This product is a rear wind deflector designed to optimise the aerodynamics of a flat-roof photovoltaic structure fitted with the FlatFix Fusion system. This device secures the installation by enclosing the rear of the modules, thereby reducing wind resistance and uplift forces to ensure the overall stability of the system.

IMPORTANT: It is essential to select the correct model based on the dimensions of your panels and to provide one wind deflector per panel.

This deflector clips directly onto the Fusion structure, ensuring a clean finish and long-lasting protection against the elements. The product is available in four models to fit the length of your modules perfectly:

  • Model 1600: For panels from 1500 to 1690 mm
  • Model 1700: For panels from 1580 to 1800 mm
  • Model 1900: For panels from 1800 to 1990 mm
  • Model 2000: For panels from 1990 to 2190 mm

Technical specifications

  • Compatible system: FlatFix Fusion (flat roofs only)
  • Function: Aerodynamic protection and reduction of lift force
  • Installation: One deflector per panel (1:1)
  • Material: High corrosion-resistant steel

FlatFix Fusion Rear Wind Deflector: aerodynamic protection for flat roofs

Déflecteur de vent arrière FlatFix Fusion pour panneau solaire


The FlatFix Fusion rear wind deflector is a crucial component for securing photovoltaic installations on flat roofs. Its role is to shield the rear of the modules to prevent wind from rushing under the structure. This aerodynamic optimisation significantly reduces lift forces, thereby protecting the roof’s waterproofing and the integrity of your panels.

This product is made from high-quality steel to provide long-lasting resistance to weathering and corrosion. It allows for a lighter installation by reducing the need for heavy ballast in exposed areas.





Why install FlatFix Fusion rear deflectors?

  • Certified stability: creates a ground-hugging effect during strong gusts of wind.
  • Structural protection: reduces vibrations and mechanical stress on the FlatFix Fusion system’s fixings.
  • Quick installation: clicks directly onto the rear structure without drilling, maintaining the system’s characteristic speed of installation.





Model selection and panel compatibility

Important note: to ensure the safety of your installation, always provide one rear wind deflector per solar panel. It is essential to choose the model suited to the length of your modules:

  • Model 1600 (range from 1500 to 1690 mm): specifically designed for compact panels such as the JNL 280/300 series, Hanover 320, or the Hyundai 345.
  • Model 1700 (range from 1580 to 1800 mm): the standard for residential modules such as the HT-SAAE Jupiter 450Wp, Leapton 450Wp, Aiko and others....
  • Model 1900 (range from 1800 to 1990 mm): suitable for new wide-format panels such as Luxen 500Wc, Leapton 500Wc and Jolywood 500Wc.
  • Model 2000 (range from 1990 to 2190 mm): designed for very large-format industrial modules.





Technical specifications

  • Compatible system: FlatFix Fusion (flat roof).
  • Material: high-strength steel.
  • Configuration: 1 unit per solar panel (1:1 ratio).
  • EAN reference: 0712971129689





FAQ - FlatFix Fusion rear wind deflector

1. What is the main purpose of the rear deflector? +
The rear deflector acts as an aerodynamic shield. It closes the space at the rear of the tilted panels to prevent wind from rushing underneath. This creates a ground-hugging effect and significantly reduces the risk of your panels being lifted or displaced during severe storms.
2. Is it mandatory to install one per panel? +
Yes, to ensure the certified stability of the FlatFix Fusion system, it is essential to maintain a ratio of one deflector per solar panel. Failure to use deflectors would compromise the aerodynamics of the system and could result in structural damage not covered by the warranty.
3. How do I know which size to choose (1600, 1700, 1900 or 2000)? +
The size of the deflector must match the length of your solar panel.
  • The 1700 is the standard size for standard residential panels (around 1.75m).
  • The 1900 and 2000 are designed for wide panels (500Wp and above).
Always check the technical specifications of your modules to select the compatible model.
4. Does the installation require drilling into the roof? +
Not at all. Like the entire FlatFix Fusion system, the deflector is installed without any drilling into the roof waterproofing. It is secured by clipping and screwing directly onto the metal support structure, ensuring a quick, clean and secure installation.
