The VDS-S120/M6H series utilizes advanced Half-Cut monocrystalline cells, which directly translates to higher installation efficiency in challenging lighting conditions. Thanks to the division of cells into two independent parts, these panels handle shading significantly better, minimizing energy losses that could disable entire strings in traditional modules. The implementation of Multi-Busbar technology shortens the current flow path, which not only limits internal resistance but also increases the module's mechanical resistance to micro-cracks. This solution is dedicated to investors seeking a perfect balance between modern technology and durability. Models in this series feature a low temperature coefficient, ensuring they maintain high performance even on hot summer days when standard panels lose power. VDS-S120/M6H is an ideal choice for roofs with complex geometry and commercial projects where a fast return on investment is key. The robust frame design ensures safety under heavy snow or wind loads, setting them apart from budget-friendly competitors. By choosing these modules, you gain the assurance of stable operation for years, supported by excellent build aesthetics that harmonize with modern architecture. This series effectively combines functionality with high technical excellence, meeting the requirements of the most demanding PV systems.

Common questions

6 answered
Is the VDS-S120/M6H series still available for purchase?
The VDS-S120/M6H series has been discontinued and is no longer offered as a current model. Availability is limited to remaining distributor stock. Anyone planning to expand an existing installation built on these panels should check inventory promptly, since finding a compatible replacement with the same power output and dimensions may become difficult once stock runs out.
What warranty comes with VDS-S120/M6H panels?
VDS-S120/M6H panels are covered by a 12-year product warranty against material and workmanship defects, plus a 25-year linear power output warranty. This means the manufacturer guarantees a defined performance level over a quarter century, a standard benchmark for good-quality monocrystalline panels on the market.
What is Half-Cut technology in the VDS-S120/M6H series, and is it worth choosing?
Half-Cut technology splits silicon cells into two smaller halves, reducing current losses and improving resistance to partial shading, for example from chimneys or antennas. In practice this means higher efficiency under difficult lighting conditions compared to traditional full-cell panels. It's a solid choice for roofs with obstacles that cast shadows during the day.
What is the maximum power output of the VDS-S120/M6H panel?
The VDS-S120/M6H panel reaches a maximum power output of up to 380 Wp. This is a typical value for this class of module featuring Half-Cut and Multi-Busbar technology, suitable for both residential installations and smaller commercial projects, while keeping a reasonable footprint relative to power output.
Do VDS-S120/M6H panels perform well in summer at high temperatures?
Yes, the VDS-S120/M6H series features a low temperature coefficient, meaning it loses less power output as module temperature rises compared to standard panels. In practice this results in more stable energy production on hot days, when typical silicon cells clearly lose efficiency above 25°C.
Is the VDS-S120/M6H a bifacial panel?
No, the VDS-S120/M6H series is a monofacial panel, generating energy only from its front surface. This makes it simpler to install than bifacial panels, since it doesn't require a special mounting setup to capture reflected rear-side light, making it a versatile choice for typical rooftop installations.
