Why India's Solar PLI Success Story Still Can't Find 42 GW of Buyers

Why India's Solar PLI Success Story Still Can't Find 42 GW of Buyers The Production-Linked

Incentive scheme for solar PV modules worked exactly as designed - for the segment it was designed for. Cell and module assembly is capital-light, has a fast construction-to-output timeline and pays back an output-linked subsidy quickly because production starts within a year or two of investment.

That is precisely why India now has enough announced module capacity that 42 GW of it - including 18 GW of solar-only projects - cannot find a buyer willing to sign an offtake agreement.

The Investor Whose Numbers Don't Work Picture the

specific decision a project developer actually has to make: sign a 25-year power purchase agreement at a price that has to cover the module cost today. If that module was assembled domestically using imported polysilicon - subject to import duties and shipping costs that Chinese-integrated competitors don't carry - the all-in module price often can't beat what a fully-imported Chinese panel costs, even after India's import tariffs.

The developer doesn't sign. Multiply that decision across enough projects and you get 42 GW sitting unbuilt, not because India lacks manufacturing capacity, but because that capacity's cost structure can't clear the market price.

Why the Same PLI Design Fails Upstream

Polysilicon production needs roughly ₹850 crore per GW - several times a module assembly line's capital requirement - plus years of continuous, cheap electricity for the energy-intensive Siemens process before a single tonne ships.

An output-linked incentive, which pays out only once production begins, does almost nothing to de-risk that multi-year construction and commissioning window. It works for assembly, where the gap between investment and output is short; it fails for polysilicon, where that gap is the entire problem investors are avoiding.

What a Bespoke Subsidy Would Actually Need to Fix For a

new polysilicon subsidy to succeed where PLI's extension has not, it would need to address the capital-intensity and power-cost problem directly - likely through upfront capital support or guaranteed power tariffs during construction, not just a per-unit payout after commissioning.

Without that redesign, India risks repeating the exact gap it has now: capacity announced, capacity built and still no buyers, because the underlying cost competitiveness against a fully-integrated Chinese supply chain was never actually closed.

For the exam, the transferable insight is that a subsidy instrument's design must match the specific capital-and-time profile of the segment it targets - an incentive that successfully builds downstream assembly capacity can simultaneously fail to build upstream capacity and celebrating the first without examining the second produces exactly the offtake crisis India now faces.
