Back Contact technology - the next generation of solar modules
The demands on modern solar modules are constantly increasing: maximum efficiency, attractive design, and long-term reliability are now key factors. With Back Contact technology, we offer a forward-looking solution that meets these demands and sets new standards in the solar industry. Since all the conductors are contacted on the back of the cell, the entire front surface remains free for light absorption—resulting in higher efficiency, minimized shading, and a sleek, uniform appearance. The Mono S4 Halfcut BC Full Black combines these advantages with state-of-the-art cell technology and thus not only delivers more power, but also a sophisticated design that blends harmoniously into any architecture. The Mono S4 Halfcut BC Black model with transparent cell gaps offers even more yield and, in particular, our performance tiger, the Mono S4 Halfcut BC White with white cell gaps – the top efficiency module!

Features of the Mono S4 Halfcut BC Series
Rear contacting
The electrical conductor paths are contacted on the back of the cell – for more light absorption on the front.
Reduced hot spot formation
More even power distribution reduces the risk of hot spots.
N-Type technology
Advanced cell technology with extremely low degradation and higher energy yields even at high temperatures.
Robust double-glazed design
Increased mechanical strength, better resistance to environmental influences and longer service life.
Minimized electrical losses
Shorter cable runs reduce resistance and increase
efficiency.
Increased mechanical stability
Better load capacity of the cells due to reduced material stresses
Bifaciality
Energy generation on the front and back of the modules – for up to 30 % additional yields, depending on the installation environment.
Long-term guarantees
A 30-year product guarantee and 30-year performance guarantee ensure reliable use for decades.
Anti Shading Technology
Whether tree, chimney or cloud – partial shading is quite normal.Our anti-shading technology ensures that your solar system still gets the best out of every ray of sunshine. For consistently strong performance on your roof
Conclusion
With the Mono S4 Halfcut BC series, you get solar modules that impress with maximum efficiency, first-class design and extreme durability. The combination of innovative back contact technology, N-type cells, double glass construction and bifacial energy generation makes our modules the ideal choice for future-proof and sophisticated solar solutions.
