The customer sought the most aesthetically pleasing,
lightweight, and wind-resistant solution for vertically
mounting its solar array to a standing seam façade
wall, without compromising the integrity of the profile.
They selected the direct-attach, rail-less PVKIT solar
mounting solution paired with the S-5-U™ clamp. This
low-profile, lightweight solution not only surpassed
their aesthetic expectations, but was also engineered
to withstand the high winds typical of the area.
The building incorporates a lower TPO roof hosting a tilted solar array, an upper standing seam metal roof
utilizing the S-5-U Mini/UniRac rail-based solar racking system, and a vertical façade wall featuring the PVKIT and S-5-U clamp solar mounting system.
Namaste Solar recommended the direct-attach PVKIT rail-less solar mounting solution paired with the S-5-U clamp, for the façade mounted array. Together, the solar mountings provided a lowprofile, sleek, lightweight solution to secure the solar array to the standing seam wall.
Additionally, it enabled the owner to achieve a design engineered to withstand the region’s high winds. By directly attaching the PV to the seams, it provided installation efficiency and flexibility, and distributed the load more uniformly into the structure.
The clamps perform a secondary function as wind clamps, often referred to as “External Seam Clamps” (ESC). These wind clamps measurably increase the roof’s wind uplift resistance capacity, preventing multiple modes of failure, including seam separation and clip disengagement when used at roof clip locations.
Over time, the solar system will offset 69% of the building’s electrical consumption. The PVKIT solar attachments provided the ideal mounting solution and aesthetic appeal the customer desired without penetrating the standing seam profile.
