What Is ALMM?

What is ALMM?

ALMM is the central government's approved equipment list for solar projects that use any form of government funding or subsidy. MNRE maintains the list, updates it through gazette notifications, and enforces it across PM Surya Ghar, SECI auctions, state DISCOM tenders, and most MNRE-administered programmes. A project that uses non-ALMM modules or inverters is disqualified from subsidy and government procurement, even if the equipment is otherwise BIS-certified.

The list has two practical components. ALMM List I covers Indian-made modules. The MNRE has at different times maintained an ALMM List II for international manufacturers, with recent policy direction tightening the scope of foreign-listed equipment. An inverter ALMM list extends the same approach to grid-tie inverters.

ALMM does three things at once. First, it enforces a quality floor through BIS certification and factory audit. Second, it channels demand into Indian-manufactured equipment, supporting domestic manufacturing capacity. Third, it gives EPCs and customers a verifiable shortlist of approved suppliers.

Why ALMM matters

For solar EPCs handling PM Surya Ghar or any government-funded project, ALMM compliance is non-optional. The application fails at portal verification if non-ALMM equipment is used. The installer is responsible. A single non-compliant module in a subsidy-eligible project blocks the disbursement for the whole project.

For private commercial rooftop projects without subsidy, ALMM is technically not mandatory but is usually preferred. ALMM modules carry the credibility of MNRE approval, simplify resale, and align with manufacturer warranty practices.

For Indian module and inverter manufacturers, ALMM listing is effectively the licence to sell into subsidised and government markets, which is the majority of Indian rooftop demand. ALMM-listed manufacturers command price premiums of 5 to 15 percent over non-listed equivalents.

For policy, ALMM is the equipment-side enforcement of the broader Atmanirbhar Bharat manufacturing push. Combined with the PLI scheme for solar PV and the DCR, it forms a layered framework that builds domestic capacity over time.

How ALMM listing works

1. Manufacturer application. A solar manufacturer applies to MNRE with documentation: BIS certification, factory location proof, manufacturing capacity declarations, and product datasheets.
2. Technical review. MNRE checks BIS certificates, IEC test reports, and that the products meet specified IEC 61215, IEC 61730, and Indian standards.
3. Factory audit. An accredited audit may be conducted to verify manufacturing capacity and quality processes.
4. Gazette notification. Approved manufacturers and specific models are notified through the Gazette of India.
5. Quarterly updates. Subsequent updates add new models, revise capacity, and occasionally remove manufacturers who fail compliance.
6. Enforcement. EPCs verify ALMM listing at the time of equipment sourcing. DISCOMs check the model number against the current list at commissioning. Portal verification at PM Surya Ghar confirms eligibility.
7. Subsidy release. Only ALMM-verified projects pass the portal check that triggers central subsidy disbursement.

Real example: ALMM check in a PM Surya Ghar workflow

Setup. A solar EPC in Bhubaneswar quotes a 3 kWp residential installation under PM Surya Ghar. The customer wants the cheapest possible system to keep out-of-pocket low.

Module choice. The EPC initially considers a low-cost imported module not on ALMM. The cost saving versus an ALMM-listed Indian module is roughly ₹4,500 across nine modules.

Compliance check. The ALMM verification step on the National Portal flags the model number. Subsidy is held.

Correction. The EPC reorders ALMM-listed Indian modules of equivalent rating, swaps them in, and re-submits. The DISCOM re-inspects, confirms, and releases the commissioning certificate. Subsidy of ₹78,000 disburses.

Cost impact. The EPC absorbs ₹4,500 of additional module cost and lost time. The customer receives the subsidy as expected. The lesson is internalised: always cross-check ALMM before ordering for any subsidy-eligible project.

Benefits of ALMM

• Quality assurance. Filters non-BIS-certified equipment out of subsidy-eligible projects.
• Verifiable shortlist. EPCs and customers have a single authoritative list to source from.
• Manufacturer accountability. Listed manufacturers face oversight and the threat of de-listing.
• Domestic manufacturing support. Channels subsidy demand into Indian-made equipment.
• Warranty alignment. Listed manufacturers maintain India-based service networks.
• Subsidy gate. Single procurement check enables clean subsidy release.

Limitations of ALMM

Cost premium. ALMM-listed equipment is typically 5 to 15 percent more expensive than non-listed imports.

Limited choice. Newer or niche manufacturers (especially smaller domestic players) face a long approval cycle.

Foreign-manufacturer access uncertainty. Policy direction on foreign listings has shifted; planning long-term sourcing requires watching MNRE notifications.

Enforcement burden on EPCs. The installer is the last line of defence. Mistakes cost time and money.

Lag between technology and listing. A new module technology can wait several quarters before ALMM approval.

Industry friction. Some developers argue ALMM raises costs above what tariff structures comfortably support.

Common mistakes about ALMM

1. Buying based on an old ALMM list. Always check the current quarter's notification.
2. Confusing ALMM with DCR. They overlap but are not identical. DCR requires Indian-made cells in addition to Indian-made modules.
3. Assuming all imported modules are non-ALMM. Historically List II included some foreign manufacturers. Verify per current policy.
4. Skipping inverter ALMM check. Modules and inverters both need to be ALMM-listed for subsidy projects.
5. Mixing ALMM and non-ALMM modules in the same project. The subsidy application requires the full equipment list to comply.
6. Assuming higher Wp modules are automatically ALMM-listed. Listing is by manufacturer + model + rating. Confirm before ordering.
7. Ignoring ALMM for commercial projects expecting later subsidy. If subsidy is a possibility, source ALMM from day one.
8. Forgetting that warranty service depends on manufacturer presence. ALMM listing usually correlates with strong Indian service networks, but verify directly.

Key takeaways

• ALMM is the MNRE-maintained list of solar modules and inverters approved for subsidy-eligible and government projects.
• Non-ALMM equipment disqualifies subsidy under PM Surya Ghar and excludes from SECI tenders.
• The list is updated quarterly through gazette notifications.
• ALMM-listed equipment costs 5 to 15 percent more but unlocks subsidy and DCR alignment.
• Both modules and inverters have separate ALMM lists; both need compliance.
• For PM Surya Ghar, always cross-verify model numbers against the current notification before ordering.
