We are experienced conducting practical research in sustainable heat supply.
We consider our research topics to be highly relevant to the future of our environment and our society. From the initial idea for innovative questions to the acquisition of funding and project implementation, the Solites team is always happy to take on new and exciting challenges.
We work in interdisciplinary teams with politics, industry and science to develop solutions that are used in the market.
For us, completing a project also means further developing the question for the next project idea.
Coordinating, cooperating, acquiring funding
We coordinate research activities and cooperate in national and international consortia. We acquire our funding at regional, national and European level, e.g. from state ministries, in the 8th Energy Research Program and in the NKI, in the EU programs Horizon Europe and Life and others.
As a non-profit Steinbeis company, we carry out our research projects independently.

International research networks
Thanks to our extensive research expertise, Solites employees have been and continue to be involved in IEA (International Energy Agency) tasks:
- SHC Task 45 (Large Scale Solar Heating and Cooling Systems)
- SHC Task 55 (Integration of Large SHC Systems into DHC Networks)
- SHC Task 68 (Efficient Solar District Heating Systems)
- ES Task 32 (Modeling of Energy Storage for Simulation)
- ES Task 39 (Large Thermal Energy Storages for District Heating)
- ES Task 45 (Accelerating the Uptake of Large Thermal Energy Storages)
- DHC TS 5 (Integration of Renewable Energy Sources into Existing District Heating and Cooling Systems)
At European level, we are members of the RHC-ETIP and DHCplus working groups.
Solites employees prepare expert reports for international funding bodies and advise political decision-makers.
Our research focuses
Our research focuses on technologies that enable emission-free heat generation, in particular solar thermal energy, geothermal energy, heat storage, heat pumps, waste heat, sector coupling and their system integration.
The aim of our considerations are integrated systems for heat generation for district heating, large properties and industry.
From the investigation of individual materials or technologies to the heat supply of large cities, we deal with many topics, e.g:
- Materials research for heat storage and geothermal probes
- Further development of construction methods for multifunctional heat storages
- Development of simulation models and subprograms
- Simulation work and studies
- Development of integrated systems for heat generation and supply
- Knowledge transfer and market development
- Development of measures for energy-conscious behaviour
- Scientific and technical support for implementation projects
- Creation of simple calculation programs for the professional public
- Monitoring of realised systems
- Development of the system integration of innovative solar thermal systems
- Application of machine learning and AI to control systems
