Techno-economic analysis of receiver replacement scenarios in a parabolic trough field [PDF]

open access: yesAIP Conference Proceedings, 2016
The heat loss of an evacuated parabolic trough receiver of solar thermal power plants ranges typically between values below 150 and 200 W/m at 350°C. Defects, such as glass breakage by wind events and coating degradation, anti-reflection coating degradation or hydrogen accumulation in the annulus, decrease the annual electricity production.
