OWO System

The innovative flat roof system.

  • Lean and innovative design maximizes the use of the available surface: up ti 82% use of the roof space is possible
  • Easy and extremely fast to install: Only 5 components are needed, less than 15 minutes installation time for 1 kWp
  • Optimized load spreading of the modu- les: no part of the roof must withstand a high point load.
  • Optimized aerodynamic: in many situ- ations no additional ballast is needed. This reduces the overall loads that the roof is required to support.

The new OWO system provides the per- fect solution for maximum power output, by optimizing the use of the available space on your flat roof. Using the inno- vative pylon technology together with the appending fixing clamp it is possible to install two modules with just one screw. Thanks to our screw slot no slot nut is needed anymore. By using this technolo- gy the necessary time for installation and the use of material is vastly reduced. Based on wind tunnel analysis we opti- mized the geometry and aerodynamic

of the OWO system, therefore it has an intelligent air stream and is stressed by reduced wind loads. This means in many situations additional ballast can be avo- ided or at least reduced.
