Schletter Group

Founded in 1968 and based in Germany, Schletter is a globally recognised manufacturer of solar PV mounting systems. Known for engineering excellence and a robust product range, Schletter designs its mounting systems to match the 25-year lifespan of solar PV modules. Made from high-strength steel and aluminium, the systems offer exceptional load-bearing capacity, durability and corrosion resistance. They are suitable for a wide range of roof types and ground-mounted installations.

Schletter Product Range

Schletter provides solutions for pitched roofs, flat roofs and ground-mounted PV installations.

Pitched Roof Systems – Rapid 2+: Compatible with tile, corrugated and standing seam roofs, the Rapid 2+ system allows for fast and secure module mounting with fewer components, reducing installation time.

Flat Roof Systems – FixGrid: Designed for flat roofs, this ballasted system minimises roof penetration while maximising energy yield through optimal module positioning.

Ground-Mount Systems: Schletter’s FS Uno and FS Duo systems are engineered for long-term performance in utility-scale projects, with options for different terrains and foundation types.

Custom Solutions: Bespoke mounting solutions are available for projects with specific requirements.

Residential Products

Schletter offers a range of roof hooks designed to reduce the number needed per installation, lightweight Pro Rails with flexible clamp and hook positioning, and clamps in black or silver with integrated earthing pins for enhanced safety.

Commercial Products

FixGrid Pro features a compact, modular design that reduces transport and storage costs while optimising panel placement for shading and wind loads. FS Duo is designed for challenging terrains such as bedrock or landfills, with hybrid and pre-drilled pile solutions. SingleFix provides side-mounted installation for superior pull-out force while complying with roof manufacturers’ guidelines.

Proprietary Features and Design Principles

Stronger materials ensure long-term durability, with marine-grade aluminium and stainless steel rated for 400 years. Pro systems are tested to withstand high wind and snow loads, offering enhanced structural safety. The mounting systems are adaptable to different climates, including coastal areas and heavy snow regions. Fewer components simplify installation, reducing costs and labour time. Internal rail connectors allow greater freedom in clamp and hook positioning, while built-in earthing features in clamps eliminate the need for additional grounding cables.

Warranty

Schletter offers a 25-year warranty on its mounting systems.

Tools and Apps

Schletter’s Configurator Tool simplifies system design by integrating Google Maps for accurate roof mapping and using an extensive load database for wind and snow calculations. Available in multiple languages, it supports multiple roof designs within a single project. Fast configuration mode suggests the best layout based on system size, alignment and structural loading, while professional mode allows for manual parameter selection.

Installer Benefits

Schletter provides training, technical resources and installation guidance to help professionals optimise system performance. The House of Schletter knowledge hub offers in-depth resources, interactive tutorials and online training. In addition, local support teams are available to assist with design and technical queries.
