Solar Panel Price Trends 2026

Every solar EPC principal in Surat or Pune has the same question sitting on their desk right now: should we lock in module prices today, or wait another quarter? Prices have been falling faster than most industry forecasts predicted, yet not every buyer is capturing those savings, because the India-specific dynamics of ALMM lists, DCR premiums, and the Chinese manufacturing glut work differently from what you read in global reports. This post breaks down exactly what is happening to panel prices, why, and what to expect in the second half of 2026.

What The Module Cost Curve means for Indian buyers

The Module Cost Curve is a three-force framework that explains why Indian solar panel prices do not simply mirror the global spot market:

1. Chinese manufacturing glut, China added 160 GW of new cell and module capacity in 2024–25 (BNEF, 2025), creating an oversupply that pushed global mono-PERC prices to below $0.09/Wp by Q1 2026.
2. ALMM DCR effect, India's Approved List of Models and Manufacturers (ALMM) under MNRE restricts government-funded projects to listed modules, and the Basic Customs Duty of 40% on imported cells/modules means that Chinese modules cannot freely enter India at spot prices. This creates a price floor.
3. Indian manufacturing ramp, Domestic cell capacity from Adani, Waaree, Vikram, and new entrants is scaling rapidly; as it does, the DCR premium compresses, and ALMM-listed domestic prices converge slowly toward global levels.

The interaction of these three forces means your procurement decision is never just about global trends, it is about where you sit relative to the ALMM list and whether your project is under a government scheme or a private rooftop sale.

Why Chinese oversupply matters even when you cannot import freely

You might wonder why you should care about Chinese spot prices if the customs duty wall prevents direct import. There are three indirect transmission mechanisms:

Competitive pressure on domestic manufacturers. Indian module makers know that the duty protects them but does not protect them forever, policy can change. They are aggressively investing in scale to bring their costs below the duty-adjusted Chinese price. Waaree, for instance, commissioned 5 GW of new module capacity in FY 2025 (Business Standard, 2025). As domestic output grows, inter-manufacturer competition pushes prices down.

Non-ALMM segment pricing. For private rooftop projects, the bulk of residential solar under PM Surya Ghar Yojana, the ALMM restriction does not always apply at the same strictness. Some state DISCOMs accept non-ALMM modules for private rooftop net metering. In those segments, grey-channel pricing is 10–15% lower, which creates price discovery pressure on official channels.

BOS cost use. Even if you cannot negotiate modules down further, the global oversupply has softened inverter, mounting structure, and cable prices. The full system cost matters more than any single line item. We look at this in the next section.

How ALMM sets the Indian price floor

The MNRE's ALMM (Approved List of Models and Manufacturers) was introduced to ensure quality and support domestic manufacturing. For any project receiving central financial assistance, including PM Surya Ghar subsidies, only ALMM-listed modules are eligible. The ALMM glossary page explains the listing process in detail.

The practical effect is a two-tier Indian market:

• ALMM-mandatory segment: Government rooftop schemes, PSU projects, state government tenders. Must use listed modules. Price floor around ₹24–26/Wp for mono-PERC in H1 2026.
• Non-ALMM segment: Private commercial/industrial rooftop, off-grid, and some state net metering projects where local DISCOM does not enforce ALMM. Prices as low as ₹21–23/Wp for non-listed modules.

The gap between these tiers has been narrowing. In 2023, it was ₹5–7/Wp. By mid-2026 it is ₹2–4/Wp. As Indian manufacturers scale, the ALMM price floor itself drifts down.

The DCR premium: what you are actually paying for

The Domestic Content Requirement (DCR) premium is the difference in price between ALMM-listed Indian modules and what equivalent-wattage modules would cost if freely imported. In mid-2026, this premium is approximately ₹4–6/Wp.

For a 3 kWp residential system, that means the customer is paying ₹12,000–18,000 more in module costs than if they could buy global market modules. But this needs context:

• The PM Surya Ghar subsidy, ₹30,000 for a 1 kW system, up to ₹78,000 for 3 kW+, more than compensates for the DCR premium on residential installations. Learn more in our PM Surya Ghar subsidy slabs guide.
• Commercial projects without subsidy do carry the full DCR burden. This is the segment where procurement timing matters most.

Indian manufacturing capacity ramp and what it means for prices

Domestic panel manufacturing is the single biggest structural force that will bring Indian module prices down in the medium term. The key developments in 2025–26:

Adani Green Energy expanded its integrated cell-to-module line to 4 GW annual capacity. Waaree Energies added 5 GW. Vikram Solar commissioned its 3.5 GW module facility. Premier Energies and Goldi Solar also expanded aggressively (Mercom India, 2025).

The total domestic module capacity in India crossed 50 GW by end-2025, against an annual domestic demand of approximately 25 GW (MNRE annual report, 2025). This means India is approaching manufacturing self-sufficiency at scale, which structurally reduces the ALMM premium over the next 24–36 months.

TOPCon vs PERC: which technology wins on price per kWh generated

The technology shift from PERC to TOPCon (Tunnel Oxide Passivated Contact) is accelerating. TOPCon modules have a higher per-Wp cost but generate 3–5% more energy from the same roof area due to higher efficiency and better low-light performance.

For Indian installers, the decision matrix is:

• Space-constrained rooftop (residential): TOPCon wins on total yield despite higher per-Wp cost, especially in Western India where irradiance is high.
• Open ground-mount or large commercial: Bifacial PERC remains more cost-efficient because space is not a constraint and bifacial gain adds 8–12% extra energy.
• PM Surya Ghar subsidy projects: PERC still dominates because the subsidy structure is per kW installed, not per unit generated. Using the cheapest ALMM-listed module maximises the subsidy-to-cost ratio.

What to expect in H2 2026 and beyond

Based on the three forces in The Module Cost Curve, here is the likely trajectory for Indian solar panel prices through end-2027:

H2 2026: ALMM mono-PERC prices likely hold at ₹23–25/Wp as domestic manufacturers protect margins. Some downward pressure from new capacity coming online. Inverter prices, especially string inverters from Sungrow and Delta, likely fall 5–8% as Chinese exports increase. Total system cost for a 3 kWp residential installation likely dips below ₹1.5 lakh (before subsidy) by Q4 2026.

2027: As Indian manufacturing hits 60+ GW capacity against ~30 GW domestic demand, inter-brand competition will accelerate. ALMM mono-PERC prices could reach ₹20–22/Wp. The DCR premium shrinks. This is when the global glut's pressure genuinely transmits into Indian prices.

Medium-term risk: Any reversal of Basic Customs Duty policy or new trade restrictions could reset the trajectory. Watch MNRE policy announcements quarterly.

Pros and cons of falling module prices for EPCs

How to protect your margin in a falling-price market

1. 1
   Quote validity windows of 7–14 days only. With prices moving monthly, a 30-day quote expiry is a liability. Use a CRM like QuickEstimate to set auto-expiry reminders and re-quote easily without starting from scratch.
2. 2
   Carry 30–45 days of module inventory, not 90. In a falling market, overstocking at today's prices and selling at tomorrow's prices erodes margin. Tighter inventory cycles require faster sales velocity, which is where [pipeline management](/features/pipeline-management) tools earn their keep.
3. 3
   Bundle installation labour and AMC into your proposal. Services do not deflate with module prices. If you build out an annual maintenance contract component, your total revenue per customer is protected even as hardware margins compress.
4. 4
   Use price-fall as a lead-generation trigger. A "prices have dropped again" WhatsApp broadcast to your past-inquiry list converts cold leads at very low cost. This is easier to do consistently when you have a [lead capture](/features/lead-capture) system tracking every inquiry.

How QuickEstimate fits

• Proposal Generator, When module prices change, you need to update your pricing in one place and have every new proposal reflect the current cost. QuickEstimate's proposal generator lets you do this in under two minutes, no chasing spreadsheet copies on your team's phones.
• Quotation System, Set quote validity periods and get notified when a quote is about to expire. In a falling-price market, expired quotes that get re-opened at the old price can create customer disputes. Auto-expiry prevents this.
• WhatsApp Follow-up, Use price-drop events as follow-up triggers. When module prices fall, send a personalised "good news on pricing" message to every lead who did not convert last month. Read receipts tell you who is interested.
• Sales Reports, Track whether your margin per kWp is holding as module prices change. If it is eroding, you will see it in the data before it becomes a cash flow problem.

What to do this week

1. Audit your current module procurement price against the benchmarks in this post. If you are paying above ₹27/Wp for standard mono-PERC from a domestic supplier, you have room to negotiate, especially if you can commit to a 50–100 panel minimum order.
2. Check your open quotations. Any quote older than 30 days should be reviewed. If module prices have dropped since you quoted, consider proactively updating the customer's price, the goodwill is worth more than the margin you would have captured.
3. Build a "prices have fallen" lead reactivation campaign. Pull every lead from the last 6 months who did not convert and send them an updated ROI calculation via WhatsApp. Use QuickEstimate's follow-up tool to send and track responses in one place.

Frequently asked questions

Why are solar panel prices falling in India in 2026?

Prices are falling due to a combination of Chinese manufacturing overcapacity pushing global spot prices to decade lows, increasing domestic Indian manufacturing scale reducing costs, and greater competition between ALMM-listed suppliers. The full mechanism is explained by The Module Cost Curve framework in this article.

What is the price of a solar panel in India in 2026?

ALMM-listed mono-PERC modules are priced at approximately ₹24–26 per Wp as of mid-2026. Non-ALMM modules in the grey channel are available at ₹18–21/Wp but cannot be used for PM Surya Ghar or government-funded projects.

What is the ALMM list and why does it affect solar panel prices in India?

The ALMM (Approved List of Models and Manufacturers) maintained by MNRE lists modules eligible for use in government-funded solar projects. Because the 40% Basic Customs Duty blocks cheap imports, only domestic or duty-adjusted imported modules reach ALMM. This creates a price floor of roughly ₹23–26/Wp for ALMM-listed mono-PERC in 2026.

Will solar panel prices keep falling in 2027?

Based on the trajectory of Indian manufacturing capacity expansion, heading toward 60+ GW by end-2027 against ~30 GW annual demand, yes. ALMM mono-PERC prices are likely to reach ₹20–22/Wp by end-2027, assuming no major duty policy change.

What is the DCR premium and how much does it cost a buyer?

The Domestic Content Requirement (DCR) premium is the price difference between ALMM-listed domestic modules and equivalent global market modules. As of mid-2026, it is approximately ₹4–6/Wp, or ₹12,000–18,000 for a 3 kWp system. For PM Surya Ghar subsidy projects, the subsidy far exceeds this premium.

Should I buy TOPCon or PERC modules for residential installations in 2026?

For PM Surya Ghar subsidy projects, PERC bifacial is the better financial choice because the subsidy structure rewards per-kW cost efficiency. For premium space-constrained rooftops without subsidy, TOPCon's higher efficiency justifies the ₹5–10/Wp premium.

Are there any hidden costs beyond the module price in a solar installation?

Yes. Module price is one of seven major cost lines. The others are inverter, balance-of-system (BOS), mounting structure, wiring, installation labour, and commissioning/paperwork. Our complete cost breakdown guide covers every line item with current 2026 rates.

How does GST affect solar panel prices in India?

Solar panels attract 12% GST since the 2022 revision (up from 5%). This adds approximately ₹3–4 to the effective per-Wp cost for the end customer. Installation services attract 18% GST. Understanding the GST structure is essential when building quotations.
