A Comprehensive Guide to ALMM Certification
The Ministry of New and Renewable Energy established the Approved List of Models and Manufacturers (ALMM) as a mandated compliance framework for solar PV manufacturers that supply modules and cells to solar projects associated with the government.
The structure guarantees:
- The dependability and quality of the product
- Traceability of domestic manufacturing
- Standards for long-term performance
- Using authorized producers in initiatives funded by the government
ALMM: What is it?
The acronym for Approved List of Models and Manufacturers is ALMM.
It is regulated by:
MNRE released the “Approved Models and Manufacturers of Solar Photovoltaic Modules (Requirement for Compulsory Registration) Order, 2019.”
Currently, the ALMM consists of:
List | Covers |
ALMM List-I | Solar PV Modules |
ALMM List-II | Solar PV Cells |
Proposed List-III | Wafers & Ingots |
By 2026, ALMM regulations will extend farther into the solar manufacturing supply chain, encompassing ingots, wafers, and cells.
The Significance of ALMM Certification India
- Without ALMM clearance, manufacturers might not be able to provide modules or cells for:
- Solar projects run by the government
- Rooftop systems connected to subsidies
- Projects involving net-metering
- Projects with open access
- Tenders from the government
Important Authorities for ALMM Certification India
- New and Renewable Energy Ministry: Releases authorized lists and controls ALMM policy.
- Indian Standards Bureau: Manages testing compliance and BIS certification.
- Labs Accredited by NABL: Solar cells and modules must be tested at accredited laboratories.
The guidelines set for ALMM Certification India navigate companies to move on energy transition path.
Qualifications for ALMM Enrolment:
Solar producers need to:
- Run or own manufacturing facilities
- Maintain a current BIS certification
- Comply with MNRE production traceability requirements
- Provide technical specifications.
- Pass the factory’s verification and inspection
- Manufacturers from both India and beyond may apply, subject to the relevant regulations.
ALMM List-I vs List-II
Feature | List-I | List-II |
Covers | Solar Modules | Solar Cells |
Status | Operational | Implemented progressively |
Mandatory Use | Government-linked projects | Increasingly mandatory |
Focus | Module manufacturing | Cell manufacturing |
Recent revisions expanded domestic solar cell capacity under ALMM List-II significantly in 2026.
ALMM for Imported Solar Modules
Imported modules generally face stricter scrutiny under domestic manufacturing policies.
India increasingly promotes:
- Domestic cell manufacturing
- Domestic module manufacturing
- Upstream localization
The government is also expanding ALMM toward wafers and ingots.
