The Solar N Plus CYGNUS All-black Bifacial (SP-M10/108HG) series is designed for investors who want to combine aesthetics with real energy gains. Its key feature is the bifacial design - the panel can also generate power from reflected light from the ground, which helps to increase output in areas with reflective surfaces or on roofs with appropriate reflection. The use of PERC technology ensures stable performance under varying solar conditions, while the 108-cell layout makes it easy to design compact installations on typical roof structures.

It is a good choice where appearance is important - the all-black finish is ideal for modern roofs and facades, minimizing the contrast between the frame and the cells. The CYGNUS series is particularly recommended for residential installations, smaller commercial systems, and projects where reliability and long-term energy production predictability are essential. Its bifacial design and refined black finish differentiate it from many standard modules, which focus solely on parameters at the expense of aesthetics.

Common questions

6 answered
Is the Solar N Plus CYGNUS All-black Bifacial SP-M10/108HG suitable for a sloped roof?
Yes, the CYGNUS SP-M10/108HG series works well on sloped roofs. The 108-cell layout fits standard roof sections comfortably, and the compact form factor simplifies transport and installation. Keep in mind that bifacial gain on sloped roofs is lower than in ground-mounted systems — rear-side energy production depends on ground albedo. Best results come from light-colored surfaces or white roofing membranes beneath the array.
What is the warranty on the Solar N Plus CYGNUS All-black Bifacial panels?
The manufacturer provides a 15-year product warranty covering physical defects and a 30-year power output warranty. Over 30 years, the panel must maintain the minimum performance level defined by the degradation curve in the datasheet. This is a solid warranty range for the mid-range segment. Before purchasing, ask your distributor for written warranty terms and confirm that after-sales support is available in your region.
What does bifacial mean in the CYGNUS series and how much extra energy can I realistically expect?
A bifacial panel has an active rear side that absorbs light reflected from the ground. In the CYGNUS SP-M10/108HG series, PERC technology supports this effect. With adequate albedo — light gravel, concrete, or white TPO/PVC membrane — the rear side can contribute 5–10% additional energy above the nominal 415 Wp rating. On a standard dark roof the gain will be lower, but still measurable.
Does the all-black version of the CYGNUS series produce less energy than a standard silver-framed panel?
The black frame and black backsheet absorb slightly more heat than lighter-colored components, which at extreme temperatures can marginally reduce instantaneous efficiency. In practice the difference is around 1–2% and is negligible in the annual energy balance under typical Central European conditions. For most homeowners, the aesthetic advantage — a uniform look with no contrast between frame and cells — fully offsets this minor trade-off.
How many CYGNUS 415 Wp panels do I need to build a 10 kW system?
At 415 Wp per module you need 25 panels, yielding approximately 10.4 kWp total. This is an approximate figure — the final design depends on roof orientation, tilt angle, inverter selection, and any shading present. Have your installer calculate the optimal string configuration and verify that the chosen inverter's MPPT voltage range matches the string voltage of 25 series-connected modules.
Is Solar N Plus a reliable manufacturer and do the CYGNUS panels carry the required certifications?
Solar N Plus is not listed among Tier 1 manufacturers according to Bloomberg NEF, indicating a smaller production scale than market leaders. CYGNUS series panels should carry IEC 61215 and IEC 61730 certifications required for EU installations. Before purchasing, request up-to-date certificates in PDF format from your distributor and confirm that warranty service is available in your country.
