Summary of the project

As part of the research project, a collector with low production costs is to be developed that consists primarily of glass (see figure below). Due to the simplified structure, cost-intensive production steps, such as absorber welding, are not necessary and enable an automated production process. The production costs can therefore be reduced by approx. 20% compared to conventional standard flat-plate collectors. A further advantage is the targeted construction height of less than 50 mm, which enables simplified installation and connection, so that further areas of application (especially in façade construction) can be opened up.

Through thermal modelling of the collector, flow simulations, accompanying metrological investigations and fundamental scientific studies, the defined objectives regarding performance, manufacturing costs and stability are to be investigated in depth. In order to successfully establish the collector on the solar thermal market, the practical requirements in terms of handling, installation and reliability must be taken into account and fulfilled.
