Solar Panel Price in India in 2026: Real Prices by Type & Brand

The Short Answer

Solar panels in India cost ₹18–₹45 per watt depending on type, brand, and technology. A standard 540W monocrystalline panel costs ₹13,000–₹19,000. For a complete 3kW residential system, panels alone account for ₹78,000–₹1,17,000 — roughly 40–50% of the total installed cost. Prices have dropped 25–30% over the past three years and continue to trend downward as manufacturing scales up.

Solar Panel Price by Type

Panel technology is the biggest price driver. Here are current market prices from our installer network:

Panel TypePrice per Watt540W Panel Price3kW System (panels only)
Polycrystalline₹18–₹24/W₹9,700–₹13,000₹58,000–₹78,000
Monocrystalline (PERC)₹24–₹32/W₹13,000–₹17,300₹78,000–₹1,04,000
Mono TOPCon₹28–₹36/W₹15,100–₹19,400₹91,000–₹1,17,000
Bifacial (Mono PERC)₹32–₹42/W₹17,300–₹22,700₹1,04,000–₹1,36,000
Bifacial (TOPCon)₹35–₹45/W₹18,900–₹24,300₹1,14,000–₹1,46,000

Prices based on quotes from verified installers. Actual prices vary by location and order volume.

Monocrystalline panels now dominate 80%+ of residential installations because their price premium over polycrystalline has narrowed while efficiency advantage has widened.

Solar Panel Price by Wattage

Higher-wattage panels cost more per unit but less per watt — and reduce installation costs by needing fewer panels, less wiring, and less mounting hardware.

Panel WattagePrice RangePanels for 3kWBest For
330–370W₹7,000–₹10,0008–9 panelsBudget systems, large roofs
400–450W₹10,000–₹14,0007 panelsMid-range residential
530–550W₹13,000–₹19,0006 panelsSpace-efficient, modern systems
580–600W₹17,000–₹24,0005 panelsPremium, limited roof space

The industry standard for new residential installations in 2026 is 530–550W panels. Older 330W panels are still available but less cost-effective when you factor in installation labour and mounting costs per panel.

Solar Panel Price by Brand

Brand pricing varies based on manufacturing scale, technology, and market positioning:

BrandOriginPrice/Watt (Mono)Tier
WaareeIndia₹24–₹30Tier 1
Tata Power SolarIndia₹27–₹33Tier 1
Adani SolarIndia₹22–₹28Tier 1
LuminousIndia₹24–₹30Tier 1
Vikram SolarIndia₹24–₹30Tier 1
Canadian SolarCanada/China₹28–₹35Global Tier 1
JA SolarChina₹25–₹32Global Tier 1
LONGiChina₹26–₹34Global Tier 1

Tier 1 status (Bloomberg NEF classification) indicates bankability and manufacturing scale — it does not guarantee the best product for every use case. Indian brands often offer better after-sales service and local warranty support.

What Determines Solar Panel Price?

Six factors drive the price you pay for solar panels:

  1. Cell technology — TOPCon and HJT cells cost more than PERC, which costs more than standard poly. Higher efficiency justifies the premium for space-constrained installations.
  2. Wattage and size — Higher-watt panels cost more per unit but less per watt. A 540W panel offers better value than two 270W panels.
  3. Brand and tier — Tier 1 brands charge a premium for better quality control, bankability, and warranty enforcement.
  4. BIS certification — Mandatory in India. Panels without BIS certification cannot be legally sold and do not qualify for government subsidies.
  5. Order volume — Bulk orders (10kW+ commercial) get 5–15% lower per-watt pricing. Residential orders (1–5kW) pay standard rates.
  6. Import vs domestic — India imposes a 40% basic customs duty (BCD) on imported solar cells and modules since April 2022, making domestic brands more price-competitive.

Panel Price vs Total System Cost

Solar panels are the largest single cost component, but they are only part of the total system price. Here is how the full cost breaks down for a typical 3kW on-grid system:

ComponentCost Range% of Total
Solar panels₹78,000–₹1,17,00040–50%
Inverter₹30,000–₹55,00018–25%
Mounting structure₹15,000–₹25,0008–12%
Wiring & electricals₹8,000–₹15,0005–8%
Installation labour₹10,000–₹20,0005–10%
Net metering & approvals₹5,000–₹12,0003–6%

Total 3kW system: ₹1,50,000–₹2,00,000 (before subsidy)

After PM Surya Ghar subsidy of ₹78,000, a 3kW system costs most homeowners ₹72,000–₹1,22,000 out of pocket.

Solar Panel Price Trends in India

Solar panel prices in India have followed a steep downward trajectory:

  • 2015: ₹55–₹70/W for polycrystalline
  • 2018: ₹28–₹40/W for mono PERC
  • 2022: ₹25–₹35/W for mono PERC (temporary spike due to polysilicon shortage)
  • 2024: ₹22–₹32/W for mono PERC, TOPCon entering market
  • 2026: ₹24–₹32/W for mono PERC, ₹28–₹36/W for TOPCon

The 40% BCD on imports (since April 2022) created a price floor for panels in India while simultaneously boosting domestic manufacturing capacity. India's domestic panel manufacturing capacity has grown from 8 GW in 2022 to over 60 GW in 2026.

Expect continued gradual declines as new gigawatt-scale factories from Adani, Reliance, Tata, and Waaree reach full production.

Common questions

What is the price of a 540W solar panel in India?
A 540W monocrystalline solar panel costs ₹13,000–₹19,000 in India depending on the brand and technology. Polycrystalline 540W panels cost ₹9,700–₹13,000. TOPCon technology panels of the same wattage cost ₹15,100–₹19,400. Prices include GST.
Why are solar panel prices different across brands?
Price differences reflect cell technology (PERC vs TOPCon vs HJT), manufacturing quality control, warranty terms, and brand positioning. Tier 1 brands charge more for better bankability and warranty enforcement. Domestic brands are often more affordable due to lower logistics costs and no import duty.
Are cheap solar panels worth buying?
Not recommended. Panels priced significantly below market rates often lack BIS certification, have shorter warranties, or use lower-grade cells that degrade faster. Since panels must last 25+ years, saving ₹2,000–₹3,000 per panel upfront can cost you lakhs in lost generation over the system lifetime.
How many solar panels do I need for a 3kW system?
With standard 540W panels, you need 6 panels for a 3kW system (6 × 540W = 3,240W). With 400W panels, you need 8. The number varies by panel wattage. Higher-wattage panels are more cost-effective because they reduce mounting and wiring costs.
Is there GST on solar panels in India?
Solar panels sold as part of a complete solar power system attract 13.8% GST under the composite supply rule. Panels bought separately attract 12% GST. Most installer quotes include GST in the total price. Always confirm whether a quote is inclusive of GST before comparing.
Will solar panel prices decrease further in India?
Gradual declines are expected as India's domestic manufacturing capacity scales up beyond 60 GW. However, the 40% import duty creates a price floor. Expect 5–10% annual reductions for equivalent technology, with most savings coming from newer, higher-efficiency panels at similar price points.
