With reference to technologies for solar power production, consider the following statements:
- ‘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.
- Photovoltaics generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC).
- India has a manufacturing base for Solar Thermal technology, but not for Photovoltaics.
Which of the statements given above is/are correct?
Detailed Explanation:
✅ Statement 1 – Correct: Photovoltaics (PV) directly converts light into electricity using semiconductor materials, while Solar Thermal uses concentrated sunlight to generate heat, which drives turbines for electricity generation.
❌ Statement 2 – Incorrect: Photovoltaic systems generate Direct Current (DC), which is converted to AC through inverters. Solar Thermal systems produce AC electricity directly through conventional turbine-generator systems.
❌ Statement 3 – Incorrect: India has a strong manufacturing base for Photovoltaics (companies like Adani Solar, Vikram Solar, Tata Power Solar), while Solar Thermal manufacturing is limited to small-scale applications like water heaters.
