Build a secure mechanical foundation for the array with solar PV mounting systems for pitched roofs, flat roofs and ground-mounted installations. Select rails, roof attachments, clamps, trays, ballast components and complete mounting bundles to suit the panel layout and roof or site construction. Mounting design must account for module dimensions, fixing zones, wind and snow actions, roof condition, edge distances, drainage, corrosion environment and the mounting manufacturer’s instructions. Confirm structural suitability and the exact bill of materials before equipment is ordered or installed.
