The primary mechanism by which solar photovoltaic (PV) cells convert sunlight into electricity is:

  1. Photovoltaic Effect

  2. Photoluminescence

  3. Photoconductivity

  4. Photochromism

Show answer
Correct Option: A
Explanation:

The photovoltaic effect refers to the generation of electrical current when light falls on a semiconductor material, causing electrons to be excited and creating a flow of charge.

In a solar thermal collector, the primary purpose of the absorber plate is to:

  1. Generate electricity directly from sunlight

  2. Convert sunlight into heat energy

  3. Store thermal energy for later use

  4. Reflect sunlight away from the collector

Show answer
Correct Option: B
Explanation:

The absorber plate in a solar thermal collector is designed to efficiently absorb sunlight and convert it into thermal energy, which can then be used for heating purposes.

Which of the following is a key advantage of solar water heaters over conventional water heaters?

  1. Lower operating costs

  2. Reduced maintenance requirements

  3. Increased energy efficiency

  4. All of the above

Show answer
Correct Option: D
Explanation:

Solar water heaters offer lower operating costs, reduced maintenance requirements, and increased energy efficiency compared to conventional water heaters.

The primary application of solar energy in space exploration is to:

  1. Power satellites

  2. Heat spacecraft interiors

  3. Generate oxygen for life support

  4. Provide propulsion for spacecraft

Show answer
Correct Option: A
Explanation:

Solar energy is primarily used in space exploration to power satellites, providing electricity for various spacecraft systems and instruments.

Which of the following is NOT a potential environmental benefit of utilizing solar energy?

  1. Reduced greenhouse gas emissions

  2. Improved air quality

  3. Increased water pollution

  4. Conservation of fossil fuels

Show answer
Correct Option: C
Explanation:

Solar energy does not contribute to water pollution, unlike some other energy sources.

The primary challenge associated with the large-scale adoption of solar energy is:

  1. High installation costs

  2. Intermittency of solar power

  3. Limited availability of sunlight

  4. All of the above

Show answer
Correct Option: D
Explanation:

Solar energy faces challenges related to high installation costs, the intermittent nature of solar power, and the limited availability of sunlight in certain regions.

Which of the following is a promising technology for storing solar energy for use at night or during periods of low sunlight?

  1. Pumped-storage hydroelectricity

  2. Battery energy storage systems

  3. Compressed air energy storage

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the mentioned technologies offer potential solutions for storing solar energy and making it available when needed.

The term "net metering" in the context of solar energy refers to:

  1. The process of measuring the amount of solar energy generated by a system

  2. A billing mechanism that allows solar energy system owners to sell excess electricity back to the grid

  3. A method for tracking the performance of solar energy systems

  4. A regulation that requires utilities to purchase solar energy from homeowners

Show answer
Correct Option: B
Explanation:

Net metering is a billing mechanism that allows solar energy system owners to sell excess electricity generated by their systems back to the grid, typically at a predetermined rate.

Which of the following is a key factor to consider when choosing the location for a solar energy project?

  1. Availability of sunlight

  2. Proximity to load centers

  3. Land availability and cost

  4. All of the above

Show answer
Correct Option: D
Explanation:

When selecting a location for a solar energy project, it is important to consider factors such as the availability of sunlight, proximity to load centers, and land availability and cost.

The primary purpose of a solar inverter in a solar photovoltaic (PV) system is to:

  1. Convert direct current (DC) electricity generated by the PV panels into alternating current (AC) electricity

  2. Increase the voltage of the electricity generated by the PV panels

  3. Store excess electricity generated by the PV panels

  4. Track the position of the sun and adjust the angle of the PV panels

Show answer
Correct Option: A
Explanation:

The primary function of a solar inverter is to convert the direct current (DC) electricity generated by the PV panels into alternating current (AC) electricity, which is compatible with the electrical grid and most appliances.

Which of the following is NOT a type of solar thermal collector?

  1. Flat-plate collectors

  2. Evacuated tube collectors

  3. Parabolic trough collectors

  4. Wind turbines

Show answer
Correct Option: D
Explanation:

Wind turbines are not a type of solar thermal collector. They utilize the kinetic energy of wind to generate electricity, while solar thermal collectors harness solar energy to generate heat.

The primary advantage of solar energy over fossil fuels is its:

  1. Renewability and sustainability

  2. Lower cost

  3. Higher efficiency

  4. All of the above

Show answer
Correct Option: A
Explanation:

The primary advantage of solar energy over fossil fuels is its renewability and sustainability. Solar energy is a clean and inexhaustible source of energy that does not emit greenhouse gases or contribute to air pollution.

Which of the following is a potential application of solar energy in agriculture?

  1. Powering irrigation systems

  2. Heating greenhouses

  3. Drying crops

  4. All of the above

Show answer
Correct Option: D
Explanation:

Solar energy can be used in agriculture for powering irrigation systems, heating greenhouses, drying crops, and other applications.

The term "solar constant" refers to:

  1. The amount of solar energy reaching the Earth's surface

  2. The intensity of solar radiation at the Earth's orbit

  3. The average amount of solar energy received by the Earth over a year

  4. The temperature of the Sun's surface

Show answer
Correct Option: B
Explanation:

The solar constant refers to the intensity of solar radiation at the Earth's orbit, which is approximately 1361 watts per square meter.
