The AluLight TF has a fixed stand angle of twelve degrees and can be fastened to flat roofs while imposing little extra loading. Concrete curbstones weigh the system down and connect the individual frameworks to each other.
The pressure loading by the curbstones is distributed over most of the roof area. The modules can be fastened to the framework with normal module clamps. The system is compatible with all First Solar thin film modules and other modules of the same size.
