The Sunket New Energy SKT390-415M10 photovoltaic module series utilizes advanced cells based on M10 silicon wafers, which translates into optimal power density while maintaining compact dimensions. Thanks to the use of Half-Cut cell technology, these panels handle the issue of partial shading much more effectively, minimizing energy losses in difficult installation conditions. The innovative multi-busbar design shortens the current flow path, which effectively reduces internal resistance and increases the module's resistance to micro-cracks. These models are primarily dedicated to single-family homeowners and small businesses looking for a balance between high efficiency and aesthetic design. A distinguishing feature of the series is its excellent temperature coefficient, guaranteeing stable operation even during hot summer days. Unlike standard solutions, the SKT390-415M10 series is characterized by increased resistance to potential-induced degradation (PID), ensuring long-term investment security and maintaining high yields for decades. The use of high-efficiency M10 monocrystalline cells allows for maximum utilization of the available roof area, offering more power per square meter than older types of panels. It is a solid solution for those who prioritize reliability and modern module architecture that will meet the demands of the Polish climate.

Common questions

6 answered
Is the Sunket SKT390-415M10 series still available for purchase?
The SKT390-415M10 series has been discontinued by Sunket New Energy and is no longer actively manufactured. Stock units may still be available through select distributors, but availability is limited. If you need a current equivalent from the same manufacturer, ask about newer M10-based series featuring TOPCon technology or higher-wattage PERC options.
What warranty does the Sunket SKT390-415M10 come with?
Sunket provides a 15-year product warranty covering material and workmanship defects. The linear power output warranty is considerably longer at 30 years, during which Sunket guarantees the modules will maintain a defined minimum power yield. This exceeds the industry-standard 25-year power warranty and offers solid long-term protection for your investment.
Is bifacial technology in the SKT390-415M10 worth it for a residential rooftop?
Bifacial means the panel generates electricity from both sides — the rear surface captures light reflected off the mounting substrate, such as light-colored gravel, a white membrane, or snow. On a typical pitched roof with dark tiles, the bifacial gain is modest at 3–8%. The benefit is more pronounced on flat roofs with a bright substrate or in ground-mount systems.
How does the Half-Cut PERC technology in the SKT390-415M10 handle partial shading?
Half-cut cells split each mono PERC cell in two, so shading one row does not disable the entire module string. Combined with the 10-busbar Multi-Busbar design, the SKT390-415M10 maintains higher output when a chimney, dormer window, or antenna casts a shadow — outperforming standard full-cell modules in real-world residential rooftop conditions.
How does the SKT415M10 perform on hot summer days — does high temperature significantly reduce power output?
The SKT390-415M10 series has a power temperature coefficient of -0.35%/°C. When the panel heats to 65°C (40°C above STC), output drops by approximately 14%. In practice, a 415 Wp module on a very hot day may produce around 355–360 W — a typical result for mono PERC technology and not an indication of any defect.
What type of installation is the Sunket SKT390-415M10 series best suited for?
The SKT390-415M10 series, rated up to 415 Wp and built on M10 (182 mm) cells, is designed primarily for residential prosumer systems and small commercial rooftops. Its compact footprint makes handling and installation on pitched roofs straightforward, while the higher power density delivers more energy per square meter compared to older-generation modules.
