For roofs equipped with Evalon® membrane, our systems can be used on slopes of up to 37%.
Ballasted
-
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.
Fastening systems for flat roofs
Roof-Solar Bitumen
-
Roof-Solar Tilted Bitumen
Roof-Solar Tilted Bitumen is a photovoltaic mounting system designed for the installation of solar panels on flat roofs. It is particularly suited for buildings with bituminous waterproofing and enables fast installation without ballast or membrane perforation.
The use of 60 cm rails ensures linear (rather than point) load distribution, reducing the risk of damage to the waterproofing membrane.
-
Flat Roof Solar Bitumen
Roof-Solar Bitumen is a photovoltaic mounting system designed for the installation of solar panels on flat roofs with bituminous waterproofing. It is particularly suited for buildings equipped with this type of membrane and enables fast installation without ballast or membrane perforation, while preserving the integrity of the building.
The use of 60 cm rails ensures linear (rather than point) load distribution, reducing the risk of damage to the waterproofing membrane.
Roof-Solar PVC
-
Roof-Solar PVC Tilted
Roof-Solar PVC Tilted is a photovoltaic mounting system designed for the installation of solar panels on flat roofs. It is specifically suited for buildings with synthetic PVC waterproofing membranes and enables fast installation without ballast or membrane perforation.
The use of 60 cm rails ensures linear (rather than point) load distribution, reducing the risk of damage to the waterproofing membrane.
-
Roof-Solar PVC Flat
Roof-Solar PVC is a photovoltaic mounting system for the installation of solar modules on flat roofs. It is specifically designed for buildings with a synthetic PVC roofing membrane. The installation of photovoltaic modules is simplified without ballasting or penetration of the roofing membrane.
The use of 60 cm long Roof-Solar PVC rails allows for a linear (and not punctual) load distribution, thereby reducing the risk of puncturing.
Roof-Solar TPO
-
Roof-Solar TPO Sloped
Roof-Solar TPO Tilted is a photovoltaic mounting system designed for the installation of solar panels on flat roofs. It is specifically suited for buildings equipped with a TPO waterproofing membrane and enables fast installation without ballast or membrane perforation.
The use of 60 cm rails ensures linear (rather than point) load distribution, reducing the risk of damage to the waterproofing membrane.
-
Roof-Solar TPO Flat
Roof-Solar TPO is a photovoltaic fixing solution dedicated to flat roofs with TPO waterproofing membranes. Designed to integrate seamlessly with this type of roofing, it enables a simple and fast installation of modules without ballast or membrane perforation.
Its design ensures even load distribution through the use of 60 cm rails, limiting point loads and reducing the risk of damage to the waterproofing membrane.
Roof-Solar Evalon®
-
Roof-Solar Evalon® Tilted
Roof-Solar Evalon® Tilted is a photovoltaic mounting system designed for the installation of solar panels on flat roofs. It is specifically suited for buildings equipped with an Evalon® synthetic waterproofing membrane and enables fast installation without ballast or membrane perforation.
The use of 60 cm rails ensures linear (rather than point) load distribution, thereby limiting stress on the waterproofing.
-
Evalon® Flat Roof-Solar
Roof-Solar Evalon® is a photovoltaic fixing system designed for the installation of solar panels on flat roofs equipped with a synthetic Evalon® waterproofing membrane. It is particularly suited to this type of roofing and enables fast installation without ballast or membrane perforation, while preserving the integrity of the building.
The use of 60 cm rails ensures linear (rather than point) load distribution, thereby limiting stress on the waterproofing.

Fastenings for ballasted flat roofs
LightX
FD3
-
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.
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?
Thanks to Dome Solar, you now have access to an expanded portfolio, including systems for pitched roofs (NPA+ Side, NPA+ Top, NPO+, RB-Solar Tilt, Hélios B², Ital-Solar, Fibro-Solar), systems for flat roofs (Roof-Solar), a solution for carports (Hélios RC3), as well as systems for ground-mounted installations.
