System optimized for faster installation on green roofs
• Reduced number of components • Flexible module layout and orientation: 10°/15° tilt, Portrait/Landscape, A/V/S shape • Freely adjustable row spacing • Clamping on the long side
Portrait installation with 7° tilt
• SharedRail system reduces material usage and installation effort • Larger ridge gap allows for easy maintenance and improved aerodynamics • Enhanced rear ventilation thanks to increased clearance to the roof covering • Long-side (LS) clamping fulfills the standard requirements of PV module manufacturers • For all module sizes
For higher load requirements, faster installation
• Faster installation thanks to pre-assembled components • Landscape installation with a 10° tilt • Long-side (LS) clamping fulfills the standard requirements of PV module manufacturers • Suitable for PV modules with a width of 1134 mm and a length of up to 2500 mm • Lightning current-carrying capacity with the new Dome 6 Xpress Connector
Connecting Strength – better and faster!
• Simple snap-in design for tool-free installation • Optimized component design • Integrated equipotential bonding • Meets advanced requirements with lightning currentcarrying capability
Optimized rail connector
• Simple snap-in mechanism for tool-free installation • Integrated equipotential bonding
Tile replacement solution for the most common types of concrete roof tiles
• No need for tile forming • No risk of tile breakage under high snow loads due to the roof hook bracket resting on the tile • No tile modification required • Attractive appearance in two colors
The light version of our popular SingleHook 3S
• Reduced material thickness • Less tile modification required • Simpler and more flexible installation • Suitable for regions with lower snow loads
Roof hook for slate roofing
• Now also compatible with the SingleRail System • Faster installation thanks to side mounting • Greater flexibility due to height adjustability
New application area: metal roof tiles
• Adapter for angle adjustment • Inserted in BasicRail • Sealing of the BasicClip with a CSM adapter made of EPDM
High version of MiniRail
• For trapezoidal sheet metal • Portrait and landscape installation • Greater clearance to roof covering thanks to 60 mm component height • Improved rear ventilation of the PV modules • Space for optimizers
High version of MultiRail
• For trapezoidal and corrugated sheet metal • Landscape installation • Greater clearance to roof covering thanks to 100 mm component height • Improved rear ventilation of the PV modules • Space for optimizers
MultiRail in 150 mm length
• For trapezoidal sheet metal • Landscape installation • Depending on load requirements, fastening with 2 or 3 screws is possible, providing greater flexibility • Simplified logistics: only one component
New ground-mounted system
• Few components, simple and highly stable • Screw-free module installation in a double-sided insertion profile • Module tilt of 10°–20° with 3x portrait, 10°–30° with 2x portrait • All steel components, including driven piles, feature a zinc-magnesium-aluminum coating • Organized cable management directly within the purlins or along the rafter profiles • Also available with aluminum rafters
Flexible and scalable PV carports
• Support geometry enables smaller screw or concrete foundations • Support spans of over 10 m possible • Project-specific design • Simple module installation with clamping from below • Design with or without trapezoidal sheet metal • Optional rainwater management
Secure connection to various façade materials
• Concrete and solid masonry: WallPV FacadeRail • Concrete with existing insulation: WallPV PerfoRail • Trapezoidal and corrugated sheet metal: WallPV MultiRail
CrossConnector T and CrossConnector Clip
• Integrated equipotential bonding • Faster installation • Architecturally appealing design
Alpha PV-Clip: Simple cable management
• One-handed installation on the module frame possible • Clean cable routing, both vertically and horizontally
AddOn XS: Landscape installation with a single rail layer
