Photovoltaic Cells or solar cells are made of
-
Steel
-
Silicon
-
Plastic
-
Concrete
Correct Answer
A. SiliconExplanation
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.Rate this question:

Solar cells can produce energy on a large scale too.
-
True
-
False
Correct Answer
A. TrueExplanation
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.Rate this question:

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 systemExplanation
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.Rate this question:

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.Rate this question:

Solar panels can only be installed on roofs.
-
True
-
False
Correct Answer
A. FalseExplanation
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.Rate this question:

How much Sunlight falls on the earth?
-
15 000 TeraWatts
-
54 000 TeraWatts
-
89 000 TeraWatts
-
39 000 TeraWatts
Correct Answer
A. 89 000 TeraWattsExplanation
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.Rate this question:

Solar energy is only possible for houses.
-
True
-
False
Correct Answer
A. FalseExplanation
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.Rate this question:

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.Rate this question:
