Fraunhofer Institute for Solar Energy Systems ISESoiling of mirrors in solar thermal power plants reduces the yield and affects economic efficiency. The goal of the project is the development of a device for automatic registration of soiling at sites for solar power plants for the qualification of plant sites as well as during power plant operation. Since yield reductions and cleaning costs represent a significant contribution to the economic efficiency of solar power plants, better understanding of the soiling characteristics at a given site would be a helpful criterion for risk reduction and financing when selecting and qualifying power plant projects and would support an optimization of the cleaning cycles during operation. | Duration: 08/2014 - 05/2018

In the project "AVUSPro" a device for the automated detection of soiling is further developed and prototypes are tested at sites with different environmental conditions. Methods for improved site characterization and improved operation of solar thermal power plants are also being developed. Here, for example, optimized cleaning and the analysis of soiling processes are important aspects. | Duration: 07/2019 - 07/2023
