K2 Systems presented its new intelligent assistant KAI at the recent trade fair in Munich. CEO Katharina David explains what’s behind the launch and what else the company had on show.

Can you tell us about KAI?

Katharina David: This year, we’re presenting KAI as an exciting new innovation. It’s our AI-based digital agent – still small and growing, but learning quickly from the knowledge base at K2. It’s available 24/7 and already handles many of the everyday questions our installers bring to us.

Matjaž Grošelj of K2 Slovenia: “We face strong competition”

So KAI is the result of K2 plus AI?

Exactly – K2 and AI. This guy doesn’t sleep.

You have said that KAI learns fast without a great deal of input.

Yes, but we do feed it with structured information. We’ve also built in a feedback loop: if an installer isn’t satisfied with an answer, we can refine the model to improve responses. The agent has a layered architecture, allowing it to go deeper if needed.

SunIsUs – from project rights to AI-powered asset management

How does that work in practice?

At the first level, it provides answers about our installation systems and digital tools. If that’s not enough, KAI drills down. At the third level, it draws on the full body of K2’s collective knowledge to support customers more profoundly.

And if KAI is unable to answer?

Then our technicians step in. But KAI is the quick, low-friction first step.

You used the slogan “From Base to Peak” in Munich. What’s behind this?

Installers familiar with our flat-roof systems – especially the K2 Dome – will recognise “base” as the lower clamp. “Peak” refers to the upper clamp. The commercial and industrial segment is growing, and we’ve refined the dome system in response.

Sigenergy – new app optimises energy management with AI

What new systems did you present?

One highlight was the D-Dome 6 Xpress LS. It’s made for large-format modules, which are harder to corner-clamp due to higher loads. This version enables long-side clamping, and this is fast and intuitive – that’s the “peak”. Our focus this year is on both digital innovation such as KAI, as well as physical design tweaks that make mounting quicker and easier.

C&I systems are a focus this year. What can installers expect?

We put strong emphasis on safety, quality and durability. With K2 Base, installers can calculate systems and mounting setups, generate ballast plans, part lists and more. We’re increasingly covering more module types and foil systems, and are working closely with more suppliers. It’s about giving installers the confidence and clarity they need to get on with their tasks.

More on mounting at pv Europe.

You also advocate for European manufacturing, which comes with its challenges. Why is that important?

Mounting systems get less attention than modules or inverters when it comes to European production. But certification under Eurocode brings high legal requirements. I keep a close eye on that, including through my work with the federal association, BSW-Solar.

The smarter E Europe – a blueprint for tomorrow’s energy

Regional production is also a sustainability issue, wouldn’t you agree?

Exactly. Real sustainability matters to us. A lot of solar manufacturing has moved out of Europe, but we’re committed to staying. While we don’t produce ourselves, around 85% of our products come from European factories via local partners. It’s entirely feasible also because we completely stand behind this approach. We need more production in Europe!

Thank you.

In the Holma district of Malmö there is a large residential complex at Hyacintgatan 45. It was recently equipped with photovoltaics, like previous similar large-scale projects. The quarter was built in the 1970s as part of the so-called million dollar program. In order to create affordable housing, numerous settlements were planted on arable land.

15 buildings with 540 apartments

In this case it is the owners’ association Riksbyggen Brf Malmöhus 24, which includes 540 apartments. The solarization project was planned and installed by the BBK company.

In order to meet the high requirements, BBK first analyzed the market for solar components. “We chose solar inverters from Kostal and modules from REC from Norway,” says Daniel Ohlin, CEO of the BBK Group. “This guarantees high quality. It was also important to us that if we have any questions or problems, experienced and local technical experts can help us if necessary.” The selection of the inverters was preceded by extensive tests of various products and suppliers. The decisive factors were efficiency and service.

Some roofs more than 30 meters high

The Riksbyggen Brf Malmöhus 24 district consists of 15 buildings with different floor plans, some of which are higher than 30 meters. “We started installing solar modules on the first building in 2016,” Ohlin reflects. “We have equipped another building every year since then.”

The solar modules are mounted parallel to the roof pitch using the Dome Zero from K2 Systems.


Quality and service also played a crucial role in the selection of assembly technology. “In Sweden, no one has any technical experience with installation on such tall buildings,” reports the manager. “The wind loads are very high and the conditions for installation are sometimes extreme.”

Modules installed parallel to the roof

So far, 2048 N-Peak and Twinpeak 5 solar modules have been installed by REC. The substructure comes from K2 Systems. The solar modules were not mounted on stands, but rather mounted parallel to the roof pitch using the Dome Zero from K2 Systems. “This meant we didn’t need approval from the building authorities,” explains the manager. “The system also requires far fewer additions or fastenings to the solid wood roof substructure.”

All systems have the same structure and components to ensure longevity and reduce maintenance costs. “The installation went smoothly in all projects because all suppliers supported us in the planning,” praises Ohlin. “We were and are in constant contact to coordinate data and requirements.”

Borgholm is the solar city of Sweden

Around 650 kilowatts installed so far

Six of 14 buildings are now equipped with solar technology. The solar modules produce 650 kilowatts. 17 inverters were installed, EPC and Piko CI. All in all, 550,000 kilowatt hours of clean electricity have been generated so far.

It was important to planners and owners that the projects were economically viable. “At the beginning we planned to break even in eight years,” says Ohlin. “When electricity prices skyrocketed, we broke even after just four to five years.”

As a result, the systems that were first installed have already paid for themselves. The solar power goes via the house power distributors into the apartments and elevators, into the lighting of the stairwells and garages and into charging points for electric cars. (HS/hcn)
