India's solar energy ambition — 500 GW of renewable capacity by 2030 — rests on one foundational question: where do the panels come from, and are they good enough? The ALMM is MNRE's answer.
01 / INTRODUCTIONWhat is ALMM and Why Does It Exist?
The Approved List of Models & Manufacturers (ALMM) is a regulatory framework introduced by MNRE. The first List-I (modules) was published on March 10, 2021.
Only manufacturers whose products appear on this list are eligible to supply solar modules and cells for government projects in India.
Before ALMM, India's solar sector was flooded with low-quality imports. ALMM creates accountability.
The Three-Layer ALMM Architecture
MNRE has structured ALMM as a progressive supply-chain framework with three lists coming into force over time:
| List | Covers | First Published | Mandatory From | Status |
|---|---|---|---|---|
| List-I | Solar PV Modules | March 10, 2021 | April 10, 2021 | ✓ Active |
| List-II | Solar PV Cells | July 31, 2025 | June 1, 2026 | ⏳ Transition |
| List-III | Solar PV Wafers | Expected 2028 | June 1, 2028 (draft) | 📝 Draft |
"The ALMM is not just a quality list — it is the single most powerful lever India has used to indigenise its solar supply chain."

02 / LIST-IApproved Module Manufacturers — 144 GW and Growing
As of December 22, 2025, ALMM List-I covers 100+ module manufacturers with a combined enlisted capacity of 144,841 MW (~145 GW).
December 2025 saw a record single-month addition of 23,119 MW, with six new manufacturers entering.
Minimum Efficiency Thresholds
| Category | Application | Min Efficiency | Technology |
|---|---|---|---|
| Category I (Utility) | Ground-mount, large-scale | ≥ 20.0% | Mono c-Si |
| Category II (Rooftop) | Commercial / Industrial rooftop | ≥ 19.5% | Mono c-Si |
| Off-Grid | Solar lamps, fans, lights | Lower threshold (amended) | Any |
03 / LIST-IIApproved Cell Manufacturers — The New Frontier
ALMM List-II for solar PV cells is India's next strategic frontier. First published on July 31, 2025, it currently covers 10 manufacturers with a combined capacity of 26,790 MW. The mandate becomes compulsory from June 1, 2026.
Projects bid on or before Aug 31, 2025: ALMM List-II not mandatory.
After Aug 31, 2025: Must comply with List-II.

| 10 | Evervolt Solar Technology India | Mono PERC Bifacial | 1,074 MW | Andhra Pradesh |
04 / MANUFACTURERSTop 10 ALMM Manufacturers You Must Know
The top five players account for roughly 45% of all enlisted module capacity.
05 / COMPLIANCEWho Must Comply with ALMM?
ALMM compliance applies to specific categories of projects.
Private off-grid installations; captive consumption; projects commissioned before March 31, 2024.
06 / TIMELINEKey Regulatory Dates You Cannot Afford to Miss
MNRE issues the founding legal document.
MNRE publishes the first ALMM List-I for solar PV modules.
After a year-long hold, MNRE reinstates the ALMM mandate.
India's first approved list for solar PV cells is published.
ALMM List-II for solar cells becomes compulsory.
MNRE's draft amendment proposes ALMM List-III for solar wafers.
07 / TECHNOLOGYPERC vs TOPCon vs HJT — What's on ALMM?
The technology mix within ALMM has shifted dramatically since 2021 — from polycrystalline to Mono PERC to TOPCon.
| Technology | Typical Efficiency | ALMM Share | Key ALMM Manufacturers | Best For |
|---|---|---|---|---|
| Mono PERC | 19.5%–21.5% | ~59% | Waaree, Tata, Adani, ReNew, Premier | Rooftop, cost-sensitive utility |
| TOPCon | 21.5%–23.5% | ~28% | Waaree, Adani, Emmvee, Rayzon, Goldi | Utility-scale, carport, BIPV |
| HJT | 22%–24%+ | <1% | Vikram Solar (limited) | Premium, space-constrained |
| CdTe Thin Film | 18%–19% | ~2% | First Solar (FS India) | Utility, arid/high-irradiance zones |
| Bifacial (any) | +5–15% rear gain | ~60% modules | Most major manufacturers | Ground-mount, tracker systems |
TOPCon pricing has converged with Mono PERC. Recommend TOPCon bifacial for utility-scale tenders above 500 kWp.
08 / SOURCINGHow to Source ALMM-Certified Modules Effectively
Knowing the list is only half the battle. The real challenge is securing the right modules.

Q: Can a private rooftop solar project use non-ALMM modules?
Yes — if the project is entirely off-grid or used for captive consumption without any government subsidy.
Q: What happens if a manufacturer is delisted mid-project?
Previously installed modules remain compliant. Future supply must come from an active listed manufacturer.
Q: Is First Solar's thin-film module ALMM-listed?
Yes. FS India Solar Ventures has 3,433 MW of CdTe thin-film capacity listed.
Q: How often is the ALMM list updated?
MNRE updates List-I approximately every 4–6 weeks.
Q: Where can I download the official ALMM list PDF?
The official ALMM list is available at mnre.gov.in.
