Our FixGrid 18 flat roof system with a 10 degree angle of inclination will be now available. This saves ballasting without reducing the modules’ self-cleaning ability.
Most manufacturers guarantee a photo-voltaic module’s self-cleaning ability for an inclination over 10 degrees. This comes into effect at a 13 degree angle of inclination for our standard FixGrid model.
It is also true that: the smaller the angle of inclination, the less ballasting is required. Ballasting is not only a cost factor. Flat roofs also often have limited load-bearing reserves. They can only be used for photo-voltaic installations with loads that are as small as possible.
Our new version of the FixGrid 18 brings both together under one roof: A flat roofing system, which is ballast optimised, yet also guarantees the module’s self-cleaning ability. With a 10 degree angle of inclination, it requires less ballasting than the standard 13 degree version. We have already taken the system into account in our design tool, the Schletter Configurator.
