SOLAR GREEN ROOF SOLAR WRB
The SOLAR GREEN ROOF WRB is a load-bearing solar mounting system for the roof-penetration-free mounting of PV modules or PV module rows.
The versatile substructure makes it possible to mount almost all standard solar modules with inclinations of 10°, 15° or 20°.
The module rows can be installed in a south or east-west orientation. The modules can be mounted both vertically (portrait) and horizontally (landscape).
The RETENTION ROOF FLOW CONTROL is an economical and efficient product for retaining rainwater and delaying runoff. In combination with the solar elevation, multifunctional roof use is possible.
The use of the proven water retention box WRB 80F helps to maintain the natural water balance by increasing evaporation and minimizing surface runoff.
