That's a strong result for the lower-cost PERC platform. - **Half-cut cells with multi-busbar (MBB) structure** - Splitting cells in half combined with the MBB layout shortens the current path, reducing resistive losses and limiting the impact of partial shading - relevant for the dense single-family housing typical of the Polish market. - **High resistance to PID degradation** - The manufacturer claims enhanced resistance to potential-induced degradation (PID), translating into more stable energy yield over the long-term operation of the installation. - **Reinforced frame for snow and wind loads** - A robust frame and reinforced glass provide resistance to the snow loads and strong wind gusts typical of the Polish climate, reducing the risk of micro-cracks and mechanical failures. ## Cons - **Discontinued production - limited availability** - The QNM182-HS-54 series has been discontinued by the manufacturer, meaning limited availability of matching replacement units for warranty claims or expansion of an existing installation with the same model. - **Product warranty shorter than market standard** - A 12-year product warranty is noticeably shorter than the 20-30-year warranties now offered by leading Tier-1 manufacturers, which may affect the perceived long-term value of the investment. - **Manufacturer not on the BNEF Tier-1 list** - Q-SUN Solar (founded 2014, China) does not appear on BNEF's Tier-1 manufacturer list, which may complicate obtaining bank financing or leasing that requires bankable components in the project. ## About this series The Q-SUN Solar QNM182-HS-54 photovoltaic panel series is a solution designed to maximize yields from limited roof space. Thanks to the use of advanced **Half-Cut cell technology**, these modules effectively minimize energy losses resulting from local shading, which is crucial in Polish single-family housing. The use of a **multi-busbar (MBB) structure** significantly shortens the current flow path, which directly translates to lower component heating and a longer lifespan for the entire system. These products stand out for their exceptional resistance to voltage degradation, ensuring stable operation for many years. For the prosumer, this means **higher efficiency in low-light conditions**, which in our climate is an invaluable asset during cloudy days. The solid frame construction and reinforced glass guarantee high resistance to snow loads and strong wind gusts. This is an ideal choice for those looking for a **balance between aesthetics and technical parameters**, suitable for demanding home installations. Q-SUN Solar QNM182-HS-54 stands out from the competition with its precise workmanship, allowing for higher power density while maintaining full **operational reliability** in harsh environmental conditions. ## Notable figures - 21.3% module efficiency - 0.7pp better than the \*\*PERC 400-450W\*\* median of 20.6% - At 212.5 W/m² power density, this panel generates 6.3 W/m² more per unit area than \*\*PERC 400-450W\*\* median (206.2 W/m²) - Temperature coefficient of -0.32%/°C vs median -0.35%/°C means ~1% less power loss at 65°C - At 20.8 kg, this panel is 1.2 kg lighter than \*\*PERC 400-450W\*\* median (22.0 kg) - easier handling during installation - Ranked #8519 out of 14005 panels for efficiency in the database ## Questions ### Is the Q-SUN Solar QNM182-HS-54 series still available for purchase? The QNM182-HS-54 series has been discontinued and is no longer available through regular distribution channels. If you need similar specs — PERC technology, half-cut cells, up to 415 W — ask your distributor about current production alternatives or check remaining stock with authorized resellers who may still carry leftover inventory. ### What warranty does the Q-SUN Solar QNM182-HS-54 come with? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty protecting against excessive degradation. After 25 years, modules should retain approximately 80–83% of their rated power output, which is the industry standard for quality PERC modules in this class. ### What is half-cut cell technology in the QNM182-HS-54 and what are the real-world benefits? Half-cut technology splits standard PERC cells in half, lowering resistive losses and reducing heat buildup within the module. In practice, this improves performance under partial shading — for example from chimneys or dormers — and keeps the module cooler on hot sunny days. The QNM182-HS-54 series pairs half-cut cells with a multi-busbar (MBB) structure, further shortening current paths and extending system lifespan. ### Do Q-SUN Solar QNM182-HS-54 panels perform well on cloudy days and during the winter? Yes. The combination of PERC cells and half-cut technology gives the QNM182-HS-54 series above-average low-light performance, which is particularly valuable during Poland's overcast autumn and winter months. The reinforced aluminum frame and tempered glass provide strong resistance to snow loads and high wind gusts, keeping the installation running reliably year-round without mechanical damage risk. ### What is the maximum power output of the QNM182-HS-54 series and is it enough for a typical single-family home? The series covers a peak power range of 395 W to 415 W (STC conditions). A typical single-family home consuming 3,000–5,000 kWh per year generally needs 8 to 14 of these panels, translating to a 3.2–5.8 kWp system. The exact number depends on your location's solar irradiance, roof pitch and orientation, and the available roof area. ### Is Q-SUN Solar a Tier 1 manufacturer, and should I be concerned about panel quality? Q-SUN Solar does not appear in Tier 1 rankings published by independent financial analysts. This does not automatically mean low quality — the QNM182-HS-54 holds standard industry certifications (IEC 61215, IEC 61730). However, it is worth carefully reviewing the warranty terms, as warranty service accessibility tends to be more limited with smaller manufacturers compared to leading Tier 1 brands. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/QNM182-HS395-415-54-Black-1-1-bded85fcae36.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +50 W, +2.5 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +45 W, +2.3 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-465m-182r188-108-gg) | 465 W | +50 W, +2.3 pp, +5 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +45 W, +2.3 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | Cooler, +2.2 pp, +5 yr warranty | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +45 W, +2.2 pp, +5 yr warranty | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | Cooler, +2.2 pp, +5 yr warranty | | [Q-SUN Solar QNM182-HS395-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs395-54) | 395 W | -20 W, -1.1 pp | | [Q-SUN Solar QNM182-HS400-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs400-54) | 400 W | -15 W, -0.8 pp | | [Q-SUN Solar QNM182-HS405-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs405-54) | 405 W | -10 W, -0.6 pp | | [Q-SUN Solar QNM182-HS410-54](https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs410-54) | 410 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +80 W, cooler, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +90 W, cooler, +3.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +75 W, cooler, +3.2 pp | --- Source: https://comparepv.com/panel/qn-solar-pv-limited-qnm182-hs415-54 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
