Solar Concentrated Power

Components of Concentrated Solar Power Systems

Concentrated Solar Power systems typically consist of the following components:

• Solar Collectors: Mirrors or lenses that concentrate sunlight onto a receiver.
• Receiver: Absorbs concentrated sunlight and converts it into heat.
• Heat Transfer System: Transfers the heat from the receiver to a working fluid, such as molten salt.
• Power Conversion: The heat is used to generate steam, which drives a turbine or heat engine to produce electricity.
• Energy Storage: Some CSP systems incorporate thermal energy storage to provide electricity even when the sun is not shining.

Working Principle of Concentrated Solar Power

The working principle of Concentrated Solar Power can be summarized as follows:

1. Solar Concentration: Mirrors or lenses focus sunlight onto a small area, intensifying the solar energy.
2. Heat Generation: The concentrated sunlight heats up a receiver, which contains a working fluid.
3. Heat Transfer: The heat is transferred from the receiver to a heat transfer fluid, such as molten salt.
4. Energy Conversion: The heat transfer fluid generates steam, which drives a turbine or heat engine to produce electricity.
5. Power Distribution: The electricity generated is transmitted through a power grid to supply homes and businesses.
