The use of 182 mm half-cells allows for a significant reduction in energy losses and minimizes the risk of hot-spots, translating into higher operational stability for the entire system. These modules are characterized by an exceptionally **low temperature coefficient**, making them an ideal choice for Polish climatic conditions, where variable sunlight and high summer temperatures often reduce yields. Thanks to the anti-reflective coating and high resistance to potential-induced degradation, investors gain confidence in long-term profitability. This series solves the problem of limited mounting space, offering **maximum power density** per square meter, which is crucial for single-family homeowners and small businesses. Compared to the competition, Q-SUN Solar QNM182-HS-60 stands out with its **excellent low-light performance**, generating energy efficiently even on cloudy days or during morning and evening hours. It is a solid foundation for a modern micro-installation, combining technical innovation with uncompromising mechanical durability for years. ## Notable figures - At 21.2% efficiency, this panel is on par with typical \*\*PERC 450-500W\*\* modules - 212.4 W/m² power density - 3.9 W/m² more than \*\*PERC 450-500W\*\* median (208.5 W/m²), more power per roof area - -0.37%/°C temperature coefficient - 0.02pp worse than \*\*PERC 450-500W\*\* median (-0.35%/°C), expect higher hot weather losses - #9076 for efficiency, #13081 for temperature performance out of 14005 panels ## Questions ### Is the Q-SUN Solar QNM182-HS-60 series still available for purchase? The QNM182-HS-60 series has been discontinued by Q-SUN Solar and is no longer manufactured. Some distributors may still carry warehouse stock, but availability is limited. Before ordering, confirm stock levels with your dealer and clarify who handles warranty claims — the regional importer or Q-SUN Solar directly. For new installations, we recommend considering currently produced series with comparable or improved specifications. ### What warranty does the Q-SUN Solar QNM182-HS-60 carry? Q-SUN Solar provides a 12-year product warranty covering material defects and workmanship, alongside a 25-year linear power output warranty. The power warranty guarantees the module retains a specified percentage of its rated output over 25 years. Since this series is discontinued, verify with your distributor whether warranty claims are processed by the local importer or directly by Q-SUN Solar before committing to a purchase. ### What cell technology does the QNM182-HS-60 use and what does it mean for system performance? The QNM182-HS-60 series uses PERC (Passivated Emitter and Rear Cell) technology with 182 mm half-cut cells. Rear surface passivation reduces charge carrier recombination, yielding higher efficiency than standard monocrystalline cells. The half-cut design lowers operating current, which minimizes resistive losses, reduces hot-spot risk, and improves performance under partial shading conditions such as chimneys or roof dormers. ### How do QNM182-HS-60 panels perform during winter and on overcast days in Poland? The QNM182-HS-60 series handles Poland's variable climate well. The 182 mm half-cut PERC cells respond effectively to diffuse light common on overcast Central European days. A low temperature coefficient limits power loss during hot summers, while the robust aluminum frame withstands the snow loads and wind pressure typical in Poland throughout the 25-year power warranty period. ### How much energy will a 10-panel Q-SUN Solar QNM182-HS-60 460W system produce per year? Ten QNM182-HS-60 panels at 460 Wp each total 4.6 kWp. Under Polish irradiance conditions (approximately 950–1,050 kWh/kWp per year), such a system will generate an estimated 4,370–4,830 kWh annually — enough to cover the consumption of a typical Polish household. Actual yield depends on roof orientation, tilt angle, shading, and local irradiance data. ### Are Q-SUN Solar QNM182-HS-60 panels bifacial or monofacial? The QNM182-HS-60 series is monofacial — power is generated from the front side only. These modules do not feature bifacial technology, so they do not harvest additional energy from light reflected off the ground or rooftop surface. For standard pitched-roof residential installations, monofacial modules are fully adequate and the absence of a rear active layer has no negative impact on system economics. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNM182-HS440-460-60-35mm-oversea-location-compressed-3-1-fc324253656e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +3.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.5 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.3 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +3.3 pp, +5 yr warranty | | [Q-SUN Solar QNM182-HS440-60](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs440-60) | 440 W | -20 W, -0.9 pp | | [Q-SUN Solar QNM182-HS445-60](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs445-60) | 445 W | -15 W, -0.7 pp | | [Q-SUN Solar QNM182-HS450-60](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs450-60) | 450 W | -10 W, -0.5 pp | | [Q-SUN Solar QNM182-HS455-60](https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs455-60) | 455 W | Very close match | | [Q-SUN Solar QN-465HT-06](https://comparepv.com/panel/q-sun-solar-qn-465ht-06) | 465 W | Cooler, heavier, +5 yr warranty | | [Q-SUN Solar QN-470HT-06](https://comparepv.com/panel/q-sun-solar-qn-470ht-06) | 470 W | Cooler, +0.5 pp, +5 yr warranty | | [Q-SUN Solar QN-475HT-06](https://comparepv.com/panel/q-sun-solar-qn-475ht-06) | 475 W | Cooler, +0.8 pp, +5 yr warranty | | [Q-SUN Solar QN-480HT-06](https://comparepv.com/panel/q-sun-solar-qn-480ht-06) | 480 W | Cooler, +1.0 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +100 W, cooler, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +95 W, cooler, +3.4 pp | --- Source: https://comparepv.com/panel/q-solar-limited-qnsolar-qnm182-hs460-60 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
