Parabolic Trough technology bases its operation on solar tracking and the concentration of solar rays on receiving tubes with high thermal efficiency, located on the focal line of the cylinder. In these tubes, a heat transmitting fluid, such synthetic oil, is heated to approximately 752 ºF (400 ºC) by the concentrated solar rays. This oil is pumped through a series of heat exchangers to produce steam. The heat present on such steam is converted into electric energy on a conventional steam turbine.
