The Sunket New Energy SKT415-435M10-108S1 series features advanced monocrystalline modules that optimize the performance of rooftop installations while maintaining compact dimensions. Thanks to the use of Half-Cut cells and modern M10 format silicon wafers, these panels effectively minimize energy losses resulting from periodic shading and internal resistance. This solution is dedicated primarily to prosumers seeking maximum power from a limited roof area, where every square meter is crucial. The applied Multi-busbar technology shortens the current flow path and significantly reduces the risk of micro-cracks, which directly translates into longevity and yield stability in the demanding Polish climate. The series is characterized by high energy conversion efficiency, allowing for a faster return on investment compared to older generation modules. These products solve the problem of installation on complex roof surfaces, offering an excellent weight-to-power output ratio. Exceptional resistance to potential-induced degradation and increased mechanical strength against snow and wind loads make these panels a solid, reliable alternative to more expensive premium segment solutions. This is a conscious choice for installers who focus on modern cell architecture and reliable technical parameters, ensuring peace of mind for many years of operation.

Common questions

6 answered
What warranty is included with the Sunket SKT415~435M10-108S1 solar panels?
The manufacturer provides a 12-year product warranty covering workmanship and materials, along with a 25-year linear power output warranty. The panel must maintain its declared efficiency according to the degradation curve specified in the warranty documentation throughout that period. For a prosumer, this represents solid investment protection over a typical 15-year payback horizon.
What is TOPCon technology and why does the SKT415~435M10-108S1 series use it?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces carrier recombination through a thin silicon oxide passivation layer. In practice, this delivers conversion efficiency up to approximately 22% and a low temperature coefficient of power at -0.29%/°C, resulting in better energy yield during hot summer days compared to the widely used PERC technology.
Are the Sunket SKT415~435M10-108S1 panels suitable for installation on a small roof?
Yes, the SKT415~435M10-108S1 series is a strong choice when roof space is limited. Each module measures 1722×1134×30 mm and weighs approximately 20.5 kg. With up to 435 Wp per module, a 10 kWp system requires only around 56 m² of active roof area, making this series particularly efficient for residential and urban installations.
How do the SKT415~435M10-108S1 panels perform in winter and overcast conditions in Poland?
TOPCon technology features a temperature coefficient of power of -0.29%/°C, meaning that on cold, sunny winter days the panels can actually outperform their STC-rated output compared to hot summer conditions. The 108-cell half-cut layout and 16BB multi-busbar design also improve shade tolerance, which is important during winter months when the sun angle is low and partial shading from chimneys or dormers is more frequent.
How does the SKT415~435M10-108S1 series differ from older PERC modules?
N-type TOPCon cells in the SKT415~435M10-108S1 series achieve efficiency up to approximately 22%, compared to the typical 20–21% for P-type PERC. The key differences are a lower temperature coefficient and significantly slower long-term degradation due to reduced LID and LeTID effects. This translates into higher annual energy yield from the same roof area and better durability over a multi-decade service life.
Is the Sunket SKT415~435M10-108S1 panel difficult to install on a pitched roof?
No, the module weighs approximately 20.5 kg and measures 1722×1134 mm, which falls within the standard range for modules in this power class. MC4-compatible connectors enable fast and reliable string wiring, and the junction box carries an IP68 ingress protection rating. The module is compatible with standard racking systems available on the Polish market, including hook-mounted solutions designed for tile and metal roofing.
