What is the primary function of a parabolic trough in CSP systems?

  1. Reflecting sunlight onto a central receiver

  2. Concentrating sunlight onto a linear receiver

  3. Generating electricity directly from sunlight

  4. Storing thermal energy for later use


Correct Option: B
Explanation:

Parabolic troughs use curved mirrors to focus sunlight onto a linear receiver, which contains a heat transfer fluid that absorbs the concentrated solar energy.

In a solar tower system, what is the role of the heliostats?

  1. Reflecting sunlight onto a central receiver

  2. Tracking the sun's movement

  3. Generating electricity directly from sunlight

  4. Storing thermal energy for later use


Correct Option: A
Explanation:

Heliostats are mirrors that track the sun's movement and reflect sunlight onto a central receiver located at the top of a tower.

What type of engine is commonly used in Dish Stirling Systems?

  1. Steam turbine

  2. Gas turbine

  3. Stirling engine

  4. Internal combustion engine


Correct Option: C
Explanation:

Dish Stirling Systems utilize a Stirling engine, which is a type of external combustion engine that converts heat into mechanical energy.

What is the primary advantage of Parabolic Troughs compared to other CSP technologies?

  1. Higher efficiency

  2. Lower cost

  3. Greater land requirement

  4. More complex operation


Correct Option: B
Explanation:

Parabolic Troughs are generally less expensive to construct and maintain compared to other CSP technologies.

Which CSP technology is best suited for large-scale electricity generation?

  1. Parabolic Troughs

  2. Solar Towers

  3. Dish Stirling Systems

  4. All of the above


Correct Option: B
Explanation:

Solar Towers are typically preferred for large-scale electricity generation due to their higher efficiency and ability to store thermal energy.

What is the primary challenge associated with Dish Stirling Systems?

  1. High cost

  2. Low efficiency

  3. Complex operation

  4. Limited scalability


Correct Option: D
Explanation:

Dish Stirling Systems are often limited in terms of scalability compared to other CSP technologies due to their relatively small size and high cost.

Which component of a CSP system is responsible for converting concentrated sunlight into thermal energy?

  1. Receiver

  2. Heliostat

  3. Stirling engine

  4. Turbine


Correct Option: A
Explanation:

The receiver in a CSP system absorbs the concentrated sunlight and converts it into thermal energy, which is then used to generate electricity.

What type of fluid is commonly used as the heat transfer medium in Parabolic Troughs?

  1. Water

  2. Oil

  3. Molten salt

  4. Air


Correct Option: B
Explanation:

Parabolic Troughs typically use oil as the heat transfer fluid due to its high thermal stability and ability to withstand high temperatures.

Which CSP technology utilizes a central receiver to collect concentrated sunlight?

  1. Parabolic Troughs

  2. Solar Towers

  3. Dish Stirling Systems

  4. All of the above


Correct Option: B
Explanation:

Solar Towers use a central receiver located at the top of a tower to collect concentrated sunlight from heliostats.

What is the primary advantage of Solar Towers compared to other CSP technologies?

  1. Higher efficiency

  2. Lower cost

  3. Greater land requirement

  4. More complex operation


Correct Option: A
Explanation:

Solar Towers generally have higher efficiency compared to other CSP technologies due to the use of a central receiver and the ability to store thermal energy.

Which CSP technology is best suited for distributed generation applications?

  1. Parabolic Troughs

  2. Solar Towers

  3. Dish Stirling Systems

  4. All of the above


Correct Option: C
Explanation:

Dish Stirling Systems are often preferred for distributed generation applications due to their modular design and ability to operate independently.

What is the primary challenge associated with Parabolic Troughs?

  1. High cost

  2. Low efficiency

  3. Complex operation

  4. Limited scalability


Correct Option: D
Explanation:

Parabolic Troughs are limited in terms of scalability compared to other CSP technologies due to their linear design and the need for large land areas.

Which component of a CSP system is responsible for converting thermal energy into mechanical energy?

  1. Receiver

  2. Heliostat

  3. Stirling engine

  4. Turbine


Correct Option: D
Explanation:

The turbine in a CSP system converts the thermal energy from the heat transfer fluid into mechanical energy, which is then used to generate electricity.

What type of fluid is commonly used as the heat transfer medium in Solar Towers?

  1. Water

  2. Oil

  3. Molten salt

  4. Air


Correct Option: C
