Every manufacturer on its own
Module, storage and inverter each have their own warranties, deadlines and contacts. Nobody is responsible for the system as a whole.


With das.care we operate and monitor your entire energy system – from the building envelope to the energy billing. The goal is a building that runs energy-efficiently, economically and climate-friendly for good.
Without das.care, only the warranties of the individual components apply. They cover material and production defects – not the interplay of facade, roof, storage and control.
Module, storage and inverter each have their own warranties, deadlines and contacts. Nobody is responsible for the system as a whole.
Wrong settings, an installation issue or components that don't work together – none of that is covered by any manufacturer warranty.
Without monitoring, a gradually weakening plant only shows up when the annual statement arrives. By then the yield is lost.
das.core turns the building envelope into a power plant. das.care keeps that power plant in optimal operation across the building's entire life cycle – technically, energetically and commercially.
01Generate
BIPV facade, PV roof, storage, heat pump and charging infrastructure form the power plant. Delivered and integrated through das.core.
02Operate
Monitoring, maintenance and service keep the plant at its design point for decades. Deviations are reported before they cost yield.
03Optimise
Load management, peak shaving and storage control shift energy to where it is worth most – up to 70 % self-sufficiency in the ecosystem package.
Each module can be booked individually and added at any time. Billing is per square metre of gross floor area and month – predictable, without surprises.
All prices per square metre of gross floor area per month, plus VAT.





The base operation: the plant is continuously monitored and fully checked once a year. Prerequisite for the das.care.guarantee.
The difference is not the length of the guarantee but its subject: components or plant.
Covers material and production defects of the individual components.
Not covered: installation, integration, interplay.
We guarantee that the plant works as a system.
Prerequisite: continuous monitoring via das.care.basic.
System guarantee plus maintenance – and five more years.
Includes the full scope of das.care.basic.
A fault rarely reports itself during office hours. The das.care.hotline is staffed around the clock, and deployment starts within four hours.
das.care.all.in.one bundles operation, optimisation, energy flow management and system guarantee into one solution – with a 5 % discount on the module prices.
Beyond the monthly module price, only services that actually occur are billed.
All module prices are per square metre of gross floor area and month, plus VAT.
A system guarantee. The manufacturer warranty covers material and production defects of individual components. The das.care.guarantee additionally covers correct installation, wiring, integration of the components and the interplay of facade, roof, storage and control.
Yes. das.care.basic is the prerequisite for the das.care.guarantee, because only continuous monitoring can prove how the system was operated.
das.care.basic monitors and checks once a year. das.care.plus additionally includes regular maintenance, spare parts management, prioritised fault resolution and on-site service – and extends the manufacturer warranty by approx. 5 years.
Per square metre of gross floor area and month: € 0.15 for basic, € 0.45 for plus, € 0.25 each for management and flow, € 0.35 for clean. Usage-based items add € 6 per bill, 10 c per kWh energy platform and a 15 % peak shaving fee.
Yes. Each of the five modules can be booked individually and added at any time. Bundle all of them and das.care.all.in.one gives you a 5 % discount.
The das.care.hotline is staffed around the clock. After a report, the service is ready to deploy within four hours. With das.care.plus, fault resolution is additionally prioritised.
Setting up das.os costs a one-off € 5,000. After that, monitoring, control and reporting run through the platform.
