What is the primary principle behind Concentrated Solar Power (CSP) technology?

  1. Harnessing sunlight to generate electricity

  2. Using solar panels to convert light energy into electricity

  3. Concentrating sunlight to produce high temperatures for industrial processes

  4. Storing solar energy in batteries for later use


Correct Option: C
Explanation:

CSP technology involves concentrating sunlight using mirrors or lenses to generate high temperatures, which can be used to drive turbines or produce steam for electricity generation.

Which type of CSP system uses a central receiver to collect and concentrate sunlight?

  1. Parabolic Trough

  2. Dish Stirling

  3. Central Receiver System

  4. Linear Fresnel Reflector


Correct Option: C
Explanation:

In a Central Receiver System, a large number of mirrors (heliostats) are used to focus sunlight onto a central receiver located at the top of a tower.

What is the primary advantage of using parabolic troughs in CSP systems?

  1. High efficiency in converting sunlight to electricity

  2. Ability to operate at high temperatures

  3. Low cost and ease of maintenance

  4. Suitability for large-scale power generation
