If you’ve been tracking solar panel prices in India over the last few months, you’ve probably noticed something odd: quotes that felt settled in April suddenly look different in July. You’re not imagining it, and you’re not being overcharged. Something genuinely changed on the policy side, and it’s worth fifteen minutes to understand before you sign a contract for your rooftop system.
Most homeowners assume solar prices only move because of raw material costs or exchange rates. This time, the trigger is regulatory, and it’s specific enough that a quick explanation will help you read any quote you get from here on with a lot more confidence.
What Actually Changed on June 1, 2026
The short version: India’s Ministry of New and Renewable Energy (MNRE) made it compulsory for solar cells, not just the finished panels, to be sourced from approved domestic manufacturers. This is called ALMM List-II, and it came into force on June 1, 2026.
Until now, a panel could carry an “ALMM List-I” approval even if the raw solar cells inside it were imported, mostly from China. From June 2026 onward, that loophole is closed. Manufacturers must prove their cells come from a domestic, government-approved supplier list, or the panel model risks losing its List-I approval altogether. This matters because only List-I approved panels are eligible for government schemes, net-metering projects, and subsidy-linked residential installs.
| What Changed | Before June 2026 | After June 2026 |
| Panel approval | Module (ALMM List-I) only | Module + Cell (List-I + List-II) |
| Cell sourcing | Imported cells allowed | Must be domestic, List-II approved |
| Subsidy eligibility | Tied to List-I module | Tied to both lists together |
| Non-compliant panels | Still usable | Risk being delisted from List-I |
| Net-metering & open access | Module compliance only | Module + cell compliance required |
There’s also a grandfathering clause worth knowing about. Projects where the bid or booking was finalised before a set cut-off date are exempt from the cell requirement, even if the actual installation happens after June 2026. For most retail homeowners booking fresh installations now, though, this exemption doesn’t apply; new bookings fall under the full List-I plus List-II requirement.
Why This Is Pushing Solar Panel Prices Up
This isn’t a random price hike, it’s supply and demand doing exactly what you’d expect. India’s panel manufacturing capacity is enormous, but domestic cell manufacturing hasn’t caught up at the same pace. Industry estimates put approved domestic cell capacity at around 30 GW, against panel manufacturing capacity closer to 190-200 GW. That gap means fewer manufacturers can currently produce fully compliant panels, and the ones who can are commanding a premium while the market adjusts.
Here’s what’s actually driving the increase, broken down:
- Cell shortage, not panel shortage. Panels themselves aren’t hard to find. Compliant cells inside those panels are the bottleneck.
- Certification backlog. Testing and approval for new cell manufacturers takes months, which is slowing how fast new compliant capacity comes online. Industry sources are forecasting certification delays of six to nine months in some cases.
- Cost pass-through. Domestically sourced cells currently cost more per watt than the imported cells they’re replacing roughly ₹8 to ₹10 more per watt by some estimates and that difference lands on the final invoice.
- Panic buying before the deadline. A lot of installers rushed to procure and commission systems before June 1 using older stock, which temporarily tightened the supply of freshly compliant panels right after the deadline passed.
- Technology-specific gaps. The mismatch is sharper for certain panel technologies. TOPCon panels, which have become popular for their efficiency, have a much bigger gap between approved module capacity and actual domestic cell capacity than older panel types.
None of this means solar has become a bad investment. It means the market is going through a supply-side adjustment that’s expected to smooth out as domestic cell factories scale up over the coming months.

How Much Have Prices Actually Moved?
For homeowners, the shift is real but not dramatic. Think of it as a moderate bump rather than a shock. Most residential installers are currently quoting all-inclusive rooftop system costs somewhere in the ₹55-₹85 per watt range, depending on system size, panel technology, and your city. A typical 3 kW home system before subsidy now falls roughly between ₹1.6 lakh and ₹2.4 lakh, compared to slightly lower figures earlier in the year.
| System Size | Approx. Cost Before Subsidy | After PM Surya Ghar Subsidy |
| 1 kW | ₹70,000 – ₹90,000 | ₹40,000 – ₹60,000 |
| 2 kW | ₹1.3 – ₹1.6 lakh | ₹70,000 – ₹1 lakh |
| 3 kW | ₹1.9 – ₹2.4 lakh | ₹1.1 – ₹1.6 lakh |
| 5 kW | ₹3 – ₹3.6 lakh | Subsidy capped at 3 kW slab |
Figures are indicative and vary by installer, panel technology, and location always get a site-specific quote before finalising.
A useful way to think about it: the panel itself is usually not where most of the cost sits. Inverter quality, mounting structure, wiring, net-metering paperwork, and installation labour make up a large share of the bill too. So even with cell-driven panel price increases, your total system cost doesn’t move by the same percentage as raw cell prices do.
Does This Affect Your PM Surya Ghar Subsidy?
Good news here: the central subsidy structure itself hasn’t changed. You can still claim up to ₹78,000 for residential systems under the PM Surya Ghar Muft Bijli Yojana, based on your system’s kW capacity. What’s changed is which panels qualify. Your installer now needs to confirm the exact panel model is compliant with both ALMM List-I and List-II before installation, or your subsidy claim could run into trouble at the DISCOM verification stage.
A quick way to protect yourself before you sign anything:
- Ask your installer for the exact panel model name and its current ALMM List-I status.
- Confirm the cell manufacturer used in that panel is separately listed under ALMM List-II.
- Get this confirmation in writing, not just a verbal assurance.
- Be cautious of installers offering older stock that was approved before June 2026 but hasn’t been re-verified against the new cell requirement.
- Cross-check the panel model against the official MNRE ALMM list before signing your final agreement.
What This Means If You’re Installing in Tamil Nadu or Kerala
South India has been one of the fastest-growing rooftop solar markets in the country, and this rule doesn’t change that underlying momentum, it just changes the paperwork your installer needs to get right. State-level net-metering approvals in Tamil Nadu and Kerala already require ALMM-listed modules, so the addition of cell-level compliance is really an extension of a process installers here are already familiar with.
If you’re comparing quotes right now, the panel price alone won’t tell you much. Two installers quoting similar per-watt rates could be offering very different compliance guarantees, and that difference only becomes visible when your subsidy application gets reviewed. The safer approach is to ask direct questions about cell sourcing rather than comparing bottom-line numbers alone.
Should You Wait or Install Now?
This is the question most homeowners are actually asking, so here’s a direct answer: waiting is unlikely to save you money. Domestic cell capacity is expanding steadily, and once supply catches up, prices are expected to stabilize rather than fall back sharply the underlying manufacturing cost of compliant cells isn’t going away. Meanwhile, every month you delay is a month of electricity bills you’re still paying in full, plus a narrower window before your local DISCOM’s subsidy quota or state-level scheme allocation tightens further.
If your roof and budget are ready, installing now with a verified, compliant panel locks in your subsidy and your savings timeline without betting on a price drop that current industry estimates don’t strongly support. The bigger risk isn’t a slightly higher panel price today, it’s installing non-compliant panels and losing your subsidy eligibility later.
What to Ask Before You Sign a Quote
A well-informed homeowner is the best protection against both overpaying and losing subsidy eligibility. Before finalising any installer, it helps to ask a few pointed questions rather than relying on a single price comparison sheet. Ask exactly which panel brand and model is being proposed, and request the ALMM List-I and List-II reference numbers in writing. Ask whether the quoted price is locked for a fixed period, since cell prices are still moving. And ask what happens if the specific panel model gets delisted before your installation date. A reliable installer should have a clear answer, not a vague reassurance.
The Bottom Line
The solar panel price in India hasn’t shifted because solar suddenly became a worse investment, it’s shifted because the government tightened where the components inside your panel are allowed to come from. For homeowners, the smart move isn’t to panic or pause. It’s to work with an installer who can clearly show you compliant, ALMM List-II verified panels, so your subsidy stays protected and your system keeps delivering the same 20-plus years of savings solar has always promised.

FAQs
-
Will solar prices keep rising after 2026?
Short-term pressure is expected to ease as domestic cell capacity scales up over the next 12-18 months, but a return to older, lower prices isn’t guaranteed.
-
Does ALMM List-II apply to home rooftop systems?
Yes, subsidy-linked residential systems fall under this requirement, so your installer’s panel choice directly affects your PM Surya Ghar claim.
-
Can I still get panels that aren’t ALMM List-II compliant?
You may find them in the market, but they carry real risk to your subsidy eligibility and long-term warranty support it’s not worth the shortcut.
-
Is the ₹78,000 subsidy cap still valid?
Yes, the subsidy amounts under PM Surya Ghar haven’t changed only the compliance requirements for eligible panels have.
-
Will panel prices come back down soon?
Gradually, as more domestic cell manufacturers get listed and certified, supply pressure should ease, but a sharp near-term drop isn’t the current industry expectation.
