The overall efficiency of the power conversion system is composed of the efficiency of the solar collectors (with parabolic troughs, max ~75%), the efficiency of the heat engine (~35%). Minus field losses, the typical average overall efficiency of solar trough thermal plants is around 15-20%.
These troughs can track the Sun around one axis, typically oriented north–south to ensure the highest possible efficiency. The fluid flows through this tube and absorbs heat from the concentrated solar energy. Similar to a parabolic trough is a linear Fresnel system.
The technology cases presented above show that a for parabolic trough solar thermal electric technologies 7 shows the relative impacts of the various cost system's levelized cost of energy. It is significant require any significant technology development.- technology areas if parabolic troughs are to be y significant market penetration.
Most of the commercially available PTC solar power plants use parabolic concentrators of the aperture with 5.77 m (Eurotrough). However, recently large aperture PTC such as SkyFuel trough of 6 m and Ultimatetrough 7.5 m is under development for reducing the cost of the solar field.
The traditional parabolic trough solar concentrator is widely used in the solar collection field, especially in a solar thermal power plant, because it has the most mature technology. Under the condition of accuracy tracking by a precise mechanism, it can achieve heat at a temperature higher than 400°C.
One drawback, however, is that a direct steam system creates many engineering challenges due to both the higher temperature in the collector field and the need to manage a water/steam system under changing heat input conditions. Consequently, direct steam production is not commonly used in commercial solar trough power plants.
