  • 2. 

    Solar energy is only possible for houses.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Solar energy is not only possible for houses, but it can also be used in various other applications such as commercial buildings, schools, hospitals, and even in large-scale solar farms. Solar energy is a renewable and sustainable source of power that can be harnessed by installing solar panels on rooftops or in open areas with access to sunlight. It is an environmentally friendly option that reduces reliance on fossil fuels and helps in reducing carbon emissions. Therefore, the given statement is incorrect, and solar energy is not limited to houses only.

    Photovoltaic Cells or solar cells are made of

    • Steel

    • Silicon

    • Plastic

    • Concrete

    Correct Answer
    A. Silicon
    Explanation
    Photovoltaic cells, also known as solar cells, are made of silicon. Silicon is a semiconductor material that can convert sunlight directly into electricity through the photovoltaic effect. This is achieved by creating a p-n junction within the silicon material, which allows for the separation of positive and negative charges when exposed to sunlight. Silicon is a widely used material in the production of solar cells due to its abundance, efficiency, and ability to withstand harsh environmental conditions.

    Solar cells can produce energy on a large scale too.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Solar cells are capable of producing energy on a large scale. They can be installed in large solar farms or arrays, where numerous solar panels are connected together to generate electricity. These solar farms can cover vast areas of land and produce a significant amount of energy. Additionally, advancements in solar technology have made it possible to increase the efficiency and capacity of solar cells, further enabling large-scale energy production. Therefore, the statement "Solar cells can produce energy on a large scale too" is true.

  • 5. 

    Photovoltaics is

    • Wind into electricity.

    • The use of geothermal energy.

    • The direct conversion of light into electricity (at the atomic level).

    • None

    Correct Answer
    A. The direct conversion of light into electricity (at the atomic level).
    Explanation
    Photovoltaics refers to the direct conversion of light into electricity at the atomic level. This technology utilizes solar cells made of semiconductor materials that absorb photons from sunlight. When the photons strike the solar cells, they dislodge electrons from their atoms, creating an electric current. This process is known as the photovoltaic effect and is the basis for generating electricity from sunlight. Therefore, the correct answer is the direct conversion of light into electricity (at the atomic level).

    Rate this question:

  • 6. 

    Why are solar panels so widely advocated?

    • Less space

    • Cheapness

    • Because of efficiency

    • They produce clean energy.

    Correct Answer
    A. They produce clean energy.
    Explanation
    Solar panels are widely advocated because they produce clean energy. Unlike traditional energy sources such as fossil fuels, solar energy does not produce harmful emissions or contribute to air pollution. This makes solar panels a sustainable and environmentally-friendly option for generating electricity. Additionally, the use of solar panels helps to reduce dependence on finite resources and promotes the transition towards a more renewable energy future.

    The most common volt system in a Photovoltaic module is

    • 12-volt system

    • 30-volt system

    • 60-volt system

    • 100-volt system

    Correct Answer
    A. 12-volt system
    Explanation
    The most common volt system in a Photovoltaic module is the 12-volt system. This is because it is a standard voltage for many small-scale solar applications, such as charging batteries or powering small electronic devices. It is also commonly used in off-grid solar systems. The 12-volt system is popular due to its simplicity and compatibility with various solar components and appliances.

    Solar panels can only be installed on roofs.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Solar panels can be installed on various surfaces, not just roofs. They can be installed on the ground, on carports, on the sides of buildings, and even on floating platforms in bodies of water. The flexibility of solar panel installation allows for a wide range of options to harness solar energy effectively.

    How much Sunlight falls on the earth?

    • 15 000 TeraWatts

    • 54 000 TeraWatts

    • 89 000 TeraWatts

    • 39 000 TeraWatts

    Correct Answer
    A. 89 000 TeraWatts
    Explanation
    The correct answer is 89,000 TeraWatts. This is the amount of sunlight that falls on the Earth. Sunlight is a crucial source of energy for our planet and is responsible for powering various natural processes such as photosynthesis and the water cycle. It also plays a significant role in determining the Earth's climate and weather patterns.

  • 10. 

    The market average energy conversion ratio for Photovoltaic cells is

    • 12%-18%

    • 20%-30%

    • 40%-50%

    • 100%

    Correct Answer
    A. 12%-18%
    Explanation
    Photovoltaic cells are devices that convert sunlight into electricity. The energy conversion ratio refers to the efficiency of this conversion process, indicating the percentage of sunlight that is successfully converted into usable electrical energy. The given answer, 12%-18%, suggests that the market average energy conversion ratio for Photovoltaic cells falls within this range. This means that, on average, only 12%-18% of the sunlight that hits the cells is converted into electricity, while the remaining percentage is lost as heat or reflected back.
