Context:
The Ministry of New and Renewable Energy (MNRE) and the Ministry of Finance are discussing a capital expenditure (capex) subsidy scheme to strengthen India’s upstream solar photovoltaic (PV) manufacturing, aiming to reduce dependence on imports, especially from China.
Key Highlights:
- Proposed Government Initiative
- New capex subsidy for:
- Polysilicon refining
- Ingot manufacturing
- Wafer production
- Targets projects sanctioned under the PLI scheme that have not yet taken off.
- Existing Capacity Gaps
- Solar PV cell manufacturing capacity: ~27 GW.
- Ingot & wafer capacity: ~2 GW (major bottleneck).
- Upstream progress slower than downstream module assembly.
- Import Dependence (FY25)
- PV Cells: $1,641 million
- Wafers: $156 million
- Polysilicon: $0.03 million
- China dominates high-efficiency solar inputs.
- PLI Scheme Background
- Launched in March 2021.
- Target: 65 GW per annum integrated solar PV manufacturing capacity.
- Total outlay: ₹24,000 crore.
- As of June 2025, only ~29% operational capacity achieved.
- Structural Challenges
- Polysilicon production is highly electricity-intensive.
- Need for low-cost renewable power for competitiveness.
- Pricing pressures due to Chinese economies of scale.
Relevant Prelims Points:
- Polysilicon: High-purity silicon used to manufacture solar cells.
- Ingot: Block of purified silicon cast for wafer slicing.
- Wafer: Thin semiconductor slice used in solar cell fabrication.
- Solar PV Module: Assembly of solar cells generating electricity.
- Production Linked Incentive (PLI) Scheme:
- Incentive linked to incremental production.
- Aims to boost domestic manufacturing.
- Solar energy under National Solar Mission (part of NAPCC).
Relevant Mains Points:
GS Paper 3 – Economy
- Strengthening upstream capacity improves value addition within India.
- Reduces trade deficit in renewable technology imports.
- Enhances supply chain resilience amid global geopolitical tensions.
GS Paper 3 – Science & Technology

- Enhances India’s climate leadership credibility.
Way Forward:
- Provide stable policy signals and long-term tariff certainty.
- Ensure access to affordable renewable power for polysilicon plants.
- Promote R&D and technology partnerships.
- Integrate with export strategy for Global South markets.
