In the new building area “Freiburg-Gutleutmatten”, mondas® is used to monitor 38 solar systems in a solar local heating network and analyze their operation.
In the newly built quarter with 525 apartments, badenova-Wärmeplus GmbH & Co. KG installed a solar local heating supply. The special feature: Yield surpluses of individual solar systems can be transported to defined buildings without having to put the entire grid into operation. This cooperative supply model guarantees minimal heat distribution losses and a higher solar energy share in the network.
The remaining demand in winter and in the transitional periods is covered by a district heating network based on a biogas CHP plant. This district heating network can be connected on a pulse basis.
The mondas® IoT platform uses AI algorithms to analyze the operating states of the solar systems in real time and forecast heating requirements.
The project is scientifically accompanied by the Fraunhofer Institute for Solar Energy Systems ISE.
Features of the mondas® IoT Platform:
- acquisition and analysis of measurement data, forecast of future demand values
- commissioning monitoring of the decentralized solar systems
- implementation of AI control algorithms in analytic software
- control of the intelligent solar heating network
The operating states of all 38 solar systems are recorded decentrally and interpreted by the mondas® Analytic software. Each solar system has its own storage and control unit.
Over 4,000 Measurement Points Monitored in Real Time
The mondas® IoT platform collects all the necessary measurement and yield data from all 38 solar systems, as well as the forecast demand values. The IoT platform analyzes data from over 4,000 measurement points in real time. The Fraunhofer Institute for Solar Energy Systems ISE developed the corresponding control algorithms.

Many Advantages for Climate and Environment
The pulsed operation of the heating network results in numerous advantages:
- reduced heat distribution losses in the network
- less residual energy demand from district heating
- maximum use of local solar energy potentials
- electricity market-oriented operation of the CHP plants
The intelligent solar local heating network “Freiburg-Gutleutmatten” received the prestigious Smarter E Award in the category “Outstanding projects” in 2019.
