India is in the middle of one of the largest industrial build-outs of its modern history. We map the value chain, the opportunity, and the names doing the building.
Indian solar manufacturing has, in less than five years, gone from a marginal industry to a strategic priority backed by hard policy, hard capital, and hard demand. We think the build is one of the most consequential industrial stories in the country today.
India installed a record 45 GW of solar capacity in FY26 — more than the country had built cumulatively in the entire decade prior. The total non-fossil installed base now stands at roughly 267 GW, against the COP26 commitment of 500 GW by 2030. The arithmetic is simple: India has to add approximately 58 GW of non-fossil capacity every year for the next four years. Solar, by some margin, will carry the bulk of that. This is not a forecast; it is a contractual reality already baked into the policy architecture, the auction pipeline, and the offtake pre-commitments of state utilities.
What makes this moment different from prior solar booms is that, this time, the value of building it is being designed to stay inside the country.
The earlier decade of solar deployment was a generation-side trade — developers won reverse auctions on the lowest tariff per kWh and bought their modules wherever they were cheapest, which was almost always China. Tariffs collapsed from ₹17.91/kWh in 2010 to ₹2.00/kWh by 2017. India deployed solar capacity. China captured the manufacturing value.
Three forces have shifted that calculus, and shifted it permanently.
Demand hardened. The 500 GW commitment, the PM Surya Ghar rooftop scheme, the PM-KUSUM agriculture programme, and the SECI tendering pipeline together turned 30–40 GW of annual solar demand from a forecast into a multi-year contractual obligation.
Policy hardened in parallel. Between 2018 and 2025, India layered safeguard duty, then Basic Customs Duty (40% on modules, 25% on cells), then the Approved List of Models and Manufacturers (ALMM) — effectively a non-tariff barrier wrapped in an engineering certification — then PLI Tranches I and II for integrated manufacturing, with a third tranche on polysilicon and wafers in active design at the time of writing.
Capital followed both. Indian solar manufacturers — listed and unlisted — have collectively committed in excess of ₹1.5 lakh crore of disclosed capex toward integrated cell, module, ingot, wafer, and battery capacity through 2028.
The result is an industry that, only four or five years ago, did not meaningfully exist as an investable proposition in India, and today represents one of the most aggressive industrial scaling stories on the subcontinent. We are spending substantial research bandwidth on it because we think the economics are now firmly on the side of the people building inside the wall — and the wall is rising fast.
A 50 GW build-out year creates value at every layer of the chain. We are interested in the layer where the value is most asymmetric — and most protected.
There are at least four ways to be exposed to India's solar story. You can own the developers (Adani Green, ReNew, Azure). You can own the integrated utilities (NTPC, Tata Power, JSW Energy). You can own the EPC contractors. Or you can own the manufacturers — the firms that physically make the wafers, cells, modules, and increasingly the batteries that go into every plant. We have a clear preference for the fourth.
Indian solar manufacturing operates inside what is now one of the most protected industrial corridors in the country. The protection has three layers, each independently meaningful and together formidable:
The duty wall. Basic Customs Duty plus Agriculture Infrastructure and Development Cess together produce an effective import burden of roughly 27.5% on cells and 44% on modules. The Union Budget 2025 reshuffled the components but kept the headline level intact. As long as imported product carries that wedge, domestic manufacturers operate with a structural pricing umbrella.
The ALMM gate. The Approved List of Models and Manufacturers is, in effect, a non-tariff barrier wrapped in an engineering certification. To bid into any government-mandated tender — which is the bulk of India's pipeline — your modules must be on List-I and, from 1 June 2026, your cells must be on List-II. Foreign suppliers are, with rare exceptions, not on these lists. This is the single most important date in the sector calendar this year.
The DCR premium. Modules carrying the Domestic Content Requirement certification — meaning the cells inside are Indian-made — currently sell at ₹23–24 per Wp against ~₹18.5 per Wp for non-DCR equivalents. That ₹4.5–5.5/Wp premium translates into approximately 300–350 basis points of EBITDA margin for the manufacturer who owns both the cell and the module step. This is not a forecast. It is what listed Indian module companies are realising today, on the order books they are filling now.
The most striking single number in Indian solar manufacturing is the gap between module capacity and cell capacity. India has built roughly 210 GW of nameplate module capacity against domestic annual demand of around 50 GW. That is a fourfold oversupply at the module step. At the cell step, however, the picture inverts violently. India has roughly 27 GW of cell capacity — about 15% of module nameplate. A module-maker without an in-house cell line either depends on imports (now blocked from public tenders) or buys merchant cells from one of a handful of domestic producers.
From 1 June 2026, that merchant-cell market becomes the choke point of the entire Indian solar pipeline. Module makers without cells will be forced to either buy from domestic peers (at whatever price the cell-makers can charge) or build their own. Both responses take time. New cell lines take 8–12 months to commission and another 6–8 to stabilise yields. Anyone with a working, ALMM-listed cell line on 1 June 2026 owns a piece of pricing power that nobody had a year earlier.
This is what we mean by value migration. The locus of profitability in Indian solar is moving up the value chain, from EPC and assembly to cell and wafer integration. The further upstream a manufacturer is integrated, the better insulated it is — and the better positioned to capture margin during the 24-month window of cell scarcity that is now beginning.
The contrast with utilities is sharp. A solar IPP signing a 25-year PPA at ₹2.50/kWh in today's competitive auction has, essentially, locked in its tariff and most of its returns. The IPP's upside is leverage, scale, and execution — necessary, but not asymmetric. A manufacturer with ALMM-listed cell capacity in mid-2026 is selling into a structurally short market for at least two years, with margins already 300+ bps higher than the merchant alternative. We see the asymmetry on the manufacturing side.
India's solar manufacturing universe contains roughly fourteen names large enough to matter. Some are listed, some are subsidiaries of large conglomerates, some remain unlisted. We are studying all of them in parallel, because the relative attractiveness of any one position depends on what is happening at the others.
The visual below is our internal map. The vertical axis ranks each manufacturer by the depth of backward integration — how far upstream they have built into cells, wafers, and polysilicon. The horizontal axis ranks each by scale — operational module capacity at end of FY26. The bubble size approximates each company's stated FY28 capacity ambition. The map collapses a great deal of nuance into two dimensions, but it is a useful first lens for understanding where each operator sits in the field.
Below is the full list of the names we are actively studying, with a one-line read on each. We have ordered them by integration depth and scale, but no name on this list is being treated as a primary or peripheral case — the entire field is on the bench.
The same demand environment is producing three structurally different ways to win. Each is a distinct investment thread with a distinct set of leaders inside the universe above.
Thread one — vertical integration. When you can run from sand to module under one roof, the cost moat is not a function of unit prices but of how many cross-interfaces you have eliminated. Reliance Industries and Adani Solar are the leading exemplars. Long-duration thread; capital-intensive; payoff measured in years.
Thread two — scale and order pipeline. When demand is multi-year and contractually locked, the operator with the largest ALMM-listed module capacity and the most disciplined order conversion captures the most volume — and the most operating leverage. Waaree Energies, Avaada Electro, and Vikram Solar sit on this thread. Medium-duration; the export-heavy names carry a binary on US-India trade.
Thread three — cell specialisation. When the entire value chain is bottlenecked at the cell step, the operator with the cleanest, ALMM-listed, latest-generation cell line owns a piece of pricing power that nobody had a year earlier. Premier Energies is the cleanest exemplar; ReNew Power, JSW Renew Energy, and RenewSys India sit on adjacent versions of the same thread. Near-term; the cleanest near-term thesis in the sector.
Some names — Tata Power Solar, First Solar India, Goldi Solar, Rayzon Solar, and the smaller listed names — sit between or across these three threads, with elements of each. We do not think of them as outside the picture; we think of them as positions to be evaluated against the same demand backdrop, with their own particular lenses (component integration, thin-film differentiation, residential channel strength, capital structure flexibility) added in. We are reading them in parallel.
This note is the first in a sequence. Over the coming weeks, we will publish detailed work on each of the dimensions that matter — and on each of the names above.
We are actively tracking each of the names listed in Section Three. Our research is reading the entire field in parallel, and our intent is to publish thematic and company-specific notes as our work on each matures. The reason for the staged approach is that the sector is at a hinge moment — ALMM List-II implementation, the US ITC final ruling, potential PLI Tranche-III on polysilicon and wafers, and quarterly results across the universe — and we want to publish each piece against the actual data, not against forecasts of it.

The full sweep of how Indian solar policy went from generation-side incentives to manufacturing protectionism. Why each step was taken, what each accomplished, and what the next step (PLI Tranche-III on polysilicon and wafers) is likely to look like.
Detailed reports on each of the names we are actively tracking, released as our research on each matures. Each will be backed by a working financial model, peer comparison, scenario analysis, and our considered view on the investment angle. The order of publication will be set by the timing of catalysts and quarterly results, not by any predetermined ranking.
ALMM List-II final notification, US ITC ruling, Premier Q4 FY26 results, Reliance polysilicon commissioning, Union Budget 2027 PLI announcements. We will publish short notes against each — usually within 24–48 hours of the event.
The Indian solar manufacturing sector is, at the time of writing, at the most structurally interesting point in its short history. The duty wall is in place, ALMM List-II is days away from binding, the cell shortage is real and quantified, and a meaningful set of Indian companies are now large enough — and integrated enough — to capture the value. We think this is a sector worth understanding properly, at the scale of months of research, not days. This note opens that work. The rest follows.
