3S Solar Railings : A power plant and fall protection system in one

Whether it’s a traditional apartment building, an upscale country villa, a conventional single-family home, or state-of-the-art exposed concrete architecture - the design of the 3S solar railings adapts to any architectural style.

The 3S solar railings are certified BIPV solutions. They replace conventional railings, generate electricity on both sides, and meet the requirements for barrier glazing. The glass-glass module with embedded solar cells provides sufficient privacy while remaining pleasantly translucent. The modules are also available in various colors as well as in a low-glare version. Additional design elements and flexible mounting options facilitate easy integration into a variety of architectural concepts.

The advantages of 3S solar railings

The 3S solar railings combine certified fall protection with highly efficient energy generation—optimized for architectural flexibility, seamless integration, and custom design.

Ecological

Generates sustainable solar energy on both sides while replacing traditional balcony railings.

Aesthetic

Blends seamlessly with any architectural style - from classic apartment buildings to modern exposed-concrete architecture - and can be customized in color.

Powerful

Thanks to bifacial modules with active cells on both sides, energy is generated from all directions - including from the reflections off the facade.

Safe

Meets the requirements for barrier glazing in accordance with DIN 18008-4:2013, as well as all standards for solar modules. The handrail contains no electrical components.

Robust

It meets hail resistance class HW 4, is self-cleaning thanks to its frameless design, and features durable, hot-dip galvanized, and powder-coated material.

Economical

It reduces energy costs, increases property value, and is low-maintenance, durable, and high-performance. Solar balcony railings can generate up to 50% of a household’s electricity needs.

Flexible

Adapts to any railing size thanks to its accordion principle. Can be mounted on top or on the front, including with concealed fasteners.

Customisable

Handrails, rails, and posts in the color of your choice can be complemented with design elements such as infill bars or panels. All RAL colors available.

Made in Switzerland

Developed and manufactured in Switzerland using carbon-neutral electricity—ensuring short transport routes and the highest quality.

A high-performance solar module for the 3S railings

A solar balcony railing generates approximately 50% of the electricity needed in the household. Thanks to its double-sided active cells, the 3S solar balcony railing efficiently captures solar energy from all directions - even from reflections off the building’s facade.

Frequently Asked Questions

  • What is an integrated solar balcony railing?

    An integrated solar balcony railing completely replaces a conventional balcony or patio railing while also generating solar power. The solar modules serve both as a fall protection barrier and as a power generator.

  • How much electricity do solar balcony railings generate?

    3S solar balcony railings can generate about 50% of a household’s electricity needs. The exact output depends on the length of the railing, its orientation, and local sunlight conditions.

  • Can the solar balcony railings be customized to fit my building?

    Yes. Thanks to the accordion principle, the spacing between posts, modules, and design elements is flexible. Handrails, rails, and posts are available in custom colors, and with additional infill bars or panels, any railing dimension can be achieved.
