With reference to technologies for solar power production, consider the following statements :
1. ‘Photovoltaics’ is a technology that generates electricity by direct conversion of light into electricity, while, ‘Solar Thermal’ is a technology that utilizes the Sun’s rays to generate heat which is further used in electricity generation process.
2. ‘Photovoltaics’ generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC).
3. India has manufacturing base for Solar Thermal technology, but not for ‘Photovoltaics’.
Which of the statements given above is/ are correct ?
-
A.
1 only
-
B.
2 and 3 only
-
C.
1, 2 and 3
-
D.
None
Correct Answer:
