With 3S Overhead, canopies become part of sustainable energy generation. The system combines high-quality glass architecture with modern photovoltaics, creating a solution that unites shelter, design, and power generation in a single element.
Whether it’s carports, parking canopies, or patios - with 3S overhead, you can make the most of your space: as a functional canopy and for generating solar power. This creates carbon-neutral energy right where, until now, the only benefit was protection from the weather and sun.
At the heart of the system is the TeraSlate glass-glass solar module. The bifacial cell technology harnesses not only direct sunlight but also light reflected from the underside, thereby enabling additional energy yields. At the same time, the robust glass-glass construction ensures exceptional durability and reliable protection for decades.
The 3S overhead is designed for maximum space utilization, high-quality glass architecture, and reliable energy generation.
Turns existing roof surfaces into sustainable energy sources. Carbon-neutral power generation right where previously only shelter was provided.
It meets hail resistance class HW 4 (hailstones with a diameter of 40 mm at 27.5 m/s), withstands wind and suction loads in accordance with IEC 61215, and comes with a 40-year weather resistance guarantee.
Makes dual use of space - as a functional canopy and for solar power generation. Reduces energy costs thanks to a high power density of 196 Wp/m² and an 80% output guarantee over 25 years.
The bifacial cell technology in the glass-glass module harnesses both direct and reflected light from the underside - for additional yield gains.
Certified for overhead use in accordance with IEC 61730 and SIA 2057, as well as high fire resistance (Class BRoof(t1) / VKF RF 2) and building approval as laminated safety glass (LSG) in accordance with DIN 18008 ensure the highest level of safety.
The frameless design of the glass-glass construction ensures excellent self-cleanability and minimal maintenance.
Combines high-quality glass architecture with modern photovoltaic technologies and blends seamlessly into carports, parking canopies, and patios.
Developed and manufactured in Switzerland using carbon-neutral electricity. Guarantees short transport routes and the highest quality standards.
The 3S overhead solar module is a glass-glass PV module specifically designed for overhead applications. It is suitable for various types of roofing, such as open structures, parking areas, or patios. The module combines weather protection with energy generation, thereby supporting the efficient multi-use of space. The robust glass-glass design and certified overhead suitability ensure high safety and durability while meeting demanding architectural requirements.

Overhead solutions refer to solar systems that serve both as a protective roof and as a power plant. 3S’s certified glass-glass solar modules are ideal for open structures, carports, parking lot canopies, pergolas, or patios. They enable efficient multi-use: They provide reliable weather and sun protection for vehicles or people while simultaneously generating CO₂-neutral electricity directly on the surface being used.
Safety is the top priority for overhead glazing. The 3S overhead module is a glass-glass module that has been specifically tested and approved for this purpose. It meets the strict Swiss building and safety standards for overhead construction, such as the tests in accordance with SIA 2057 as well as international standards IEC 61215 and IEC 61730. The module consists of a robust combination of tempered glass (TVG), which minimizes the risk of glass breakage and ensures maximum protection for people and vehicles below in the event of an emergency.
To guarantee investors and builders maximum planning certainty and value retention, 3S offers exceptionally long-term warranty commitments:
product guarantee: 10 years.
weather resistance guarantee: 40 years.
output guarantee: 1 year at 97% of minimum output, as well as a linear warranty of to 80% over 25 years the minimum output.
The 3S overhead module uses advanced, double-sided solar technology (bifacial cells). This means that the module not only captures direct sunlight from above, but also diffuse and reflected light from below (e.g., light reflected from light-colored asphalt, vehicles, or the patio floor). With excellent Bifaciality factor of approximately 80.8% (performance) the system generates significantly higher yields compared to conventional single-sided modules, which significantly shortens the payback period for investors.
