SOLon FR for membrane roofs
SOLon FR – vertical PV for membrane roofs
SOLon FR is a vertical photovoltaic system for membrane roofs. The bifacial modules are mounted vertically and generate solar power via the front and rear sides. Installation is carried out without roof penetration and is checked on a project-specific basis for roof structure, structural analysis and compatibility with the roof membrane.
Membrane roofs place special demands on PV systems. Roof membrane, material, age, structure and manufacturer approvals must be carefully taken into account. For this reason, SOLon FR is planned on a project-specific basis and tailored to the respective roof waterproofing.
The EPDM foot system supports gentle placement on sensitive roof membranes. At the same time, the roof waterproofing remains untouched, as SOLon FR is installed without roof penetration.
For membrane roofs
Vertical PV for membrane and flat roofs.
Lightweight system
Low surface load for structurally sensitive flat roofs.
EPDM foot system
Roof-friendly EPDM foot for sensitive membranes.
Vertical yield
East-west generation with strong spring/autumn output.
No roof penetration
Installation without penetrating the waterproofing.
Planning support
Support with design, structural analysis and roof checks.
Full-surface EPDM base for secure installation on membrane roofs – without roof penetration
Roof-friendly EPDM foot
SOLon FR makes membrane roofs usable for vertical photovoltaics. The EPDM-based mounting foot rests fully and gently on the roof membrane, stabilising the system without roof penetration and supporting safe, project-specific planning.
