If you have received a solar quote in 2026, chances are “ALMM” appeared in the fine print, with nobody explaining what it gates. ALMM, the Approved List of Models and Manufacturers, is the Ministry of New and Renewable Energy’s (MNRE) eligibility list for solar modules and cells used in India’s government-linked solar projects. It decides whether your PM Suryaghar subsidy survives, whether your DISCOM (electricity distribution company) approves net metering, and whether your panels were ever legally allowed on a subsidised project.
Direct answer. ALMM is MNRE’s official list of approved solar module models and manufacturers, split into List-I (finished modules, mandatory since 2019) and List-II (solar cells, added 2025). Listing is required for PM Suryaghar, PM-KUSUM, and most SECI or DISCOM tenders. A 18 July 2026 MNRE order exempts net metering and open access projects from the List-II cell rule until 31 December 2026, but List-I module compliance never lapses.
This guide covers what ALMM regulates, how List-I differs from List-II, who must comply, and how to check whether your quoted module is really on the current list.
What Is the ALMM List?
ALMM stands for Approved List of Models and Manufacturers, a list MNRE first published in 2019 and updates every quarter at mnre.gov.in/almm. It names the specific solar module models, by manufacturer and model number, eligible for government-subsidised and government-linked solar projects in India.
The list exists to solve a trust problem. Before ALMM, subsidised solar schemes had no reliable way to stop cheap, uncertified modules from entering the market and failing within a few years. ALMM ties subsidy eligibility to a manufacturer clearing MNRE’s documentation review, factory checks, and Bureau of Indian Standards (BIS) test reports under IEC 61215 (design qualification) and IEC 61730 (safety qualification). A module that clears this bar earns a spot on the list; one that does not, cannot legally be used in a subsidised project.
ALMM splits into List-I and List-II, regulating two different physical parts of a module, and that difference decides most of the confusion buyers run into. Our glossary entry on ALMM has the deeper quarterly mechanics; this guide focuses on what a buyer or EPC (engineering, procurement, and construction) team needs to act on today.
ALMM List-I vs List-II: What’s the Difference?
List-I covers the finished solar panel; List-II covers only the solar cells sandwiched inside that panel. MNRE first issued List-I in March 2021, then added List-II for cells in July 2025 as India’s cell-manufacturing base scaled up under the Production Linked Incentive scheme. A module can sit on List-I while its cells are not yet on List-II, and whether that combination is legal right now depends on your project category.
| Dimension | ALMM List-I | ALMM List-II |
|---|---|---|
| Covers | Finished solar PV modules (panels) | Solar PV cells inside the modules |
| First issued | 2019, formalised March 2021 | 31 July 2025 |
| Mandatory for | PM Suryaghar, PM-KUSUM, SECI, most DISCOM tenders | Same categories, from 1 June 2026 baseline |
| Current exemption | None | Net metering / open access projects exempt until 31 December 2026 |
| Verification unit | Model number, not just brand | Cell source per manufacturer batch |
| Who checks it | Buyer, EPC, DISCOM inspector | EPC procurement team, MNRE audit |
The gap between the two lists is why India’s approved cell capacity, around 30 GW as of the seventh List-II revision (MNRE, April 2026), still trails its roughly 193 GW of module manufacturing capacity (industry estimate, 2026). Forcing every project onto List-II cells immediately would have stranded projects, the exact reason the 2026 exemption exists. Our companion piece on the ALMM List-II exemption window breaks down that timeline, with a five-check readiness test.
📘 Regulation note
List-I compliance has never had a general exemption. Every subsidised project has needed List-I-approved modules since the rule took effect. Only List-II has ever had a carve-out, for two narrow project categories.
Who Must Comply With ALMM?
ALMM compliance is not optional the moment government money touches your project. If you are claiming a PM Suryaghar rooftop subsidy, applying under PM-KUSUM, or bidding into a SECI or DISCOM tender, your modules must appear on the current List-I. Private commercial projects with no subsidy can legally use non-ALMM modules, but most banks and EPCs specify ALMM anyway as a bankability floor.
The bound categories, per MNRE’s notifications:
- PM Suryaghar residential rooftop, every module must be List-I approved, or the Direct Benefit Transfer (DBT) subsidy is denied.
- PM-KUSUM agricultural solar, pumps and decentralised plants under PM-KUSUM follow the same List-I gate.
- SECI and central tenders, utility-scale bids specify ALMM as a bid-eligibility condition.
- State DISCOM net metering, your DISCOM (UGVCL, DGVCL, MGVCL, PGVCL, BESCOM, and others) checks ALMM status at feasibility and inspection.
- Private commercial and industrial, no legal obligation without subsidy, but lenders increasingly ask for it.
A homeowner who accepts a quote for panels not on the current List-I is not just risking module quality; they are walking away from up to ₹78,000 in central subsidy the moment the DISCOM inspector flags it, per current PM Suryaghar scheme rules (MNRE, 2026).
How to Check If a Module Is on the ALMM List
Checking ALMM status takes under two minutes and is the single most useful thing a buyer can do before signing a quote. The mistake most people make is checking the brand name and stopping there; MNRE lists specific model numbers, not blanket brand approvals.
- Get the exact model number, not just “Waaree” or “Adani,” but the full alphanumeric model code.
- Visit mnre.gov.in/almm, MNRE hosts the current quarter’s lists as downloadable PDFs, by manufacturer.
- Search the manufacturer name first, narrow the PDF to your vendor’s section.
- Match the exact model code and wattage, manufacturers often have both listed and unlisted variants.
- Check the “as of” date, a model listed six months ago may have since been removed.
- Save a screenshot or PDF page, keep it with your quote paperwork for future disputes.
💡 Fast tip
If your EPC cannot immediately produce the model number and its ALMM listing page when asked, treat that as a red flag. A vendor that knows their supply chain has this answer ready.
If you are also comparing panel technologies, our guide on how to choose solar modules covers efficiency, temperature coefficient, and warranty alongside the ALMM check.
Across our 10,000-plus installations, ALMM disputes almost always trace back to skipping one of three checks, not genuinely counterfeit panels. We call it the Heaven Green 3-Point ALMM Verification Check: (1) model-level match, the exact code appears verbatim on the current list; (2) date-stamp check, the list referenced is the current quarter’s version; (3) category fit, the project type is matched against which list requirements apply, including any live exemption. Score all three “yes” and a module is procurement-ready.

The ALMM List-II Exemption: What Changed in 2026
This is the fact buyers most often get wrong in 2026, so it’s worth stating precisely, in MNRE’s own words. On 18 July 2026, MNRE issued Office Memorandum No. 283/53/2026-GRID SOLAR, stating that “while there will be no blanket extension in applicability of ALMM List-II for solar power projects,” a limited window applies to net metering projects and Open Access renewable energy projects: they “can now commission with exemption of ALMM List-II (for solar PV cells), till 31st December 2026.” Projects commissioned after that date must comply with List-II in full.
That deadline replaced an earlier cut-off of 31 May 2026. Two things are easy to miss: the exemption is scoped to net metering and open access projects only, and it touches List-II (cells) only. List-I stays mandatory throughout.
📘 Regulation note
MNRE's order states any reference to earlier superseded memoranda should be read as amended to 31 December 2026. An older article citing May 2026 or a different date is outdated.

Red Flags: ALMM Mistakes That Cost Buyers Their Subsidy
Most ALMM disputes are a skipped verification step, not deliberate fraud. These are the mistakes we see most often.
-
1
Verifying the brand, not the model number, only the exact model code matters.
-
2
Not re-checking before installation, the quarterly list can change between quote and install.
-
3
Assuming ALMM equals a performance guarantee, it certifies compliance, not 25-year output.
-
4
Mixing in one non-ALMM module, a single non-listed panel can jeopardise the entire subsidy claim.

ALMM vs BIS vs Tier-1: How the Three Quality Checks Differ
Buyers often confuse ALMM with BIS certification, and both with the informal “Tier-1” label. The Bureau of Indian Standards’ compulsory registration scheme underpins ALMM eligibility but is a separate certification.
| Aspect | ALMM | BIS | Tier-1 (BNEF) |
|---|---|---|---|
| Issuer | MNRE | Bureau of Indian Standards | BloombergNEF |
| What it certifies | Government subsidy eligibility, by exact model | Product safety and performance testing | Project-finance bankability track record |
| Mandatory for subsidy | Yes | Indirectly (BIS underpins ALMM eligibility) | No |
| Update cycle | Quarterly | Upon renewal | Quarterly |
| Buyer relevance | Highest (subsidy gatekeeper) | Medium (technical baseline) | High for large commercial financing |
Verdict. BIS is the technical floor every module needs. ALMM is the subsidy gate built on top of BIS. Tier-1 is a separate financial signal lenders use for large projects. For a subsidised residential job, ALMM is non-negotiable; for a large unsubsidised commercial plant, Tier-1 status often matters more.
For the domestic-manufacturing angle, see our explainer on DCR vs non-DCR solar panels and the DCR glossary entry, since DCR (Domestic Content Requirement) and ALMM are frequently mixed up. If you are trying to verify whether a quote is genuinely DCR-compliant, not just ALMM-listed, our guide on DCR vs non-DCR buyer impact walks through the documentation checks separately from the ALMM steps above.
Is an ALMM-Listed Module Always the Best Choice?
Not necessarily; ALMM certifies a minimum bar, not the ceiling.
- ✓ Protects subsidy eligibility end to end
- ✓ Improves loan approval odds
- ✓ Cleared IEC 61215/61730 testing at minimum
- ✓ Easier to defend at DISCOM inspection
- ✗ New models can lag months behind listing
- ✗ Sometimes a 5 to 10% price premium
- ✗ Removal mid-project can disrupt procurement
- ✗ Not a performance or degradation guarantee
The exception is a private, unsubsidised plant where the buyer has already vetted the manufacturer via Tier-1 status and PVEL testing data; a non-ALMM module can be defensible there, provided the buyer accepts it forfeits future subsidy eligibility.

Frequently Asked Questions
What does ALMM stand for?
ALMM stands for Approved List of Models and Manufacturers, MNRE’s eligibility list for solar modules and cells used in India’s subsidised and government-linked solar projects. First published in 2019, it is updated quarterly at mnre.gov.in/almm, tracked by exact model number, not brand.
What is the difference between ALMM List-I and List-II?
List-I covers finished solar PV modules and has been mandatory since 2019, formalised in March 2021. List-II covers the solar cells inside those modules, first published in July 2025. A 2026 order exempts net metering and open access projects from the List-II cell rule until 31 December 2026. List-I compliance has no general exemption.
Is ALMM compliance mandatory for all solar projects?
No. It is mandatory for projects receiving government subsidy or bidding into a central tender, including PM Suryaghar, PM-KUSUM, SECI tenders, and most DISCOM net metering programmes. Unsubsidised private projects can legally skip it, though lenders and EPCs often recommend ALMM-listed products anyway.
How do I check if a specific solar module is ALMM listed?
Visit mnre.gov.in/almm and download the current quarter’s List-I (and List-II, if relevant) PDF. Search for your manufacturer, then confirm the exact model number and wattage variant on your quote matches a listed entry, not just the brand name.
What happens if I install a non-ALMM module in a subsidised project?
The Direct Benefit Transfer subsidy is denied, which for a typical PM Suryaghar rooftop can mean losing up to ₹78,000 (MNRE, 2026). Even one non-listed module in an otherwise compliant array can jeopardise the entire subsidy claim.
What is the current ALMM List-II exemption deadline?
MNRE’s Office Memorandum No. 283/53/2026-GRID SOLAR, dated 18 July 2026, sets 31 December 2026 as the deadline for net metering and open access projects to commission with a List-II cell exemption. Projects commissioned later must fully comply. List-I stays mandatory throughout.
Does ALMM apply to solar inverters or only panels?
ALMM applies only to solar PV modules and cells. Inverters fall under a separate MNRE-empanelled vendor list, also subject to BIS and IEC compliance, but not part of the ALMM list itself.
Is an ALMM-listed module automatically a good quality panel?
Not automatically. ALMM certifies minimum documentation and BIS testing under IEC 61215 and IEC 61730, a floor, not a ceiling. Compare efficiency, temperature coefficient, and warranties beyond ALMM status alone.
