With KONTAS (Konzentrator-Teststand Almeria Spanien), energy researchers from the DLR Institute for Solar Research will be able to test parabolic trough collectors up to 20 metres long at any angle to the Sun and measure their efficiency. The new test stand can be used to evaluate complete modules of parabolic trough collectors as well as individual components such as mirrors and absorber pipes. DLR operates the new test stand at the Plataforma Solar de Almería with CIEMAT.
