Field composites
Vikrant 44 years · Plant head · listed Indian module manufacturer
Runs a 2 GW module assembly plant that is ALMM-listed and PLI-eligible. The public announcement: Make-in-India solar, integrated manufacturing, national energy security. The composite-modelled friction is at the cell level. Cell manufacturing in India — poly-silicon to wafer to cell — remains capital-intensive and technologically concentrated. At year 2 of the PLI scheme, Vikrant's plant assembles modules from imported cells. The cells carry a Chinese origin footprint of ~70% across the sector. The ALMM listing covers the module. The PLI eligibility requires integration depth — but the depth milestone is phased, and the phase-2 commitment is three years out.
The publicly-disclosed PLI outlay drives the headline. The cell-import ratio sits inside the plant's procurement line, invisible from the ALMM list. BCD-40% on cells raises the input cost; it does not create the domestic cell supply to replace the import. The policy lever and the supply-chain reality operate on different timelines.

Sources modules for a 500 MW utility-scale project under SECI procurement. ALMM compliance is mandatory. The composite-modelled friction is the gap between the ALMM-listed module supply pipeline and the cost-quality-warranty envelope required for a 25-year project IRR. Three structural items surface:
- ALMM-listed domestic module supply at the required volume and delivery window: available — but at a price premium of 8–14% over non-listed alternatives, reflecting BCD pass-through and domestic capacity utilisation constraints.
- Module warranty and degradation curves for Indian-manufactured modules at project-finance grade: sparsely disclosed. Indian module manufacturers are 3–5 years younger in deployment vintage than Chinese counterparts. Long-term degradation data is actuarial projection, not field observation.
- Tariff bid competitiveness: ALMM compliance + BCD input cost absorption compresses the bid margin. The lowest SECI L1 bid in 2026 reflects a narrower developer margin than 2022, with module cost as the primary variable.
Ramesh 51 years · Senior MNRE policy advisor · ALMM scope + duty calibration
Works on the ALMM scope expansion and customs duty calibration question. Three structural tensions from the modelled scenario surface what the announcement layer does not resolve:
- ALMM enlistment audits the module. Cell + wafer + poly-silicon origin is not in scope. Expanding ALMM to the cell layer requires domestic cell supply at scale — which requires wafer capacity — which requires poly-silicon capacity. The integration chain is 4–5 years away from domestic sufficiency at the volumes the 500 GW target implies.
- BCD on cells at 40% raises the domestic module producer's cell input cost. If cell production does not materialise domestically, the BCD functions as a cost-pass-through to utility-scale developers and ultimately to power tariffs, not as an import-substitution accelerator.
- Local content measurement under Make-in-India procurement preference stops at the assembly stage for modules. The "local content" badge applies to a product whose upstream is predominantly imported. The measurement architecture and the supply-chain architecture are misaligned by design.
