India’s solar push is one of the largest clean-energy programmes in the world, and the compliance framework behind it has become correspondingly strict. For anyone manufacturing, importing, or supplying solar photovoltaic (PV) modules, two acronyms dominate the conversation: BIS and ALMM. They are related but distinct, and understanding how they fit together is the difference between a module that can be used in subsidised projects and one that is effectively locked out of the market.

In simple terms, BIS certification proves a module meets India’s technical safety and quality standards, while ALMM — the Approved List of Models and Manufacturers, maintained by the Ministry of New and Renewable Energy (MNRE) — is the gateway list that determines which modules and manufacturers are eligible for government and government-assisted projects. BIS is the foundation; ALMM is the door it unlocks. This guide explains both, including the significant List-II change that took effect in June 2026.

1. The Two Layers: BIS and ALMM

It helps to think of solar compliance in India as two stacked layers:

• BIS certification — the technical conformity layer. It certifies that a PV module meets Indian Standards for design qualification and safety. Without BIS, a module cannot proceed to ALMM listing.
• ALMM — the market-access layer. Maintained by MNRE, it lists the specific models and manufacturers whose products are eligible for use in government projects, government-assisted projects, schemes such as rooftop and PM-KUSUM, open-access, and net-metering installations.

The relationship is sequential: a manufacturer first secures BIS certification for its module, then applies to have that model and manufacturing line enrolled on the ALMM. Without the BIS foundation, ALMM is simply not possible.

2. The BIS Standards for Solar Modules

Solar PV modules are certified against a set of Indian Standards harmonised with international IEC norms. The core standards include:

Standard	Scope
IS 14286	Design qualification and type approval of terrestrial PV modules (aligned with IEC 61215)
IS / IEC 61730	PV module safety qualification — construction and testing requirements
IS 16077 / IS 16221	Safety and performance requirements for terrestrial PV modules

These standards test a module’s ability to withstand real-world conditions — thermal cycling, humidity, mechanical load, insulation, and more. Certification is handled through the BIS conformity process applicable to PV modules, and it forms the technical evidence MNRE relies on for ALMM enrolment.

3. Understanding ALMM List-I and List-II

ALMM is structured in two lists that correspond to different points in the solar supply chain:

• List-I — covers finished solar PV modules (panels). Only models and manufacturers on List-I are eligible for use in government and government-assisted projects, open-access, and net-metering installations.
• List-II — covers the solar cells that go inside those modules. It targets the upstream component and is central to India’s drive to build a domestic cell-manufacturing base.

This two-list structure reflects a deliberate policy: it is not enough for the finished panel to be approved; increasingly, the cells inside it must also come from approved sources.

4. The June 2026 Change: Cell Sourcing Under List-II

Key development: ALMM List-II for domestically produced solar cells came into force on 1 June 2026. From that date, modules must use cells sourced from List-II-approved manufacturers in order to qualify for government subsidies and project approvals. In practice this means a module maker can no longer rely solely on its own List-I module listing — it must also ensure the cells it uses come from an approved List-II source.

For importers and integrators, this is a structural shift. A panel that was acceptable purely on the strength of List-I module approval may now fall short if its cells are not from a List-II source. Supply-chain documentation — proving where the cells originate — has become a compliance requirement in its own right. Manufacturers planning to supply the government-driven segment of the market must map their cell sourcing against List-II well ahead of bidding.

5. Why ALMM Matters Commercially

ALMM is not a safety mandate that applies to every single solar sale; rather, it is a powerful market-access gate. The vast majority of India’s solar deployment is connected in some way to government schemes, subsidies, open access, or net metering — and all of those channels require ALMM-listed modules. A module that is BIS-certified but not ALMM-listed can still exist in the market, but it is shut out of the largest and most bankable segment of demand.

In other words, for a serious solar business in India, ALMM listing is effectively commercial oxygen. That is why manufacturers treat the BIS-then-ALMM pathway as a strategic priority rather than a paperwork afterthought.

6. The Pathway: From BIS to ALMM

1. Secure BIS certification — Have the PV module tested and certified against the applicable Indian Standards (IS 14286, IS/IEC 61730, and related norms) through the BIS process.
2. Align cell sourcing — Ensure the cells used are sourced from ALMM List-II-approved manufacturers to retain subsidy and government-project eligibility.
3. Apply for ALMM listing — Submit the model and manufacturing-line details to MNRE for inclusion on ALMM List-I, supported by the BIS certification.
4. Facility verification — Be ready for inspection and documentation review of the manufacturing facility and supply chain.
5. Maintain and renew — Maintain certification, listing, and sourcing records, and renew as required to stay continuously eligible.

7. Common Pitfalls

• Ignoring List-II — Assuming List-I module approval alone is sufficient after the June 2026 List-II cell-sourcing requirement.
• Confusing the two — Treating BIS and ALMM as interchangeable — they are sequential layers, not substitutes.
• Weak supply-chain records — Failing to keep cell-origin and bill-of-materials documentation that proves compliant sourcing.
• Late starts — Underestimating the time required for testing, listing, and facility verification before a bidding deadline.

8. Domestic Content Requirements and the Push for Local Manufacturing

ALMM does not exist in isolation. It is one instrument in a broader policy that aims to build a self-reliant Indian solar manufacturing base — from modules down to cells and, eventually, wafers and ingots. A related concept that solar suppliers encounter is the Domestic Content Requirement (DCR), which mandates that modules used in certain government schemes be made in India using domestically manufactured components. The List-II cell-sourcing rule that took effect in June 2026 should be read against this backdrop: the direction of travel is steadily toward deeper localisation of the supply chain.

For an importer or an assembler, this matters strategically. A business model built purely on importing finished modules — or on assembling modules from imported cells — faces a narrowing path into the subsidised and government-linked segments of the market. Conversely, manufacturers who invest in domestic cell sourcing and List-II-compliant supply chains position themselves to capture the largest and most policy-protected share of demand. Understanding where your products sit on this spectrum is now a core part of solar business planning, not just a compliance detail.

9. Practical Steps for Importers and Developers

Whether you are a module supplier or a developer specifying panels for a project, a disciplined approach keeps you on the right side of both BIS and ALMM:

1. Verify BIS first — Confirm BIS certification of every module against the applicable Indian Standards before anything else.
2. Check List-I — Check that the specific model and manufacturer appear on the current ALMM List-I before committing to a government-linked project.
3. Validate cell sourcing — Trace the cell origin and confirm List-II-approved sourcing to protect subsidy and project eligibility.
4. Document the chain — Keep bill-of-materials and supply-chain documentation that can withstand verification.
5. Plan around deadlines — Build certification and listing timelines into project schedules well ahead of tender or commissioning deadlines.

10. Quality, Bankability, and Why Standards Matter

Behind the regulatory machinery, the purpose of BIS certification and ALMM is to ensure that the solar modules deployed across India actually perform and last. Solar projects are long-term assets, often financed on the expectation of 20 or 25 years of generation. A module that degrades prematurely or fails in the field does not just disappoint a single buyer — it undermines the financial model of the entire project and the confidence of the lenders and investors behind it.

This is where standards and bankability intersect. Financiers and large developers increasingly treat BIS certification and ALMM listing as baseline criteria for a module to be considered bankable. A panel that cannot demonstrate compliance is difficult to finance, difficult to insure, and difficult to sell into serious projects, regardless of its headline price. For manufacturers, then, compliance is not merely about clearing a regulatory gate; it is about being taken seriously by the capital that funds India’s solar build-out.

The reputational dimension matters as well. As India’s solar sector matures, buyers are scrutinising track records more closely. A manufacturer with consistent certification, a clean ALMM listing, and transparent supply-chain documentation builds the kind of credibility that wins repeat business. Compliance, in this sense, is a long-term brand asset rather than a one-time formality.

11. Looking Ahead: The Direction of Indian Solar Policy

The June 2026 enforcement of ALMM List-II for cells is unlikely to be the last tightening of the framework. India’s broader policy ambition is to localise more of the solar value chain over time — moving from modules to cells, and progressively toward wafers and ingots. Suppliers should plan on the assumption that domestic-content expectations will deepen rather than relax, and that documentation requirements proving the origin of components will become more, not less, demanding.

For businesses, the strategic takeaway is to stay ahead of the curve rather than react to each notification. That means tracking MNRE announcements closely, building relationships with compliant upstream suppliers early, and treating supply-chain traceability as a core capability. Companies that internalise this direction of travel — and invest in compliant sourcing before they are forced to — will be best positioned to win in the policy-driven segments that dominate Indian solar demand.

None of this should be navigated alone or at the last minute. The combination of BIS testing, ALMM List-I enrolment, and List-II cell-sourcing verification involves several authorities, defined timelines, and documentation that must hold up under scrutiny. The manufacturers and developers who succeed in India treat compliance as a project in its own right — resourced, scheduled, and owned by someone accountable — rather than a formality bolted on at the end. Starting early, keeping meticulous records, and seeking expert guidance where the requirements are ambiguous are the practical habits that turn a complex regulatory landscape into a manageable, repeatable process and keep your modules eligible for the projects that matter most. In a sector where a single missed listing or sourcing gap can disqualify an otherwise competitive bid, that discipline is not bureaucratic overhead — it is a direct contributor to commercial success, and it is what separates the suppliers who scale in India from those who remain stuck at the margins.

Frequently Asked Questions

Q. Do I need BIS certification if I only want to sell privately, outside government schemes?

BIS certification addresses the technical-standard requirement for PV modules and should be confirmed for your specific situation. ALMM, by contrast, is specifically the eligibility gate for government, government-assisted, open-access, and net-metering projects. Most commercially meaningful solar demand touches one of those channels.

Q. What changed on 1 June 2026?

ALMM List-II for solar cells came into force. From that date, modules must use cells from List-II-approved manufacturers to qualify for government subsidies and project approvals — extending the approval requirement from the finished module to the cell inside it.

Q. Is ALMM listing permanent?

No. Listings are maintained by MNRE and are subject to validity periods, renewal, and ongoing compliance, including facility and documentation verification.
