K2 Systems used the latest edition of Intersolar Europe 2026 to unveil an expanded mounting system portfolio spanning rooftop, façade, carport and ground-mounted applications, alongside an updated digital ecosystem and the company's first sustainability report.

On flat roofs, the K2 GreenRoof 2.0 has been reworked to combine roof greening and photovoltaics more efficiently, with fewer components and a higher degree of pre-assembly speeding up installation. The system supports 10° and 15° tilt angles, multiple orientations and configurations, with freely selectable row spacing. Its generous roof clearance also favours plant growth, giving modules a cooler microclimate and reducing temperature-related losses.
The Dome 6 family, core of the conventional flat roof range, gains the Dome 6.07 Classic Portrait, the first Dome implementation with portrait-orientation modules at a 7° tilt, alongside a new Xpress Connector offering tool-free rail connection, integrated potential equalisation and lightning current capacity.

Pitched roof solutions include a tile replacement system for concrete tiles, the K2 4Tile, which eliminates tile processing in most cases and rules out the risk of tile cracking under heavy snow loads. More notably, the new SingleHook Slate brings the SingleRail system to slate roofs for the first time, a segment the company describes as one of the most demanding disciplines in PV installation due to brittle materials, varied laying patterns and often protected building structures. The hook allows for lateral connection, making installation faster than the previous method of screwing from below, and offers seamless height adjustability.
The façade range, K2 WallPV, has become established across Europe and adds a CrossConnector T alongside the CrossConnector Clip, enabling faster connection between insertion rail and base rail with a single screw, while also establishing potential equalisation in the same step.

The ground-mount segment, which accounted for more than half of new European PV capacity last year, sees the launch of the K2 Pi-Rack, a steel structure system built for fast installation and scalability on large projects. Modules are inserted via a double-sided slide-in profile and clamped tool-free from below. "We developed the Pi-Rack to optimally support the technical and logistical demands of large ground-mount installations," said Katharina David, Co-CEO of K2 Systems. "Fewer components, minimal tool requirement and genuine adaptability to terrain and module types. This delivers measurable time and cost advantages for our customers."
Variant V: engineered for wide spans
The carport line grows with Variant V, a twin-post V-frame system designed for wide spans and sites requiring maximum structural stability, spanning up to four parking spaces with a clear height of just over 3 m. "Carport projects have their own complexity, from structural design through planning permission to completed installation," said Willem Haag, Co-CEO of K2 Systems. "That is exactly why we accompany our customers through every project phase."

On the digital side, the MyK2 Dashboard now consolidates the company's planning software, product catalogue, documentation and pricing tools into a single interface. Its AI assistant, K2 KAI, has been extended beyond German and English to French, Italian and Spanish.
The company also published its first sustainability report under the VSME standard, covering environmental, social and governance indicators. "The energy transition needs not just the right products, but companies that take responsibility for their footprint," said Co-CEO Katharina David. (TF)
