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]
A solar thermal collector collects heat by absorbing sunlight. 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.

A cost/performance comparison between power tower and parabolic trough concentrators was made by the NREL which estimated that by 2020 electricity could be produced from power towers for 5.47 ¢/kWh and for 6.21 ¢/kWh from parabolic troughs. The capacity factor for power towers was estimated to be 72.9% and 56.2% for parabolic troughs. [46]
In Kuwait a MSF facility uses parabolic trough collectors to provide solar thermal energy to produce 100 m 3 of fresh water a day. [8] And in Northern China an experimental, automatic, unmanned operation uses 80 m 2 of vacuum tube solar collectors coupled with a 1 kW wind turbine (to drive several small pumps) to produce 0.8 m 3 /day.

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]
The solar field comprises loops of parabolic trough solar collector assemblies which will collect the heat from the sun. The solar collectors will be capable of heating the heat transfer fluid up to 393 °C. The power block comprises a solar steam generator and a steam turbine delivering 50 MW (net).

The collectors installed have a combined surface area of 51 hectares (equal to 70 soccer fields); it occupies about 200 ha of land. [7] Andasol is the first parabolic trough power plant in Europe. Because of the high altitude (1,100 m) and the semi-arid climate, the site has exceptionally high annual direct insolation of 2,200 kWh/m 2 per year. [7]
Sketch of a Parabolic Trough Collector. The installation uses parabolic trough, solar thermal technology along with natural gas to generate electricity. About 90% of the electricity is produced by the sunlight. [citation needed] Natural gas is only used when the solar power is insufficient to meet the demand from Southern California Edison, the ...
