Backgrounder: India’s solar growth after PM Surya Sarovar
UPSC has already asked about this. Read the story with these questions in mind.
A PIB backgrounder of 2 August 2026 reviews India’s solar growth after the Cabinet approved the PM Surya Sarovar Yojana on 31 July. The scheme backs 5,000 MW of floating solar with storage, at ₹5,070 crore. Solar capacity has grown from about 3 GW in 2014 to 162.15 GW by 30 June 2026, the largest share of renewables.

India’s solar growth and PM Surya Sarovar Yojana: what happened?
Solar has gone from a small share of India’s power mix to the largest part of its renewable capacity in about a decade. The new scheme tackles two problems at once: land, by putting panels on water, and evening peaks, by adding storage. The backgrounder groups the rest of the story into targets, demand, low tariffs, infrastructure and manufacturing.
- PM-SSY uses existing reservoirs and industrial ponds, easing pressure on land.
- NISE estimates floating solar potential of about 102.18 GWp across reservoirs and inland water bodies.
- PM-SSY should cut about 10 million tonnes of CO2 a year and create 16,000 to 17,000 full-time equivalent jobs.
- It will raise floating solar capacity by 5,000 MW from around 700 MW; all States and UTs are eligible.
- India added 37 GW of solar in 2025, passing the United States in annual additions.
What built the solar boom?
| Pillar | What it includes |
|---|---|
| Vision | Panchamrit at COP26: 500 GW non-fossil by 2030, net zero by 2070; Mission LiFE |
| Demand | National Solar Mission (2010); RPOs (35.95% for 2026-27); PM Surya Ghar; PM-KUSUM |
| Lower costs | e-Reverse Auctions via SECI; tariff from about ₹18 a unit (2010) to ₹2.44 (Bhadla, 2017) |
| Infrastructure | Solar Parks Scheme: 54 parks, 39,188 MW sanctioned (Feb 2026); Green Energy Corridor |
| Manufacturing | PLI for modules (₹4,500 crore in 2021, plus ₹19,500 crore in 2022); ALMM (2019) |
How are households and farmers involved?
- PM Surya Ghar (13 February 2024, ₹75,021 crore): over 43 lakh households solarised as of June 2026.
- PM-KUSUM (2019): about 11.49 lakh off-grid solar pumps, over 15.89 lakh pumps under feeder solarisation, about 1,726 MW on farmers’ land.
- In FY 2025-26, distributed solar gave 16.3 GW, or 36%, of the 44.61 GW added: 7.6 GW from PM-KUSUM and 8.7 GW from rooftops.
What do the key numbers say?
| Item | Figure |
|---|---|
| Large solar projects | 118.79 GW |
| Grid-connected rooftop | 27.88 GW |
| Module manufacturing capacity | 2.3 GW (2014) to about 172 GW (31 March 2026) |
| Non-fossil capacity | 283.46 GW, incl. 274.68 GW renewable |
| Record non-fossil addition | 55.29 GW in a year |
| Utility solar LCOE (2025) | USD 35 per MWh vs global USD 44 |
How will PM-SSY work?
- NISE maps floating solar potential
- States pick reservoirs and industrial ponds
- FSPV plants with co-located storage built
- Storage helps States meet peak demand
- Floating solar grows from about 700 MW by 5,000 MW
Why does India’s solar growth and PM Surya Sarovar Yojana matter?
| Angle | What to note |
|---|---|
| Land | Floating panels avoid using scarce land. |
| Grid | Storage helps manage peak demand and reliability. |
| Climate | About 10 million tonnes of CO2 avoided a year. |
| Industry | Demand for domestic floats, cells, modules and storage. |
| Global role | ISA, co-founded with France in 2015, and OSOWOG. |
What are the challenges in India’s solar growth and PM Surya Sarovar Yojana?
- Solar output peaks at midday, so storage and transmission must keep pace.
- Floating solar is still small, around 700 MW today.
- Manufacturing depends on keeping quality and costs in line through ALMM and PLI.
- Rooftop and farm schemes need DISCOM cooperation to scale.
What should be done next on India’s solar growth and PM Surya Sarovar Yojana?
- Roll out PM-SSY in all States from FY 2026-27.
- Build Green Energy Corridor lines for about 44 GW more.
- Deepen domestic manufacturing across the value chain.
- Keep RPO targets on track to 2029-30.
