ALMM List

ALMM and inverter compliance: MNRE’s current ALMM page publishes solar PV module and cell lists, not an inverter list. Verify the inverter’s exact model documents and applicable scheme or DISCOM requirements separately.

What is ALMM

ALMM listing requires BIS certification as a prerequisite, plus origin documentation, factory inspection by the National Institute of Solar Energy (NISE), and ongoing surveillance. Listings are routinely revoked when conditions change.

ALMM explained simply

If you are building a solar project that gets subsidy from the central government or wins a SECI tender, you must use modules from a published list of approved makers and approved models, built with cells from the companion cell list. The list is maintained by MNRE and updated every few months. Buy off-list and the subsidy will not come. Inverters are not on any ALMM list, so verify those against BIS registration and the standards named on the model documents.

Why ALMM matters

Subsidy gating. PM Surya Ghar, PM-KUSUM and CPSU schemes disburse subsidy only against ALMM equipment.

Quality floor. ALMM verifies BIS compliance, factory inspection and ongoing surveillance.

Indian manufacturing support. The mechanism effectively favours domestic manufacturers, aligning with Make in India and PLI policy.

Tender eligibility. SECI and most state utility tenders require ALMM-listed equipment.

Investor confidence. ALMM listing is a signal of regulatory acceptance and ongoing compliance.

How ALMM works

1. Manufacturer obtains BIS certification for the model.
2. Submits application to MNRE with origin documents and BIS test reports.
3. NISE conducts factory inspection at the manufacturing facility.
4. MNRE reviews and issues ALMM listing order.
5. Listing is published on MNRE website.
6. DISCOMs and tender authorities reference the published list.
7. Periodic surveillance may revoke listing for non-compliance.

For EPCs assembling subsidised rooftop or ground-mount portfolios, sourcing ALMM-listed equipment through a turnkey solar EPC partner that already tracks listing status simplifies compliance and avoids last-minute substitutions.

Technical deep dive

List structure

Each list entry includes manufacturer name, model, wattage or capacity range, date of approval, and validity.

Listing duration

Initial listing is typically valid for 2 years. Re-listing requires fresh inspection and certification.

Capacity tagging

Each model is listed with maximum cumulative dispatch capacity. Once a manufacturer exceeds the tagged capacity in a year, MNRE may pause new dispatches until inspection updates.

Real-world applications

Mandatory for PM Surya Ghar disbursement.

Required for SECI, CPSU, NTPC and most central tender bids.

Required for most state agency solar tenders (Gujarat Urja Vikas Nigam, Solar Energy Corporation of Karnataka, MEDA, AP Solar).

Required for state subsidy schemes in most cases.

Increasingly required by financiers as a quality signal.

Advantages

Quality assurance through standardised inspection.

Supports Indian manufacturing scale-up.

Simplifies DISCOM and tender authority procurement review.

Aligns with PLI scheme objectives.

Reduces import dependency in solar.

Limitations

Acts as a trade barrier under WTO interpretations, a concern that echoes debates around import duties on solar inverters in India.

Listing process can take 6 to 12 months, delaying new product launches.

ALMM premium has historically inflated module prices.

Surveillance and revocation can disrupt project pipelines.

Limited coverage of balance of system components.

Common problems

ALMM listing revoked mid-project, forcing equipment substitution.

New module wattage class not yet listed, blocking high-wattage bifacial projects.

Manufacturer at full ALMM-tagged capacity, unable to ship more.

Conflicting interpretation between MNRE and state DISCOMs on what counts as ALMM.

Best practices

Confirm ALMM status on the day of order and the day of delivery.

Maintain copies of ALMM listing PDFs in project files.

Build buffer time for ALMM revisions in project schedules.

Use only NISE-inspected manufacturer facilities for sensitive projects.

Track MNRE ALMM revision notifications.

Indian market context

Major ALMM-listed module manufacturers in 2026 include Adani Green Solar, Waaree Energies, Tata Power Solar, Vikram Solar, Goldi Solar, Premier Energies, RenewSys, Mundra Solar, Saatvik Green Energy and a growing list.

The PLI scheme accelerated Indian module manufacturing capacity, with several gigawatt-scale plants operationalising between 2023 and 2026. ALMM listings have grown commensurately.

Standards and certifications

These IS standards sit inside the wider BIS/IEC compliance framework for solar inverters that Indian buyers and EPCs must verify before commissioning.

Common mistakes

Buying modules from a manufacturer whose ALMM listing was just revoked.

Assuming all imported equipment is automatically ALMM-listed because the brand is famous.

Skipping date-of-supply verification, only confirming date-of-order ALMM status.

Mixing ALMM and non-ALMM equipment, voiding subsidy.

Forgetting that solar cells (List II) and modules (List I) are tracked separately.

Failing to keep ALMM documentation in project files for later audit.
