DCR vs Non-DCR Solar Panels: What the ALMM List-II Rule Means for You (2026)

Quick answer: DCR panels are solar panels made in India using solar cells that are also made in India. Non-DCR panels may be assembled in India but use imported cells. If you want the PM Surya Ghar subsidy, you must use DCR panels. Since 1 June 2026, India's ALMM List-II rule also requires cells from approved Indian manufacturers for most government-linked projects. Net-metering projects that do not take the central subsidy have a temporary exemption from the cell rule until 31 December 2026. DCR panels cost more per watt, but for a subsidised home system the subsidy more than covers the difference.

If you have asked a few installers for a rooftop solar quote recently, you have probably heard two words again and again: DCR and ALMM. One quote says "DCR panels, subsidy eligible". Another is ₹20,000 to ₹30,000 cheaper and says "non-DCR, TOPCon, high efficiency". Some installers say non-DCR panels are now "banned". Others say they are fine.

The rules did change in 2026, and the confusion is costing people money. Some families sign for cheaper panels and then find out at inspection that they cannot claim the ₹78,000 subsidy. Others overpay for DCR panels on a system that was never going to get a subsidy. This guide explains, in plain language, what DCR and non-DCR mean, what the ALMM List-II rule changed on 1 June 2026, which projects it applies to, how prices compare, and how to check that the panels on your roof are what your invoice says.

First, the basics: cells vs modules

A solar panel (also called a module) is made of many small solar cells joined together, covered with glass and fitted in an aluminium frame. The cell is the part that actually turns sunlight into electricity. India has a large module-assembly industry, but for years most of the cells inside those modules were imported, mainly from China.

That is why the place where the cell is made matters for government rules, not just the place where the panel is assembled. A panel can carry an Indian brand name and be assembled in Gujarat, and still be non-DCR because its cells came from abroad.

What is a DCR solar panel?

DCR stands for Domestic Content Requirement. A DCR panel is a module made in India using solar cells manufactured in India. Government schemes that give subsidies or other benefits use DCR rules to support Indian manufacturing.

A non-DCR panel uses imported cells. It may still be a high-quality panel from a reputed brand, and the technology (Mono PERC, TOPCon, bifacial) can be the same. The difference is where the cell was made, not how good the panel is.

ALMM stands for Approved List of Models and Manufacturers. It is maintained by the Ministry of New and Renewable Energy (MNRE) and lists solar products and factories that have been inspected and approved (MNRE ALMM page).

• ALMM List-I covers solar modules. Projects covered by ALMM must use module models from approved manufacturers on this list.
• ALMM List-II covers solar cells. It was introduced so that covered projects would also use cells from approved manufacturers, which in practice means Indian cell factories. The first List-II was published in July 2025 and it has been revised many times since as new factories are added.

MNRE has also announced that wafers, the thin slices from which cells are made, will get their own list (List-III), with a much later start date.

What changed on 1 June 2026?

From 1 June 2026, ALMM List-II for solar PV cells came into effect. Projects covered by ALMM now have to use modules from List-I and cells from List-II (Power Line, August 2026). In simple words, for covered projects, the cells inside the panel must come from an approved Indian cell manufacturer.

This created a short-term squeeze. India had far more module-assembly capacity than cell capacity, so DCR panels became harder to get and more expensive in early 2026, and some rooftop installations slowed down. To ease the transition, MNRE gave a few targeted relaxations instead of a blanket delay.

The net-metering exemption until 31 December 2026

On 18 July 2026, MNRE extended an exemption for net-metering and open-access projects: those commissioned on or before 31 December 2026 do not need List-II cells, although they still need List-I modules where applicable (PV Tech). MNRE described this as "a limited, project-specific relaxation". From 1 January 2027, these projects are expected to use List-II cells as well.

What the exemption does not cover

The exemption is about the ALMM cell rule for net-metering and open-access projects. It does not remove the DCR condition of subsidy schemes. Under PM Surya Ghar, the central subsidy is only given for systems that use DCR panels, that is, modules made in India from Indian cells. MNRE has also linked the PM Surya Ghar portal with a DCR verification system so that panel serial numbers can be checked (SolarQuarter).

Which rule applies to your project?

Use this table to find your situation. If you are not sure, ask your installer to confirm in writing which rule they are following.

Our step-by-step guide to the PM Surya Ghar application process shows where the panel details are checked.

Price: how much more do DCR panels cost?

In early 2026, when cell supply was tight, DCR TOPCon modules were trading at nearly double the price of non-DCR TOPCon modules per watt: market analysts reported about US$0.29 per watt for DCR against about US$0.155 for non-DCR at the end of January 2026 (SMM analysis). Industry surveys in India put DCR modules at roughly ₹23–26 per watt and non-DCR at around ₹15 per watt in the same period. The gap has been narrowing as more Indian cell factories come online, but it is still real.

What does that mean for a home system? The panels are only one part of the cost; the inverter, structure, cables, labour and paperwork are the same either way. On a 3 kW system (about 3,000 watts of panels), a gap of ₹8–10 per watt adds roughly ₹24,000 to ₹30,000 to the panel cost.

But the pattern holds: for a home that qualifies for PM Surya Ghar, DCR panels with the subsidy are almost always cheaper overall than non-DCR panels without it. Non-DCR panels can make sense for systems that would not get a subsidy anyway, such as larger shops, offices and factories, or homes that have already used their subsidy.

Also remember that GST on solar modules and solar power devices was cut from 12% to 5% from 22 September 2025 (pv magazine). If a quote still shows 12% on panels, ask why.

Is a DCR panel lower quality?

No. DCR is about where the cell is made, not about efficiency. Indian manufacturers now produce Mono PERC and TOPCon cells, and many DCR panels are in the 540–590 watt range. A non-DCR TOPCon panel may give slightly higher output per square foot in some cases, but on a typical home roof the difference is small compared with the effect of shade, tilt and dust.

What matters more for your 25-year investment:

• The manufacturer's product warranty (often 10–15 years) and performance warranty (often 25–30 years).
• Whether the manufacturer has a service presence in your state.
• The installer's workmanship: structure, earthing, cable routing and inverter sizing.
• Regular cleaning. Dust can cut output noticeably in dry months; consider a solar cleaning and maintenance service if you cannot clean the panels yourself.

How to check that your panels are really DCR

Unfortunately, some installers quote DCR prices and fit non-DCR panels, or mix the two. Protect yourself with these checks:

1. Ask for the exact model number of the panel in the quotation, not just "DCR 540 W".
2. Ask for the manufacturer's DCR certificate for that model and batch. Manufacturers issue DCR certificates for their modules, and PM Surya Ghar uses a DCR verification system linked to serial numbers.
3. Check the ALMM list on the MNRE website for the manufacturer and model. Being on ALMM alone does not prove DCR, but it is a good first check.
4. Match serial numbers. The serial numbers on the back of each panel should match the invoice and the details uploaded on the portal.
5. Get it in writing. The invoice and the work order should both say "DCR" with the model number. If the installer refuses, choose another installer.

Our checklist for choosing a genuine solar installer includes these points and more.

Red flags in quotes

• "DCR" written on the quote but no model number or manufacturer.
• A price far below other DCR quotes in your area.
• "Subsidy guaranteed" on a system that uses non-DCR panels.
• Pressure to pay the full amount before the panels are delivered.
• Claims that "ALMM does not apply to homes" when you are taking a subsidy.

What should you do now?

If you plan to claim the PM Surya Ghar subsidy, insist on DCR panels and verify them. If you are not claiming a subsidy and will be commissioned with net metering before 31 December 2026, you have more choice, but confirm with your DISCOM what they will accept at inspection. And if you are planning for 2027 or later, expect the List-II cell rule to apply more widely, so DCR panels will increasingly be the default.

Frequently asked questions

Are non-DCR solar panels banned in India?

No. Non-DCR panels can still be sold and used. They cannot be used for subsidy schemes such as PM Surya Ghar, and from 1 June 2026 projects covered by ALMM List-II must use approved cells, with a temporary exemption for net-metering and open-access projects until 31 December 2026.

Can I get the PM Surya Ghar subsidy with non-DCR panels?

No. The subsidy requires DCR panels, meaning modules made in India from Indian solar cells.

Is TOPCon better than Mono PERC?

TOPCon panels are usually slightly more efficient and lose a little less power in heat, so you can fit a bit more capacity on the same roof. Both technologies are available in DCR and non-DCR versions. For a typical home, the installer's quality and the warranty matter more than the cell technology.

Will DCR panel prices come down?

The premium narrowed after the peak in early 2026 as more Indian cell factories started production. Prices depend on supply and demand, so compare current quotes rather than relying on last year's numbers.

What happens after 31 December 2026?

Unless MNRE announces another change, net-metering and open-access projects commissioned from 1 January 2027 will also need cells from ALMM List-II manufacturers.

This guide is based on MNRE notices and industry reports available in October 2026. ALMM and DCR rules are being updated often, so confirm the latest position on the MNRE website and with your DISCOM before you buy.
