The modules are built on **TOPCon technology** paired with large 210 mm silicon wafers, delivering high per-panel output without increasing physical dimensions. The use of **half-cut, multi-busbar cells** reduces resistive losses and improves resistance to microcracks, helping the panel better withstand transport, installation, and long-term mechanical stress. Thanks to its **bifacial design**, the module also captures light reflected from the ground, translating into extra energy yield, particularly in ground-mounted arrays or over light-colored surfaces. The series stands out for **near-zero LID/LeTID degradation** and stable performance under low irradiance, which matters in climates with frequent partial cloud cover, such as Poland's. A reinforced frame ensures resistance to snow and wind loads, and the manufacturer backs the modules with a **30-year power warranty**. The Hitouch 6N works well both for residential prosumer setups and larger commercial projects, where a low cost per watt and predictable long-term durability are key investment factors. ## Notable figures - Efficiency of 21.5% matches the \*\*TOPCon 400-450W\*\* median - 215.2 W/m² power density is 5.0 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - requires larger installation area - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 21.0 kg is typical for \*\*TOPCon 400-450W\*\* panels - #7958 for efficiency, #1309 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Hitouch 6N panel and which installations is it suited for? Hitouch 6N modules reach a maximum power output of up to 720 Wp, making them one of the more powerful panels in their class thanks to large 210 mm silicon wafers. High unit power means fewer panels are needed to reach a target system capacity, making them suitable both for residential rooftop installations with limited space and for commercial projects and utility-scale solar farms, where cost per watt is critical. ### What is TOPCon technology in Hitouch 6N panels and how does it differ from PERC? TOPCon (Tunnel Oxide Passivated Contact) is a cell technology that uses an additional passivation layer to reduce electron recombination and increase conversion efficiency compared to the older PERC technology. In practice, TOPCon panels like the Hitouch 6N generate higher power from the same surface area and perform better at high temperatures and low irradiance, resulting in higher annual energy yield. ### Do the half-cut cells in the Hitouch 6N improve panel durability? Yes, the use of half-cut cells with multiple busbars in the Hitouch 6N reduces resistive losses and increases resistance to microcracks caused during transport, installation, or mechanical loads such as snow or wind. Additionally, in cases of partial shading or single-cell damage, the panel loses less power than a full-cell module, resulting in higher long-term reliability. ### What warranty comes with Hanersun Hitouch 6N panels? Hitouch 6N panels come with a 25-year product warranty and a 30-year power output warranty, guaranteeing a defined performance level over three decades of operation. This is one of the longer warranties on the market, reflecting the manufacturer's confidence in TOPCon technology and panel construction, which matters when calculating the payback period of a solar investment. ### Is Hanersun a tier 1 manufacturer, and does that matter when choosing panels? Hanersun is not currently classified as a tier 1 manufacturer under BloombergNEF's ranking, meaning less bank project financing scale compared to leading brands like Jinko or Trina. This does not automatically mean lower product quality, as Hanersun is a Chinese manufacturer using proven TOPCon technology and offering long warranties. It's still worth checking local warranty service availability in your country before purchasing a larger installation. ### Does the Hitouch 6N perform well under the partly cloudy conditions typical of Poland? Yes, the Hitouch 6N series features near-zero LID and LeTID degradation and stable performance under low irradiance, which matters in climates like Poland with frequent cloud cover and diffuse radiation. TOPCon technology utilizes weak and diffuse light more effectively than older cell technologies, allowing the panel to generate energy efficiently even on overcast days, not only under full sun. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HN21RN-48H-50a70c0c2551.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +2.6 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +2.6 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, heavier, +2.5 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, hotter, +2.5 pp | | [Hanersun HN18RN-54H435W](https://comparepv.com/panel/hanersun-hn18rn-54h435w) | 435 W | +0.3 pp | | [Hanersun HN18RN-54H440W](https://comparepv.com/panel/hanersun-hn18rn-54h440w) | 440 W | +10 W, +0.5 pp | | [Hanersun HN18RN-54H445W](https://comparepv.com/panel/hanersun-hn18rn-54h445w) | 445 W | +15 W, +0.8 pp | | [Hanersun HN18RN-54H450W](https://comparepv.com/panel/hanersun-hn18rn-54h450w) | 450 W | +20 W, +1.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +80 W, cooler, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +65 W, cooler, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +75 W, cooler, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +60 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +70 W, cooler, +3.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +70 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/hanersun-hn21rn-48h430w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
