Valk Solar Systems ValkSolarFix Low H=20mm (punched coated PVC)

The ValkSolarFix Low H=20mm is a ballast-free mechanical anchor for mounting solar panels on flat roofs. It is made of aluminium and secured to the roof with screws or toggle anchors on wood or steel-sheet roof structures, or with concrete anchors on concrete. The screw or anchor length is selected according to the thickness of the roof insulation. The product sits on top of the roofing material, and its large base is designed to distribute pressure across the roof covering and insulation.

According to the manufacturer, the ValkSolarFix is designed for pitched warm roofs, flat roofs, and concrete, steel (0.75 to 2.5 mm) and wood substrates. It is listed as suitable for bitumen and mineral roof surfaces. It is intended for use with the ValkPro+ flat-roof PV mounting system, for which it is designed.

Stated features include no ballast on the roof, a waterproof fixing, and a storm-proof anchor. The manufacturer also states that it allows water to flow freely, reduces dirt accumulation, and provides heat regulation behind the panels.
