Installation without roof penetration


Using the Light-EW mounting system for photovoltaic systems, you can install the PV modules in an east-west direction without roof penetration. The abbreviation EW stands for East-West and indicates the orientation of the roof. The system is available with inclination angles of 10° and 15° for a high energy yield or maximum total output. The flexible arrangement of the modules in landscape mounting ensures an even load distribution on the roof surface. In order to guarantee a minimum additional roof load, we have tested and optimised the mounting system in a wind tunnel. Due to the current Light-EW design, you can use the same components of the 10° and 15° variants by simply rotating the front basis and upper part of the centre support.

+ Clickstone internal click technology

By using the well-proven Clickstone Technology of Mounting Systems for module clamping, we can ensure a simple and fast installation.

+ Long lifespan

All components of the Light-EW mounting system are made of aluminium and V2A stainless steel. Both materials are ideal for outdoor use as they have a high corrosion resistance. This guarantees a maximum lifespan. In addition, both materials are completely recyclable and environmentally friendly.
