ALMM rarely comes up until an installation gets stuck at the inspection stage — and by then, the panels are already on the roof. Understanding it before you buy modules saves a lot of expensive rework.
This guide covers what ALMM is, why it matters for subsidy eligibility, and how to check a panel's certification before you commit to it.
What Is ALMM?
The Approved List of Models and Manufacturers (ALMM) is a government-maintained registry of solar panel manufacturers and models cleared for use in subsidised and government-linked solar projects. It exists to keep low-quality, uncertified panels out of publicly-funded installations.
Why It Matters for Subsidy Claims
Under PM Surya Ghar and most other government solar programmes, using a non-ALMM panel isn't a minor technicality — it's grounds for the DISCOM to reject the installation outright during inspection.
- •The subsidy claim gets rejected even if the system is fully installed and generating power.
- •The homeowner may need to swap out the panels entirely to reapply, at their own cost.
- •The vendor's DISCOM empanelment can be flagged for repeated non-compliance.
List I vs List II
ALMM covers two categories: List I for solar PV modules and List II for solar cells. Most residential rooftop projects only need to worry about List I, since cells are a component-level certification that matters more to manufacturers than installers.
How to Check If a Panel Is ALMM-Certified
Before you sign off on a vendor's panel choice, verify it directly rather than taking their word for it:
- 1.Ask the vendor for the exact manufacturer name and model number, not just the brand.
- 2.Check the model against the current ALMM List I published by MNRE.
- 3.Confirm the listing hasn't expired — ALMM approvals are time-bound and get renewed periodically.
- 4.Keep a copy of the listing with your installation paperwork in case a DISCOM asks for proof during inspection.
How ZEP360 Keeps Vendors on the Right Side of ALMM
ZEP360's project setup flags non-ALMM equipment before a purchase order ever goes out, not after a failed inspection. For EPCs running multiple installation teams, that single check prevents the single most expensive kind of rework: pulling panels off a roof that's already been installed.
Frequently Asked Questions
Does ALMM apply to inverters too?
Inverters are covered under a separate MNRE-approved list, not ALMM itself — but the same principle applies: non-approved inverters can also cause a subsidy claim to be rejected.
Can imported solar panels be ALMM-certified?
Yes, if the manufacturer has applied for and received ALMM listing for that specific model — origin isn't the deciding factor, certification is.
What if I already installed non-ALMM panels?
You can still use the system, but it won't qualify for a government subsidy claim under PM Surya Ghar or similar schemes — the panels would need to be swapped for a certified model to become eligible.
