The use of **half-cut cells** and **multi-bin MBB architecture** improves performance under partial shading and reduces losses due to microcracks, which translates in practice to more stable energy production in Polish conditions. CYGNUS also stands out for its **high efficiency in low-light conditions** - even with cloudy weather and in winter, the system can generate more energy than many competing modules of the same class. This means shorter payback periods and better predictability for investors. It is a good choice for residential and commercial installations, as well as for larger projects where consistent quality and resistance to operating conditions are important. Thanks to its **enhanced PID resistance**, CYGNUS helps to minimize the risk of performance degradation over the long term, especially in higher-voltage installations. ## Notable figures - At 20.2% efficiency, this panel is 1.6pp below the \*\*database\*\* median of 21.8% - At 202.3 W/m², this panel generates 15.8 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.35%/°C temperature coefficient - 0.05pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - 21.0 kg weight - 5.5 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - #11956 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the Solar N Plus CYGNUS series still available for purchase? The CYGNUS series has been discontinued and is no longer offered as a new product. If you're planning a new solar installation, ask your distributor about current replacements from Solar N Plus or other manufacturers with similar specifications. Some sales channels may still have remaining stock, but availability cannot be guaranteed. ### What warranty does the Solar N Plus CYGNUS panel come with? The manufacturer provides a 15-year product warranty covering manufacturing defects and a 30-year linear power output warranty. This means the module is expected to maintain a specified minimum output level for three decades — a solid foundation for long-term return-on-investment planning for both residential and commercial installations. ### What is half-cut cell technology with MBB architecture, and what does it mean in practice for the CYGNUS series? In CYGNUS panels, each PERC cell is cut in half, reducing operating current and resistive losses. The Multi Busbar (MBB) architecture distributes current flow across more conductive paths, so micro-cracks in individual cells have less impact on the overall module output. The practical result is more stable performance under partial shading — for example, from chimneys, dormers, or nearby trees. ### Do Solar N Plus CYGNUS panels perform well on cloudy days and during winter in Poland? Yes, the CYGNUS series is rated for high efficiency under low-irradiance conditions, which is especially important in Poland's climate with frequent overcast periods. The PERC technology combined with half-cut cells captures more energy from diffuse light on cloudy days and short winter days compared to older standard modules without these improvements. ### What is the maximum power output of the CYGNUS module and which installations is it best suited for? Solar N Plus CYGNUS modules reach a peak power output of up to 560 Wp. This makes them suitable for residential rooftop installations — where every square meter of roof space matters — as well as commercial projects that require consistent, repeatable quality at scale. The high per-panel wattage means fewer modules are needed to reach your target system capacity. ### Are CYGNUS modules resistant to PID degradation, and does it matter over the long term? Yes, the CYGNUS series features enhanced resistance to Potential Induced Degradation (PID), a gradual efficiency loss caused by high system voltage combined with moisture ingress. In higher-voltage systems — typical for commercial installations or long string configurations — PID resistance directly preserves module power output throughout the full 30-year operational lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sp-m10-108h395-415w-black-2023v2-0-094c7743c47c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | Cooler, +2.9 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.8 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 | Lighter, +2.8 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 | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.8 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | Cooler, +2.7 pp, +5 yr warranty | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | +45 W, cooler, +2.7 pp | | [Solar N Plus SP-M10/108HG-400](https://comparepv.com/panel/solar-n-plus-sp-m10-108hg-400) | 400 W | Heavier, +0.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +4.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +95 W, cooler, +4.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +105 W, cooler, +4.3 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +105 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/solar-n-plus-sp-m10-108h395w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
