Abstracts

The results of nearly 20 years of Paradigma research, development as well as the practical experience with more than 30.000 already realized solar systems according to the AquaSystem principle give enough evidence that CPC-ETC technology with pure water as heat transfer fluid is probably the most promising way to realize large-scale solar-thermal systems (LSS) and demanding solar-thermal systems at all. High temperature collectors increase the efficiency factor, allow an all-season application and are the key for effective heat storage.
