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.
das.careBETRIEB & SERVICE
Operation & service
We look after your building.
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.

Starting point
The manufacturer warranty ends where operation begins.
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.
Faults without material defects
Wrong settings, an installation issue or components that don't work together – none of that is covered by any manufacturer warranty.
The yield drops unnoticed
Without monitoring, a gradually weakening plant only shows up when the annual statement arrives. By then the yield is lost.
Life cycle
das.core generates. das.care operates.
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
Energy comes from the envelope
BIPV facade, PV roof, storage, heat pump and charging infrastructure form the power plant. Delivered and integrated through das.core.

02Operate
The system stays on target
Monitoring, maintenance and service keep the plant at its design point for decades. Deviations are reported before they cost yield.

03Optimise
Operation becomes self-sufficiency
Load management, peak shaving and storage control shift energy to where it is worth most – up to 70 % self-sufficiency in the ecosystem package.

Modules
Five modules. One operation.
Each module can be booked individually and added at any time. You only pay for what your building actually needs – the scope grows with the plant.
Scope and conditions are tailored to your building – you'll receive your offer within 24 hours.
The system stays in view.
The base operation: the plant is continuously monitored and fully checked once a year. Prerequisite for the das.care.guarantee.

das.care.guarantee
Without das.care, manufacturers are liable. With das.care, we are liable for the system.
The difference is not the length of the guarantee but its subject: components or plant.

Fragen
What you should know about operation, warranty and billing.
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.
As a monthly rate based on your building's gross floor area and the modules selected. On top of that, only usage-based items that actually occur are billed – such as tenant electricity and charging statements or the energy platform. We prepare your individual offer after your enquiry.
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 works out cheaper than the individual modules.
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.
Yes, setting up das.os involves a one-off fee. After that, monitoring, control and reporting run through the platform. The amount depends on the scope and is stated in your offer.
