A parabolic trough is made of a number of solar collector modules (SCM) fixed together to move as one solar collector assembly (SCA). A SCM could have a length up to 15 metres (49 ft 3 in) or more. About a dozen or more of SCM make each SCA up to 200 metres (656 ft 2 in) length. Each SCA is an independently-tracking parabolic trough. [9]
It was built to be used in conjunction with solar energy and uses a system of air circulation for increased efficiency. [1] A solar heat collector, or solar thermal collector, is used today to capture solar radiation through electromagnetic radiation with the use of solar hot water panels, solar parabolic troughs, or solar towers. Today many ...
The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.
KaXu Solar One is a 100 MW parabolic trough plant. The power station will have a storage capacity of three hours and use molten salt to store heat energy. In the parabolic trough system, the sun's energy is concentrated by parabolically curved, trough-shaped reflectors onto a receiver pipe running along the focal line of the curved surface.

The Solana Generating Station is a solar power plant near Gila Bend, Arizona, about 70 miles (110 km) southwest of Phoenix.It was completed in 2013. When commissioned, it was the largest parabolic trough plant in the world, and the first U.S. solar plant with molten salt thermal energy storage. [3]
GlassPoint's enclosed trough technology encloses lightweight, trough-shaped mirrors with piping in a standard agricultural greenhouse, concentrating the sun's energy to create steam. [1] By using the enclosed trough architecture, GlassPoint claims it can produce emission-free steam for two to three times less than competing concentrated solar ...
Parabolic trough power plants use a curved, mirrored trough which reflects the direct solar radiation onto a glass tube containing a fluid (also called a receiver, absorber or collector) running the length of the trough, positioned at the focal point of the reflectors. The trough is parabolic along one axis and linear in the orthogonal axis.
