The Sunket New Energy SKT415-435M10-108D4 series consists of advanced modules utilizing N-type TOPCon technology, which currently represents the peak of efficiency in commercial photovoltaics. Thanks to the Double Glass construction, these panels are characterized by exceptional resistance to degradation caused by atmospheric factors and significantly higher mechanical strength compared to classic solutions. A key innovation is bifaciality, allowing for the generation of additional energy from the rear side of the cells by effectively utilizing light reflected from the ground. This solves the problem of limited mounting surface, maximizing yields from every square meter of the installation. This series is dedicated to investors seeking uncompromising longevity, as N-type cell technology almost completely eliminates the LID effect, ensuring stable power for decades. Compared to standard older-generation modules, the Sunket product offers a significantly better temperature coefficient, which translates into high performance even on hot summer days. It is an ideal choice for modern home micro-installations and professional farms where the lowest levelized cost of energy matters. The use of M10 Half-Cut cells effectively reduces internal losses and minimizes the risk of hot spots, placing this series at the forefront of the safest and most profitable renewable energy solutions currently available on the Polish market.

Common questions

6 answered
What warranty comes with the Sunket SKT415-435M10-108D4 solar panels?
The SKT415-435M10-108D4 series carries a 15-year product warranty covering manufacturing defects and materials, plus a 30-year linear power warranty guaranteeing at least 87.4% of rated output at the end of the warranty period. This is among the longer power-warranty terms currently on the market and reflects the manufacturer's confidence in the long-term stability of N-type TOPCon cell technology.
What benefit does bifacial technology offer in the Sunket SKT435M10-108D4, and is it worth the premium?
Bifacial design lets the rear glass surface generate additional electricity by capturing albedo light reflected from the ground or rooftop membrane. Depending on surface reflectivity (white membrane, gravel, snow), real-world energy yield can increase by 5-15% with no extra mounting area required. The Double Glass construction also provides superior protection against moisture ingress and PID degradation, extending the module's effective service life.
Are the Sunket SKT415-435M10-108D4 panels suitable for a pitched residential roof?
Yes. The modules measure 1722×1134×30 mm and weigh approximately 21 kg, which is well within standard residential rooftop installation parameters. The 108-cell M10 half-cut configuration reduces output losses under partial shading from chimneys or roof windows, and the double-glass frame provides excellent mechanical resistance to snow and wind loads commonly specified in European installation standards.
How do the Sunket SKT435M10-108D4 panels perform during summer heatwaves?
The series carries a temperature coefficient of Pmax of -0.29%/°C, which means smaller power losses at elevated cell temperatures compared to standard PERC modules (typically -0.34 to -0.35%/°C). At a module operating temperature of 60°C, this Sunket series loses approximately 10.2% of rated power, while an equivalent PERC panel would lose 12-12.5%, translating to meaningfully higher summer yields and a lower LCOE over the system's lifetime.
How does TOPCon technology in the Sunket SKT415-435M10-108D4 compare to older PERC cells?
N-type TOPCon cells feature a tunnel oxide passivation layer that virtually eliminates Light-Induced Degradation (LID), the main cause of early-year power loss in PERC modules. This results in higher module efficiency — up to 22.27% for this series versus roughly 20-21% for typical PERC — and more stable long-term output across the full 30-year power warranty period, which directly lowers the LCOE of any system built with these modules.
What is the peak module efficiency of the Sunket SKT415-435M10-108D4 and what drives it?
The top variant in the series, the 435 Wp panel, achieves a module efficiency of up to 22.27%. Key contributors are the N-type TOPCon cell architecture, the M10 half-cut cell format that reduces internal resistive losses, and 16-busbar metallization that improves current collection across each cell. In practical terms, this higher efficiency means the same system capacity occupies less roof area than installations built with older-generation panels.
