The SKT345-365M10 series panels are based on advanced M10-type monocrystalline cells, which represent an optimal balance between modern architecture and ease of installation on standard roof surfaces. A key distinguishing feature of this line is the use of Half-Cut Cell technology, which significantly reduces energy losses resulting from internal resistance and improves the efficiency of the entire system in partial shading conditions. Thanks to the split cells, the modules operate at a lower temperature, which directly translates into their longer lifespan and yield stability on hot days. The use of multi-layer Multi-Busbar (MBB) technology significantly shortens the current flow path, which not only increases efficiency but also effectively minimizes the risk of micro-cracks in the silicon structure. This series was designed for private investors seeking an elegant Full Black design and high power density in limited spaces. The robust frame construction guarantees increased resistance to extreme snow and wind loads, which sets these products apart from less durable competitor solutions. By choosing these panels, the user receives a product highly resistant to potential-induced degradation (PID) that perfectly suits the specifics of the Polish climate, offering maximum fire safety and reliability for decades of operation.

Common questions

6 answered
How does the TOPCon technology in the SKT345~365M10 series differ from standard PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) cells feature an ultrathin silicon oxide layer that significantly reduces carrier recombination, resulting in higher module efficiency and slower long-term degradation compared to conventional PERC cells. The SKT345~365M10 series reaches up to 365 Wp precisely because of this architecture, delivering better energy yield per square meter of roof space.
What warranties come with the Sunket SKT345~365M10 panels?
Sunket provides a 12-year product warranty covering manufacturing defects and material failures. In addition, a 25-year linear power output warranty guarantees that the module will not degrade below the specified power curve. For residential prosumer installations, this ensures predictable yield throughout the entire loan or subsidy repayment period.
Are the SKT345~365M10 Full Black panels a good fit for sloped roofs with limited surface area?
Yes, the M10 Full Black variant is particularly well suited for sloped roofs where both aesthetics and power density matter. The all-black frame and backsheet blend with most roofing materials, while the M10 cell format allows efficient use of available roof area. The half-cut cell layout also limits losses caused by partial shading from chimneys or dormers.
How do the Sunket SKT345~365M10 panels perform during winter and in the cold climate typical of Poland?
PV panels, including the TOPCon-based SKT345~365M10 series, generate electricity year-round. Low temperatures actually benefit silicon cell efficiency, since output power increases as operating temperature drops. The reinforced frame is rated for elevated snow and wind loads, meeting the structural requirements of Central European winter conditions.
Are the SKT345~365M10 panels resistant to Potential Induced Degradation (PID), and why does it matter for Polish installations?
Yes, the SKT345~365M10 series is engineered with high PID resistance. PID can reduce module output by over ten percent within a few years, especially in systems where the inverter operates with a grounded pole — a common configuration in Polish residential installations. Strong PID resistance directly protects long-term energy yield and the overall return on investment.
Does the Multi-Busbar (MBB) technology in the SKT345~365M10 series genuinely improve panel durability?
Yes. MBB technology distributes current flow across a larger number of thin conductors, shortening the electrical path and reducing mechanical stress within each cell. The result is significantly lower risk of microcracks during shipping, installation, and long-term operation. For the end user, this translates into more stable power output across the full 25-year power warranty period.
