OVERVIEW
Optigrün Solar FKD combines a photovoltaic mounting system with an extensive green roof build-up. It is designed to distribute stored water beneath the array while supporting standard photovoltaic module layouts.
The system does not require mechanical penetrations through the waterproofing membrane.
HOW IT WORKS
A load-supported base plate and mounting frame sit within the Solar FKD roof build-up. The drainage and water-storage board, substrate and vegetation provide the support and ballast required for the photovoltaic array.
