We’re building something special – but we need your advice. So we'd like to invite you to share your thoughts with us. We have just one question for you to answer – and, this month, it’s about our rooftop systems.

Schletter exists to make installing solar easier, safer, and more efficient than ever.

Our new ProLine series meets tomorrow’s standards today by using less material, offering higher load-bearing capacities, simplifying planning, improving on-site handling, and reducing the time you spend on roofs. Available in black or natural grey, ProLine represents the new generation of solar mounting systems for residential and industrial roofs.



Our infinitely adaptable solution for your sheet metal roof:

  • Enables almost any arrangement with just a few core components
  • Features click-in technology to make installations faster, easier, and safer
  • Is engineered for optimal load transfers with premium-grade aluminum
  • Provides strong, year-round support for your modules
  • Reduces time on the roof and related labor costs



  • Improved adjustability, stability and weight
  • Higher load capacity due to new geometries
  • Fast and flexible mounting by simple click-in
  • Quick mounting adapter comes pre-assembled
  • No pressure on the roof tile
  • Adjustable height up to 30 mm with Rapid roof hooks
  • Compatible with Schletter's Classic and ProLine rails



  • Aluminum EN AW-6063 T66
  • Reduced material with improved stability
  • Optimized geometric basis
  • Module bearing rails available in various lengths: 2450 mm, 3550 mm, 4750 mm, 5900 mm
  • Module bearing rails available in three different construction heights: 35 mm for smaller spans, 50 mm for medium spans and 70 mm for large spans



  • One size fits all: One middle and end clamp fits mounting module frames between 30 - 47 mm
  • Designed for all ProLine module-bearing rails
  • Claws can be rotated and are therefore suitable for both vertical and horizontal (linear) module clamping
  • Pre-assembled for quick installation
  • Built-in grounding function with integrated grounding pin

Want to get closer?

We've installed ProLine in the House of Schletter, our new metaverse experience.

Inside, you can interact with life-like, digital replicas of some of our most popular products, and learn all you need to know about them in a way that’s far more immersive than any manual or handbook.

It’s free to enter, and the doors are open.



Which advantages does ProLine have towards Schletter’s Classic system?

When developing the ProLine, we focused on saving weight and simplification - from planning and stock-keeping all the way to assembly on the construction site. For example, the ProLine mounting rails are lighter but also more resilient thanks to their improved geometry. The aluminum roof hooks are now fastened with a single screw. And with the module clamps, you will only have to decide on one colour in the future: black or silver. Finally, there are no longer different-sized clamps, just one end clamp and one middle clamp for all modules.

How can distributors, installers, and users prepare for the changeover?

During product development, we made sure there would be a smooth transition: With a few exceptions, almost all ProLine components are downward compatible. You can combine a ProLine rail with all of our roof hooks made of aluminum or stainless steel and add a ProLine module clamp. In addition, we are offering webinars and trainings in which we explain the transition and the benefits of the new products.

Which flexibility does ProLine offer for pitched roofs?

Flexibility is particularly important in the development of solar mounting systems for pitched roofs. Whether it is parallel to the roof or elevated – with the variety of different types of pitched roofs, inclinations and roof coverings, a stable mounting must be guaranteed for the respective requirements. Likewise, the mounting materials must be adaptable according to need and application. Thanks to the comprehensive selection and the modular structure of the PV mounting systems by Schletter, a high-performance solar installation is possible on practically any pitched roof. The systems support the mounting of all PV modules available on the market. In addition, modular systems considerably simplify both the planning and the assembly. The Schletter development team has taken this into account and further optimized the modular system logic. Instead of different module supports depending on the angle of inclination, module size or occupancy type (upright or transverse), all variants can now be realized with only a few universally applicable components. Schletter's mounting solutions are particularly durable, highly loadable, and quickly installed. In addition, static proof is always supplied for all roof systems.
