simplex roof

south orientated substructure
for flat and inclined roofs up to an anlge of 15°

schnelle Montage

fast mounting

entwickelt im Windkanal

developed in a wind tunnel

Ultraleicht und nahezu ballastierungsfrei

ultra lightweight with a minimum of ballast needed

A mounting system with little to no ballast required

Thanks to its aerodynamic design, simplex roof requires little to no added ballast. Even roofs with a limited load-bearing capacity can be fitted with this particularly light-weight mounting system for photovoltaic panels.

As the product can be set at an incline of up to 20°, it is possible to make use of the photovoltaic potential of surfaces on flat and gently inclined roofs with an angle of up to 15°.

Simple and roof-friendly mounting

A great advantage of the simplex roof is its unique ease of installation. The system is composed of a few individual parts, which are pre-mounted in the factory in such as way that the system can be mounted incredibly easily and in the shortest possible timespan.
The functional supporting rails make the installation of the system incomparably roof-friendly. The building protection mats, specially selected according to the type of roof, are pre-fitted and the system allows for water drainage in all directions.


“We´ve already installed numerous mounting systems being able to say that yours is the fastest and most comfortable one by far.”

– Ricardo Latzkow,
Head of project management, Polarys
