More energy from every square metre. We activate the roofs, facades and open areas of industrial and commercial sites and connect them into one intelligent energy system.
Grid fees are rising, prices fluctuate, peak loads hit the bill twice. Anyone who doesn't generate their own power renegotiates every year – without a negotiating position.

your fixed price period ends – then you negotiate from scratch again

das.core activates every surface your site already has – and connects generation, storage and consumption into a system that optimizes itself.

Pay-per-Power leasing model
01Envelope
Roof, facade, shading and open space are activated for energy – even where conventional photovoltaics fail structurally or aesthetically.
02Generation
Roof and facade complement each other: the roof delivers the peak, the facade the steady profile in morning, evening and winter hours.
03Storage
The storage system raises self-consumption and caps peak loads – exactly the item that hits hardest on the grid bill.
04Control
Generation, storage, charging infrastructure and building technology are optimized against each other in real time – forecast-based instead of reactive.
01Ultra-light photovoltaics for roofs and facades with limited structural reserves.
02Energy generation becomes part of the architecture – as a high-quality ventilated building envelope.
03Engineered facade build-up with integrated energy generation and defined rear ventilation.
04High-efficiency modules for maximum use of large roof areas.
05Parking areas are covered and generate electricity – from translucent glass PV elements in free formats.
06Sun protection above windows and terraces becomes a yield area – one component, two jobs.
07Storage decouples generation and consumption and maximises self-consumption.
08Fleet charging with dynamic load management directly from your own generation.
09Precisely captures generation and consumption – the foundation of efficient energy management.
10Power electronics and metering as the backbone of a controllable energy system.
You pay for the energy your building generates – not for the system. das.flow handles financing, operation and billing and makes your electricity price predictable over the entire term.

No two buildings are alike. That's why we combine our technologies to match use, architecture, energy demand and economics.
Large surfaces. High energy demand. Maximum self-generated power use.
Lightweight roof and facade solutions for buildings where conventional PV reaches its limits.
Architecture, energy generation and e-mobility intelligently connected.
Roof and facade become part of a sustainable energy supply.
01. Analysis
Analyse the building, its energy consumption and the available surfaces.
02. Planning
Develop the economically optimal combination of building envelope, energy generation, storage and consumption.
03. Financing
Purchase or Pay-per-Power – matched to your investment strategy and energy demand.
04. Production
High-quality photovoltaic solutions from our own development and production in Austria.
05. Implementation
Coordinated installation, electrical engineering and system integration from a single source.
06. Operation & service
Monitoring, maintenance and continuous optimisation via das.os and das.care.
Buildings whose envelope no longer just protects, but produces – in existing buildings and new builds alike.
Send us the key facts about your building – we assess facade surfaces, orientation, potential and feasibility.
No – orientation, substrate, shading, fire protection and structural load capacity are always assessed on a project basis. In our free facade analysis we clarify these points upfront and show which surfaces can be activated economically.
Yes. Our modules are manufactured in Austria and can be adapted in colour, surface and format to the architectural concept – including special formats for existing grids.
Per square metre the annual yield is lower, but the yield profile is considerably more even. Facades deliver power especially in the morning and winter months – exactly when consumption in the building is high.
Cabling runs concealed within the substructure and is defined together with the electrical planning. In existing buildings we use existing shafts and routes where available.
Via das.care: remote monitoring, regular inspection, cleaning and servicing. The system is continuously monitored via das.os, and deviations are reported automatically.
Yes – in fact, that is the most economical route. Scaffolding, substructure and insulation are needed anyway; the additional cost of the energy-active envelope therefore pays off considerably faster.
Depending on the federal state and system size, investment grants, tax benefits and renovation subsidies may apply. We review the currently available programmes as part of the project analysis.
