**Q.ANTUM DUO Z zero-gap architecture** - The near-zero-gap layout of half-cut cells increases cell packing density on the module surface, boosting energy yield per roof area and improving performance under partial shading (e.g., from chimneys or antennas) compared to conventional full-cell modules. - **Degradation-mitigating technologies** - Anti LID and Anti PID minimize the typical power-loss mechanisms over time, while Hot-Spot Protect guards the module against uneven cell loading - real protection for long-term output across the 25-year service life. - **Tier-1 bankable manufacturer** - Hanwha Q-Cells (South Korea, founded 1999) holds a BNEF Tier-1 rating and one of the world's largest module manufacturing capacities, easing project financing and providing brand stability despite this particular series being discontinued. - **Up to 20.6% efficiency - above peers** - Peak efficiency of 20.6% outperforms comparable modules in the segment, such as Solitek SOLID Bifacial (19.57%) and Solarwatt vision GM 3.0 style (19.9%), and is close to Selfa SV120M.3.2 (20.3%) - a strong result for 2021-era PERC technology. - **All-black aesthetic design** - The all-black finish blends well with modern pitched-roof architecture, making the series a good fit for premium residential installations without sacrificing performance. ## Cons - **Production discontinued in 2023** - The Q.PEAK DUO BLK-G10+ series was phased out (released 2021, discontinued 2023), limiting availability for expanding existing arrays and potentially slowing warranty claims requiring matching replacement modules. - **PERC technology superseded by N-type** - By the time the series was discontinued (2023), the market had already shifted toward N-type cells (TOPCon/HJT), offering lower annual degradation and extended linear warranties up to 30 years - the series' standard 25/25-year warranty is solid but no longer best-in-class. ## About this series The Q-Cells Q.PEAK DUO BLK-G10+ series was designed to maximize yield from the same roof surface - thanks to a half-cut cell configuration and the Q.ANTUM DUO Z architecture with its virtually seamless arrangement, the module more effectively utilizes available space and performs better under real-world operating conditions. In practice, this means more stable energy production, even when partial shading (e.g., from a chimney, antenna, or tree) appears on the installation, or under weaker sunlight and temperature fluctuations. A key feature of this series is its commitment to longevity - **Anti LID** and **Anti PID** limit common degradation mechanisms, while **Hot-Spot Protect** helps safeguard the module against uneven stress. Additionally, **Tra.Q** supports quality identification, which is important for investments that last. It is a reliable choice for aesthetically pleasing residential installations and prestigious rooftops - the **full-black** appearance integrates better with modern architecture while simultaneously not compromising on performance. ## Notable figures - At 19.5% efficiency, this panel is on par with typical \*\*PERC 0-400W\*\* modules - Power density of 195.1 W/m² matches the \*\*PERC 0-400W\*\* median - Temperature coefficient of -0.34%/°C matches the \*\*PERC 0-400W\*\* median - #12751 for efficiency, #8846 for temperature performance out of 14129 panels ## Questions ### Is the Q-Cells Q.PEAK DUO BLK-G10+ series still available for purchase? The Q.PEAK DUO BLK-G10+ series has been discontinued and is no longer manufactured by Q-Cells. Availability depends entirely on remaining distributor stock. If you need a similar all-black module with comparable specs, it is worth asking about newer Q-Cells lines such as the Q.PEAK DUO BLK ML-G10+, which offer higher wattages and current manufacturer warranties. ### What warranty does the Q-Cells Q.PEAK DUO BLK-G10+ 370W come with? Q-Cells provides a 25-year product warranty covering materials and workmanship, plus a 25-year linear power output warranty. This means module power output is guaranteed not to fall below specified thresholds over the full warranty period. Anti LID and Anti PID technologies help minimize typical degradation mechanisms, supporting long-term performance retention throughout the warranty term. ### How well do Q.PEAK DUO BLK-G10+ panels handle partial shading from a chimney or antenna? The BLK-G10+ series uses half-cut PERC cells arranged in the Q.ANTUM DUO Z zero-gap layout. Splitting each cell in half reduces resistive losses in shaded sections, allowing unshaded cells to keep producing efficiently. Hot-Spot Protect further guards the module against overheating at unevenly illuminated spots - a common issue near chimneys, antennas, or nearby trees. ### What is Q.ANTUM DUO Z technology and how does it differ from standard PERC? Q.ANTUM DUO Z is Q-Cells' proprietary implementation that combines PERC with a half-cut cell layout and a zero-gap cell arrangement. Standard PERC boosts efficiency via rear-surface light reflection, while Q.ANTUM DUO Z additionally minimizes inactive module surface area and lowers internal resistance. The result is module efficiency exceeding 20% with solid low-light and high-temperature performance. ### Does the all-black design of the Q.PEAK DUO BLK-G10+ negatively impact power output? The impact is negligible in practice. The black frame and black backsheet absorb slightly more heat than standard white components, which can cause a minor power reduction at very high ambient temperatures. Q-Cells offsets this with advanced cell technology, achieving up to 20.9% efficiency. For typical residential installations the difference is insignificant, while the aesthetic benefit on dark-tiled or flat roofs is considerable. ### How do Q.PEAK DUO BLK-G10+ modules handle heavy snow loads and strong wind? The high-tech aluminum alloy frame is rated for snow loads up to 5,400 Pa and wind loads up to 4,000 Pa. This covers heavy wet snow typical of central European winters. The modules are IEC-certified, confirming suitability for Polish climatic conditions, including mountain regions with elevated snow load requirements. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/qcells-data-sheet-q-peak-duo-blk-g10-series-350-370-da-2022-22a5e1a7c72f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +3.8 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.6 pp | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | -50 W, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +30 W, +3.5 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +50 W, +3.5 pp, +5 yr warranty | | [Q-Cells Q.PEAK DUO BLK-G10+ 355](https://comparepv.com/panel/hanwha-q-cells-america-inc-q-peak-duo-blk-g10-355) | 355 W | +0.3 pp | | [Q-Cells Q.PEAK DUO BLK-G10+ 360](https://comparepv.com/panel/hanwha-q-cells-america-inc-q-peak-duo-blk-g10-360) | 360 W | +10 W, +0.6 pp | | [Q-Cells Q.PEAK DUO BLK-G10+ 365](https://comparepv.com/panel/hanwha-q-cells-america-inc-q-peak-duo-blk-g10-365) | 365 W | +15 W, +0.8 pp | | [Q-Cells Q.PEAK DUO BLK-G10+ 370](https://comparepv.com/panel/hanwha-q-cells-america-inc-q-peak-duo-blk-g10-370) | 370 W | +20 W, +1.1 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +160 W, cooler, +5.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +145 W, cooler, +5.3 pp | --- Source: https://comparepv.com/panel/hanwha-q-cells-america-inc-q-peak-duo-blk-g10-350 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
