Question 1:

Which of the following is a renewable energy source that directly converts sunlight into electricity?

Explanation: Solar energy is a renewable energy source that directly converts sunlight into electricity using photovoltaic (PV) cells. These cells are commonly found in solar panels and can be used to generate electricity for various applications.

Question 2:

Which of the following is the most abundant energy source on Earth?

Explanation: Solar energy is the most abundant energy source on Earth. The Sun continuously provides an enormous amount of energy, and harnessing even a fraction of this energy can meet our energy needs sustainably.

Question 3:

What is the primary component of a photovoltaic (PV) cell?

Explanation: The primary component of a photovoltaic (PV) cell is silicon. Silicon is a semiconductor material that has the ability to absorb sunlight and convert it into electricity.

Question 4:

Which of the following is an advantage of solar energy?

Explanation: Solar energy has several advantages, including its abundance as a renewable resource, zero greenhouse gas emissions during electricity generation, and the ability for modular installation, allowing scalability and flexibility in meeting different energy demands.

Question 5:

Which of the following is a technology that uses mirrors or lenses to concentrate sunlight onto a small area to generate electricity?

Explanation: Solar thermal power is a technology that uses mirrors or lenses to concentrate sunlight onto a small area, typically focusing it on a receiver to generate high-temperature heat. This heat is then used to drive a turbine and generate electricity.
