Question

Q. With reference to solar energy, consider the following statements:

Which of the statements given above is/are correct?

• A. 1 only
• B. 2 only
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

The correct option is C Both 1 and 2

Explanation:

Statement 1 is correct: Solar photovoltaic technology directly converts sunlight into electricity without moving parts (rotation of generator armature), using a technology based on the photovoltaic effect. It uses semiconductors made of germanium and silicon to convert sunlight into electricity. After expiring these photovoltaic cells become electronic waste.

Statement 2 is correct: Concentrating solar power technology uses mirrors to concentrate (focus) the sun's light energy and convert it into heat to create steam to drive a turbine that generates electrical power.
