Flat roof | east-west-system I (double-layer) « the rock »
Our solution for east-west direction
- Maximum roof surface utlisation and evenly distibuted electricity production
- Optimum elevation angle 13° for good efficieny and self-cleaning
- Cross connections at module field edges for high stability
- High flexibility thanks to individually selectable row distance
- Connected module fields up 34 m length possible
Your benefits
Wind-tunnel tested aerodynamics
Wide and continuous base trough for good load redistribution to prevent damage on the roof insulation
Stability and flexibility thanks to cross layer system and module clamping in the optimum clamping range
Suitable for wide modules

More information about the flat roof mounting system
With our east-west II mounting system, you can optimise the use of the surface area of your flat roof: Compared to southfacing elevations, you can install nearly twice the module surface area. Electricity production is thus distributed more evenly throughout the entire day. The east-west II mounting system is a very secure and stable system for flat roofs with a pitch of up to 5° – and, what is more, it is quick and easy to assemble. The mounting system is fixed on the roof with its own weight and, if necessary, ballast stones, although the optimised aerodynamics of our system require little to no ballasting: an advantage for flat roofs with low load reserves. The mounting system consists of only a few components.
The substructure is installed in a modular grid. The base foot and the module support are clicked together, and the module fastened by the short side of the frame. The base trough, which can be used as a cable channel, has rounded edges and a separation layer to protect the roof membrane. The system is installed on foil and bitumen roofs and can also be installed on gravel roofs. Our various supports allow us to tailor solutions to the specific loads – even with heavy load requirements. Per default, we can subject the east-west II mounting system to loads of 2.4 kN/ m², and with a module clamp on the long side, even up to 4.8 kN/m².
