC modules in the 600 W+ format. Among peer comparables, only the Talesun BISTAR (21.5%) achieves a similar efficiency level within PERC technology. - **25-Year Linear Power Warranty** - The manufacturer provides a 25-year energy production warranty, meeting the minimum bankability requirement for utility-scale PV projects and C&I installations financed through debt or lease agreements. ## Cons - **Discontinued Production – Limited Availability** - The series was discontinued in 2023. Replacing damaged modules or expanding an existing installation will be increasingly difficult; serviceability and the availability of spare parts (frames, seals) present growing risks as time passes. - **PERC vs. N-Type TOPCon Peers – ~2 pp Efficiency Gap** - The 20.8–21.2% efficiency is significantly lower than the Tongwei TWMND N-type (23.2%) and Lexron TOPCon (23.23%). For the same system output, a proportionally higher module count or greater roof area is required, resulting in higher BoS and racking costs per kWp. - **Monofacial Module – No Bifacial Energy Gain** - Unlike the bifacial peer comparable Tongwei TWMND, the HN21-60H series does not harvest energy from the rear side. On ground-mounted installations with high-albedo surfaces, bifacial modules typically generate 5–15% higher annual energy yield at the same nameplate power rating. - **12-Year Product Warranty – Below Current Standard** - The product warranty stands at 12 years, while leading manufacturers currently set a higher benchmark (LONGi: 25 years, JinkoSolar: 15 years, JA Solar: 12–15 years). This shortens the period of full workmanship protection over a 25-year project horizon. ## About this series The Hanersun HN21-60H (Hitouch 6) 590-610W series are large-format modules designed to maximize energy production from every square meter of the structure. The use of monocrystalline cells in a **half-cut** configuration and an **SMBB (multi-busbar)** architecture improves current collection and reduces losses due to microcracks, resulting in more stable performance over time. Thanks to the **high cell density**, the cells are connected with minimal spacing, which maximizes the effective use of the module's surface area without artificially inflating its parameters. This is a good choice when real cost savings are a priority - fewer modules, fewer mounting components, and shorter installation times for the same system power. The series is suitable for PV farms, large industrial rooftops, and C&I projects where **resistance to degradation** and predictable production under Polish climate conditions are important. It stands out from the competition due to its combination of large format with a refined connection technology, which supports long-term reliability. ## Notable figures - Efficiency of 20.8% matches the \*\*PERC 550-600W\*\* median - At 208.5 W/m², this panel generates 4.4 W/m² less per unit area than \*\*PERC 550-600W\*\* median (212.9 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 550-600W\*\* median - In the top 75% for efficiency among all PERC panels ## Questions ### Is the Hanersun HN21-60H (Hitouch 6) 590-610W series still available for purchase? The Hanersun HN21-60H (Hitouch 6) 590-610W series has been discontinued and is no longer actively offered by the manufacturer. Some distributors may still carry limited stock, but availability is not guaranteed and full power-bin selection cannot be assumed. If you need a comparable Hanersun product, the newer Hitouch 6N series with TOPCon cells offers higher power output and module efficiency. ### What warranty does Hanersun provide on the Hitouch 6 HN21-60H panels? Hanersun provides a 12-year product warranty covering manufacturing defects and physical integrity, along with a 25-year linear power warranty. After 25 years, the module should retain at least 84.8% of its rated power output. This is a standard warranty scope for commercial-grade PV modules, broadly comparable with other established manufacturers in the segment. ### What type of installations are the Hanersun HN21-60H 600W panels best suited for — will they work on a large industrial rooftop? Yes. The large module format (2172 x 1303 mm) and up to 610 W peak power make the HN21-60H series well-suited for commercial C&I installations, utility-scale solar farms, and large industrial rooftops. Fewer modules are required to reach the same system capacity, which directly reduces BoS costs — mounting hardware, cabling, and installation labor. ### What do SMBB and half-cut cell technology mean in the Hanersun HN21-60H, and does it make a real practical difference? SMBB (multi-busbar) uses multiple thin round-wire conductors to collect current from each cell, reducing resistive losses and improving resilience to microcracks. Half-cut splits each PERC cell in two, so that partial shading only affects one half of the module string while the other continues generating at full capacity. Together, these technologies contribute to lower annual degradation rates and more stable long-term energy output. ### What is the actual efficiency of the Hanersun HN21-60H 610W panel and how does it compare to current market offerings? The 610W variant achieves a module efficiency of 21.6%, enabled by 210mm PERC monocrystalline cells with high-density encapsulation and 0.5mm cell spacing. At the time of its release, this placed the series at the upper end of the PERC market. It is worth noting that current TOPCon and HJT technologies now routinely exceed 22-23% efficiency, which is relevant when comparing against today's available modules. ### Do Hanersun HN21-60H panels perform well in the Polish climate — under overcast conditions and low winter temperatures? Yes. The half-cut PERC cell design improves performance under diffuse irradiance typical of Central European weather. The negative temperature coefficient (approx. -0.35%/°C for PERC) means the module produces more power on cooler days compared to its STC rating. The module is also rated for a snow load of 5400 Pa and wind load of 2400 Pa, meeting structural requirements for Polish climatic zones in commercial installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN21-60H-590-610-EN-8bf2199ff29d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +4.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, cooler, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, +3.8 pp, +5 yr warranty | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +3.6 pp | | [Hanersun HN21-60H595W](https://comparepv.com/panel/hanersun-hn21-60h595w) | 595 W | Very close match | | [Hanersun HN21-60H600W](https://comparepv.com/panel/hanersun-hn21-60h600w) | 600 W | +10 W, +0.4 pp | | [Hanersun HN21-60H605W](https://comparepv.com/panel/hanersun-hn21-60h605w) | 605 W | +15 W, cooler, +0.6 pp | | [Hanersun HN21-60HT610W](https://comparepv.com/panel/hanersun-hn21-60ht610w) | 610 W | Heavier, +0.8 pp, +5 yr warranty | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | +90 W, +3.2 pp, +5 yr warranty | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | +85 W, +3.1 pp, +5 yr warranty | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +80 W, cooler, +2.9 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | +80 W, +2.9 pp, +5 yr warranty | | [Q-SUN Solar QN-665HJT-01](https://comparepv.com/panel/q-sun-solar-qn-665hjt-01) | 665 W | +75 W, cooler, +2.7 pp | | [Gamko New Energy GKA210N120-665](https://comparepv.com/panel/gamko-new-energy-gka210n120-665) | 665 W | +75 W, +2.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/hanersun-hn21-60h590w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
