K2 Systems S-Dome 6.10 Base Set Flat Roof Solar Mounting System

Flat roofs present a unique challenge for solar installations: how to secure modules without penetrating the roof membrane and risking leaks. The K2 Systems S-Dome 6.10 Base Set solves this with a non-penetrating, ballasted foundation for a single module in portrait orientation at a 10° tilt, optimizing south-facing energy yield. This set includes two base rails, two EPDM protective mats, and two end caps, forming the core of a robust flat roof PV system. The aluminium rails (EN AW-6063 T66) and stainless steel fasteners ensure durability, while the EPDM mats protect the roof surface. Designed for module lengths up to 2100 mm and widths up to 1170 mm, with frame heights from 30 to 50 mm (using compatible clamps, sold separately), the S-Dome 6.10 is TÜV Rheinland certified and suitable for membrane, bitumen, gravel, and green roofs. Ballast must be calculated per site to meet wind loads up to 2.4 kN/m² and snow loads up to 5.4 kN/m².

Who is it for

Solar installers and EPCs working on commercial or residential flat roof projects will find this base set essential. It suits those who need a reliable, non-penetrating mounting solution that preserves roof integrity and simplifies installation, whether equipping a single module or planning a larger array.

Tips

Always consult a structural engineer to calculate the required ballast for your specific roof and wind/snow loads. Use compatible K2 clamps to ensure a secure fit for modules with frame heights between 30 and 50 mm.
