The SKT460-480M10-120D3 solar panel series from Sunket New Energy is an advanced solution based on M10 cells, redefining efficiency standards in commercial and residential installations. The Double Glass design ensures these modules feature exceptional resistance to light-induced degradation and variable weather conditions, which directly translates to stable energy production for decades. Thanks to the use of Half-Cut technology, the panels handle shading issues significantly better, minimizing power losses in situations where part of the module is in the shade. The use of Bifacial technology allows for harvesting energy not only from direct sunlight but also from light reflected off the ground, making this series unrivaled for ground-mounted solar farms and modern roof structures. This solves the problem of limited mounting surface area, offering a higher yield per square meter compared to traditional monofacial panels. By choosing this model, investors receive a product that combines high conversion efficiency with maximum mechanical durability, setting the Sunket brand apart from standard solutions available on the market. It is an ideal choice for those seeking uncompromising quality and a fast return on investment in the Polish climate.

Common questions

6 answered
Is the Sunket New Energy SKT460~480M10-120D3 series still available for purchase?
The SKT460~480M10-120D3 series has been officially discontinued and is no longer in regular production. Some distributors may still carry limited stock, so it is worth checking directly with your local supplier before making a decision. For new installations, Sunket's current TOPCon lineup offers higher wattage options that maintain full system compatibility with inverters rated for 1500 V DC.
How do the TOPCon cells in the SKT460~480M10-120D3 panels compare to mainstream PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) technology reduces carrier recombination through a thin tunnel oxide layer, resulting in higher conversion efficiency than standard PERC cells. In practice this means more kilowatt-hours from the same roof area and better performance at elevated module temperatures. The SKT460~480M10-120D3 uses M10 (182 mm) cells with 16 busbars, which minimizes resistive losses at interconnects.
What warranty does Sunket provide for the SKT460~480M10-120D3 series?
Sunket offers a 15-year product warranty covering manufacturing defects and a 30-year linear power output warranty. Under the power warranty, the module is guaranteed to retain above a defined threshold of its rated output — typically 80–87.4% — after 30 years of operation. This is among the longer warranty terms on the market and is a meaningful factor when calculating the long-term return on investment.
Are the SKT480 bifacial panels a good fit for ground-mounted or utility-scale solar installations?
Yes, ground-mounted arrays are one of the ideal use cases for bifacial modules. The panel harvests direct irradiance on the front side and ground-reflected irradiance on the rear. On a light-colored surface such as gravel or concrete, the bifacial gain can reach 10–25% compared to a monofacial equivalent. The Double Glass construction also protects the rear surface from moisture ingress and mechanical damage throughout the full service life.
How does the half-cut M10 cell design affect the SKT460~480M10-120D3's performance under partial shading?
In a half-cut module, each cell is laser-divided in half, and the 120 half-cells are wired as two independent electrical strings. When a shadow falls on part of the panel — from a chimney, antenna, or dormer — only the shaded string loses power, not the entire module. This makes the SKT460~480M10-120D3 significantly more shade-tolerant than conventional full-cell panels where a single shaded cell can affect the entire string.
How much does the SKT460~480M10-120D3 Double Glass module weigh, and can a standard roof structure support it?
Double Glass modules in this series weigh approximately 28–32 kg each — several kilograms more than comparable backsheet modules. A qualified structural engineer should assess roof load capacity before installation. For typical pitched roofs with rafters spaced 60–80 cm apart, standard aluminum racking systems generally provide sufficient support, but each structure must be evaluated individually to confirm it meets local building and load requirements.
