3S Swiss Solar Solutions AG: Roof-integrated photovoltaics at BAU 2025
3S Swiss Solar Solutions AG is a Swiss company that has been developing and producing solar modules for over 20 years. The company offers comprehensive solar solutions for roofs, façades and balcony railings that can be seamlessly integrated into the building envelope. With innovative products such as the TeraSlate module, 3S focuses on increased efficiency and aesthetic design. The company attaches particular importance to sustainability by producing its solar modules CO₂-neutrally in Switzerland.
3S offers roof-integrated photovoltaics: aesthetics and efficiency combined
The roof-integrated photovoltaic systems from 3S set new standards in building energy supply. Unlike conventional PV systems, the modules completely replace the roof tiles and act as an independent roof cladding. This design not only offers attractive aesthetics, but also practical advantages: The modules are laid floating, which means they can be removed or maintained at any time without tools. The system comprises just three components - gutter, hooks and modules - which makes installation uncomplicated and efficient.
Performance optimization and longevity
The integrated bypass diodes are a particular highlight of the 3S modules. This technology ensures that electricity production is not impaired even if individual modules are partially shaded. In contrast to conventional systems, where shading reduces the output of an entire string, the efficiency here remains consistently high. In addition, the modules offer hail protection class 5 and can withstand hail with a diameter of up to five centimetres at a speed of 120 km/h. The weather resistance guarantee is an impressive 40 years, which underlines the durability and sustainability of the system.
Versatile application options and cost-effectiveness
The PV modules from 3S are suitable for both new buildings and roof renovations. Although the costs for renovations are around 10 % higher than for conventional tiled roofs, the investment pays for itself within five to eight years thanks to the energy savings. Thanks to the possibility of producing special modules for complex roof shapes such as hipped roofs, 3S offers a suitable solution for every roof. With over 20 years of experience and more than 20,000 completed projects, the company has established itself as a leading provider in this field.
Fast installation and specialist partner support
The installation time for the modules is minimal, as only ten to 20 minutes are required per square meter. As the specialist partners gain more experience, this time decreases further, which also increases the efficiency of the system. The ease of handling, combined with the support of certified specialist partners, makes the installation of 3S photovoltaic systems a reliable and future-proof solution for sustainable energy generation.
