- and to provide basic tools for the design and analysis of the collector performance.
Course Contents
Solar thermal collector design and technology
This course was given by Víctor Martínez Moll from the University of Balearic Islands. It was an introductory course on solar thermal technology. The most important parameters for collector performance assessment were defined and the collector's efficiency curve was derived. Various collector types were presented ranging from non-concentrating technologies such as flat plate and evacuated tube collectors to concentrating technologies like Fresnel, Parabolic Trough, Solar dish and Solar Tower collectors.
Collector efficiency analysis with the tool “Kolektor”
Tomas Matuska from the Technical University of Prague gave an introduction to Kolektor a software he developed to simulate the energy output of flat plate collectors. The program was written in visual studio and allows the user to define many optical and thermal models. The students had the opportunity to get familiar with the software while solving application-related problems.
Optics for solar collectors
Ramon Pujol Nadal from the University of the Balearic Islands gave the course on collector optics. The students were provided with a comprehensive summary on the theoretcal background of optics for solar thermal collectors. The optical models were applied in a practical way by simulating a Fresnel collector using the ray tracing software Tonatiuh.
Optics simulation with the tool “Tonatiuh”
This course was given by Amaia Mutuberria from the National renewable energy center (CENER). Tonatiuh is a ray tracing tool that is used to assess a solar collector's optical parameters such as the optical efficiency and the intercept factor. The students had the opportunity to get familiar with the software at first hand. Fresnel collector was used by Amaia as an example to introduce Tonatiuh tool.
Solar thermal collector testing
Fabienne Sallaberry from the National renewable energy center (CENER) presented the most recent collector standards such as the ISO 9806:2013. The students got to know at first hand, how collectors are certified at CENER according to these standards.

Workshop on Storage Modeling
organized by Dr. H. Kerskes, Universität Stuttgart (D), March 30th, 2015
The aim of the one-day workshop is to give an introduction in the numerical modeling of different thermal energy storage systems. Numerical models of hot water stores will be discussed, beginning with simple model up to more detailed and scientific models. Another topic will be the modeling of sorption processes used for thermal energy storage. Different numerical tools to solve the models discussed will be presented.
