What I noticed
K2 Systems BasicRail is one of the most commonly specified on-roof mounting systems for UK solar installs — widely stocked at Segen and BEW. Aluminium rails attach to the roof via tile hooks that fit standard UK interlocking or plain tiles, with panels clamped to the rails using mid and end clamps.
Installation notes
You'll need to locate your roof rafters precisely before ordering — the hook spacing depends on rafter centres (typically 400mm or 600mm in UK homes). A good rafter finder or careful measurement from the loft is essential before install day. Verify clamp height matches your panel frame depth (typically 30–40mm) before ordering.
