Question
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 (A(c), while Solar Thermal generates Direct Current (D(c).
3. India has manufacturing base for Solar Thermal technology, but not for Photovoltaics.

Explanation:
Statement 1 is correct: '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 the electricity generation process.
Statement 2 is incorrect because both photovoltaics and solar thermal can generate either alternating current (AC) or direct current (DC), depending on the specific design and application.
Statement 3 is incorrect. India has manufacturing capabilities for both Solar Thermal and Photovoltaics technologies. India has a significant presence in the production of solar cells, modules, and other components used in photovoltaic systems.
