Flat Roof PV Mounting Systems
Terrasol mounting systems for flat roofs and concrete slabs. Screwed or ballasted fixing, S320GD steel, tilt angles 5°–35° for maximum output on every roof.
Flat roof PV mounting systems by Axinar Terrasol are designed exclusively for installations on flat roofs and concrete slabs. With a choice of screwed or ballasted (weighted) fixing, they cover every requirement — from industrial buildings to apartment blocks.
Choosing an Axinar flat roof PV mounting system, you get safe installation without risk to waterproofing, an optimal tilt angle for maximum energy yield, and a modular design for fast assembly. Every rooftop solar mounting system includes a free structural analysis per Eurocodes.
Beyond flat roof PV mounting systems, Axinar also manufactures mounting structures for ground-mount solar parks, solar carports and pitched roofs.
Flat Roof PV Mounting — Fixing Options
Method selection for flat roof PV mounting is based on the roof characteristics and project requirements.
Screwed to Concrete
Flat roof PV mounting systems with screwed fixing provide maximum stability and safety for permanent installations. Suitable for buildings that allow penetration, with top resistance to wind and seismic loads.
Ballasted Fixing
Completely non-invasive flat roof mounting — no penetration required. Ideal for rented or protected rooftops, with weight adjusted to local wind conditions.
Systems suitable for flat roofs with or without penetration capability.
Adjustable tilt angles for maximum energy yield.
Fixing options for every project requirement (screwed or ballast).
Modular design for easy and fast installation.

Flat Roof Mount Advantages
Waterproofing
Flat roof PV mounting with the ballasted method requires no penetration, preserving full waterproofing. The screwed method uses special waterproofing gaskets at all penetration points.
East-West
Dual panel orientation (East–West) ensures uniform energy production throughout the day and maximises the use of available roof area.
Wind Load
Design follows Eurocodes for wind load (EN 1991-1-4). The ballasted method adjusts weight to local wind conditions.
Modular
Modular design enables fast installation and easy expansion. Fewer components, less labour time, lower cost.
