Solar Green Roof
Solarbase - 15°

Characteristics

  • Cost effective combination of green roofs and photovoltaics
  • Ballasted and penetration-free system
  • Higher mounting of the photovoltaic panels to avoid shading
  • Vegetation possible beneath the support units
  • Low maintenance requirement
  • Wind tunnel tested
  • Increased output of the photovoltaic system
  • South or East-West orientation possible
  • Inverted roof: generally suitable; however individual consulting is necessary

*Depending on the load capacity of the substructure, Optigreen "High Density (HD)" or "Low Density (LD)" substrates can be used. Weight specifications refer to saturated conditions; dry weight is approximately 60 - 70 % of the saturated weight. Wind up-lift protection has to be taken into account.
**Determined at 0° according to FLL guidelines.
