The new solar rooftop installation kit

WOLF presents an optimised range of solar rooftop installation sets for TopSon F3-1 / F3-1Q and CFK-1 flat solar collectors. The mounting system is not only quick and easy to install, it also dependably withstands extremely heavy wind and snow loads.

 

WOLF assembly system with general building authority approval (DIBt):

  • Safety for end users and skilled tradesmen through a statically calculated system approved by the DIBt (German Institute for Construction Technology) (approval number: Z-14.4-797)
  • Complies with building regulations
  • No load transfer via the tiles
  • Quick and simple installation
  • Flexibly adaptable to any roof design
  • Weather-resistant materials
  • Extremely stable and resilient even to heavy snow and wind loads

 

Because no two roofs are the same: perfect for custom configurations - the WOLF online solar configurator

  • Individual planning and site-specific design of the installation system
  • Optimum composition of the required components
  • Save and download solar system plans quickly and easily
  • Export as a PDF report with QR code for quick editing
  • Proposal of the snow and wind load zone based on the indicated location
