Solar solutions for : Installers & Roofers

The future of the solar roof is integrated - become part of it.

As an installer or roofing professional, you know that many customers today are looking for more than just a solar solution; they are looking for aesthetics and durability. With in-roof systems from 3S, you can offer your customers a solution that combines craftsmanship and design with state-of-the-art solar technology and performance. Benefit from systems that have been developed for efficient installation and secure a competitive advantage through quality and innovation "Made in Switzerland".

In-roof vs on-roof: Why integration is the better choice

While conventional rooftop systems often look out of place, our in-roof solar solutions redefine the building envelope. Instead of installing heavy constructions on an existing covering, the solar energy system itself becomes the protective skin of the house and an efficient energy source at the same time. Seamless integration into the building envelope creates an uncompromising aesthetic that beautifully enhances the architecture.

Benefit from the advantages of 3S solar systems

Carefree and quick installation

Only a few components are required to install the solar systems from 3S. The system is also optimized for one-person installation, as each module weighs less than 25 kg. This significantly speeds up construction progress.

Seamlessly integrated into the architecture

The 3S solar systems impress with their frameless modules, which enable a homogeneous appearance and complete surface coverage. The modules are also available in individual dimensions, different colors and satin-finished glass. This allows you to meet even the most demanding design requirements of your customers.

Robust solution from a single source

The solar systems from 3S are designed for extreme wind and snow loads and offer maximum hail resistance (HW5 in the solar roof). With a 40-year weather resistance guarantee and a 25-year output guarantee (80 %), you benefit from above-average longevity. For you, this means: minimum complaint rates, maximum customer satisfaction.

Compensation of construction tolerances & maximum yields

The floating installation of 3S solar systems makes it easy to compensate for construction tolerances on the substructure. The system remains flexible and stress cracks are effectively avoided. The frameless solar modules are self-cleaning and individually rear-ventilated. This enables maximum yields.

Short delivery routes & planning reliability

The 3S solar modules are manufactured in Switzerland. This reduces delivery times and minimizes the risk of transport damage. It gives you the security you need for your resource planning.

Investment protection

We offer you easy replacement of defective modules and high availability of spare parts. This guarantees your customers long-term investment protection.

Personal contact

At 3S, you benefit from competent advice from our experts and comprehensive know-how from development to installation. We speak your language and support you with technical challenges over the entire life of a solar energy system. If required, we can also support you on site at the construction site or in determining the condition of a system during operation.

It's good to know that we can produce and use a large proportion of our energy ourselves.

Frequently asked questions

  • What advantages does BIPV offer compared to conventional PV systems?

    BIPV offers several advantages:

    • Aesthetics: By integrating BIPV into the building envelope, it blends harmoniously into the architectural design.

    • Space saving: As BIPV modules replace conventional building materials, additional space is saved on the roof or facade.

    • Double function: BIPV modules provide both protection from the weather effects and energy generation.

    • Sustainability: BIPV helps to reduce the ecological footprint of a building by using renewable energy.

  • How does the installation of BIPV modules differ from conventional PV systems?

    The installation of BIPV modules requires careful planning and collaboration between architects, civil engineers and PV specialists. As BIPV modules are an integral part of the building envelope, they must meet both the aesthetic and functional requirements of the building. This includes consideration of tightness, thermal insulation and structural integrity.

  • What needs to be considered when planning a BIPV project?

    The following points should be taken into account when planning a BIPV project:

    • Architectural integration: The modules must aesthetically match the design of the building.

    • Technical specifications: Selection of the right modules based on efficiency, performance and local climatic conditions.

    • Regulatory requirements: Compliance with local building regulations and standards.

    • Economic efficiency: Cost-benefit analysis and consideration of funding opportunities.

    • Cooperation: Close cooperation between architects, civil engineers and PV specialists to ensure optimum integration.
