Prelims Pointers
- NESL is linked to air pollution monitoring
- Solar calibration facility ensures international PV measurement standards
- CSIR NPL is India’s national metrology institute
- Only five countries globally have national primary solar calibration facilities
| [2014] With reference to technology 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 only (d) None of the above |
