The Solar N Plus Cygnus SP-M10/108HG solar panel series introduces a new quality to prosumer and commercial installations, focusing on advanced N-type TOPCon technology. Choosing this solution is primarily an investment in higher energy conversion efficiency and significantly slower degradation over time compared to traditional P-type cells. A key feature of the series is the bifacial glass-glass construction, which not only extremely strengthens the module's mechanical resistance to harsh weather conditions but also allows for generating additional energy from reflected radiation. Thanks to the use of M10 wafers and SMBB technology, these panels effectively eliminate the problem of energy losses due to shading and minimize the risk of micro-cracks. For the installer and investor, this means a higher yield per square meter while maintaining long-term system stability. Cygnus SP-M10/108HG modules are perfectly tailored for modern residential roofs, where aesthetics and maximum current efficiency in diffused light conditions matter. It is a reliable alternative to standard modules, offering an excellent temperature coefficient, which translates into real savings even on hot days, setting this product apart from the competition through minimal LID and LeTID degradation.

Common questions

6 answered
Do the Solar N Plus Cygnus SP-M10/108HG panels use N-type TOPCon or PERC cell technology?
The Cygnus SP-M10/108HG series is built on N-type TOPCon cell technology, which delivers higher conversion efficiency and significantly slower degradation compared to conventional PERC cells. N-type cells are inherently resistant to both LID and LeTID degradation, resulting in measurably higher energy yield over the full lifetime of the installation and a better return on investment.
What warranty does the Solar N Plus Cygnus SP-M10/108HG come with?
Solar N Plus provides a 12-year product warranty on Cygnus SP-M10/108HG modules. In addition, a 30-year linear power warranty guarantees that the panels will maintain their declared output for three full decades. Both warranty terms are comparable to those offered by leading manufacturers and are a key factor when calculating the long-term ROI of a photovoltaic system.
What does the bifacial glass-glass design of the Cygnus SP-M10/108HG mean for a rooftop installation?
The bifacial glass-glass construction of the SP-M10/108HG series allows the panel to generate power from both direct irradiance on the front side and reflected irradiance on the rear side. The dual-glass encapsulation also significantly improves mechanical resistance to hail, snow loads, and moisture ingress. The bifacial energy gain is highest on installations with a highly reflective surface underneath the modules, such as a white roofing membrane or light-colored gravel.
Do the 415 Wp Solar N Plus Cygnus panels lose a lot of power on hot summer days?
The Cygnus SP-M10/108HG series features an excellent temperature coefficient, meaning it loses less power at elevated ambient temperatures than standard modules. N-type TOPCon technology naturally provides a more favorable temperature coefficient than P-type cells, so these panels generate measurably more energy during hot summer days than their rated output might suggest, translating into real savings on electricity bills.
What is LID/LeTID degradation, and why are Cygnus SP-M10/108HG panels resistant to it?
LID (Light Induced Degradation) and LeTID (Light and elevated Temperature Induced Degradation) are power loss processes that affect P-type cells during the first months of operation. The N-type TOPCon cells used in the SP-M10/108HG series are inherently immune to both mechanisms, ensuring the module retains higher power output throughout its entire service life and delivers real financial savings over a 25-30 year horizon.
Solar N Plus isn't a Tier 1 manufacturer — is that a risk when buying Cygnus SP-M10/108HG panels?
Tier 1 classification reflects a manufacturer's financial capacity to secure project financing, not a direct measure of product quality. Solar N Plus does not appear on the major PV market Tier 1 lists. Before purchasing, verify the local distributor's warranty support, service network availability in your country, and existing installation references. The 12-year product warranty and 30-year power warranty are, however, comparable to those offered by leading Tier 1 brands.
