- For subsidy work, ALMM net metering DISCOM checks are linked — a non-ALMM module can get net-metering rejected.
- DISCOMs check ALMM at two points: feasibility/approval and the site inspection.
- At inspection, the inspector reads the module serial / RFID to confirm panels match the approved model.
- DCR kicks in for subsidy or DCR-linked schemes, checked via the NISE DCR portal.
- How it is applied varies by state — verify with the state DISCOM/SERC.
- Fix the model on your BOM before the DISCOM checks, not after a rejection.
If you do subsidised rooftop work, the ALMM net metering DISCOM link is the quiet gate that decides whether your project gets grid approval. Many DISCOMs now match your solar module against the ALMM list when they process net-metering. Pick the wrong module and the whole application stalls.
This guide is for EPC owners and ops teams. It explains how DISCOMs check ALMM (and sometimes DCR) at net-metering, why a non-ALMM module gets rejected, what the serial and RFID check looks for at inspection, how it varies by state, and what to keep on file. For the wider context, see our ALMM & DCR hub and the full net-metering hub.
Why does ALMM gate net-metering approval?
ALMM gates net-metering because, for government-subsidy projects, the DISCOM is told to use only modules on the approved list. ALMM is the Approved List of Models and Manufacturers, run by MNRE. It is a national list of solar modules cleared for use in supported schemes.
Net-metering is the permission to connect your system to the grid and export power. It is granted by the state DISCOM under rules set by the State Electricity Regulatory Commission (SERC). So you have two systems meeting at one job: a national module list and a state grid permission. For subsidy work, the DISCOM uses the first to approve the second.
The two authorities you are dealing with
MNRE owns ALMM. Your state DISCOM owns net-metering. Neither talks to the other in real time, so the burden of matching them falls on you, the EPC. If your module is not ALMM-listed, the DISCOM has a clean reason to reject the net-metering file — and you only find out late.
How do DISCOMs check ALMM during net-metering?
DISCOMs check ALMM by matching the module make and model on your application against the current ALMM List-I. The check is simple: your bill of materials names a module, and the reviewer looks for that exact make-model on the list.
The make-model match
The match must be exact. A model that is "close" or an older variant of a listed model can still be flagged. DISCOMs increasingly ask for the ALMM reference or registration detail with the application, not just a brand name. A vague entry like "550W mono PERC" is not enough.
Why the match fails on paper
Common paper failures: the model on the quote differs from the model on the invoice; the panel delivered to site is a newer batch with a slightly different model code; or the listing lapsed between quoting and applying. Any of these breaks the match and gives the DISCOM grounds to return the file.
Is ALMM checked at feasibility or at inspection?
Most DISCOMs check ALMM at both stages — first on paper at feasibility or approval, then physically at site inspection. Treating it as a one-time check is a common mistake that costs EPCs time.
The feasibility / approval check
At feasibility, the DISCOM reviews your application before any wiring. They confirm the proposed module is ALMM-listed and, for subsidy work, that it meets the scheme rules. Clear this stage and you get the go-ahead to install. Fail it and you fix the module before you spend on hardware.
The site inspection check
After install, an inspector visits the site. They confirm the panels physically on the roof match the approved ALMM model. This is where the serial and RFID check happens, covered below. A mismatch here is worse than a paper mismatch — the panels are already up.
The net-metering hub has the full grid-approval sequence; see the net-metering hub for feasibility, agreement, inspection and meter steps in order.
Why does a non-ALMM module get net-metering rejected?
A non-ALMM module gets rejected because the DISCOM is not allowed to approve subsidy net-metering on a module outside the approved list. It is a rule-bound rejection, not a judgement call, so arguing rarely helps.
The rejection is rule-bound
For a government-subsidy project, the scheme conditions usually require an ALMM-listed module. If the module is not listed, the reviewer has no discretion — they return the file. The fix is to change the module, not to appeal the decision.
What a rejection costs you
A late rejection can mean re-procuring panels, redoing the BOM, refiling the application, and explaining a slipped date to the customer. If panels are already installed, you may have to swap them. The cheapest fix is to never let a non-ALMM model onto the BOM in the first place. For a step-by-step recovery, see net-metering rejected on ALMM.
What is the serial / RFID check at inspection?
The serial and RFID check is how the inspector confirms the actual panels on the roof are the ALMM-listed (and, for DCR, DCR-registered) modules you declared. They read each module nameplate and serial number, and for DCR projects they scan the RFID tag.
Reading the nameplate and serials
Every module has a nameplate with make, model, wattage and a unique serial number. The inspector records these and matches them to your approved model and your serial list. If a serial does not match — for example a substituted panel — it gets flagged on the spot.
The DCR RFID tag
DCR modules are registered on the NISE DCR portal, and many carry an RFID tag tied to that registration. For DCR-linked subsidy work, the inspector or the portal cross-checks the RFID or serial against the registry. A panel that is not registered as DCR will not pass a DCR inspection, even if it is otherwise ALMM-listed.
Keep your serial list ready
Have the full serial-number list for the installed panels ready before the inspector arrives. A clean, matching list makes the inspection quick. A missing or mismatched list turns a 20-minute check into a re-visit.
When does DCR also apply, not just ALMM?
DCR applies on top of ALMM when the project uses a government subsidy or a DCR-linked scheme. DCR means Domestic Content Requirement — the cells and modules must be made in India. ALMM says the model is approved; DCR says the content is domestic.
ALMM vs DCR — they are not the same
A module can be ALMM-listed but not DCR. ALMM List-I is about model approval. DCR is about where the cell and module are manufactured. Subsidy schemes often require both: an ALMM-listed model that is also DCR-compliant and registered on the NISE DCR portal.
The List-II cell-mandate point
MNRE has been moving toward an ALMM List-II for solar cells, with a model mandate that would require domestically made cells from a target date around 1 June 2026. That move was litigated and a deferment was requested, including in the Karnataka High Court. So do not treat it as settled — confirm whether it was deferred in the latest MNRE order, status as of 20 Jun 2026. For the filing path, see List-II extension via the DCR portal, and for scope, which projects must comply.
How does it vary state by state?
It varies because ALMM is national but net-metering is run by each state DISCOM under its own SERC. The table below shows how a few major DISCOMs commonly handle the check. Every cell is point-in-time — verify with the state DISCOM/SERC before you rely on it.
Point-in-time as of 20 Jun 2026. Source: state DISCOM / SERC and MNRE ALMM order. Verify with the state DISCOM/SERC.
The pattern is consistent even if the detail differs: for subsidy work, ALMM is checked, DCR tracks the scheme, and the check happens at both feasibility and inspection. The state-specific twists are in the timing and the paperwork. Always confirm with the DISCOM that runs your job.
What should you keep on file for the ALMM check?
Keep the module ALMM reference, the datasheet, the serial list, any DCR/RFID record, and the supplier invoice — one matched set per job. If these line up, both the feasibility check and the inspection go fast.
- ALMM List-I reference — the make-model entry, with the registration detail if asked.
- Module datasheet — matching the exact model on your BOM and invoice.
- Serial-number list — every installed panel, matched to the approved model.
- DCR registration / RFID record — for subsidy or DCR-linked schemes, from the NISE DCR portal.
- Supplier invoice — model code on the invoice identical to the quote and the BOM.
The single biggest cause of trouble is a model that changes between quote, invoice and delivery. Lock the model early and check that every document names the same thing.
How does SuryaHub help with ALMM net-metering?
SuryaHub helps by enforcing the ALMM-listed model on your bill of materials before the DISCOM ever checks it. The idea is to catch a non-ALMM or non-DCR module at procurement, not after a rejection. SuryaHub plans to flag the module against the approved model on the BOM, and keep serials, DCR records and net-metering steps in one place per job.
That means your procurement and inventory stays tied to the approved model, and your government workflows carry the same module through feasibility, agreement and inspection. One source of truth across the team, so the field crew installs exactly what the DISCOM approved.
Honest note: SuryaHub is pre-revenue, and the automatic ALMM/DCR checks described here are on the roadmap, not all shipped today. The only real pilots are Suryantra Energy and RGESPL. ALMM lists, DCR rules and per-state DISCOM checks are point-in-time and vary by state — verify with the state DISCOM/SERC and the current MNRE order.

Frequently asked questions
Does ALMM affect net metering approval?+
Yes. Many DISCOMs check ALMM at the net-metering feasibility or approval stage. If your solar module is not on the ALMM List-I, the DISCOM can reject the net-metering application for a government-subsidy project. The rule is point-in-time and varies by state, so verify with the state DISCOM and SERC.
Why was my net-metering application rejected on ALMM grounds?+
Your net-metering application was likely rejected because the module model on your bill of materials is not on the current ALMM List-I, or the make and model did not match. DISCOMs cross-check the module against ALMM for subsidy work. Swap to an ALMM-listed model and refile with the state DISCOM.
Where does the DISCOM check ALMM — at feasibility or inspection?+
Most DISCOMs check ALMM at two points. First, at feasibility or application, they match your module make and model against ALMM List-I. Second, at site inspection, the inspector reads the module serial numbers and nameplate to confirm the installed panels match the approved ALMM-listed model.
Does DCR apply to net metering?+
DCR applies to net metering when the project uses a government subsidy or a DCR-linked scheme. For those projects, DISCOMs may ask for DCR modules registered on the NISE DCR portal, checked by serial or RFID. For purely private rooftop work without subsidy, DCR usually does not apply. Confirm with your state DISCOM.
What should I keep on file for an ALMM net-metering check?+
Keep the module ALMM List-I reference, the make-model datasheet, the module serial-number list, any DCR portal registration or RFID record, and the supplier invoice. Match every serial to the installed panels. Having this ready speeds up both the feasibility check and the site inspection by the DISCOM.
Is the ALMM rule the same in every state?+
No. ALMM itself is a national MNRE rule, but how each DISCOM applies it at net-metering varies by state. Some check it strictly at feasibility, others mainly at inspection. DCR requirements also differ by scheme. Treat any state detail as point-in-time and verify with the state DISCOM and SERC.
How does SuryaHub help with ALMM net-metering compliance?+
SuryaHub enforces the ALMM-listed model on your bill of materials before the DISCOM ever checks it, and keeps module serials, DCR records and net-metering steps in one place per job. SuryaHub is pre-revenue; the AI checks are on the roadmap, and the only real pilots are Suryantra Energy and RGESPL.
