THE SEAMLESS LINK
India's burgeoning solar photovoltaic (PV) manufacturing sector faces a critical imbalance, with upstream segments like polysilicon, ingot, and wafer production lagging significantly behind downstream module assembly. This disparity necessitates substantial imports to meet domestic demand and exposes the nation to global price volatility, prompting discussions on a new government intervention. The Ministry of New and Renewable Energy (MNRE) is actively engaging with the Ministry of Finance to explore a dedicated capital expenditure (capex) subsidy, distinct from the existing Production Linked Incentive (PLI) scheme, designed to invigorate these foundational manufacturing stages. MNRE Secretary Santosh Kumar Sarangi highlighted the need for "a slight tweak in the way in which support could be provided to these kinds of industries" to overcome persistent challenges.
The Upstream Bottleneck: Capacity Gaps and Cost Pressures
Despite substantial growth in solar module manufacturing capacity, reaching approximately 121.7 GW as per the Approved List of Models and Manufacturers (ALMM), India's upstream capabilities remain critically underdeveloped. The country's installed ingot and wafer manufacturing capacity is only around 2 GW, while there is no commercial production of polysilicon. This gap forces reliance on imports. For fiscal year 2025 (FY25), imports of solar PV cells amounted to approximately $1,641 million, wafers to about $156 million, and polysilicon to roughly $0.03 million. These upstream segments are characterized by high capital intensity and are subject to aggressive pricing from international competitors, primarily China, making domestic establishment and competitiveness difficult. Polysilicon refining, in particular, is an extremely electricity-intensive process requiring access to low-cost power, adding another layer of complexity for potential domestic producers.
PLI Scheme's Mixed Results in Foundational Segments
The existing PLI scheme for solar PV modules, backed by a total outlay of ₹24,000 crore, was intended to foster integrated manufacturing from raw materials to finished modules. However, its impact on upstream segments has been notably limited. A joint report by the Institute for Energy Economics and Financial Analysis (IEEFA) and JMK Research, released in December 2025, revealed significant implementation and execution gaps in these foundational areas. The report indicated that operationalisation of awarded facilities under the scheme has lagged, with capacity achievement rates standing at only 10% for wafer-ingot manufacturing and 14% for polysilicon manufacturing. This contrasts sharply with the progress in downstream module assembly, which saw a 59% achievement rate, demonstrating that while downstream expansion is progressing, the crucial upstream supply chain remains a bottleneck.
Rationale for a Dedicated Capex Subsidy
The proposed new subsidy aims to directly tackle the financial barriers hindering upstream capacity expansion. By offering direct capital expenditure support, the government intends to de-risk significant investments required for polysilicon and ingot-wafer projects. This could potentially revive projects sanctioned under the PLI scheme that failed to materialize for various reasons. This strategic shift acknowledges that the PLI model, while effective for some segments, may not adequately address the unique, capital-intensive, and power-dependent nature of upstream solar PV manufacturing. The focus is on creating a more robust and self-sufficient domestic supply chain, reducing vulnerability to global market fluctuations and geopolitical factors.
Outlook for Domestic Upstream Solar Manufacturing
The introduction of a dedicated capex subsidy represents a significant policy push to strengthen India's position in the global solar value chain. Its success hinges on effectively incentivizing investment in polysilicon and wafer production, overcoming the cost disadvantages compared to established international players. By developing domestic upstream capabilities, India aims to enhance its energy security, create high-value manufacturing jobs, and further its 'Make in India' agenda. This policy shift could alter the competitive dynamics within the sector, potentially drawing more investment into these previously underdeveloped areas and reducing long-term import reliance, thereby creating a more resilient and integrated domestic solar industry.
