MNRE Clarifies ALMM List II Solar Cell Rules: What Indian Developers Must Know

India's Ministry of New and Renewable Energy (MNRE) has issued a formal clarification on the applicability of the Approved List of Models and Manufacturers (ALMM) List II — which governs solar cells — across multiple categories of solar power projects. The move resolves months of ambiguity that had left developers, engineering procurement and construction (EPC) contractors, and equipment manufacturers uncertain about which projects must source solar cells from ALMM-approved domestic suppliers. ALMM List I, covering solar modules, has been mandatory for government-funded and government-procured projects since April 2022. List II, which extends that domestic-content framework to the solar cell level, is now being enforced with clearer sectoral boundaries. With India targeting 500 GW of installed renewable energy capacity by 2030 — of which roughly 300 GW is expected to come from solar — and SECI alone managing a pipeline of over 50 GW in active tenders, the compliance landscape for equipment sourcing carries enormous financial and operational stakes for every major developer in the country.

Which Solar Projects Must Comply With ALMM List II?

The MNRE clarification specifies that ALMM List II compliance for solar cells is mandatory for projects that fall under government-procured or government-assisted schemes — a category that encompasses the bulk of utility-scale solar development in India. This includes projects tendered by the Solar Energy Corporation of India (SECI), NTPC Renewable Energy Limited, and state nodal agencies procuring power on behalf of state distribution companies (DISCOMs). Projects developed under the PM Surya Ghar Muft Bijli Yojana — the flagship rooftop solar scheme targeting 10 million households — are also covered, reinforcing the government's intent to build a fully domestic solar manufacturing supply chain from cell to module. Independent power producers (IPPs) bidding into competitively tendered capacity auctions, including players such as Adani Green Energy, ReNew Power, Greenko, Torrent Power, and JSW Energy, must now ensure their module supply chains trace back to ALMM List II-approved cell manufacturers if those projects receive government offtake.

Critically, the clarification also delineates exemptions — or at least deferred timelines — for certain categories of projects, including captive and open-access solar installations that operate outside the government-procurement framework. This distinction matters because India's commercial and industrial (C&I) solar segment has been growing rapidly, with corporates across sectors signing power purchase agreements directly with developers. Those projects, for now, face a different — and less stringent — compliance regime, giving the private sector some breathing room while domestic cell manufacturing capacity scales up to meet demand.

Why ALMM List II Compliance Is a Manufacturing Milestone for India

The ALMM framework is one of the Indian government's most consequential industrial policy levers in the clean energy sector. By mandating that approved projects use only modules and, now, cells from manufacturers on the ALMM list, MNRE is effectively creating a guaranteed domestic demand signal for Indian solar cell producers — a segment that has historically lagged behind China's overwhelming global dominance. India currently has limited but rapidly expanding solar cell manufacturing capacity. The Production Linked Incentive (PLI) scheme for solar PV manufacturing, with an outlay of approximately ₹24,000 crore across two tranches, has already attracted commitments from companies including Adani Solar, Reliance New Energy, Waaree Energies, and First Solar's Indian operations. Clearer ALMM List II rules directly support the offtake case for these investments, assuring manufacturers that the projects they supply into will be held to domestic-sourcing standards, reducing the risk that cheaper imported Chinese cells undercut their margins.

For developers, the clarification introduces a new layer of supply chain due diligence. Procurement teams at large IPPs must now audit their module vendors to confirm that the cells embedded in procured modules originate from ALMM List II-approved manufacturers. Given that most thin-margin utility-scale solar bids are structured around specific equipment assumptions, any last-minute supplier substitution to achieve ALMM compliance could affect project economics. Industry bodies including the Indian Solar Manufacturers Association (ISMA) have long advocated for precisely this kind of downstream compliance rigour, arguing that module-level ALMM enforcement without cell-level oversight left a significant gap through which foreign-manufactured cells re-entered the supply chain inside Indian-assembled modules.

What This Means for India's Energy Transition

India's 500 GW renewable energy target by 2030 is not simply an electricity-sector goal — it is the foundation of the country's industrial and climate strategy. Achieving it requires not just gigawatts in the ground but a resilient, largely domestic supply chain that insulates Indian energy infrastructure from geopolitical supply shocks of the kind the world witnessed during the 2021–22 global solar module price surge. MNRE's ALMM List II clarification is a structural step toward that supply-chain sovereignty. By extending compliance requirements to the solar cell layer, the government is signalling that India's energy transition will be built on Indian manufacturing — from polysilicon and ingots, through wafers and cells, to finished modules. Rajasthan, Gujarat, Tamil Nadu, Andhra Pradesh, and Karnataka — the five states hosting the largest utility-scale solar parks — will all be affected, as the projects anchored in these states predominantly operate under government-offtake structures that now fall squarely within ALMM List II's mandate.

Developers, EPCs, and lenders financing Indian solar projects should watch two near-term developments closely: first, whether MNRE expands the ALMM List II approved-manufacturer roster fast enough to prevent supply bottlenecks during peak project commissioning cycles in 2025 and 2026; and second, how compliance enforcement mechanisms are operationalised at the project inspection and commissioning stage. The clarity MNRE has now provided is necessary — but execution will determine whether this policy drives genuine manufacturing depth or simply adds a compliance checkbox.
