The Sunket New Energy SKT385-410M10 panel series is based on advanced M10-type monocrystalline cells, which enable high power density while maintaining optimal module dimensions. The use of Half-cut technology combined with a Multi-busbar system significantly reduces internal losses and improves current flow, which is crucial in partial shading conditions. These panels solve the problem of limited installation space on pitched roofs, offering high efficiency that directly translates into a faster return on investment for prosumers. A key feature of the series is high resistance to the PID effect and material degradation, which ensures the stability of electrical parameters over many years of operation in the variable Polish climate. Thanks to the use of a reinforced frame structure, the modules exhibit above-average mechanical strength against snow loads and wind pressure. This product is dedicated to private investors and companies looking for an optimal price-to-performance ratio, serving as a strong competitor to premium-type solutions. Precise quality control at every stage of production ensures that the SKT385-410M10 series guarantees failure-free system operation and predictable energy yields regardless of the season.

Common questions

6 answered
Are the Sunket SKT385-410M10 panels bifacial and do they actually generate power from the rear side?
Yes, the SKT385-410M10 series features a bifacial design — the modules generate electricity from both the front and rear surfaces. The rear side captures energy from light reflected off the ground or roof surface (albedo effect). Under Central European conditions, rear-side gains typically range from 5–15%, and can be even higher during winter months when snow cover increases ground reflectivity.
What product and power output warranty comes with the SKT385-410M10 series?
Sunket New Energy provides a 15-year product warranty covering material defects and workmanship, along with a 30-year linear power output warranty. Over those three decades, each module is guaranteed to retain at least the minimum power percentage specified in the warranty documentation. A 30-year power warranty is one of the longer commitments available in this PERC panel price segment.
What does PERC technology in the SKT385-410M10 actually mean for energy yield?
PERC (Passivated Emitter and Rear Cell) technology adds a passivation layer to the rear of each cell, reducing electron recombination and boosting conversion efficiency. In the SKT385-410M10 series this translates to module efficiency in the 19.8–21% range. Compared to conventional BSF monocrystalline cells, PERC delivers more kilowatt-hours from the same roof area, improving the LCOE of the installation.
Do the Sunket SKT385-410M10 panels handle partial shading from a chimney or dormer window well?
The SKT385-410M10 series uses half-cut cell technology combined with a 10-busbar (Multi-busbar) layout on 182 mm M10 cells. Cutting each cell in half means that shade falling on part of the panel affects only a portion of the cell string rather than the entire row. This significantly reduces power losses caused by common rooftop obstructions such as chimneys, dormer windows, or antennas.
How do the SKT385-410M10 modules perform in winter and on overcast days?
Monocrystalline PERC cells carry a negative temperature coefficient of power (approx. -0.35%/°C), meaning output is actually higher on cold winter days than during summer heat. Under diffuse light on overcast days, monocrystalline modules maintain reasonable output, though below STC-rated efficiency. The bifacial construction provides an additional winter benefit — light reflected off snow cover boosts rear-side generation.
Are the SKT385-410M10 panels suitable for a typical pitched roof in a 10–15 kWp residential prosumer system?
Yes. The SKT385-410M10 modules measure approximately 1722×1134×30 mm and weigh around 20.5 kg, making them well suited to standard gable roofs. A 10 kWp system requires roughly 25–26 panels; a 15 kWp system needs about 37–39. The reinforced aluminum frame provides the mechanical strength needed to handle snow loads and wind pressure typical of Central European climates.
