Valk Solar Systems ValkSolarFix Low H=20mm (geponst gecoat PVC)

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

According to the manufacturer, the ValkSolarFix is designed for pitched warm roofs, flat roofs, 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, which it is designed to fit.

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