India crossed 150 GW of installed solar capacity in early 2026 — and the government is now tightening one rule that affects almost every Kerala homeowner applying for rooftop solar or PM Surya Ghar subsidy: panels must be on the Approved List of Models and Manufacturers (ALMM), with domestic content requirements (DCR) for subsidised systems.

What Is ALMM — and Why Does It Matter Now?

ALMM is MNRE's official list of solar panel models and manufacturers approved for government-linked projects in India. From June 2026, new grid-connected solar installations are expected to use ALMM-listed modules. For residential buyers under PM Surya Ghar, using non-listed or non-DCR-compliant equipment can disqualify you from the central subsidy of up to ₹78,000.

The policy goal is straightforward: strengthen India's solar manufacturing (now among the world's largest), reduce dependence on imported modules for subsidised rooftops, and improve traceability when something goes wrong with a system.

Not a Price Hike — a Quality and Compliance Shift

India's module manufacturing capacity exceeded 140 GW in 2026. Domestic supply is abundant and competitively priced. ALMM is mainly about which panels qualify for subsidy and grid connection — not about abandoning solar economics.

What Kerala Buyers Should Verify Before Signing

  • Model name on your quotation matches an entry on the current ALMM list (check MNRE's published list or ask your installer to show the listing).
  • Invoice and warranty documents name the same manufacturer and model — important for subsidy release and future claims.
  • Installer is MNRE-approved and registers your project correctly on the national portal; non-compliant hardware is a common reason for subsidy delays.
  • Do not accept "import panels at lower cost" for a subsidised residential job unless your installer confirms full compliance — the savings rarely outweigh losing ₹78,000.

How This Fits Kerala's 2026 Solar Picture

Kerala added rooftop capacity at roughly 55% year-on-year growth in FY26 — driven by high KSEB tariffs, strong awareness, and PM Surya Ghar. As demand accelerates, regulators and DISCOMs are paying closer attention to equipment standards, not just how many systems connect to the grid.

Pair ALMM compliance with Kerala's updated KSERC rules (net metering caps, grid support charges above 10 kW, and emerging storage requirements for larger systems) and the message is clear: 2026 installations must be designed for compliance from day one, not retrofitted later.

Practical Takeaway

Ask your installer directly: "Which ALMM-listed panel model are you proposing, and is it DCR-compliant for PM Surya Ghar?" A reputable MNRE-approved partner will answer without hesitation. If they cannot, that is a red flag worth heeding before you pay a deposit.
