ALMM & DCR Panel Mandate 2026: How It Impacts Your Industrial Solar Project Cost

An industrial company is planning a 2 MW solar project.

The technical team has finalised the available area. Management has approved the broad investment. The expected generation and savings look attractive.

Then procurement receives two module quotations.

One is noticeably cheaper.

The other complies with the sourcing requirements applicable to the proposed project.

At first glance, this looks like a panel-price discussion.

In 2026, it can actually be a project eligibility, procurement and commissioning-timeline discussion.

India's solar manufacturing framework has changed significantly. MNRE's Approved List of Models and Manufacturers now covers not only solar PV modules under ALMM List-I, but also solar PV cells under ALMM List-II. The first List-II for cells was published on July 31, 2025, and the cell-related requirements became a major consideration for projects from June 1, 2026. Ministry of New and Renewable Energy

For factories planning industrial solar, this raises an important question:

Will the new requirements make our project more expensive?

Possibly.

But the answer is more nuanced than simply saying “Indian panels cost more.”

First, businesses need to understand what ALMM and DCR actually mean—and, importantly, that they are not the same rule.

First: ALMM and DCR Are Different

These terms are often used together in solar conversations, which creates unnecessary confusion.

ALMM

ALMM stands for:

Approved List of Models and Manufacturers

MNRE maintains approved lists of eligible manufacturers and models.

As of September 2026:

ALMM List-I → Solar PV modules

ALMM List-II → Solar PV cells

MNRE states that modules included in List-I are required for specified categories including government projects, government-assisted projects, projects under government schemes, open-access projects and net-metering projects. Ministry of New and Renewable Energy

DCR

DCR means:

Domestic Content Requirement

DCR requirements are intended to ensure domestic manufacturing/content is used in projects or schemes where those requirements specifically apply.

MNRE separately publishes DCR norms, including norms relating to solar PV cells. Ministry of New and Renewable Energy

So:

ALMM = approved-list eligibility

while

DCR = domestic-content requirement

They can interact, but they should not be treated as interchangeable terms.

That distinction matters when planning solar for industries.

What Changed in 2026?

Until recently, much of the industry's ALMM attention was focused on modules.

That changed with List-II.

MNRE published the first ALMM List-II for solar PV cells on July 31, 2025, and has continued updating it. By August 21, 2026, the ministry had already issued the 9th revision of List-II. Ministry of New and Renewable Energy

The major implementation date was:

June 1, 2026

MNRE confirmed in May 2026 that there would be no blanket extension of ALMM List-II beyond June 1, 2026, although provisions were introduced to protect certain investments already made. Ministry of New and Renewable Energy

Later, MNRE provided a limited commissioning window until December 31, 2026 for specified net-metering and open-access renewable-energy projects, rather than a universal extension for all projects. Ministry of New and Renewable Energy

This distinction is extremely important for industrial buyers.

Do not hear:

“There is an extension until December.”

and assume it automatically applies to your project.

The July notification describes a limited window, not a blanket postponement. Ministry of New and Renewable Energy

Why Does This Matter to an Industrial Solar Buyer?

Because module procurement is no longer only about:

• Wattage
• Efficiency
• Warranty
• Technology
• Price per watt

For projects falling within the relevant framework, procurement also needs to answer:

Is the selected module/model eligible under the applicable ALMM requirements?

What cell is used inside that module?

Does List-II apply to this project?

Does a transition or investment-protection provision apply?

When must the project be commissioned?

That last question can directly affect project cost.

A cheaper module that creates an eligibility or commissioning problem isn't actually cheaper.

Put the Cost Question Into Numbers

Consider an illustrative:

2 MW industrial solar project

Assume one compliant module procurement option costs:

₹0.75/W more

than another otherwise comparable procurement route.

Additional module procurement cost:

2,000,000 W × ₹0.75 = ₹15 lakh

For a 5 MW project:

5,000,000 × ₹0.75 = ₹37.5 lakh

For a 10 MW project:

10,000,000 × ₹0.75 = ₹75 lakh

Industrial Solar Capacity	Illustrative Premium	Additional Cost
1 MW	₹0.75/W	₹7.5 lakh
2 MW	₹0.75/W	₹15 lakh
5 MW	₹0.75/W	₹37.5 lakh
10 MW	₹0.75/W	₹75 lakh

These are illustrative numbers, not current market quotations.

The actual price difference changes with module technology, manufacturer, order volume, cell availability, commercial terms and market conditions.

But the example shows why policy changes that affect even a few paise per watt matter much more at industrial scale.

Don't Evaluate That ₹15 Lakh in Isolation

Now suppose the same 2 MW project is expected to generate an illustrative:

30 lakh units/year

At an avoided electricity value of:

₹8/unit

the annual energy value could be approximately:

₹2.4 crore

If the project operates for decades, a ₹15 lakh procurement difference needs to be evaluated against:

project eligibility, generation, commissioning certainty and lifetime economics.

That doesn't mean businesses should ignore module pricing.

It means procurement should not save ₹15 lakh upfront while creating a much larger regulatory or project-execution risk.

The Bigger Cost Risk May Be Delay, Not the Panel Premium

This is particularly important in 2026.

Imagine a 2 MW factory project expected to save:

₹15 lakh/month

once operational.

The project is delayed for three months because module procurement was planned around the wrong eligibility assumption.

Potential delayed savings:

₹15 lakh × 3 = ₹45 lakh

Suddenly, negotiating a ₹10–15 lakh module-price difference looks less important than ensuring the correct equipment is available at the right time.

This is one reason procurement planning matters more under changing compliance requirements.

The cheapest panel price is not necessarily the cheapest commissioned project.

ALMM List-I: What Industrial Buyers Should Know

MNRE's current ALMM framework states that only module models and manufacturers included in List-I are eligible for use in specified categories that include:

• government projects;
• government-assisted projects;
• projects under government schemes/programmes;
• open-access projects; and
• net-metering projects. Ministry of New and Renewable Energy

For an industry considering an open-access solar project, this makes ALMM a procurement-level question, not simply an EPC technical detail.

The List-I itself is updated periodically. MNRE published updated versions during 2026, including updates in July, August and September. Ministry of New and Renewable Energy

Therefore, checking:

“Is this manufacturer ALMM-listed?”

may still not be specific enough.

The project team should verify the applicable model and current list status at the relevant procurement/project stage.

List-II Moves the Discussion Inside the Module

A solar module is assembled from solar cells.

Historically, an industrial buyer might focus mainly on the module manufacturer.

List-II makes cell sourcing increasingly relevant for projects to which the requirement applies.

That means the procurement conversation becomes:

Who manufactured the module?

and

Which eligible cells are being used?

This has implications for module manufacturers too, because their ability to offer compliant products depends partly on eligible cell supply.

As domestic cell manufacturing capacity expands, availability and pricing should continue evolving.

But during a transition, supply constraints can affect:

module availability;

manufacturer selection;

delivery schedules;

and potentially

project pricing.

This is why a 2026 industrial solar installation should not rely on a module quotation prepared months earlier without reconfirming compliance and availability.

A Critical Point: Not Every Industrial Solar Project Has Identical Requirements

This is where blanket statements become dangerous.

A factory can install solar under different structures:

Behind-the-meter rooftop solar

Solar is installed at the industrial premises and primarily consumed on-site.

Net-metered solar

Generation and grid interaction operate under the applicable net-metering framework.

Captive/Open Access Solar

The generating project may be located elsewhere, with electricity supplied to the industrial consumer through the grid.

Government-supported or scheme-linked projects

Additional procurement requirements may apply.

The relevant ALMM and DCR treatment can differ depending on the project structure and applicable notification.

MNRE itself has issued multiple clarifications during 2026 covering rooftop projects, non-rooftop renewable projects, existing investments and particular categories. Ministry of New and Renewable Energy

Therefore, a factory owner should not ask:

“Does ALMM apply to industrial solar?”

The more useful question is:

“Which ALMM and domestic-content requirements apply to our specific project structure, procurement date and commissioning timeline?”

The December 31, 2026 Window Needs Careful Reading

This deserves special attention because it can easily be misunderstood.

After confirming there would be no blanket extension beyond June 1, MNRE subsequently announced a limited window until:

December 31, 2026

for commissioning certain net-metering and open-access renewable-energy projects, subject to the conditions in the notification. Ministry of New and Renewable Energy

This was designed to address particular transition circumstances and protect investments not to make List-II irrelevant until 2027.

So an industrial project scheduled for commissioning in:

October 2026

should not automatically assume it is exempt.

Its EPC/developer should establish whether the project meets the notification's specific eligibility conditions.

For management, this is an excellent due-diligence question:

“Show us the notification under which our project qualifies for the transition window.”

That is much stronger than accepting:

“Don't worry, the deadline extends ho gayi hai.”

Existing Investments Received Specific Attention

Policy transitions create a difficult problem.

What happens if a developer has already ordered modules or committed substantial capital before a new requirement takes effect?

MNRE addressed this in 2026 through provisions intended to protect certain investments already made under the existing ALMM framework.

The ministry also reopened the NISE DCR portal in July for submission of applications relating to protection of investments under its May 25, 2026 order. Ministry of New and Renewable Energy

This matters especially for large industrial and open-access projects where procurement commitments may be made months before commissioning.

It reinforces another lesson:

Document your procurement timeline.

Purchase orders, invoices, module details, delivery documentation and commissioning schedules can become important when transition provisions depend on what investment had already been committed by a particular date.

How Can the Mandate Affect Industrial Solar Project Cost?

There are at least five possible channels.

1. Module Procurement Cost

If the pool of eligible products is narrower than the unrestricted global market, pricing can differ.

The magnitude is market-dependent and should be checked using current quotations.

2. Availability

Even if an eligible module is competitively priced, it needs to be available in the required quantity.

For a 100 kW rooftop, this may be manageable.

For a:

5 MW

20 MW

or

100 MW

industrial/captive project, supply availability becomes a major procurement issue.

3. Project Schedule

Changing module suppliers late in the project can affect:

engineering;

string design;

mounting layout;

procurement;

and

commissioning.

Time has a financial value.

4. Financing

Lenders and investors want clarity that the project complies with applicable requirements.

Equipment eligibility uncertainty can therefore create financing and due-diligence friction.

5. Opportunity Cost of Delayed Generation

For an industry expecting ₹1 crore of annual electricity savings, every month of unnecessary commissioning delay represents roughly:

₹8.3 lakh of deferred savings

on a simplified basis.

That cost never appears on the module invoice.

But it is real.

Illustrative: Module Premium vs Delay Cost

Consider an industrial project where compliant procurement adds:

₹20 lakh

to the project.

Expected electricity savings:

₹1.2 crore/year

Monthly savings:

₹10 lakh

If choosing an incompatible procurement route causes a three-month delay:

₹30 lakh of savings are deferred.

So:

Upfront procurement difference = ₹20 lakh

versus

Three-month delayed savings = ₹30 lakh

The lesson isn't that expensive modules are always better.

It is:

Compare procurement decisions against total project economics, not price per watt alone.

DCR Can Also Affect the Commercial Conversation

Because DCR and ALMM are different, factory owners should ask separately:

Does this project require ALMM-listed equipment?

and

Does this project have a domestic-content requirement?

Do not assume one automatically proves the other.

For example, a project may be subject to approved-list requirements without the procurement discussion being identical to a DCR-linked government scheme.

This distinction should appear clearly in the EPC quotation.

Instead of writing only:

“DCR Module”

or

“ALMM Module”

the proposal should identify the actual module manufacturer/model, applicable list status and the regulatory basis relevant to the project.

Should Industries Rush to Buy Panels Before Prices Change?

Not necessarily.

Procurement driven by fear can create another set of problems.

A factory should not order thousands of modules before completing:

• site assessment;
• structural design;
• electrical engineering;
• project approvals;
• generation modelling;
• regulatory assessment.

The right approach is not:

Buy early at any cost.

It is:

Plan procurement early enough that compliance does not become a last-minute constraint.

For a multi-megawatt industrial solar installation, module strategy should be part of project planning from the beginning.

What About Solar Panels for Industrial Use Already in Warehouses?

Existing stock deserves careful verification.

A module physically available in India is not automatically eligible for every project.

Industrial buyers should establish:

• Manufacturer
• Model number
• Manufacturing details
• ALMM List-I status
• Cell sourcing/List-II applicability
• Relevant invoice/procurement dates
• Project commissioning requirements
• Any applicable transition provision

A warehouse full of modules has commercial value.

But whether those modules are appropriate for your specific project is a different question.

Does Domestic Manufacturing Automatically Mean Better Quality?

No.

This is another misconception worth avoiding.

Country of manufacture and product quality are different questions.

A good industrial solar procurement process should still evaluate:

• module efficiency;
• degradation warranty;
• product warranty;
• temperature coefficient;
• mechanical loading;
• technology;
• manufacturer track record;
• bankability;
• certifications; and
• after-sales support.

ALMM eligibility is not a substitute for technical due diligence.

Likewise, the lowest-priced eligible module is not automatically the best module for a 25-year industrial asset.

Compliance answers:

“Can this equipment be used under the applicable framework?”

Engineering still needs to answer:

“Is this the right equipment for this project?”

Why Technology Choice Still Matters

Suppose an industrial roof can accommodate only:

1,500 modules

Option A:

550 W × 1,500 = 825 kW

Option B:

600 W × 1,500 = 900 kW

Difference:

75 kW

At an illustrative annual generation of 1,500 units/kW:

75 × 1,500 = 1,12,500 additional units/year

At ₹8/unit:

₹9 lakh/year

So buying purely on module ₹/W can miss another important cost:

the value of limited roof area.

For space-constrained factories, module efficiency and wattage can materially influence lifetime generation.

The best compliant procurement is therefore not necessarily the lowest module price.

Industrial Solar Batteries Are a Separate Procurement Question

The 2026 ALMM cell discussion relates to photovoltaic cells used in solar modules.

It should not be confused with industrial solar batteries.

Battery energy storage has its own equipment, safety, performance and regulatory considerations.

If a factory is evaluating solar plus storage, procurement should therefore be divided into two technical workstreams:

PV module/cell compliance

and

Battery system design and compliance

A compliant solar module does not automatically tell you anything about whether the proposed battery system is well designed.

A Practical 2026 Procurement Checklist for Factory Owners

Before approving modules for a large industrial project, ask the EPC team to put these points in writing:

Check	Project Answer
Project structure	Rooftop / Net Metering / Captive / Open Access
Module manufacturer	___
Module model	___
ALMM List-I status	___
Cell manufacturer/source	___
ALMM List-II applicability	___
DCR applicable?	Yes / No + basis
Transition exemption applicable?	Yes / No + notification
Planned commissioning date	___
Module delivery date	___
Current quoted module price	₹___/W

Then ask:

“What happens to project cost and commissioning if this exact module becomes unavailable?”

A strong EPC partner should have an answer.

Don't Freeze a 2026 Project Using a 2025 Procurement Assumption

Solar policy and approved lists are moving quickly.

MNRE published the first solar-cell List-II in July 2025.

By August 2026, it had already reached its 9th revision. Ministry of New and Renewable Energy

List-I for modules has also continued to receive updates, including an update dated September 16, 2026. Ministry of New and Renewable Energy

This means an industrial solar feasibility report prepared six or nine months ago should not automatically be used to place today's purchase order.

Revalidate:

equipment availability;

list status;

applicable notification;

and

commissioning timeline

before procurement.

For current project teams, MNRE's official ALMM page should be treated as a primary reference rather than relying only on a vendor's old PDF or quotation.

Where Enersol Fits

For Enersol, the 2026 ALMM transition should not be treated as merely a panel-sourcing problem.

It is a project-planning issue.

Before finalising solar panels for industrial use, the team needs to understand:

• What type of project is being developed?
• Which requirements apply to it?
• When will it be commissioned?
• Which module and cell combinations are currently eligible?
• Are they available in the required quantity?
• How does the selected module affect system design and generation?
• What does changing suppliers do to project cost and timeline?

For a factory, the goal isn't simply to obtain the lowest module price.

It is to get the right industrial solar installation commissioned, compliant and generating electricity on schedule.

That is particularly important for multi-megawatt projects, where a small procurement decision can affect lakhs or crores of long-term electricity value.

Final Thoughts

ALMM List-II has made 2026 an important transition year for India's solar industry.

MNRE did not provide a blanket extension beyond June 1, 2026, although specific investment-protection provisions and a limited commissioning window through December 31, 2026 apply to qualifying projects. Ministry of New and Renewable Energy

For industrial buyers, the response should not be panic.

It should be better procurement planning.

Understand whether your project falls under the relevant ALMM requirements.

Separate ALMM from DCR instead of using the terms interchangeably.

Verify the actual module and cell combination.

Check the latest approved lists.

Confirm whether any transition provision genuinely applies.

And calculate the impact of module price together with the financial cost of a possible project delay.

Because for a factory planning solar for industries, the most expensive panel is not always the one with the highest ₹/W quotation.

Sometimes it is the panel that prevents a multi-megawatt project from being commissioned when the business expects it to start saving money.
