What is the primary source of energy in Solar Thermal technology?

  1. Wind

  2. Sunlight

  3. Water

  4. Fossil Fuels


Correct Option: B
Explanation:

Solar Thermal technology harnesses the energy from the sun to generate heat or electricity.

Which type of solar thermal collector is commonly used for residential heating and cooling?

  1. Parabolic Trough

  2. Dish Stirling

  3. Evacuated Tube

  4. Solar Chimney


Correct Option: C
Explanation:

Evacuated tube collectors are widely used in residential applications due to their high efficiency and ability to operate in various climates.

What is the role of a heat transfer fluid in a solar thermal system?

  1. To absorb solar radiation

  2. To generate electricity

  3. To transfer heat from the collector to the storage system

  4. To control the temperature of the system


Correct Option: C
Explanation:

The heat transfer fluid circulates through the solar collector, absorbing heat from the sun and transferring it to the storage system for later use.

Which type of solar thermal power plant uses a central receiver to concentrate sunlight onto a single point?

  1. Parabolic Trough

  2. Dish Stirling

  3. Central Receiver

  4. Solar Chimney


Correct Option: C
Explanation:

Central receiver power plants use a large array of mirrors to focus sunlight onto a central receiver, which converts the concentrated solar energy into heat.

What is the primary advantage of solar thermal energy storage systems?

  1. They can generate electricity at night

  2. They can reduce the cost of solar energy

  3. They can increase the efficiency of solar thermal systems

  4. They can provide backup power during grid outages


Correct Option: D
Explanation:

Solar thermal energy storage systems can store excess heat generated during the day and release it during periods of low solar radiation or grid outages.

Which type of solar thermal collector is commonly used for large-scale electricity generation?

  1. Parabolic Trough

  2. Dish Stirling

  3. Evacuated Tube

  4. Solar Chimney


Correct Option: A
Explanation:

Parabolic trough collectors are widely used in large-scale solar thermal power plants due to their high efficiency and ability to generate high temperatures.

What is the primary disadvantage of solar thermal technology?

  1. High installation costs

  2. Intermittency of solar radiation

  3. Low efficiency

  4. Environmental impact


Correct Option: B
Explanation:

The primary disadvantage of solar thermal technology is the intermittency of solar radiation, which means that the availability of solar energy varies depending on the time of day and weather conditions.

Which type of solar thermal collector is commonly used for industrial process heat applications?

  1. Parabolic Trough

  2. Dish Stirling

  3. Flat Plate

  4. Solar Chimney


Correct Option: C
Explanation:

Flat plate collectors are widely used in industrial process heat applications due to their simplicity, low cost, and ability to operate at moderate temperatures.

What is the role of a solar concentrator in a solar thermal system?

  1. To focus sunlight onto a smaller area

  2. To generate electricity

  3. To transfer heat from the collector to the storage system

  4. To control the temperature of the system


Correct Option: A
Explanation:

The solar concentrator focuses sunlight onto a smaller area, increasing the intensity of the solar radiation and improving the efficiency of the system.

Which type of solar thermal power plant uses a series of parabolic mirrors to focus sunlight onto a linear receiver?

  1. Parabolic Trough

  2. Dish Stirling

  3. Central Receiver

  4. Solar Chimney


Correct Option: A
Explanation:

Parabolic trough power plants use a series of parabolic mirrors to focus sunlight onto a linear receiver, which converts the concentrated solar energy into heat.

What is the primary advantage of solar thermal technology over photovoltaic technology?

  1. Higher efficiency

  2. Lower installation costs

  3. Ability to store energy

  4. Lower environmental impact


Correct Option: C
Explanation:

The primary advantage of solar thermal technology over photovoltaic technology is the ability to store energy in the form of heat, which allows for continuous power generation even when the sun is not shining.

Which type of solar thermal collector is commonly used for swimming pool heating?

  1. Parabolic Trough

  2. Dish Stirling

  3. Flat Plate

  4. Solar Chimney


Correct Option: C
Explanation:

Flat plate collectors are widely used for swimming pool heating due to their simplicity, low cost, and ability to operate at moderate temperatures.

What is the primary disadvantage of solar thermal energy storage systems?

  1. High installation costs

  2. Low efficiency

  3. Environmental impact

  4. Limited storage capacity


Correct Option: D
Explanation:

The primary disadvantage of solar thermal energy storage systems is their limited storage capacity, which means that they can only store a limited amount of heat for later use.

Which type of solar thermal power plant uses a series of mirrors to focus sunlight onto a central tower?

  1. Parabolic Trough

  2. Dish Stirling

  3. Central Receiver

  4. Solar Chimney


Correct Option: C
Explanation:

Central receiver power plants use a series of mirrors to focus sunlight onto a central tower, which converts the concentrated solar energy into heat.

What is the role of a thermal energy storage system in a solar thermal power plant?

  1. To store excess heat generated during the day

  2. To generate electricity

  3. To transfer heat from the collector to the storage system

  4. To control the temperature of the system


Correct Option: A
Explanation:

The thermal energy storage system stores excess heat generated during the day and releases it during periods of low solar radiation or high electricity demand.
