Shinson Technology S.blade series photovoltaic panels utilize innovative shingled technology, which eliminates traditional busbar connections between cells. Thanks to overlapping cells, these modules offer maximum utilization of the active surface area, which directly translates into higher energy yield per square meter. This solution effectively reduces the risk of micro-cracks and minimizes energy losses resulting from shading, which is crucial in dense urban areas. Shingled cell technology makes the panels exhibit much better aesthetics, creating a uniform, almost black surface, ideal for modern architecture. The S.blade design is also characterized by a low temperature coefficient, allowing for stable operation even on hot days. This series is dedicated to investors seeking uncompromising performance and increased resistance to mechanical loads, such as snow or strong wind. By choosing S.blade, the user receives a product that stands out from the competition not only due to its unique appearance but above all due to increased tolerance to partial shading, which optimizes the operation of the entire system in difficult installation conditions. It is an excellent choice for residential and commercial installations where every watt of power counts.

Common questions

6 answered
How does the shingled cell technology in Shinson S.blade panels differ from conventional PV modules?
In S.blade modules, cells overlap like slate roof shingles, eliminating the metal busbars between them. This maximizes the active surface area, resulting in higher energy yield per square meter. Removing busbars also reduces the risk of microcracks and minimizes power losses caused by partial shading of individual cells.
What warranty does Shinson Technology offer on the S.blade series?
Shinson Technology backs the S.blade series with a 30-year product warranty covering physical and material defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees a defined performance level for three full decades — one of the longest warranties available in the PV market.
Are Shinson S.blade panels bifacial, and does that matter for a pitched-roof installation?
Yes, the S.blade series are bifacial modules — electricity is generated on both sides of the panel. On a typical pitched roof, the rear side captures light reflected from the roofing surface or surroundings, which can add a few percent to total yield. The greatest bifacial gains come from ground-mount or flat-roof installations with a high-albedo surface beneath the array.
How do Shinson S.blade panels handle partial shading from a chimney, antenna, or dormer window?
Thanks to the shingled cell architecture and the absence of conventional busbars, S.blade modules show improved tolerance to partial shading compared to standard panels. Shadowing one section of the module does not suppress the entire cell string as severely as in traditional designs — a critical advantage in dense urban environments where shading is hard to avoid.
What is TOPCon technology used in the S.blade cells, and what real-world benefits does it provide?
TOPCon (Tunnel Oxide Passivated Contact) is an advanced cell technology in which a thin tunnel oxide layer minimizes charge-carrier recombination. The result is higher conversion efficiency and a lower temperature coefficient compared to PERC cells. TOPCon panels perform better at high summer temperatures, translating into greater annual energy yield even in temperate climates.
What is the peak power of Shinson S.blade panels, and how many modules do I need for a home installation?
S.blade panels reach a peak output of 365 Wp. A standard residential system of 5–10 kWp requires between 14 and 28 modules. The high efficiency of TOPCon cells combined with shingled technology means S.blade delivers more energy from the same roof area than typical PERC panels — a key advantage whenever mounting space is limited.
