Solar Collectors

The plant uses Abengoa Solar’s ASTRO (Abengoa Solar Trough) parabolic trough collectors. The ASTRO collector is based on the 150m-long EuroTrough collector, which represents an improvement on the Luz collectors used in the SEGS CSP plants in California. ASTRO benefits from reduced weight and therefore reduced cost, while still delivering proven performance (established through EuroTrough tests conducted since 1998 at Plataforma Solar Almeria).

The ASTRO collector features an improved structural design, with a torque box that increases stiffness and reduces torsion and glass breakage. The EuroTrough collector design is used in most Spanish parabolic trough projects, including the commercial-scale Solnova and Andasol plants.
