Whether small residential systems or large-scale industrial installations – fischer solar systems offer suitable fastening solutions for pitched roofs with various roof coverings as well as for different layouts and orientations of PV modules. New possibilities for energy-generating façades are also opened up by the innovative PV clip system, including the sliding nut FSMN II M8 R.

The new fischer system solutions simplify installation, save time and ensure permanently secure and functional fastening of PV systems on roofs as well as façades.

Flexible solutions for energy from the roof
With fischer solar systems, installers and system providers benefit from smart solutions for mounting PV systems on a wide range of pitched roofs. The comprehensive portfolio is compatible with numerous roofing materials such as roof tiles, fibre cement panels, trapezoidal and standing seam sheet metal roofs. Rails, roof hooks, brackets and stud screws allow flexible adaptation of the systems to structural conditions as well as to different PV module layouts and orientations – without special tools or major roof modifications.

The basis is formed by fischer aluminum rails, which can be expanded into load-bearing structures using matching system components. The spacing of fixing points is designed according to snow and wind loads in line with applicable national standards. SolarFish aluminum rails are available in various profile heights – from 33 mm for cost-efficient PV installations, 44 mm for versatile mounting solutions, up to 83 mm for high load capacity with a reduced number of fixing points. The SolarMetal L-rail is specially designed for trapezoidal metal sheet roofs. Its profile is optimized for landscape-mounted PV modules and is already equipped with an EPDM strip on the underside.

Universal, pre-assembled aluminum clamps in black or silver securely hold PV modules of different thicknesses, depending on the version as mid or end clamps. fischer aluminum roof hooks offer, depending on the type, three- or four-way adjustability, flexible alignment for adaptation to almost any roof, and various size options depending on the tile type. This also allows larger tolerances to be compensated for, for example on renovation projects or older buildings.

Progress on the façade
The new fischer PV clip system simplifies and accelerates the planning and installation of approved, durable PV façades. The modular system enables the creation of complete, continuous module fields in landscape or portrait format and is suitable for all types of framed PV modules with mounting holes. Stress-free installation and load-optimized design – enabled by the FSMN M8 R sliding nut – ensure technically flawless execution even when materials expand due to temperature changes.

The latest generation of the system offers additional advantages: the screw locking feature is already applied to the serrated screw, the sliding nut includes integrated equipotential bonding, and it allows higher tightening torques when using power tools. Installation is straightforward: the PV clips are simply connected via the mounting holes of the framed PV modules. Together with suitable fasteners, they enable flexible direct fixing to concrete or load-bearing masonry. Alternatively, substructures made of wood or steel – for example in combination with the fischer Universal Rail System (FUS) – can be installed in between. Ventilated PV façades can be realized using aluminum substructures. This means that with just one product range, PV façades can be implemented economically and efficiently on all common substrates and substructures.

Minimally designed, adjustable joints and nearly invisible fastening components ensure uniform and visually appealing building façades.

Dream teams for solar ambitions
fischer system solutions for PV roofs and façades not only provide a future-proof solution to the energy transition for energy supply but also enhance the efficiency and longevity of PV installations. Private households and businesses alike benefit from easy installation, high product quality and the long-term safety of the systems.
