Solar Concentrated Power
Introduction to Concentrated Solar Power
Concentrated Solar Power (CSP) is a technology that harnesses the power of sunlight to generate electricity. It uses mirrors or lenses to concentrate sunlight onto a receiver, which converts the solar energy into heat. The heat is then used to drive a steam turbine or heat engine, producing electricity. CSP systems offer a renewable and sustainable approach to large-scale power generation.
Question 1: What is Concentrated Solar Power (CSP)?
a) A technology that uses wind energy to generate electricity
b) A technology that uses sunlight to generate electricity
c) A technology that uses fossil fuels to generate electricity
Answer: b) A technology that uses sunlight to generate electricity
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.
Question 2: What are the main components of Concentrated Solar Power systems?
a) Solar Panels, Batteries, Inverters

c) Wind Turbines, Generators, Transformers
Answer: b) Solar Collectors, Receiver, Heat Transfer System
Working Principle of Concentrated Solar Power
The working principle of Concentrated Solar Power can be summarized as follows:
- Solar Concentration: Mirrors or lenses focus sunlight onto a small area, intensifying the solar energy.
- Heat Generation: The concentrated sunlight heats up a receiver, which contains a working fluid.
- Heat Transfer: The heat is transferred from the receiver to a heat transfer fluid, such as molten salt.
- Energy Conversion: The heat transfer fluid generates steam, which drives a turbine or heat engine to produce electricity.
- Power Distribution: The electricity generated is transmitted through a power grid to supply homes and businesses.
Question 3: What is the first step in the working principle of Concentrated Solar Power?
a) Solar concentration
b) Heat transfer
c) Power distribution
Answer: a) Solar concentration
