K2 Systems Debuts P-Rack Ground-Mount System at KEY 2026, Adds S Dome for C&I Rooftops
Alessandro Papaianni, K2 Systems' Country Manager for Italy, walks through the company's stand at KEY The Energy Transition Expo 2026 in Rimini, introducing the new P-Rack ground-mount racking alongside the established N-Rack and S Dome C&I rooftop systems.
P-Rack: A New Ground-Mount Platform Built Around Below-Module Fixing
Papaianni, K2 Systems' Country Manager for Italy, describes P-Rack as a newly launched, fully steel ground-mount structure with a tilt angle set to match each project's layout. The module fixing mechanism is accessible entirely from below, he says, so installers no longer need to work from above the array. The system is customizable in both depth and angle, he says, supporting tilt settings of 20, 15 or 30 degrees and configurations of two or three modules in portrait orientation. Papaianni calls it an easy, fast and economical installation solution, engineered project by project around layout needs.

N-Rack: Proven Ground-Mount Racking for Small and Mid-Scale C&I
N-Rack pairs a steel foundation pole with an aluminum superstructure. Papaianni says it suits small and medium-sized ground-mount projects, up to roughly 4 to 5 MW. Pole depth is adjustable, and installers can choose between a fixed concrete base or a foundation screw depending on site conditions. The above-ground structure is built entirely in aluminum, Papaianni says, and engineered for the wind and snow loads specific to each installation site. He describes N-Rack as a classic, versatile and economical option that complements the newer P-Rack line.

K2 S Dome: Reducing Ballast and Protecting Flat Roofs in C&I Installations
For rooftop C&I projects, Papaianni points to the K2 S Dome, a flat-roof system available at 10 or 15 degree tilt. Its mounting method creates a standoff from the roof surface using PDM pads roughly 3 cm thick, which he says protects the underlying membrane, particularly TPO roofing. The modular PDM approach cuts the ballast needed on the roof, Papaianni says, lowering both installation costs and the additional load on the building structure. He also notes the system's B Roof T3 certification as a relevant credential for specifiers.

Frequently asked questions
What is new about K2 Systems' P-Rack ground-mount system?
Papaianni describes P-Rack as a newly launched, fully steel structure whose module fixing is done entirely from below, removing the need for overhead mounting work. It supports tilt angles of 20, 15 or 30 degrees and two- or three-module portrait configurations depending on layout.
What project sizes is the N-Rack system designed for?
Papaianni says N-Rack suits small to medium ground-mount installations, up to roughly 4 to 5 MW. It combines a steel foundation pole with an aluminum superstructure fixed on concrete or a foundation screw.
How does the K2 S Dome protect flat roofing membranes?
The S Dome’s mounting method keeps the array about 3 cm above the roof surface using modular PDM pads, which Papaianni says shields materials such as TPO membranes from direct contact. This standoff also reduces the ballast weight required on the roof.
Is the K2 S Dome certified for roofing standards?
Papaianni cites a B Roof T3 certification for the S Dome system. He presents it as a relevant credential for specifiers evaluating flat-roof C&I installations.
Can N-Rack and P-Rack be adjusted for local wind and snow loads?
Papaianni says N-Rack is engineered for the wind and snow loads of the installation site, with adjustable pole depth. P-Rack is customizable in depth and tilt angle to match layout requirements, though he didn’t describe site-load engineering for it separately.
Where can installers get more information on K2 Systems' mounting range?
Papaianni invites visitors to the K2 stand at KEY Energy or the company website, where distributor and contact references are listed. He offers direct engineering support for designing projects around these systems.
