PVT-Copras – PVT-Collector with Overheating Protection by Rollbond Absorber Shifting

The aim of the project is the development of a single covered PVT collector with high electrical and thermal efficiency and a self-securing overheating protection realised by absorber shifting. An aluminium roll-bond absorber is used as heat exchanger, which enables good thermal properties on one hand and smart integration of the overheating protection mechanism on the other. The development includes the construction of a prototype on a scale of 1:1, its performance measurement in the laboratory and an assessment of its behavior when exposed on the test roof of the institute.
