PV Clamps: End and Middle Clamps for Solar Modules
Clamps in this category secure photovoltaic modules to aluminium mounting profiles. The range covers end clamps for the edges of a row and middle clamps for the gap between two panels. Variants differ in working height, finish and fixing system. They are intended for installers of PV systems on flat roofs, pitched roofs and ground-mount structures.
What you will find in this category
- End (side) clamps H30, H32, H35 and H40 in aluminium 6060, with an M8 hole, in raw, anodised or painted finish.
- Adjustable end clamps with sliding grooves for module frames of 30-50 mm, in raw or anodised aluminium 6060.
- Middle clamps H8, H11, H24 and H25, including low-profile versions, with an M8 hole and L50 length.
- Clamps with grounding pin in aluminium 6063-T66 or EN AW 6060, for potential equalisation between module and structure.
- KLIK click-latch end and middle clamps L50 (type 2), in silver or black, with bolt and nut or A2 bolt.
- End and middle clamps supplied with screw and insert for 30 mm or 35 mm frames, using DIN 912 M8x20 or M8x25 screws.
- Synerga ZU-1 mounting bracket in 304 (1.4301) stainless steel, 30×30×30 mm, M8 thread, for carports and ground-mount structures.
How to choose
- Frame thickness: the working height must match the module frame. Fixed end clamps cover 30, 32, 35 and 40 mm. Adjustable versions cover 30-50 mm.
- Clamp position: use end clamps at the ends of a row and middle clamps between adjacent panels.
- Material and finish: choose aluminium 6060 or 6063-T66. Finishes include raw, silver or black anodised, painted and black powder-coated.
- Grounding: choose a clamp with a grounding pin if you need potential equalisation without additional washers.
- Fixing system: pick the M8 hole, the KLIK click latch, or a set with screw and insert to suit your rail and fasteners.
Typical applications
These clamps hold PV modules on aluminium mounting profiles on flat and pitched roofs. End clamps finish the panels in a row. Middle clamps join two modules, and their teeth grip the frames to prevent shifting. Several versions suit T-slot, hexagonal-bolt and trapezoidal profiles. The Synerga ZU-1 bracket supports clamps on carports and ground-mount structures.
Frequently asked questions
Where are end clamps and middle clamps used?
End clamps finish panels placed in a row, at the edge of the array. Middle clamps are used between two adjacent panels.
Which clamps provide grounding?
Versions with a grounding pin. The aluminium 6063-T66 models listed provide potential equalisation without additional washers.
What is the maximum tightening torque for KLIK clamps?
The KLIK side clamps with A2 bolt in this category state a maximum tightening torque of 20 Nm.
