Indian Solar Wafer Policy 2028: ALMM Rules, Deadline, Impact

The Indian solar wafer policy 2028 pushes domestic sourcing rules one step further up the solar supply chain.

In March 2026, the Ministry of New and Renewable Energy (MNRE) amended its Approved List of Models and Manufacturers (ALMM) Order to add List-III for ingots and wafers.

The list takes effect on 1 June 2028. Modules and cells are already covered, but wafers remain heavily import-dependent.

The shift is part of India's wider push for local value addition. It matters to manufacturers, project developers, EPC companies and procurement teams.

This article covers the provisions, timeline, commercial implications, domestic capacity, supply-chain resilience and compliance preparation.

Key Takeaways

• What the policy is: The first section explains ALMM List-III, the new tier covering ingots and wafers. It covers why MNRE is moving upstream and how ingots, wafers, cells and modules differ.
• When it applies: The second section sets out the 1 June 2028 effective date, the 15 GW condition for issuing the first list, and the seven-day cut-off. It also covers the transitional exemptions that depend on project route and dates.
• Who it affects: The third section looks at how manufacturers, developers, EPC companies and procurement teams are likely to be affected. It also covers supplier availability and the factors that could move pricing.
• Whether it can cut imports: The fourth section compares today’s roughly 2 GW of ingot-wafer capacity with the announced pipeline. It also covers the cost barriers and the polysilicon link that stays exposed.
• What to do now: The fifth section gives a ten-step compliance checklist for project mapping, key dates, supplier verification and contracts. It ends with answers to common questions on rooftop, open-access and pipeline projects.
