India’s proposed polysilicon manufacturing scheme signals a decisive change in the country’s solar strategy: from expanding the production of finished modules and cells to building the upstream industrial capacity that makes them possible. The Ministry of New and Renewable Energy is working on an incentive programme, with an initial proposal supporting more than 10 GW of capacity and a later target of at least 30 GW by 2030.
The proposal matters because India’s solar manufacturing base remains uneven. The country has built substantial capacity in modules and is expanding cell production, but it continues to depend heavily on imports for polysilicon, the material at the beginning of the manufacturing chain. That gap leaves the domestic industry exposed to overseas supply disruptions and sharp price changes, according to the report by NDTV Business.
Polysilicon is converted into ingots and wafers. Wafers are then used to make solar cells, which are assembled into modules. A module may be the most visible part of a solar project, but it is the final stage of a much longer industrial process. India’s policy focus has so far produced stronger capacity at that downstream end than at the upstream stages.
According to figures attributed to the renewable energy ministry, India has more than 213 GW of solar module manufacturing capacity and around 32 GW of cell capacity. The contrast with the proposed polysilicon target is important. It shows that the government is not simply trying to increase the number of factories making panels; it is attempting to connect different stages of the chain within the country.
That approach reflects a structural weakness in solar manufacturing. Capacity at one stage does not automatically create a complete domestic ecosystem. If polysilicon, ingots or wafers still have to be imported, Indian cell and module manufacturers remain dependent on external suppliers for critical inputs. A disruption at the upstream end can therefore affect production further down the chain, even when domestic module capacity is available.
The dependence on China is central to the policy discussion. The report states that India currently relies heavily on China for polysilicon imports. Reducing that dependence is one stated objective of the proposed scheme, alongside the broader goal of creating a more integrated and resilient solar manufacturing system.
However, the government has not yet announced the final structure of the programme. The incentive rates, eligibility conditions and other operating details remain undecided in the supplied material. That means the target is a policy direction rather than an operational programme. The difference is significant: a capacity ambition becomes meaningful only when the rules, funding support, project pipeline and implementation responsibilities are clear.
The proposal is expected to follow the production-linked incentive model. Under that approach, support is linked to production and performance rather than being provided only for setting up manufacturing facilities. The design of the proposed polysilicon scheme will therefore determine whether it creates commercially viable capacity or simply encourages announcements of planned investment.
The scale of investment is another reason the upstream push will be difficult. MNRE Secretary Santosh Kumar Sarangi said that setting up polysilicon plants along with metallurgical-grade silicon could require investment of around Rs 850 crore per GW. At that indicative level, building 30 GW of capacity would represent a large industrial investment, although the final cost and financing structure would depend on the technology, plant configuration and supporting infrastructure.
The proposed polysilicon programme is also linked to a separate ambition for ingot and wafer manufacturing. India is targeting at least 80 GW of domestic ingot and wafer capacity by June 2028. Taken together, the targets suggest a strategy that moves backwards through the manufacturing chain: from modules to cells, then to wafers, ingots and polysilicon.
This sequencing is important for understanding the government’s industrial policy. A country can expand its renewable-energy deployment while remaining dependent on imported equipment and materials. It can also build module factories without establishing the chemical, materials and energy systems required by upstream manufacturing. The current proposal attempts to address that distinction by treating solar manufacturing as an industrial network rather than a single factory category.
The economics of that network remain unresolved. Vinay Thadani, Director and CEO of GREW Solar, told NDTV that India had progressed in modules and cells but still faced a distinct gap in polysilicon and wafers. He supported the proposed incentive scheme but said domestic manufacturing should not focus only on import reduction. In his view, long-term cost competitiveness would also require scale, technology, operational effectiveness and competitive energy procurement.
That qualification exposes the central implementation challenge. Import substitution can provide a reason to build capacity, but it does not by itself guarantee that domestic output will be cost-effective. Polysilicon production is an upstream industrial activity requiring substantial investment and reliable operating conditions. The success of the scheme will depend not only on whether plants are commissioned, but also on whether they can produce at a scale and cost that supports the rest of the domestic chain.
Energy procurement is particularly relevant to the issue as described by the industry representative, although the supplied report does not provide a detailed estimate of energy requirements or production costs. The government’s final policy will therefore need to be assessed on the evidence it provides about capacity utilisation, technology standards, production milestones and the relationship between incentives and actual output.
Industry plans indicate that private investment may develop alongside government support. Thadani said GREW Solar was planning to establish 8 GW of ingot and wafer manufacturing capacity. That proposed capacity would sit below the government’s wider target of at least 80 GW by June 2028, but it illustrates the type of company-level expansion the policy is intended to encourage.
The numbers also reveal the gap between announced ambition and current industrial depth. More than 213 GW of module capacity and around 32 GW of cell capacity represent a substantial downstream base, while the proposed polysilicon capacity target remains a future objective. The policy question is not simply whether India can manufacture more solar panels. It is whether capacity across the different stages can grow in a coordinated way.
That coordination has institutional consequences. The ministry must determine the incentive framework, while manufacturers will have to commit capital, select technology and build operating capacity. The supply chain will also require reliable movement of materials between stages. The supplied report does not establish how these responsibilities will be divided or how the proposed scheme will interact with existing manufacturing incentives.
The timing of the targets adds another layer of complexity. The government is considering at least 30 GW of polysilicon capacity by 2030 and at least 80 GW of ingot and wafer capacity by June 2028. These are different milestones for connected parts of the same chain. If upstream and downstream capacity do not advance in step, manufacturers could continue to depend on imports even as domestic factories are added.
The proposed scheme therefore marks a shift in the definition of solar self-reliance. Producing modules in India is one measure of manufacturing capability, but it does not capture the country’s exposure to imported raw materials and intermediate products. A more complete measure would consider how much of the chain—from polysilicon to modules—can operate within the domestic industrial system.
The evidence currently supports two conclusions. First, India has developed considerable capacity in modules and is expanding cells. Second, the upstream parts of the chain remain a material gap, particularly polysilicon and wafers. What remains uncertain is whether the proposed incentives will create competitive, operating capacity at the scale announced. The next decisive developments will be the final scheme, its eligibility and incentive terms, and evidence of actual investment and production against the 2028 and 2030 targets.
