🔆 Solar Energy: India’s Sunrise Sector
📚 GS3 – Geography | Environment | Energy Transition
📍What is Solar Energy?
✅ Photovoltaic (PV): Uses silicon-based solar cells to convert sunlight into DC electricity, later inverted to AC.
✅ Concentrated Solar Power (CSP): Uses mirrors/lenses to generate heat → steam → turbines.
📍India’s Status (2025)
✅ Installed capacity: 100.33 GW (from 2.82 GW in 2014).
✅ 84.10 GW under implementation + 47.49 GW tendered.
✅ Contributes 47% of India’s total renewable energy capacity.
✅ Leading states: Rajasthan (Bhadla Solar Park), Gujarat, Karnataka.
📍Advantages
✅ Zero emissions & water saving → ideal for arid regions.
✅ Cost-effective → PV cost fell 90% in a decade.
✅ Job creation in installation, maintenance, and R&D.
✅ Energy security → reduces fossil fuel imports.
✅ Decentralized rooftop solar → resilient against grid failures.
📍Challenges
✅ Sunlight dependency → no power at night/cloudy days.
✅ Storage costs → batteries still expensive.
✅ Land & ecological footprint of large solar farms.
✅ Manufacturing & recycling challenges for solar panels.
📍Emerging Trends
✅ Agri-voltaics: Solar + crops on same land.
✅ BIPV: Building-integrated photovoltaics (roofs, facades).
✅ Floatovoltaics: Solar panels on reservoirs, reducing evaporation.
✅ Perovskite cells: Next-gen high efficiency materials.
📍Key Government Schemes
✅ National Solar Mission (2010): Flagship solar push.
✅ PM-KUSUM (2019): Solar pumps + decentralised rural energy (target ~35 lakh pumps).
✅ PM Surya Ghar Muft Bijli Yojana (2024): Rooftop solar for 1 crore homes by 2027.
✅ Solar Park Scheme: Plug-and-play infra for developers.
✅ PLI Scheme: Boosts domestic solar module manufacturing.
📍Conclusion
✅ With a target of 500 GW non-fossil capacity by 2030, solar energy is central to India’s energy security, climate commitments, and green jobs. Innovation + storage + policy support will make India a global solar leader.
