The KDP-BIFACIAL-BK-WZ structure is a design suitable for a flat roof. The system allows modules to be mounted horizontally and can be ballasted or intrusive. The structure allows the installation of bifacial photovoltaic panels. The advantage of the design is that modules can be mounted without clamps, which significantly speeds up the work. To ensure adequate protection against corrosion, the KDP-BIFACIAL-BK-WZ ground-mounted photovoltaic structure is made of black S320 steel with Magnelis® metallic coating.
