The Ministry of New and Renewable Energy (MNRE) has issued Revision-L (50) of ALMM List-I for solar PV modules through its Office Memorandum dated 3 August 2026.
The latest revision expands and updates the list of eligible manufacturers and module models. However, one point is important to clarify: Revision-L does not introduce a new module-efficiency threshold. Instead, it reiterates the existing category-wise efficiency criteria while updating the manufacturers, models, capacities and validity details covered under ALMM List-I.
For crystalline-silicon modules, the efficiency thresholds currently referenced in the OM are:
- 20% – Utility/grid-scale projects
- 19.5% – Rooftop and solar-pumping applications
- 18% – Specified DRE/off-grid applications
- 19% – Other applications
Separate efficiency requirements continue to apply to CdTe thin-film modules.
What Has Changed in Revision-L?
Revision-L contains 13 manufacturing-unit entries, including seven new additions:
- Poola Energy
- HR Solar Solution
- SLR Solar
- Veda Solar
- Fujiyama Power Systems
- Adani New Industries
- Senses14 Power Solution
The revision also includes model and/or capacity updates for:
- Sova Solar
- Silver Consumer Electricals
- Credence Solar Panels
- RPSG Solvanta
- Goldi Sun
- SAEL Solar P6
Based on the capacities reported in Revision-L, the seven newly enlisted manufacturing units represent approximately 8.064 GW/year of ALMM-enlisted capacity, while all 13 entries together account for approximately 21.385 GW/year of listed capacity.
However, these numbers should not be interpreted as additional manufacturing capacity created by Revision-L. MNRE has clarified that when the capacity of an existing manufacturing unit is revised, the latest enlisted capacity replaces the previous figure. The two figures should therefore not be added together.
What Does This Mean for Solar Developers and EPC Companies?
For developers and EPC contractors, the bigger takeaway is not simply the number of manufacturers added to the list. It is the need for more precise procurement-level compliance.
Revision-L includes additions, amendments, model withdrawals and removals associated with BIS-registration status. MNRE also reiterates that ALMM enlistment remains conditional on the corresponding BIS registration being valid.
That means procurement teams should avoid relying on a broad statement such as:
“This manufacturer is ALMM approved.”
Instead, compliance should be verified at the level of the:
Manufacturer → Manufacturing Unit → BIS Registration → Module Model → Project Application Category
This distinction becomes particularly important when projects involve vendor substitutions, multiple module models or procurement from different manufacturing facilities.
N-Type TOPCon Continues to Gain Ground
Another notable feature of the latest revision is the strong representation of N-Type TOPCon modules.
Several newly listed models offer module efficiencies above 23%, reflecting the increasing availability of higher-efficiency products within the ALMM-approved supplier ecosystem.
However, this should not be interpreted as an MNRE mandate requiring a particular module technology. Revision-L does not make TOPCon compulsory. It simply reflects the technology mix and higher-efficiency products currently entering the approved supplier base.
The Procurement Process Needs to Change
For EPC companies, the practical implication is significant.
ALMM compliance should not be treated as a one-time statutory check performed at the beginning of a project. It needs to become part of the entire procurement and project-documentation process.
This includes:
- Vendor qualification
- Technical evaluation
- Purchase orders and contracts
- Module model verification
- BIS registration checks
- Manufacturing-unit verification
- Model substitution approvals
- Project documentation
- Final compliance records
This becomes especially important when a supplier proposes a model substitution after the original procurement decision.
A manufacturer being present on the ALMM list does not automatically mean every module supplied by that manufacturer is eligible for every project.
The Right Question to Ask
The procurement question is therefore no longer simply:
“Is the manufacturer ALMM listed?”
The better question is:
“Is this exact module model, manufactured at this specific manufacturing unit, under a valid BIS registration, eligible for this specific project application?”
That is the compliance discipline that Revision-L reinforces.
For solar developers and EPC companies, adopting this approach can help reduce procurement risks, avoid compliance gaps and create stronger documentation for project-level verification.
