This may limit bank financing availability for larger commercial installations. - **12-year product warranty** - The 12-year workmanship warranty is shorter than the growing premium standard in the TOPCon segment, where some competitors offer 15 or even 25 years of product warranty alongside the same 30-year power warranty. ## About this series Q-SUN Solar QNN182-HG-54 panels are an advanced solution based on **TOPCon N-Type** technology, which guarantees higher efficiency compared to standard P-type modules. The use of bifacial cells enables energy generation from the rear side of the panel as well, which significantly increases total energy yield, especially on light-colored surfaces. Thanks to the **Full Black** aesthetics, these modules combine powerful parameters with an elegant appearance, making them an ideal choice for modern home installations where design is just as important as power. The **Half-Cell** architecture effectively minimizes power losses resulting from partial shading and reduces thermal stress, which translates into higher reliability of the entire installation. The use of N-type silicon ensures that the panels show minimal degradation over time, providing a stable return on investment for many years. **Bifacial energy generation** and half-cut cell technology allow for maximum utilization of available space, setting this series apart from market competition. This product is dedicated to conscious investors who seek **exceptional resistance to weather conditions** and want to avoid compromises between aesthetics and advanced engineering. It solves the problem of limited mounting space, offering a significantly higher yield from every square meter of the roof while maintaining its minimalist style. ## Notable figures - Efficiency of 23.0% is 0.5pp above the \*\*TOPCon 450-500W\*\* median (22.5%) - Power density of 230.4 W/m² packs 5.2 W/m² more into the same footprint vs \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 450-500W\*\* median - In the top 12% for efficiency among all TOPCon panels ## Questions ### What warranty comes with the Q-SUN Solar QNN182-HG-54 panels? The QNN182-HG-54 series is backed by a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The power guarantee ensures the modules maintain a specified minimum performance level for three full decades, giving homeowners and investors confidence that the system will deliver a solid, predictable return on investment throughout its entire service life. ### How does TOPCon technology in the QNN182-HG-54 compare to conventional PERC cells? TOPCon (Tunnel Oxide Passivated Contact) uses N-Type silicon, delivering higher conversion efficiency and significantly lower light-induced degradation (LID) than P-Type PERC cells. The QNN182-HG-54 modules also exhibit a better temperature coefficient and stronger resistance to potential-induced degradation (PID). The result is a lower LCOE advantage: less cumulative power loss over the 30-year warranty period compared to PERC-based alternatives on the market. ### How much extra energy can I expect from the bifacial cells in the QNN182-HG-54? The bifacial cells in the QNN182-HG-54 harvest irradiance from both the front and rear of the module. On highly reflective surfaces such as white gravel, light-colored metal roofing, or snow, the rear-side gain typically ranges from 5% to 25% compared to a standard monofacial panel. The actual yield boost depends on the albedo of the mounting surface and the tilt angle and mounting height of the array. ### Does the Full Black design of the QNN182-HG-54 reduce panel efficiency? The all-black frame, backsheet, and cells give the QNN182-HG-54 a sleek aesthetic suited to modern rooftops. While dark surfaces can absorb slightly more heat, the N-Type TOPCon cell technology provides a better temperature coefficient than standard P-Type PERC modules. In practice, this offsets any heat-related losses, keeping output high even on hot summer days without meaningful compromise between appearance and performance. ### How does the half-cut cell architecture in the Q-SUN Solar QNN182-HG-54 handle partial shading? In a half-cut layout, each cell is split in two, reducing internal resistance and limiting the power loss caused by partial shading. If a chimney, antenna, or overhanging branch shadows part of a QNN182-HG-54 module, the unshaded cells continue generating at full capacity. This makes the series a practical choice for residential rooftops with typical obstructions, delivering noticeably higher output than full-cell modules under the same conditions. ### Are the 450 Wp Q-SUN Solar QNN182-HG-54 panels suitable for a standard home installation? Yes. At 450 Wp, the QNN182-HG-54 modules sit firmly in the high-power segment well-suited for single-family homes. A typical 6-10 kWp residential system requires only 13-23 panels, far fewer than older 300-350 Wp modules would need. Fewer panels translate to lower racking and labor costs, simpler string wiring, and a cleaner roofline, making this series a highly practical choice for prosumer PV installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/full-black-qnn182-hg410-450-54-fdc1f08a039d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +1.5 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +1.5 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +1.5 pp | | [Q-SUN Solar QNM182-HS395-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs395-54) | 395 W | -55 W, -2.8 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS400-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs400-54) | 400 W | -50 W, -2.5 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS405-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs405-54) | 405 W | -45 W, -2.3 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS410-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs410-54) | 410 W | -40 W, -2.0 pp, -5 yr warranty | | [Q-SUN Solar QNM182-HS415-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs415-54) | 415 W | -35 W, -1.7 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +55 W, cooler, +1.7 pp | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg450-54 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
