Flat roof system

Ballasted

Install your photovoltaic modules on flat roofs without penetrating the roof membrane, thanks to ballasted mounting systems designed for quick installation, high safety, and protection of the roof membrane.

These solutions are available in various configurations and can be adapted to different on-site requirements:
Configurations in East-West or South orientation,
lightweight and pre-assembled structures,
as well as systems with optimized aerodynamics for significant reduction of ballast requirements.

Designed for low-pitch roofs (≤ 5°), these systems are compatible with most roof structures and allow for quick installation while reducing the structural load on the building.

  • Quick and easy assembly

    Pre-assembled components and intelligent connection systems allow for rapid installation on the construction site and significantly reduce assembly effort.

  • Optimized ballast and reduced roof load

    Thanks to an aerodynamically optimized design, the ballast requirement is significantly reduced, thereby minimizing the load on the roof structure.

  • Flexibility for different projects

    Ballasted Mounting System for Flat Roofs – East-West Orientation

    Different configurations (East-West or South) as well as modular systems allow for adaptation to various roof types and project requirements.

The east-west orientation allows for optimal use of the available roof space while simultaneously providing high stability against wind loads.

Suitable for projects requiring quick implementation and reduced roof load.

FD3

FD3

Ballasted Mounting System for Flat Roofs – South or East-West Orientation

FD3 Premium Line is a photovoltaic mounting system for flat roofs that offers an optimal balance between performance, fast installation, and reduced ballast.

The aerodynamically optimized design allows for a significant reduction in ballast requirements, thereby reducing the load on the roof structure. The simplified mounting system with quick-connectors facilitates on-site installation.

Suitable for different configurations and projects requiring flexibility, efficiency, and robustness.

  • FD3 – S

    FD3-S Premium Line is a photovoltaic mounting system for south-facing flat roofs that ensures optimized energy generation and high stability.

    The system is compatible with most roof membranes and allows for quick installation without penetrating the roof surface. Thanks to its robust construction and available tilt angles (10° or 15°), it is ideally suited for projects with high demands on performance and reliability.

  • FD3 – EW

    Ballasted Mounting System for Flat Roofs – East-West Orientation

    FD3-EW Premium Line is a photovoltaic mounting system for flat roofs with an East-West orientation, enabling optimal use of roof space and efficient energy generation.

    The ballasted system allows for quick installation without penetrating the roof membrane and offers high stability against weather influences. The robust construction and the 10° tilt make it a suitable solution for performance-oriented projects.

  • FD3 – SolarFix

    Hybrid Mounting System for Flat Roofs – Ballasted or Anchored

    FD3 Premium Line – SolarFix is a photovoltaic mounting system for flat roofs that allows for installation with or without ballast enabled by direct anchoring to the building structure.

    The system offers high flexibility and allows for Reduction or complete elimination of ballast, thereby minimizing the roof load. It is compatible with various substrates (concrete, trapezoidal sheeting, wood, etc.) and is suitable for numerous project requirements.

FAQ

Your questions about the takeover

  • Will LightX and FD3 remain available?

    Product continuity is the top priority. LightX and FD3 will remain fully available—now backed by the industrial capacity and supply chain of Dome Solar, ensuring reliable product availability at any scale.

  • Does „Made in Germany“ still count?

    Yes. The original German suppliers will be retained. Engineering standards, requirements for structural calculations, and quality controls will remain unchanged. The German manufacturing tradition is a central part of Mounting Systems' brand identity.

  • Who can I contact for technical support?

    Your existing contacts remain unchanged. Dome Solar is strengthening local technical teams in key markets—Spain, Poland, Germany, Morocco, and beyond—to ensure strong support for EPCs and installers during the transition phase and beyond.

  • What new products are available now?

    With Dome Solar, you now have access to an expanded portfolio, including pitched roof systems (NPA, TOP, SIDE, Helios B2, Ital Solar, Fibro), RC3 carport solutions, and ground-mounted systems.
