Featured Snippet Answer
From 1 June 2026, net-metering and open-access solar projects commissioned on or after that date must use solar modules listed on MNRE ALMM List-I and solar cells listed on ALMM List-II. MNRE did not grant a blanket extension, but case-by-case relief was allowed for projects with substantial pre-deadline progress, claimed through the National Institute of Solar Energy portal with documentary proof.
Quick Summary Box
What it is
The MNRE Approved List of Models and Manufacturers rule that extended domestic sourcing requirements from solar modules to solar cells for covered projects from 1 June 2026.
Who it is for
anyone commissioning a net-metering or open-access solar project in India during or after mid-2026
Main benefit
It closes the loophole where imported cells were assembled into locally branded modules, which protects subsidy claims, warranty quality and long-term performance.
Key risk
Off-list modules or cells can fail DISCOM inspection and forfeit subsidy eligibility, and a model delisted mid-installation can leave the buyer absorbing the loss.
Typical cost
Reports through 2026 indicated domestic module prices had moved to roughly Rs 25 to Rs 27 per watt from about Rs 21 to Rs 22 per watt as the domestic cell rule tightened. Analysts estimated solar tariffs could rise by about 40 to 50 paise per unit in the near term until local cell capacity scaled up.
Best next step
Before paying any advance, ask your vendor for the module List-I registration and the cell List-II registration for the exact models quoted, and verify both on the current MNRE list.
Introduction
For years, India required solar modules to come from approved domestic manufacturers, but the cells inside those modules could be imported. Vendors could assemble imported cells here and still sell the panel under a domestic brand.
ALMM List-II closed that gap for covered projects. From 1 June 2026, the cells inside qualifying modules must also come from approved domestic makers. The rule is short, but it changes quotes, timelines and risk for anyone installing rooftop solar.

How ALMM List-II solar cell rule Works in India
ALMM List-II solar cell rule should be decided from your real Indian site conditions, not from a brochure number. The practical answer depends on tariff, approval, wiring or roof condition, equipment warranty and how you will use the system month after month.
For homeowners, housing societies, EPC vendors and commercial solar buyers, the useful approach is to convert the topic into a short checklist: what is being installed or compared, who approves it, what it costs, how it is metered or warranted, and what happens if something fails.
- ALMM List-I covers solar modules and had already applied to many government-linked schemes.
- ALMM List-II covers solar cells and became mandatory for applicable projects from 1 June 2026.
- Covered categories include net-metering projects and open-access renewable energy projects commissioned on or after 1 June 2026.
- MNRE did not grant a blanket extension, though case-by-case relief was available with documentary proof.
- Relief claims were routed through the National Institute of Solar Energy portal, with a submission window closing 30 June 2026.
- Domestic module prices rose in 2026, with trade reports citing roughly Rs 25 to Rs 27 per watt against an earlier Rs 21 to Rs 22 per watt.
- Subsidy-linked systems also need a vendor registered on the national portal for the relevant DISCOM.
Decision Factors That Actually Matter
A good decision starts with the constraint that can stop the project: load, parking, roof rights, net-metering rule, vendor quality or battery warranty. Once that is clear, the cost comparison becomes far more reliable.
Do not optimise only for the headline number. A cheap charger with poor protection, a solar quote with weak structure, a battery claim without warranty clarity, or a subsidy promise without portal status can cost more later.
- Check the official rule or warranty document first.
- Use your own electricity bill, kilometres, roof area or battery report.
- Ask for itemised hardware, labour, tax and maintenance costs.
- Keep written approvals and invoices before routine use.
Costs, Savings and Payback Logic
For 2026 planning, use the numbers that are actually being quoted in the market instead of older blog figures. ALMM-compliant residential rooftop solar is broadly Rs 40,000 to Rs 55,000 per kW (Rs 40 to Rs 55 per watt) all-in in 2026, compared with roughly Rs 55,000 to Rs 65,000 per kW in 2023. Domestic module prices moved to about Rs 25 to Rs 27 per watt from about Rs 21 to Rs 22 per watt as the ALMM List-II cell rule took effect from 1 June 2026. The central PM Surya Ghar subsidy is unchanged at Rs 30,000 per kW for the first 2 kW and Rs 18,000 per kW for the third kW, capped at Rs 78,000.
For payback, use conservative assumptions. Count real monthly units or kilometres, charging losses, export value, maintenance and loan EMI. If the page involves policy or subsidy, calculate both with and without subsidy so the project still makes sense if processing is delayed.
| Cost item | Practical planning note |
|---|---|
| One-time cost | Reports through 2026 indicated domestic module prices had moved to roughly Rs 25 to Rs 27 per watt from about Rs 21 to Rs 22 per watt as the domestic cell rule tightened. Analysts estimated solar tariffs could rise by about 40 to 50 paise per unit in the near term until local cell capacity scaled up. |
| Running cost or saving | For 2026 planning, use the numbers that are actually being quoted in the market instead of older blog figures. ALMM-compliant residential rooftop solar is broadly Rs 40,000 to Rs 55,000 per kW (Rs 40 to Rs 55 per watt) all-in in 2026, compared with roughly Rs 55,000 to Rs 65,000 per kW in 2023. Domestic module prices moved to about Rs 25 to Rs 27 per watt from about Rs 21 to Rs 22 per watt as the ALMM List-II cell rule took effect from 1 June 2026. The central PM Surya Ghar subsidy is unchanged at Rs 30,000 per kW for the first 2 kW and Rs 18,000 per kW for the third kW, capped at Rs 78,000. |
| Payback logic | Payback improves when monthly use is high, tariff is high, equipment is correctly sized and avoidable rework is prevented. |
| Hidden cost to check | DISCOM charges, cable route, structure, protection devices, app fees, maintenance and warranty exclusions. |
Best Fit by User Type
Homeowners should prioritise safety, long-term running cost and serviceability. Apartment residents should prioritise written approval, cable route and billing clarity. Fleet operators should prioritise uptime, utilisation and load management. First-time buyers should prioritise total cost, warranty and practical access.
The right answer is usually the option that is easiest to operate every week, not the one that looks most impressive in a quote.
- Independent house: easier wiring or roof access, but still needs load and safety checks.
- Apartment: approval, metering and route discipline matter as much as equipment.
- Fleet or business: utilisation and downtime decide economics.
- First-time buyer: choose the simplest reliable option before adding advanced features.
Safety, Compliance and Documentation
For EV charging and solar, the safety chain includes correct equipment, installation method, protection devices, earthing, isolation, waterproofing where needed and clear ownership of maintenance. For batteries, it includes temperature control, charger behaviour, warranty compliance and service diagnostics.
Keep documents boring and complete: invoice, datasheet, warranty, approval, inspection record, photos and portal acknowledgement. Boring paperwork is what saves time when a society, DISCOM, insurer or service centre asks questions later.
- Verify current official rules before payment.
- Use qualified installers for electrical work.
- Do not bypass safety devices or approval conditions.
- Review the setup after the first month of actual use.
Pros and Cons
Pros
- Can reduce confusion around ALMM List-II solar cell rule with a clear decision path.
- Helps compare cost, safety, approval and warranty in one place.

Step-by-Step Guide
-
1
Confirm which rule applies to your project
ALMM List-II applies to net-metering and open-access projects commissioned on or after 1 June 2026. Projects commissioned earlier may fall under the earlier rules, so confirm your commissioning route and dates in writing.
-
2
Ask for both registration numbers
Request the List-I module registration and the List-II cell registration for the exact model quoted. A generic claim of ALMM compliance is not enough documentation.
-
3
Verify on the official MNRE list
Cross-check model numbers on the current MNRE ALMM list rather than relying on a screenshot, brochure or dated certificate supplied by the vendor.
-
4
Check the vendor portal registration
For subsidy-linked rooftop systems, the installer must be registered on the national portal for your DISCOM. An unregistered vendor blocks the application at the feasibility stage.
-
5
Budget for higher module cost
Assume a higher Rs per watt than older blog figures. Compare quotes on an all-in basis that includes GST, structure, cables, earthing, net-metering charges and commissioning.
-
6
Keep documentary proof
Retain invoices, datasheets, registration certificates and geo-tagged photos. If a listing changes later, proof of what was supplied at the time is what protects your claim.
Common Mistakes
- Deciding ALMM List-II solar cell rule from a single YouTube video, vendor claim or neighbour example.
- Ignoring sanctioned load, roof rights, cable route, meter type or warranty wording.
- Comparing only upfront price and not service, safety, warranty and maintenance.
- Using outdated subsidy, tariff or policy screenshots.
- Paying a large advance before portal status, written approval or itemised quote.
- Assuming the same rule applies across all Indian states and DISCOMs.
- Forgetting to keep invoices, photos, datasheets and approval records.
- Treating temporary charging, temporary wiring or verbal approval as permanent.

What is ALMM List-II?
ALMM is the MNRE Approved List of Models and Manufacturers. List-I covers solar modules, while List-II covers solar cells. From 1 June 2026, covered projects must use modules from List-I and cells from List-II, both from approved domestic makers.
Does ALMM List-II affect the PM Surya Ghar rooftop subsidy?
ALMM List-I for modules had applied to many government-linked schemes for years, and List-II extends compliance to cells from June 2026. Rooftop and net-metering projects tied to central or state incentives should use only ALMM-listed equipment. Confirm model numbers on the current MNRE list before purchase.
Did on-grid solar become more expensive after June 2026?
Reports through 2026 indicated domestic module prices moved to roughly Rs 25 to Rs 27 per watt from about Rs 21 to Rs 22 per watt, and analysts estimated solar tariffs could rise by about 40 to 50 paise per unit in the near term until local cell capacity scaled. Actual quotes vary by state, DISCOM and vendor, so use written quotations.
Was there any extension to the 1 June 2026 deadline?
MNRE ruled out a blanket extension, but case-by-case relief was available for projects with substantial progress before the deadline. Claims were submitted through the National Institute of Solar Energy portal with documentary proof, with a window that closed on 30 June 2026.
What should I check in a vendor quote for ALMM compliance?
Ask for the List-I module registration and the List-II cell registration for the exact model, the vendor portal registration ID for your DISCOM, an itemised all-in price including taxes and net-metering charges, and the written warranty terms for both module and inverter.
Is ALMM List-II solar cell rule worth it in India in 2026?
ALMM List-II solar cell rule is worth considering when it solves a real cost, access, safety or approval problem in your situation. Do not decide from a national average alone. Check your monthly units, parking access, DISCOM tariff, roof condition, warranty terms and the written approval process that applies to your city or society.
What should I verify before acting on this guide?
Verify the latest official source, your DISCOM or society process, equipment warranty, safety requirements and all costs in writing. For solar and subsidy pages, use the official PM Surya Ghar or state portal. For EV charging, confirm sanctioned load, earthing, protection devices and cable route with a qualified electrician.
Can a calculator replace a vendor inspection?
No. A calculator is useful for first-pass sizing, cost and payback. Final installation needs a site visit, load check, roof or parking inspection, equipment datasheets and local approvals. Treat calculators as decision support, not as an electrical design certificate or a subsidy approval guarantee.

"acceptedAnswer": {
"@type": "Answer",
"text": "ALMM List-II solar cell rule is worth considering when it solves a real cost, access, safety or approval problem in your situation. Do not decide from a national average alone. Check your monthly units, parking access, DISCOM tariff, roof condition, warranty terms and the written approval process that applies to your city or society."

"@type": "Question",
"name": "What should I verify before acting on this guide?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Verify the latest official source, your DISCOM or society process, equipment warranty, safety requirements and all costs in writing. For solar and subsidy pages, use the official PM Surya Ghar or state portal. For EV charging, confirm sanctioned load, earthing, protection devices and cable route with a qualified electrician."

{
"@type": "Question",
"name": "Can a calculator replace a vendor inspection?",
"acceptedAnswer": {
"@type": "Answer",
"text": "No. A calculator is useful for first-pass sizing, cost and payback. Final installation needs a site visit, load check, roof or parking inspection, equipment datasheets and local approvals. Treat calculators as decision support, not as an electrical design certificate or a subsidy approval guarantee."
