EFFICIENT. UNCOMPLICATED. UNIVERSAL.

The COMPACTFLAT GS system is a highly elevated flat roof system specifically developed for mounting on green roofs and for applications with bifacial modules. This mounting solution achieves performance enhancing effects of the PV modules and provides the necessary distance to green roof surfaces.

For bifacial PV modules.

Bifacial modules are replacing more and more traditional foil modules and differ only slightly in terms of cost. Many module manufacturers are switching completely to bifacial modules. The COMPACTFLAT GS was specially developed for flat roof applications in combination with
bifacial modules. Independent laboratory tests have shown that by reflecting light from a light roof surface, yield increases of up to 20 %* can be achieved.

For green roofs

Flat roofs are widely vegetated, but traditional flat roof systems have limited suitability for green roof applications. The plant cover requires light and care. This can only be ensured with a highly elevated system with good accessibility.

Ideal for green roof applications
High stability at moderate costs
Fast assembly
Based on the proven bracket system
Up to 20 % higher yield with bifacial modules
Few components, no long rails

Ballast trays

This system variant with ballast trays, available in various sizes, is mainly used in areas with high wind loads and roofs with low point loads. The main advantages of this installation variant are, on the one hand, the additional ballast that can be installed per module and, on the other hand, the even distribution of the concentrated load on the roofing. The ballast tray can also be used for ballasting on gravel roofs by putting the gravel into the ballast trays.

Roof anchor

AEROCOMPACT offers a sophisticated hybrid solution for roofs that cannot withstand the extra weight of a photovoltaic system. The combination of roof attachment points and ballast reduces the overall weight of the installation. This option can also be used in areas with seismic activity to prevent the system from shifting due to the effect of earthquakes.

Additional protection pads

To prevent damage to the roof membrane, additional protection pads can be placed under the ballast and the brackets. The protection pad consists of felt material and an adhesive strip for easy fastening.

Solid ballasting bodies, such as paving stones, can be placed on the brackets without any fasteners. Our 3D engineering software AEROTOOL can be used to calculate exactly how much weight needs to be placed on each bracket.

Depending on the project location, ballast trays are required in order to be able to install additional ballasts required per PV module, as well as to reduce point loads.

In addition to ballasting with ballast bodies, the system can be screwed into various substrates with our roof and ground screws, without the use of large machinery, to withstand high wind loads.
