Installation of PV Modules on Flat Rooftops with K2 Systems

In our last article we were evaluating the best K2 Systems mounting solutions for pitched roofs. This article will instead focus on flat roofs and the tailor-made K2 products for them.

Flat roofs with a ≤ 3° inclination are already very popular roofing options for commercial and industrial facilities. Buildings with flat roofs tend to have different size and roofing material. Also, many obstacles may exist on flat roofs such as chimneys, ventilation blocks or coolers.

Each of these factors require versatile and flexible solutions that allow the installation of PV modules without it being necessary to penetrate (and therefore damage) the roof and install the modules in a position on the roof that permits adequate access to sunlight. K2 system provides ballasted flat roof solutions that fit practically any demands of buildings and future PV-accessible building projects.

Dome 6 Systems

The newest flat roof solution from K2 is called Dome 6 and it comes with both a south orientation and E&W orientation configuration. The inclination angle of the PV module is 10° while permissible module dimensions are (L×W×H): 1448-2390 × 950-1170 × 30-50mm.

Dome 6 systems are delivered with pre-assembled rail sets and a click system for peaks to minimize the assembly time on site. With this solution the installer could have a 472 kWp plant ready after 2.5 days.

All components of the Dome 6 systems are made from premium material as seen below:

        • Peak, SD, mounting rail, MidPlate, EndPlate, Connector, Porter, MiniClamps: Aluminium EN AW-6063 T66 and AW-6082 T6
        • Windbreaker: Magnelis
        • Mat S protective mat: EPDM
        • Small parts: stainless steel (1.4301) A2-70
