The Sunlike Solar SKT410-430M10-108D4 panel series introduces a new quality to modern photovoltaic installations thanks to the use of advanced N-type TopCon cell technology, which effectively eliminates the problem of LID and LeTID degradation. These modules solve the investor dilemma regarding limited roof space, offering high energy conversion efficiency while maintaining optimal, compact dimensions. The unique bifacial double glass design allows for the efficient use of reflected light, which, combined with a dense busbar layout, guarantees the minimization of resistance losses and current flow. This series is dedicated to demanding residential users and businesses that prioritize maximum yields in diffuse light conditions, so characteristic of the Polish climate zone. What distinguishes these modules from standard solutions is an exceptionally low temperature coefficient, ensuring stable operation and smaller power drops during summer heat waves. Choosing this series is an investment in increased mechanical resistance and longevity, which directly translates into a faster return on investment and energy security for the building for decades to come. By combining aesthetics with innovative materials engineering, these panels provide a solid foundation for PV systems focused on reliability.

Common questions

6 answered
What is the TOPCon technology used in the Sunlike Solar SKT410-430M10-108D4 series and why does it matter?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture featuring an ultra-thin tunnel oxide layer that virtually eliminates LID and LeTID degradation phenomena found in older PERC modules. For the SKT410-430M10-108D4 series, this translates to sustained high conversion efficiency over the entire service life and no risk of unexpected power drops during the first years of system operation.
Do the Sunlike Solar SKT410-430M10-108D4 panels perform well in overcast conditions typical of Polish weather?
Yes. The SKT410-430M10-108D4 series demonstrates excellent low-light response, which is critical in the Central European climate. The bifacial double glass construction additionally harvests albedo light reflected from the ground surface, boosting annual energy yield by up to several percent compared to standard monofacial modules, making this series particularly well-matched to Poland's frequently overcast skies.
What warranty comes with the Sunlike Solar SKT410-430M10-108D4 solar panels?
Sunlike Solar provides a 15-year product warranty covering material defects and workmanship, along with a 30-year linear power output warranty guaranteeing at least 87.4% of rated power at end of life. This extended dual-warranty structure directly protects the return on investment across the full operational lifetime of the PV system.
How do high summer temperatures affect the output of the SKT410-430M10-108D4 panels?
The power temperature coefficient of this series is just -0.29%/°C, placing it among the best in its module class. When a panel heats up to 65°C on a hot summer day — 40°C above STC — the power loss amounts to only approximately 11.6%, compared to the typical 14–16% seen in standard PERC modules. This results in more stable energy production during peak summer hours and higher annual yields.
Are the bifacial SKT410-430M10-108D4 panels suitable for a typical pitched roof installation?
Yes. The modules measure 1722×1134×30 mm and weigh approximately 21 kg, making them manageable to transport and install on standard pitched roofs. The 30 mm aluminum frame is compatible with racking systems widely available across the European market. To fully leverage bifacial gain, a light-colored surface beneath the array and a roof pitch of 30–40° with south-facing orientation are recommended.
Which inverters are compatible with the Sunlike Solar SKT410-430M10-108D4 panels?
The SKT410-430M10-108D4 series delivers up to 430 Wp with an open-circuit voltage (Voc) typical of 108-cell M10 modules, making it compatible with any inverter supporting a wide MPPT input voltage window. It works well with popular string inverters available in Poland (Fronius, SMA, Huawei, Solis) as well as systems using microinverters or power optimizers.
