ALMM List-II for Solar PV Cells: A Guide for Module Manufacturers & Buyers
ALMM List-II brings solar PV cells into India’s Approved List of Models and Manufacturers framework. For module manufacturers, procurement teams and other industry stakeholders, understanding the list means looking beyond a manufacturer’s name to the manufacturing facility, cell model, technology, enlisted capacity, validity and the latest MNRE requirements applicable to the project.
What is ALMM List-II?
ALMM List-II is the part of India’s Approved List of Models and Manufacturers framework that covers solar PV cells. The framework is administered by the Ministry of New and Renewable Energy (MNRE). List-I covers solar PV modules, while List-II identifies models and manufacturers of solar PV cells.
MNRE issued the first ALMM List-II for solar PV cells on 31 July 2025. Since then, the Ministry has published revisions and related orders and clarifications, making the latest official MNRE documents the appropriate reference for current procurement and compliance decisions.
Why ALMM List-II matters to module manufacturers
A solar module manufacturer does not buy a generic category called “an ALMM cell.” It buys a particular cell configuration from a particular manufacturing source for use in a particular module design.
That distinction is important when reading List-II. The official list can identify not only the manufacturer but also the manufacturing facility, enlisted capacity, solar cell type, model, efficiency and wattage information, and validity associated with the entry.
For procurement teams, this means an ALMM check should be specific. The relevant question is not simply, “Is this company on ALMM?” It is whether the current official list supports the manufacturer, facility and cell model being considered for the intended requirement.
Is the relevant cell represented in the current List-II?
Check the latest MNRE revision and identify the manufacturer, manufacturing facility, model, technology and validity shown for the relevant entry.
Does that cell meet the module manufacturer’s requirements?
Separately evaluate electrical bins, dimensions, thickness, metallization, interconnection, testing, sorting, production consistency and module-process compatibility.
ALMM List-I vs List-II: what is the difference?
List-I and List-II sit at different points in the photovoltaic manufacturing chain. Treating them as interchangeable can create confusion during sourcing and project evaluation.
| Point | ALMM List-I | ALMM List-II |
|---|---|---|
| Product covered | Solar PV modules | Solar PV cells |
| Manufacturing stage | Finished PV module | PV cell used in module manufacturing |
| What is identified | Models and manufacturers of solar PV modules | Models and manufacturers of solar PV cells |
| Typical B2B relevance | Module and project procurement | Cell sourcing and module manufacturing |
When did ALMM List-II for solar cells begin?
The cell list is relatively new compared with the module list, and the regulatory position has continued to develop through revisions, amendments and clarifications.
MNRE issued the Approved Models and Manufacturers of Solar Photovoltaic Modules (Requirements for Compulsory Registration) Order, establishing the ALMM framework.
The first ALMM list for solar PV modules was issued.
MNRE issued the first List-II specifically covering solar PV cells.
MNRE continued publishing revisions to List-II together with orders, amendments, FAQs and clarifications concerning its implementation and applicability.
The MNRE material published during 2026 includes additional clarifications and amendments concerning List-II. Applicability can depend on the relevant project category, procurement route, timeline and the latest government order. Project stakeholders should therefore check the current MNRE documents applicable to their specific case.
What should a buyer look for in ALMM List-II?
A useful way to read List-II is from left to right as a product and manufacturing identity check rather than treating it as a simple directory of company names.
Identify the legal manufacturer named in the official list.
Check the location associated with the relevant entry.
Review the manufacturing capacity shown for the manufacturing unit.
Check the technology and configuration identified for the cell.
Match the model under consideration with the model appearing in the list.
Review the average and/or published range associated with the entry.
Check the dates shown in the current revision rather than relying on an older copy.
The ALMM List-II document notes that solar-cell efficiency and wattage ranges are as claimed by the manufacturer. Where PID status is shown, the document similarly identifies PID as a manufacturer claim. A procurement team should therefore use the list together with the current product datasheet, agreed specifications and its own technical qualification process.
Are N-Type TOPCon solar cells represented in ALMM List-II?
Yes. Published ALMM List-II revisions include N-Type TOPCon solar cell models manufactured in India.
The official list shows that cell technology is not treated as a generic label. Individual entries can identify details such as N-Type TOPCon architecture, cell dimensions, busbar configuration, model information and associated efficiency or wattage ranges.
This matters to module manufacturers because two cells described broadly as “TOPCon” may still differ in format, electrical characteristics, metallization and other parameters relevant to module production. Regulatory status and technical suitability therefore need to be checked separately.
Review the actual TOPCon cell specifications
Learn how efficiency, Pmpp, Vmpp, Impp, Voc, Isc, fill factor, dimensions, thickness, metallization and testing information should be interpreted during B2B cell evaluation.
TOPCon Solar Cell Specifications →Does ALMM List-II replace technical supplier qualification?
No. An ALMM check and a technical supplier qualification serve different purposes.
List-II provides an official framework for identifying enlisted solar PV cell manufacturers and models. It does not remove the need for a module manufacturer to determine whether a particular cell is suitable for its product and manufacturing process.
Buyers moving from regulatory verification to supplier research can also review our guide to TOPCon solar cell manufacturers in India for a broader view of identified cell-manufacturing activity, manufacturing locations, technology platforms and the technical factors relevant to building a B2B supplier shortlist.
Before moving from regulatory verification to a purchase decision, a procurement and engineering team may need to review:
- the exact cell model and production source;
- cell format, dimensions and thickness;
- efficiency and electrical binning;
- Pmpp, Vmpp, Impp, Voc, Isc and fill factor;
- front and rear metallization configuration;
- testing, sorting and production consistency;
- traceability and quality-control documentation;
- handling, interconnection and module-process compatibility; and
- commercial supply requirements and agreed product tolerances.
In other words, finding the relevant entry in List-II can answer one regulatory question. It does not answer every engineering, quality or supply-chain question involved in purchasing solar cells.
How should module manufacturers evaluate an ALMM List-II cell?
Start with the latest MNRE List-II
Do not rely on an old downloaded copy or a supplier’s marketing statement. Check the latest official revision.
Match the manufacturer, facility and model
Confirm that the proposed source and exact cell configuration correspond to the relevant official entry.
Review validity and applicable MNRE requirements
Check the current list together with the orders and clarifications relevant to the project or procurement route.
Move to the cell datasheet
Compare the actual electrical, dimensional and metallization specifications required by the module design.
Qualify the manufacturing source
Evaluate process control, testing, sorting, traceability, documentation, production consistency and supply capability.
