TopSon F3-1 and TopSon F3-1Q High performance flat-plate collectors

The new solar rooftop installation sets.

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

WOLF mounting system with general building authority approval (DIBt)

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

WOLF universal sets:

  • suitable for most applications
  • simple checking of the application limits with the help of the WOLF price list
  • adaption of the mounting system to individual requirements with extensive accessories
