Quality Assurance for Solar Thermal Collector Production

The production of solar thermal collectors is already a well-established technology, although there is high potential for implementing quality assurance measures for several parts of the production procedure. Therefore, this project works on the development of methods to verify the transmission rate of the collector's covering glass. This could be realized in a simple way, so that investment costs for the collector manufacturers can be kept as low as possible. First measurements showed satisfying results compared to reference measurements at approved testing institutes.
