Solar Thermal Power Plants
Linear concentrating systems collect the sun''s energy using long, rectangular, curved (U-shaped) mirrors. The mirrors focus sunlight onto receivers (tubes) that run the length of the mirrors.

Figure 1 shows the fundamental principle of solar thermal power generation, which is comprised of four main sub-systems, namely solar collector field, solar receiver, storage and/or back up...
This overview will focus on the central receiver, or “power tower” concentrating solar power plant design, in which a field of mirrors - heliostats, track the sun throughout the day and year to reflect solar
Solar thermal-electric power systems collect and concentrate sunlight to produce the high temperatures needed to generate electricity. All solar thermal power systems have solar energy
PTCs use a long, trough-shaped mirror to focus sunlight on a pipe receiver in the center, which is attached to the trough-shaped mirror and moves with it. In contrast, LFRs utilize many long mirrors
A solar thermal power plant can be divided into three sub-systems, namely solar energy collection sub-system, thermal energy extraction and storage sub-system, and power generation sub
The plant has a nominal capacity of 100MW and the power block has an efficiency of 0.358. The solar field is composed of 156 loops, each of them with 4 PTC in series.
In power tower concentrating solar power systems, a large number of flat, sun-tracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower.
A brief video showing how concentrating solar power works (using a parabolic trough system as an example) is available from the Department of Energy Solar Energy Technologies Web site.
Electricity is generated when the concentrated light is converted to heat (solar thermal energy), which drives a heat engine, either Stirling engine or a steam turbine as in fossil thermal power stations, via
