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, delivering not only greater performance but also a well-thought-out design that blends harmoniously into any architectural setting. Thel Mono S4 Halfcut BC Black model, with transparent inter-cell spaces, offers even higher output, as does, in particular, our top performer, the Mono S4 Halfcut BC White with white inter-cell spaces – the top-efficiency module! We have also added the compact Mono S5 Halfcut BC Installer Series Full Black to our range, designed specifically for repowering, sloping roofs and balcony installations.

Features of our Back Contact Series

L
Rear contacting

The electrical conductor paths are contacted on the back of the cell – for more light absorption on the front.

L
Reduced hot spot formation

More even power distribution reduces the risk of hot spots.

L
N-Type technology

Advanced cell technology with extremely low degradation and higher energy yields even at high temperatures.

L
Robust double-glazed design

Increased mechanical strength, better resistance to environmental influences and longer service life.

L
Minimized electrical losses

Shorter cable runs reduce resistance and increase
efficiency.

L
Increased mechanical stability

Better load capacity of the cells due to reduced material stresses

L
Bifaciality

Energy generation on the front and back of the modules – for up to 30 % additional yields, depending on the installation environment.

L
Long-term guarantees

A 30-year product guarantee and 30-year performance guarantee ensure reliable use for decades.

Anti Shading Technology

Whether it’s a tree, a chimney or a cloud – partial shading is perfectly normal.
 Our anti-shading technology ensures that your solar system still makes the most of every ray of sunshine. For consistently high performance on your roof

Conclusion

With the Mono S4 Halfcut BC series, you get solar modules that impress with their outstanding efficiency, first-class design and exceptional durability. The combination of innovative back-contact technology, N-type cells, a double-glazed construction and bifacial power generation makes our modules the ideal choice for future-proof and high-performance solar solutions.
