Middle of its segment, short guarantee
The Kensol KS405-410MB5-SBS series sets new performance standards thanks to the use of advanced shingled technology, which completely eliminates gaps between cells. This solution allows for maximum utilization of the available module surface, directly translating into higher energy yields even with limited installation space. A key distinguishing feature of this line is the Super Black Structure (SBS), which ensures a deep, uniform black across the entire panel, meeting the needs of the most demanding architectural projects. By replacing traditional busbars with precise adhesive connections, the modules exhibit exceptional resistance to micro-cracks and the negative impact of variable temperatures. This series effectively solves the problem of power drops caused by partial shading, offering significantly better performance characteristics in difficult lighting conditions than classic panels. It is an ideal choice for private investors who value uncompromising All Black aesthetics and long-term system reliability. By choosing these modules, you gain the certainty of stable installation operation for decades, which clearly distinguishes them from standard alternatives prone to mechanical degradation. The innovative design guarantees not only higher efficiency but also maximum resistance to extreme snow and wind loads, ensuring the safety of the entire investment.

Bottom 18% of the 305-505 W band, against a median of 30 yrs.
Overlapping cells (340 cells, 34×10 layout) eliminate busbars and inactive module surface, reducing resistive losses and increasing fill factor. The result is 405–410 W output from a 1719×1140 mm footprint — higher than conventional PERC busbar layouts at the same module geometry.
Adhesive cell interconnections replacing soldered busbars eliminate thermomechanical stress — the primary cause of microcracks in conventional modules. Segmented electrical topology results in lower mismatch losses under partial shading compared to standard 6-busbar PERC configurations.
Peak efficiency of 20.9% outperforms direct peer VDS Renewable VDS-S144/FNH (20.4%) by 0.5 percentage points, translating to approximately 2.5% higher annual energy yield per identical roof area compared to that competitor.
Compliance with IEC 61215 and IEC 61730 Class A enables unrestricted rooftop installation on residential buildings. The 5,400 Pa front load rating (~550 kg/m²) meets Polish snow load requirements for climate zones 2 and 3 per PN-EN 1991-1-3.
The Super Black Structure delivers uniform deep-black appearance across frame, glass, and cells with no visible busbars. This is a meaningful differentiator in the residential rooftop segment, where aesthetics directly influence purchase decisions on architecturally exposed roof surfaces.
The -0.34%/°C power temperature coefficient matches typical PERC performance and is inferior to N-type TOPCon modules in the same wattage class — e.g., Luxor Eco Line N-type achieves approximately -0.30%/°C. At a typical summer cell temperature of ~60°C in Poland, the 0.04%/°C gap translates to roughly 0.8–1.0% lower peak power output versus TOPCon peers.
Kensol does not appear on BloombergNEF Tier-1 solar module lists for Q1 or Q2 2026. The absence of Tier-1 status may complicate module acceptance in commercial and utility-scale projects where EPC contracts and bankability clauses typically require a BNEF-listed or equivalent manufacturer for project finance approval.
The series offers no bifacial variant, while Luxor Solar delivers a glass-glass bifacial N-type TOPCon module at the same power class (410 W) with 21.33% efficiency. On high-albedo surfaces (light paving, gravel), bifacial modules typically generate 5–15% additional energy without increasing rooftop footprint.
- At 20.7% efficiency, this panel is 1.1pp below the database median of 21.8%
- At 206.7 W/m², this panel generates 11.4 W/m² less per unit area than database median (218.1 W/m²)
- At -0.34%/°C, loses 0.04pp more power per degree than database median (-0.30%/°C)
- Weight of 21.0 kg (5.5 kg below database median of 26.5 kg) allows easier transport and roof mounting
- In the top 77% for efficiency among all N-type panels
