LEVEL roof-integrated system

The solar system for sophisticated roof surfaces.


The popular roof-integrated system enables complete roof covering and brings out the maximum solar yield even from complex surfaces. Individual solar modules (edge modules, integration of skylights, snow guard, individual anchoring points, etc.) as well as offset module grids ("English" layout) are part of the concept.


Areas of application


LEVEL is used for pitched roofs, challenging roof geometries, individual roof integrations, as well as façades.

The LEVEL roof-integrated system in the classic application for complex roof surfaces.

The LEVEL facade can be assembled in the same way without additional components.

Installation steps

How it works

The holding hooks are screwed onto the roof battens. The sealing rails are fitted onto them. The solar modules are laid in. Later dismantling is possible without restrictions.

1 Roof battens 80 x 40 and 50 x 50 are fitted alternately in the grid.

2 The rail hooks are mounted directly on the roof battens.

3 The support rails can be pushed easily into the rail hooks.

4 Central hooks provide additional stability.

5 The solar modules can be pushed up from below and laid in.

6 The solar tile system allows individual layouts.

Optional: Snow guard

Option: Skylight

Optional: Anchoring devices for personnel safety


The LEVEL roof-integrated system can easily be combined with all standard roof coverings such as roof tiles, shingles or aluminium composite panels. A skylight (Wenger Fenster) specially developed for the LEVEL roof-integrated system enables seamless integration. LEVEL can be equipped with an integrated snow guard.

Type of installation

The system is laid overlapping, using the conventional or English method (horizontal offset).

Installation time

10 m2 / man-hour (experienced installation personnel)

Solar modules

Basic modules

Half and quarter modules with identical appearance are among the standard components of the system.

6x10 cells

4x10 cells

6x4 cells

4x4 cells

Colour variations

The basic palette contains three colour versions. More complex design requirements (colour, surface) can be realised with individually designed solar modules.

Sub-roof requirements

  • Roof pitch above 25°: sub-roof for normal demands
  • 14° - 25°: sub-roof for increased demands
  • 6° - 13°: sub-roof for extraordinary demands
  • 0° - 5°: sub-roof with flat roof quality
