For five years, India's quality gatekeeping for solar stopped at the module. With ALMM List-II now coming into effect for solar cells, the rules reach one layer deeper — into the cells inside those modules. If you are commissioning a solar project under any government, net-metering or subsidised scheme, this directly affects which equipment qualifies. This is a practical, jargon-free explainer from our engineering team, written for project owners rather than policy specialists.
What is ALMM?
The Approved List of Models & Manufacturers (ALMM) is the Ministry of New and Renewable Energy's (MNRE) sourcing-and-quality gatekeeper for Indian solar. In simple terms, it is a published list of equipment that has passed inspection and is permitted in projects the government touches. The aim is twofold: ensure that subsidised and government-linked projects use genuinely reliable, traceable hardware, and build up India's domestic solar manufacturing base rather than depending on imports.
ALMM is enforced in two parts:
- List-I — solar modules. In force since 2021. For ALMM-applicable projects, only modules from listed manufacturers qualify.
- List-II — solar cells. The newer extension that applies the same control to the cells inside the module.
List-I vs List-II — the key difference
The distinction is straightforward once you see it side by side. List-I asks "is the finished panel approved?" List-II adds "and are the cells inside that panel approved too?"
| ALMM List-I | ALMM List-II | |
|---|---|---|
| What it lists | Solar modules | Solar cells |
| In effect | Since 2021 | Effective ~2026 (confirm latest notification) |
| Question it answers | Is the panel from an approved maker? | Are the cells inside also approved? |
| Who it affects | All ALMM-applicable projects | The same projects, one layer deeper |
| Practical impact | Choose listed modules | Choose listed modules with listed cells |
The headline takeaway: under List-II, it is no longer enough for the module brand to be ALMM-listed — for ALMM-applicable projects, the cells must come from a List-II manufacturer as well. A module assembled from non-listed imported cells will not qualify, even if the assembler is reputable.
Enforcement timelines and scope for List-II have moved more than once. Treat any specific date as indicative and confirm against the latest MNRE notification before you sign a procurement order.
Who does List-II apply to?
List-II rides on the same trigger as List-I: it applies to projects that already require ALMM-listed equipment. In practice that includes:
- Government and PSU tenders of essentially every size.
- Net-metered and subsidised rooftop, including residential systems claiming the PM Surya Ghar Muft Bijli Yojana subsidy.
- Open-access and scheme-linked C&I projects that draw on government incentives or grid-connected scheme frameworks.
- PM-KUSUM and similar agricultural solar schemes.
Pure private, non-subsidised CAPEX projects — for instance a factory self-funding a rooftop with no scheme benefit — carry more flexibility today. Even so, sourcing ALMM-compliant equipment has become the safe default for such owners, because it protects financing, resale value, and the option to claim future incentives. Note that ALMM (a quality/sourcing list) is a separate concept from DCR (Domestic Content Requirement, which governs subsidy eligibility) — a project can need one, both, or neither depending on the scheme.
What it means for your project
The shift from List-I to List-II changes three practical things for anyone procuring solar.
1. Cell origin now drives eligibility
Previously you checked the module brand against the list and moved on. Now the bill of materials matters. You — or, more realistically, your EPC — must verify that the cells in your chosen module trace back to a List-II manufacturer. This is a documentation and supply-chain discipline issue as much as a purchasing one.
2. Pricing and availability may move
Any time a compliance requirement tightens, the supply chain takes time to adjust. As more demand concentrates on listed cells, lead times and pricing for compliant modules can shift before they settle. The defensive move is to lock in compliant supply early for scheme-bound projects rather than assuming spot availability at commissioning.
3. Audit-proof documentation becomes mandatory
Net-metering approvals and subsidy disbursements increasingly require proof that both the module and its cells are listed. A project with the right hardware but missing paperwork can still stall at the DISCOM or scheme-audit stage. Clean datasheets, invoices, and traceability documents are no longer optional housekeeping — they are part of getting paid and energised on time.
How to stay compliant — a checklist
- Confirm whether your project is ALMM-applicable. Scheme-linked, subsidised, net-metered, or government projects almost certainly are.
- Specify modules that are List-I and built on List-II cells. Ask for written confirmation of cell origin, not just a module brochure.
- Cross-check DCR separately if you are claiming a subsidy — ALMM compliance does not automatically satisfy DCR.
- Collect and retain documentation — module datasheets, cell traceability, invoices — from day one.
- Re-verify against the latest MNRE notification before procurement, because dates and scope evolve.
Frequently asked questions
Does ALMM List-II apply to my private factory rooftop?
If your project is fully self-funded with no government scheme, subsidy, or net-metering dependency, ALMM may not be strictly mandatory today. But because it protects financing and resale value and keeps future incentives open, most owners now choose ALMM-compliant equipment anyway. If your rooftop touches any scheme, treat it as applicable.
Is ALMM the same as DCR?
No. ALMM is a quality-and-sourcing approved list. DCR (Domestic Content Requirement) is a content rule that mandates India-made cells and modules for certain subsidised schemes. A project can require both, one, or neither — see our DCR vs non-DCR guide.
What happens if I install non-listed cells on a scheme project?
The project can be rejected at net-metering or subsidy-audit stage, delaying energisation or disbursement — even if the hardware is otherwise good. That rework is far more expensive than getting the specification right upfront.
How do I know my modules use List-II cells?
You ask your EPC for written confirmation of cell origin and the supporting traceability documents. As a registered vendor we verify this as standard before procurement and hand the documentation over at project closeout.
Plan a compliant project with us
ALMM rules will keep evolving, and the cost of getting procurement wrong on a scheme-bound project — rejected applications, blocked subsidies, delayed energisation — far outweighs the effort of specifying correctly from the start. We track List-I and List-II, specify only compliant and bankable modules, and hand over the full documentation pack so your project clears net-metering and scheme audits the first time.
