If you install rooftop solar in Kerala, two rule sets decide whether a job gets paid: the national ALMM and DCR module rules, and the Kerala net-metering rules run by KSEB. Get the module wrong and KSEB can reject the file — even after the panels are on the roof. This guide maps both for EPCs working with KSEB and KSERC, including the Soura scheme and the net-vs-net-billing question.
The short answer for Kerala EPCs
For subsidised and most government-linked net-metering work in Kerala, the module model must be on the live ALMM List-I, and DCR applies where the scheme demands it. KSEB checks the exact model and serials at approval. Your job survives only if the BOM is clean at the moment you order — not at the moment you bid.
ALMM and DCR are national rules from MNRE. Net metering is a state rule set by KSERC and run by KSEB. You must satisfy both. The metering type — net metering or net billing — also affects how your customer earns from export energy, so confirm it early.
Do Kerala jobs need ALMM-listed modules?
Yes. For subsidised work and most net-metering approvals in Kerala, the module model must appear on the live ALMM List-I. ALMM is the MNRE Approved List of Models and Manufacturers. A module is listed by its exact model number, not just the brand, so check the precise model you plan to buy.
List-I, List-II and List-III
List-I covers approved modules. List-II covers approved cells — the rule that the cells inside the module must come from an enlisted Indian maker. The List-II cell mandate had an effective date around 1 June 2026, but that date faced deferment requests and court action. Do not treat it as settled. Confirm whether it was deferred in the latest MNRE order, status as of 20 June 2026. List-III for wafers and ingots is planned for around 2028 — verify.
Why the model number matters
KSEB and the subsidy portal match the model and serial against the live list. If you order a model that was listed in your quote but delisted before delivery, the file can be rejected. Read how to check the ALMM list and check it again on the day you place the order.
KSEB and KSERC — the bodies you deal with
Kerala net metering runs almost entirely through one utility — KSEB, the Kerala State Electricity Board — under the regulator KSERC. This is simpler than states with three or four DISCOMs, but the KSEB process, fees and inspection steps still have their own quirks.
One DISCOM, one process
Because KSEB covers the whole state, you mostly deal with one portal and one document set. Confirm the live KSEB portal name and URL before you build a process around it — portal addresses change. KSERC sets the metering and tariff rules, so its latest order is the document that decides your customer payback.
The Soura scheme and DCR in Kerala
DCR is mandatory only where the scheme requires domestic content, most clearly the PM Surya Ghar residential subsidy. Kerala also runs its own rooftop programme, Soura, through KSEB. The Soura scheme rules and any DCR conditions are set by KSEB and change, so confirm the current Soura status and the DCR rule before you quote.
Subsidy vs commercial jobs
For a residential rooftop owner claiming the PM Surya Ghar subsidy, you almost always need a DCR module plus a valid DCR certificate from the NISE DCR portal. For many commercial and open-access jobs, non-DCR modules are allowed and often cheaper. See DCR vs non-DCR panels to pick the right one, and confirm the DCR rule for your exact scheme against the current MNRE order.
Net metering vs net billing in Kerala — verify this
Kerala has used both net metering and net billing for different consumer slabs, and KSERC revises the rule. The metering type changes how export energy is valued, so it directly affects payback. Treat every figure below as point-in-time. Confirm which rule applies to your customer slab against the current KSERC order before you size and quote.

The net-metering approval flow in Kerala
The KSEB flow is broadly: apply, get a feasibility check, install with a listed module and inverter, then pass a joint inspection before the meter is set. ALMM and DCR are checked at the document stage and again at inspection.
Where compliance is checked
KSEB reads your module model against the live ALMM list and, for subsidised work, your DCR certificate. At the joint inspection, the team can scan serials and match them to the listing and the certificate. A mismatch here stalls the approval. Our guide on ALMM at DISCOM approval explains exactly what they check.
Why approvals get rejected
Most rejections trace to a module or paperwork problem, not the wiring. The fixes are simple if you catch them before the order goes out.
- Model not on the live list — listed at bid time but delisted before delivery.
- Serial not found in the ALMM RFID or QR check — see the serial fix guide.
- DCR certificate mismatch — the certificate names a different model or batch than the panels.
- Wrong metering type assumed — net billing quoted as net metering, hurting payback.
- System over the cap — sized above the current limit for that consumer class.
Building a clean BOM for Kerala
A clean bill of materials is your best defence. Lock the module model, confirm it on the live ALMM list, attach the DCR certificate where needed, and record every serial before the panels leave the warehouse.
The order-day checklist
- Re-check the exact module model on the live ALMM List-I on the day you order.
- For subsidised or Soura work, confirm the DCR certificate covers the same model and batch.
- Confirm the inverter is on the KSEB and ALMM/CEA lists.
- Record module serials and keep the RFID or QR data with the file.
- Confirm whether net metering or net billing applies, and that the size fits the current cap.
Read BOM compliance for procurement for the full method, and use the compliance checklist template on every job.
How SuryaHub helps EPCs in Kerala
SuryaHub checks every module model on the BOM against the ALMM list, stores the DCR certificate and serials with the job, and tracks each KSEB net-metering and Soura file in one place. The procurement and inventory module flags a non-listed model before the order goes out, and government workflows keep each KSEB file moving. SuryaHub is pre-revenue; the real pilots are Suryantra Energy and RGESPL, and every figure here is a scheme rule to verify, not a guarantee.

Frequently asked questions
Do solar modules need ALMM listing for net metering in Kerala?+
Yes. For subsidised and most government-linked net-metering work in Kerala, the module model must sit on the live ALMM List-I. KSEB can check the exact model number at approval. Always verify the model on the current MNRE ALMM list before you order, because models are added and removed often.
Is DCR mandatory for solar under the Soura scheme and PM Surya Ghar in Kerala?+
DCR is mandatory where the scheme requires domestic content, most clearly the PM Surya Ghar residential subsidy. The Kerala Soura scheme rules and DCR conditions are set by KSEB and change. Confirm the current Soura status and DCR rule against KSEB and the latest MNRE order before you quote.
Does Kerala use net metering or net billing?+
Kerala has used both net metering and net billing for different consumer slabs, and KSERC revises the rule. The metering type changes how export energy is valued, so it affects payback. Confirm whether net metering or net billing applies to your customer slab against the current KSERC order before you quote.
Which DISCOM and regulator run net metering in Kerala?+
KSEB is the state-wide distribution utility that runs net metering in Kerala, under the regulator KSERC. Unlike larger states, Kerala mostly works through one DISCOM. Confirm the live KSEB portal, the application steps and the current fee with KSEB before you build a process around them.
Can an ALMM-listed module still be rejected by KSEB?+
Yes. A module can be ALMM-listed yet still be rejected by KSEB if the serial does not match the listing, the model was delisted after you bought it, or the DCR certificate names a different model. KSEB verifies the exact model and serials, so check the live list at the moment you order.
How does SuryaHub help solar EPCs in Kerala?+
SuryaHub checks every module model on the BOM against the ALMM list, stores the DCR certificate and serials, and tracks each KSEB net-metering and Soura file in one place.
