Mounting system PLUS

Our mounting system PLUS stands for safety, stability and longevity. The system largely consists of aluminum and is made up of just a few components. All components are geared to each other, therefor allowing for a quick and reliable installation. The system implements an equal weight distribution throughout the collector frame and a balanced load on the roof structure. Irrespective of the roof angle and the geographical region, the system offers an ideal solution for every solar thermal system.

As part of a building, solar thermal systems are subject to building regulations. Applicable building regulations are:

  • EN 1991 - Actions on structures
  • EN 1990 - Basis of structural design
  • VDI 6012 page 1.4 – Mounting solar modules and solar collectors on buildings or structures

These regulations address, planning, preparation and development of mounting systems for solar thermal systems.

As a result the mounting system must lead the occurring forces secure to the roof structure without any damage at any time. To reduce the risk of damage and liability it is necessary to establish a mounting system that meets all these requirements.

The on-roof mounting system is also available with a slope correction (15°, 25°). Using the slope correction on slightly tilted roofs leads to a higher solar yield for systems with heating support.

Angles for flat roof mounting systems are adjustable to 30°, 45°or 55° and for wall installations to 45°or 60°.


Technical advantages

  • single-layered mounting system
  • quick installation
  • high stability
  • high longevity
  • proven quality
  • rafter independent
  • no losable parts
  • collector specific preassembled sets

Adjustable & high stability

  • Roof hooks consists of a support bracket, base plate and cantilever beam
  • the additional support bracket provides for more stability and leads to remarkable higher load reserves
  • The multi-head connector compensates even significant unevenness of the roof. A “clicking” noise indicates that the profile is securely attached to the multi-head connector
  • Profiles are made of high-grade aluminum alloy with a large hollow chamber, which minimizes weight and provides exceptional load capacity.
  • Hanger bolts with special thread geometry are excellently suited for mounting on trapezoidal or corrugated roofs. The innovative gasket locks into place by simply pushing it down
  • A special clay tile roof connection kit reduces the installation time and avoids damage to the clay tiles.
  • The mounting systems PLUS is designed to fit all Ritter evacuated tube collectors. It is also possible to adapt it for flat plate collectors
