A parabolic trough is a special type of solar concentrator that has a parabolic cross section (it is parabolic in two dimensions) but is linear in the third dimension. The result is that the parabolic shape is extended linearly to make a long reflector. The shape of the reflector causes sunlight to be concentrated along a line at the focus of the parabola, a line that runs along the length of
As a result, evacuated tube collectors can operate at temperatures above 100ºC, compared with about 100ºC for flat plate collectors. The principle of operation is similar to a flat plate collector in that solar radiation (both direct and diffuse) enters through the glass tube and is absorbed by the absorber plate, which transfers the heat
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.
