From UPSC perspective, the following things are important :
Prelims level: India's Solar Capacity
Why in the News?
A new study by IIT Delhi, published in Environmental Research Letters (November 2024), reveals that air pollution and climate change are undermining solar panel efficiency in India.
Key Findings of the IIT Delhi Study
- Efficiency Loss Forecast:
- Scenario 1 (Moderate climate efforts): Solar panel efficiency is projected to decline by more than 2.3% by 2041-2050.
- Scenario 2 (Weak climate action, strong air pollution control): Efficiency drops by 2.3%, amounting to at least 840 GWh loss annually.
- Primary Causes:
- Solar radiation decline is the biggest factor.
- Temperature increase follows closely, with a 2°C rise in cell temperature predicted by mid-century.
- Wind speed variations have minimal but present impact.
- Kerala and Northeast regions could see higher solar potential due to reduced cloud cover, offering opportunities for future solar investments.
India’s Solar Capacity
- India, is the 5th-largest solar power producer globally.
- India has achieved a significant milestone with a total installed solar capacity of 100.33 GW as of January 31, 2025.
- India’s solar capacity has increased 35 times in the past decade, growing from 2.82 GW in 2014 to 100 GW in 2025.
- PM SuryaGhar Muft Bijli Yojana has been a key driver in promoting rooftop solar, with nearly 9 lakh rooftop installations already completed.
- A record 24.5 GW of solar capacity was added in 2024, more than doubling the installations compared to 2023.
- In 2024, 18.5 GW of utility-scale solar capacity was installed, a nearly 2.8 x increase compared to the previous year.
- Rajasthan, Gujarat, Tamil Nadu, Maharashtra, and Madhya Pradesh are the top-performing states, contributing significantly to India’s solar installations.
- India’s solar module production capacity has surged from 2 GW in 2014 to 60 GW in 2024, establishing the country as a global leader in solar manufacturing.
PYQ:[2020] India has immense potential for solar energy though there are regional variations in its developments. Elaborate. [2018] With reference to solar power production in India, consider the following statements: 1. India is the third largest in the world in the manufacture of silicon wafers used in photovoltaic units. 2. The solar power tariffs are determined by the Solar Energy Corporation of India. 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 |
