Dutch firm launches mounting system for fragile roofs
A new photovoltaic mounting solution designed by Dutch startup Rable aims to facilitate solar installations on roofs with low load-bearing capacities.
Key points
- Rable4Roofs utilizes a self-supporting lattice framework made from galvanized steel.
- The technology decreases required anchor points by 95% compared to standard systems.
- The system distributes weight onto roof purlins, achieving loads between 6 kg/m² and 15 kg/m².
What happened
Dutch startup Rable has introduced a photovoltaic mounting framework titled Rable4Roofs, built to support solar panels on fragile structures and low-load buildings. According to pv magazine, the technology relies on a self-supporting lattice arrangement constructed from Belgian galvanized steel, which carries a 15-year corrosion warranty.
The structural design combines compression elements within the main framework with tension cables to form a rigid grid. Sales engineer Mevanly Karamoko explained to pv magazine that the weight is directed onto roof purlins instead of the panels themselves, achieving loads ranging from 6 kg/m² to 15 kg/m².
Why it matters
The configuration aims to address challenges associated with weak buildings and compressible insulation layers that typically fail to meet insurer requirements. By lowering the number of necessary anchor points by 95% relative to traditional setups, the technology can reduce capital expenditures and avoid expensive roof renovations.
What comes next
Having completed 60 projects in its initial 30 months, Rable is expanding its footprint across Europe. The company is currently executing installations in France, including a supermarket project in Châtenoy-en-Bresse, and seeks further technical approvals to support its market deployment.
