Upon completing one year of operation, SkyFuel’s SkyTrough parabolic trough concentrating solar collectors system has also concluded its first testing period conducted by engineering firm Sargent & Lundy. The Solar Energy Generating Station (SEGS) II in Daggett, California was visited by the engineering firm, who reviewed the test methodology, daily performance data, and instrumentation and engineering drawings for 24 data collection days. The firm concluded that "the thermal output of SkyTrough solar collector assemblies (SCAs) can be expected to achieve the predicted levels."
