By concentrating the sun’s rays and generating heat, concentrated solar power works. As with steam-powered generators, this heat is subsequently channeled into conventional generators for use in electricity production. Parabolic troughs, power towers, and dish engine systems are the three basic CSP kinds.
Solar collectors reflect and focus light onto a receiver in this type of setup. A pipe, generally filled with oil, runs along the bottom of the trough. To generate power, the heated fluid is passed via a traditional steam generator.
When CSPs are inserted into rows, a collector field is formed. In order to maximize efficiency, these CSPs can be moved around freely to follow the sun’s path. When the sun isn’t shining, parabolic troughs rely on fossil fuels to power their systems.
Heliostats, which follow the sun and reflect concentrated beams onto a reflector at the base of the pole, are used in power towers. A turbine generator is then powered by the heat of a transfer fluid, such as oil.
Because molten nitrate salt is a better heat transfer medium than oil, some models employ it.
Rather than using coal or gas, these systems use sunlight to generate power. The solar concentrator and the power conversion unit are the system’s two most important components.
By collecting and concentrating sunlight, the solar concentrator may power a receiver. Reflective glass on the concentrator’s surface reflects about 92% of the sun’s rays.
