PM Surya Ghar Muft Bijli Yojana 2026: Subsidy Slabs, Eligibility and the ALMM Compliance Trap

There's a version of the PM Surya Ghar story that everyone already knows: the Prime Minister announced it in February 2024, the Cabinet signed off two weeks later, and the pitch was irresistible — solarise your roof, get up to ₹78,000 back from the government, and watch your electricity bill approach zero. Ten million households, thirty gigawatts, one of the most ambitious residential energy programmes any government has ever attempted.

That's the headline. But if you actually sit with the scheme's 2026 numbers, a more interesting — and more complicated — story starts to surface. It's a story about a government subsidy standing still while the raw materials underneath it move, and about a compliance rule that quietly rewired where India's solar panels get their cells from.

 The subsidy math is simpler than it looks — and that's the problem

 The structure itself is almost elegant. Thirty thousand rupees for your first kilowatt, another thirty thousand for your second, eighteen thousand for your third — and then nothing. Install a 3kW system and you get the full ₹78,000. Install a 5kW system because you actually want to run your air conditioner off solar, and you still get ₹78,000. The extra two kilowatts of panels, mounting hardware and wiring comes entirely out of your own pocket, or gets folded into the collateral-free loan the scheme's public-sector banking partners offer.

 That flat cap was fine in 2024. It's a different proposition in 2026, for one specific reason: the subsidy isn't calculated against what you are actually charged by the installer. However, it's calculated against MNRE's own fixed benchmark cost for your region. If the quote comes in above that benchmark, which is likely to be then you eat the difference. The subsidy doesn't stretch. It just becomes a smaller and smaller slice of the total bill.

 The loophole nobody was watching — until June 2026

 Here's the important part of the scheme that barely makes headlines but genuinely determines whether your subsidy shows up: ALMM, the Approved List of Models and Manufacturers.

For years, "ALMM-compliant" effectively meant one thing — your panel had to be assembled in India, on a list called List-I. What it didn't mean was that the cells inside the panel were indigeneous. A manufacturer could import cells from China, snap them into a frame on Indian soil, and still qualify. It was domestic assembly wearing the costume of domestic manufacturing.

That loophole closed on 1 June 2026. From that date, any List-I panel also has to use cells sourced from a domestically approved cell manufacturer — List-II. MNRE did carve out a narrow exemption, extended in July to run through 31 December 2026, but it only covers net-metering and open-access projects — which, conveniently, is most of what PM Surya Ghar actually is. After 1 January 2027, though, there's no more grace period. Full compliance, no exceptions.

 Why does this matter for an ordinary homeowner? Because ALMM listing isn't granted to a brand — it's granted to a specific model number. Your installer's brochure can proudly display a well-known manufacturer's name, and the exact model they're quoting you can still fall outside the list. The only real protection is checking the model number yourself against MNRE's portal before you sign anything. Across the industry, non-ALMM equipment is now, by a wide margin, the single biggest reason subsidy claims get rejected — usually discovered only after the panels are already bolted to your roof.

 Where the real cost pressure is coming from

Now for the part of this story that almost nobody connects back to a home solar subsidy: metal prices.

Every rooftop installation, no matter how efficient the panel, needs a skeleton and a nervous system. The skeleton is aluminium — or sometimes galvanized steel — bent into the mounting rails and brackets that hold the panels to your roof. The nervous system is copper, running through every wire, every earthing connection, every link between panel and inverter and grid.

Neither of these is subsidised. They sit entirely outside MNRE's benchmark calculation, and 2026 has not been kind to either of them. Aluminium climbed roughly 28% year-on-year, touching $3,362 a tonne by early September, pushed up by everything from Gulf supply disruptions tied to US-Iran tensions to LME inventories sitting at a 36-year low. Copper, meanwhile, has been trading above $11,400 a tonne on a more structural problem — global ore grades are quietly declining every year, forcing miners to dig through more rock for the same output, while major mines in Indonesia and the Congo have suffered serious operational disruptions.

None of that shows up in a government press release about PM Surya Ghar. But it shows up in your installer's quote. A ₹78,000 subsidy that once covered close to 40% of a system's cost now covers noticeably less, and the gap doesn't disappear — it either lands on the consumer, gets pushed onto the loan facility, or gets squeezed out of the installer's own margin.

 The part that's actually working

It would be unfair to leave the story there, because the manufacturing side of this has genuinely delivered. India's module capacity has exploded from around 120GW in mid-2025 to over 230GW by early 2026 — a scale-up that would have seemed implausible a few years ago. The Production Linked Incentive scheme has pulled in serious industrial names — Reliance, Adani, Tata Power, Waaree — and pushed the country toward more advanced cell technologies like TOPCon and heterojunction cells, some exceeding 25% efficiency.

The honest caveat is that this growth is lopsided. Module assembly capacity has raced ahead while the upstream layers — cells, wafers, polysilicon — have lagged far behind, which is exactly why the List-II crackdown happened in the first place. MNRE is trying to force the same domestic-content discipline upstream that it already achieved at the assembly stage. It's a sensible policy instinct. It's also precisely the kind of tightening that catches installers and homeowners off guard if nobody told them the rules changed in June.

 So where does that leave a household actually thinking about applying?

Probably still worth doing — the payback period on a well-sized 3kW system, after subsidy, still lands around two to three years in most parts of the country, and 25-year savings can run into the lakhs. But it's worth walking in with your eyes open on a few fronts: verify the exact model number of your panel against MNRE's ALMM registry yourself, don't take a brand name at face value, get your Aadhaar-bank linkage sorted early since it's the single most common reason DBT payments fail, and don't be surprised if your quote sits above whatever number you saw quoted online a year ago — that's not necessarily your installer padding margins, it's aluminium and copper doing what commodity markets do.

The subsidy hasn't shrunk on paper. It's just buying a little less roof than it used to.
