Mounting Systems FD3 front module carrier

The Mounting Systems FD3 module support (front) is a central component of the FD3 flat roof system. This system is specially designed for ballast-optimised installation of photovoltaic systems on flat roofs with low load reserves. The front module support forms the low fixed point of the substructure and largely determines the angle of inclination of the solar modules.

Made from high-quality, corrosion-resistant aluminium, the module support ensures a durable and secure connection between the floor rail and the front edge of the solar module. The aerodynamic design of the FD3 system minimises wind lift, significantly reducing the need for heavy ballast.

Highlights at a glance

• Optimised aerodynamics: Part of the overall FD3 system, which has been tested in a wind tunnel to ensure maximum stability with minimum counterweight.
• High material quality: Made of weather-resistant aluminium, ensuring a long service life without corrosion risk.
• Quick assembly: Thanks to pre-assembled components and simple screw connections, the front support can quickly be fixed to the floor rails.
• Precise inclination: In combination with the rear module support, a fixed installation angle (mainly 10° or 15°) is achieved for optimal yield.
• Protection of the roof covering: The system is installed without roof penetration; the module support distributes the loads evenly across the floor rails.
• Module-friendly fixation: The contact surfaces are designed so that the frames of the solar modules are securely held without causing mechanical stress.

Areas of application

The FD3 module support front is the basic component for flat roof installations:

• Commercial flat roofs
  • Ideal for large industrial halls with trapezoidal sheet metal or foil sealing, where the total weight of the system matters.
• Private houses with flat roofs
  • Simple and visually discreet elevation for garages, carports or bungalows.
• East-west or south orientation
  • The module support can be flexibly used in various FD3 configurations, both for classical south-facing systems and roof area-optimised east-west systems.

Installation & safety instructions

• System network
  • The front module support may only be used in combination with the original FD3 floor rails and the corresponding connectors to avoid jeopardising the structural approval.
• Ballasting
  • Ensure that the ballast required according to the structural plan (e.g., concrete blocks) is correctly placed on the rails, as the module support itself weighs nothing.
• Maintain distances
  • Ensure correct row distances during installation to prevent mutual shading of the modules.

Properties

FAQs on the FD3 module support front

Can I adjust the angle of inclination flexibly?

No.

• With the FD3 system, the inclination angle is determined by the fixed heights of the front and rear module supports (10° as standard). This provides high stability and easy wind load planning.

Is the mounting material for fixing to the module included?

Usually separate.

• The module support is attached to the floor rail. For securing the solar modules to the support, the appropriate centre and end clamps are required, which are matched to the frame height of your modules.

Do I need protective mats?

Yes, strongly recommended.

• To protect the roof membrane or bitumen sheet from mechanical damage by the floor rails, suitable protective mats (PADs) should always be placed under the system's contact points.

How many front supports do I need?

One support per module support point.

• Usually each module requires two support points at the front. Depending on the rail layout, one FD3 module support front is mounted per support point.
