DCR vs Non-DCR Panels and ALMM: What the 2026 List-II Shift Means

Two quotations for the same 5 kW home system or 100 kW business plant can have very different module costs. Before choosing the lower figure, check where its cells were made and whether the proposed model appears on the current MNRE approved lists. A lower hardware price will mean little if the equipment cannot pass the approvals your project needs.

DCR and ALMM answer different questions. DCR tells you about Indian content in the cell and finished module. ALMM identifies approved manufacturers and models. The distinction now matters beyond subsidised home systems because the June 2026 List-II compliance shift also affects new commercial and industrial grid projects.

Ask each installer for the exact module model, cell source, serial traceability and the approval basis used in the quotation. That gives you a fairer comparison of price, eligibility and commissioning risk before you place an order.

What DCR and ALMM each mean

A solar module contains cells connected and sealed between protective layers, usually glass and a backsheet, inside an aluminium frame. The cells turn sunlight into electricity. Assembling those parts in India does not, by itself, mean the cells were made here.

Some Indian factories have long used imported silicon cells to assemble finished modules. This is Indian module manufacture, but it does not meet a requirement for Indian cells as well. The two policy terms help you identify exactly what you are buying:

Domestic Content Requirement (DCR): Both the photovoltaic cells and the completed module must be manufactured in India. Ask for the manufacturer's DCR evidence linked to the module and cell serial numbers.

Approved List of Models and Manufacturers (ALMM): MNRE maintains approved lists for eligible equipment. The applicable list and project rules must be checked against the model in your quotation, not merely against a brand name.

How ALMM List-I and List-II apply

The lists follow the two manufacturing stages. A proposal that identifies only the assembled module leaves the cell origin unanswered.

• ALMM List-I, modules: This covers approved module manufacturers and models. The module factory is inspected for manufacturing capacity and quality; the National Institute of Solar Energy (NISE) is involved in that assessment.
• ALMM List-II, cells: This covers approved cell manufacturers. It lets you verify the source of the photovoltaic cells inside the module rather than relying on the assembly location.

Before the June 2026 List-II transition, many commercial and industrial projects used List-I modules assembled from imported cells. The newer compliance position requires closer checking of domestic cell content for grid-connected C&I work. Ray2Volt therefore prepares new business quotations with DCR panels unless a project has a verified exemption. Confirm the project's specific DISCOM, net-metering or open-access conditions before ordering.

Allow for the DCR module price premium

The price difference comes mainly from the cell supply chain. Indian module assembly has grown faster than domestic cell fabrication. A cell factory needs expensive equipment, controlled manufacturing conditions and a dependable wafer supply. Imported cells may therefore make a cheaper assembled panel, depending on the brand and purchase date.

Use roughly ₹9 to ₹12 per Wp, or ₹9,000 to ₹12,000 per kWp, when checking a DCR quotation against a comparable non-DCR one. At 3 kW, that is about ₹27,000 to ₹36,000 of extra module cost. A qualifying 3 kW home installation can receive up to ₹78,000 under PM Surya Ghar, so compare the complete installed cost after the applicable subsidy. A site audit and actual quotes are needed before deciding which option costs your household less.

MNRE capacity data has put Indian module assembly above 40 GW. That figure changes; check the latest MNRE publication if production scale affects your purchase. Ask the vendor to document the cells used in the exact modules delivered to your site.

DCR rules for homes and businesses

Start with the connection category. The PM Surya Ghar grant applies to an eligible domestic residential connection. A commercial or industrial electricity connection cannot claim that residential benefit.

Home installations under PM Surya Ghar

For a qualifying home system, the central assistance is ₹30,000 at 1 kW, ₹60,000 at 2 kW and capped at ₹78,000 from 3 kW upwards. The scheme implementation period runs to 31 March 2027. Every subsidised module must satisfy DCR requirements, with its serial numbers documented on the portal. Non-DCR modules make the installation ineligible, even if their performance looks similar on paper.

Commercial and industrial installations

Businesses do not receive the home subsidy. Their grid-connected projects still need equipment that meets the ALMM and DISCOM conditions applicable to the project. Imported-cell proposals can encounter a problem at net-metering or open-access approval after the June 2026 List-II shift unless a verified exemption applies. Have the EPC contractor confirm the approval route in writing before procurement.

Compare panel quality separately from origin

Indian manufacture does not tell you whether a panel uses old or new cell technology. You can buy domestic modules built with N-type TOPCon or Mono PERC cells. Compare the specific model's test data, warranty and expected generation, rather than assuming an imported cell must perform better.

Some current modules are quoted with efficiencies around 21.5% to 22.5%, but the actual figure depends on the model. Ask for its datasheet, flash test report, temperature coefficient and degradation terms. Low-light output during cloudy weather and heat losses during Andhra Pradesh summers can matter more to your bill than a broad technology label.

Our guide to Mono PERC, TOPCon and bifacial panels explains N-type cells and half-cut layouts if you want to compare equipment more closely.

Documents to check before ordering panels

Put the compliance check into the purchase process. It is easier to correct a quotation than to replace modules after a DISCOM inspection.

1. Trace the DCR claim: Request the manufacturer's certificate, module and cell serial references, and flash test reports. Make sure the delivery matches the approved model.
2. Match the grid application: Have your EPC partner show how the submitted drawings and equipment documents meet the applicable ALMM List-I, List-II and local DISCOM requirements.
3. Compare the whole project cost: A claimed ₹2 per Wp saving on unsuitable equipment can be outweighed by rework and approval delays. See our factory solar guide for other installation decisions.
4. Choose the ownership model: A business may buy its plant under CAPEX or consider a third-party power arrangement. Our CAPEX and RESCO comparison sets out those choices.

A correctly oriented roof in the Tirupati, Puttur or Srikalahasti area may produce roughly 4 to 4.5 units per kW per day on an annual average, or about 1,400 to 1,600 units per kW a year. Plan for about 80 to 100 sq ft of shade-free roof per kW. These are sizing guides; shading, layout and equipment losses need a site audit.
