Large solar thermal systems supply heat to district heating, industrial companies and large properties.

Large solar thermal systems are usually mounted on the ground and have a collector area of at least 500 m². Here is the Marstall system, Denmark, with a gross collector area of 33,365 m².

Large solar thermal systems remain unsealed open areas and offer great opportunities for biodiversity, such as the system in Randegg, South Baden, with a gross collector area of 2,400 m².

Large solar thermal systems are also possible on large, contiguous roof areas, as here in Crailsheim, Baden-Württemberg. Integration into roof surfaces offers additional architectural opportunities.

Working on the topic since 1995…

Solites experts began gaining experience in the development, simulation and realisation of solar thermal systems as early as 1995. As pioneers in this field, we developed and tested various hydraulic concepts for collector arrays, control algorithms and other innovative approaches in scientific projects and pilot systems.

Large solar thermal plants in Germany and Europe

Step by step, the technology for large solar thermal systems continued to develop. Over the years, the largest solar thermal systems in Germany or Europe have each been realized with our technical advice.

Thanks to this extensive experience, we have coordinated the development of the Europe-wide market for large solar thermal systems, supported by various funding projects. For example, we have advised political decision-making bodies on market development in Thuringia, the Neckar-Alb region, the Auvergne-Rhône-Alpes region, Styria, Denmark and other regions.

Thanks to our experience, we are a know-how leader in the field of large solar thermal systems and their system integration.

We are constantly researching the further development of solar thermal technologies and their system integration and advise on the implementation of systems.

Solites provides several internationally recognized experts in technical and advisory committees, for example in tasks of the IEA (International Energy Agency).
Here you can find some of the committees in which Solites participates.

We also share our knowledge of solar and renewable heating networks as part of our knowledge transfer.

Solites advises on the development of VDI guidelines, such as VDI 4190 Sheet 4 Heating Networks (in German language).
