Ultimate Trough Testloop

© Timo Richert

A complete loop, consisting of two solar collector assemblies (SCAs) of 240 m length each, has been integrated in a plant in California. One collector assembly consists of 10 solar collector elements (SCEs). The aim of the project is to achieve a reliable basis of the fabrication and erection concepts and their respective costs. In addition the collector efficiency will be measured under working conditions to provide certainty for the design of upcoming solar thermal power plants.
