45° support structure for 4 photovoltaic modules on the roof
3mm anodized aluminium structure to mount 4 solar panels side by side (max combined width 420cm) at a fixed 45° tilt. Suitable for flat roofs with ground ballast anchoring or vertical wall mounting.
Planning a row of modules on a flat roof or wall? This 45° structure combines rails, triangular supports and clamps in one coordinated system, avoiding improvised component pairings.
Before ordering, compare the total width and frame thickness. Anchors or ballast must be sized for the substrate, wind and snow loads by a qualified technician.
This 45° support structure in 3mm anodized aluminium is designed to mount 4 solar panels side by side (maximum combined width 420 cm) on a flat roof or via vertical wall mounting, canopy-style. The fixed 45° tilt guarantees good energy yield even without an optimally oriented roof.
What this structure is for
The system is ballasted directly on a flat roof, avoiding the need to drill through the waterproofing membrane, or it can be fixed directly to a vertical wall, for example to create a small solar canopy. Three triangular trestles hold the row of panels at a fixed 45° tilt, adding an extra intermediate support point given the longer length of the structure, while the central clamps join the four side-by-side modules into one stable plane.

Frequently asked questions
What's the maximum combined width of the 4 panels supported?
The structure is sized for 4 side-by-side solar panels with a combined width of up to 420 cm. For wider panels, please contact us to check compatibility.
Why does this structure have 3 trestles instead of 2?
With a row of 4 panels, the structure is longer: the third, central trestle provides an intermediate support point that prevents the rails from flexing and ensures greater stability along the full length.
Can I install it on a flat roof without drilling the membrane?
Yes, the structure is designed for ground ballast anchoring, avoiding any drilling into the roof's waterproofing membrane. Alternatively, it can be fixed vertically to a wall.
What's included in the package?
The kit includes 3 triangular trestles at 45°, 4 horizontal cross rails (440cm) with 2 connecting joints, 4 end fixing clamps, 6 central fixing clamps and complete mounting hardware. Ground ballasts are not included.
What are the rail connecting joints for?
The 2 joints connect the 440cm cross rails into one continuous beam, needed to span the full width of the 4 side-by-side panels while keeping the structure rigid and aligned.
