Digital platforms

Software makes energy profitable.

das.os controls the plant, das.flow finances it and das.care keeps it running. Three systems that interlock – across the entire life cycle of a building.

Manage · Finance · Operate
Principle

Hardware generates. Software decides.

A module delivers kilowatt hours. Whether that becomes a profitable system is decided elsewhere: by who pays for the plant, when which consumer runs, and who steps in before the yield drops.

Exactly these three questions are covered by our platforms. Each can be used on its own – and together they interlock across the entire life cycle.

Life cycle

Four phases. One continuous system.

An energy project doesn't end at commissioning. Each phase has its system – and each system hands over to the next.

  1. 01Finance

    The project becomes possible

    Pay-per-use instead of a loan: you pay € 0.12 per self-generated kilowatt hour. No equity, no rigid annuity.

  2. 02Build

    The envelope becomes a power plant

    BIPV facade, PV roof, storage and charging infrastructure are planned, produced and installed – from a single source.

  3. 03Manage

    The energy flows are orchestrated

    Six modules control, display, evaluate and bill every energy flow in the building – from peak shaving to tenant electricity.

Systems

Three systems. One control layer.

Each system solves its own task and can be booked individually. Use all three and you get a closed loop of financing, control and operation.

das.osThe Energy Operating System

An operating system for energy.

das.os connects generation, storage, consumers and billing into one system. Six modules control, display, evaluate and bill every energy flow in the building.

  • Orchestration controls – peak shaving and self-consumption
  • Monitoring shows load, grid supply and storage in real time
  • Analytics evaluates avoided peaks and savings
  • Billing settles tariffs, cost centres and tenant electricity

das.flowPay-per-use financing

The rate follows the sun.

das.flow finances your photovoltaic system through the electricity it actually generates. No loan on spec, no rigid annuity – you pay per kilowatt hour.

  • € 0.12 per self-generated kilowatt hour
  • No equity, no bank negotiations
  • Term up to 15 years, payments fully deductible
  • The yield risk is not yours

das.careOperation & 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: a building that runs profitably for good.

  • Five service modules, from € 0.15 per m² of gross floor area
  • System guarantee instead of individual manufacturer warranties
  • 24/7 hotline, on site within four hours
  • Manufacturer warranty extended by up to five years
Interplay

One building. Three systems.

A manufacturing business with 137,000 kWh annual consumption, 100 kWp on the roof and a battery in the plant room. This is how the platforms interlock.

das.flow

The plant is built without equity

€ 120,000 of investment, but no capital tied up: the plant is paid for through the electricity it generates. Instead of an annuity, the contract states a rate of € 0.12 per kilowatt hour.
