SKAL-ET

As a successor of the Eurotrough II parabolic trough collector, seven
collectors with an overall length of 800 m and an aperture area of 4,350 m² were developed. For the first time ever, a single drive unit was used to actuate 12 linked collector elements with an overall length of 150 m. The Loop was integrated in the existing Solar Thermal Power Plant SEGS V of the Kramer Junction Operating Company in California, USA and have been operated continuously since April 2003. The aim of the project was a proof of concept of the planned fabrication and erection concepts and their respective costs. The collector efficiency was measured under working conditions to provide safety for the design of upcoming solar thermal power plants.

Parabolic Troughs

Proven state of the art for CSP

Over the years, sbp sonne developed and licensed three different types of parabolic trough collectors: the EuroTrough, the HelioTrough and the UltimateTrough. We are now focusing on the distribution and commercialization of the ‘HelioTrough’ and ‘UltimateTrough’, as these collector developments have been proven to significantly reduce costs and improve performance for large scale power plants.

The UltimateTrough collector for Concentrating Solar Power (CSP) plants is the world’s largest and most advanced parabolic trough collector. Measurements indicate that efficiency of the UltimateTrough is over 10% higher as compared to the benchmark collector.
