SOLAR POWER TOWER Meaning and
Definition
-
A solar power tower, also referred to as a solar thermal power tower or a central tower CSP (Concentrated Solar Power) system, is a type of renewable energy technology that harnesses solar radiation to generate electricity. It is a large-scale installation characterized by a tall tower surrounded by an array of sun-tracking mirrors, known as heliostats.
The tower serves as the focal point of the system, typically housing a receiver at the top where concentrated sunlight is collected. The heliostats, controlled by advanced computer systems, follow the sun's trajectory and redirect solar rays onto the receiver, which contains a heat transfer fluid. As the concentrated solar radiation strikes the fluid, it is heated to extremely high temperatures, often reaching over 550 degrees Celsius.
This intense heat is then utilized to create steam, which drives a turbine connected to a generator, ultimately producing electricity. Solar power towers offer the advantage of a higher temperature potential than other solar technologies, as they achieve much higher levels of solar concentration. This translates into more efficient energy conversion and a higher electrical output.
Solar power towers are designed to provide a reliable and sustainable source of electricity, enhancing energy security while reducing greenhouse gas emissions and dependency on fossil fuels. With their ability to generate significant amounts of power, solar power towers play a crucial role in moving towards a cleaner and more sustainable future.
