Let me ask you something.
If you were thinking about going solar back in 2022, someone probably told you – “Wait, prices will come down.” And they were right. Prices did fall.
But here’s what nobody tells you in 2026: that wait may now cost you more, not less.
Solar panel prices in India have followed a dramatic curve over the last three years. Understanding this trend helps you make a smarter buying decision, whether you’re planning solar panel installation cost for homes in India or scaling up for commercial use.
Let’s break it down year by year with real numbers.
Where Solar Prices Stood in 2024
In 2024, India’s solar market was in a full price-drop cycle.
- Average panel price per watt: ₹70 – ₹80/watt
- 1 kW rooftop system: ₹1,10,000 – ₹1,30,000
- 3 kW system: ₹2,30,000 – ₹2,60,000
- 5 kW system: ₹3,50,000 – ₹3,90,000
The main driver?
Cheap Chinese imports flooding the global market, keeping raw material costs low. GST on solar modules was still at 12%, which added to overall costs. Despite the relatively higher panel prices, demand was rising because subsidy awareness was improving after PM Surya Ghar launched in early 2024.
The sentiment in 2024 was: solar is getting affordable, but not cheap enough yet for the average Indian homeowner to act without hesitation.
What Changed in 2025
2025 was a turning point in more ways than one.
The government reduced GST on solar PV modules and related equipment from 12% to 5%, which directly reduced project costs for both residential and commercial buyers. This was one of the biggest policy-driven price corrections in recent years.
2025 price range:
- Per watt (panel only): ₹32 – ₹55/watt
- 1 kW complete system: ₹75,000 – ₹1,00,000
- 3 kW system: ₹2,00,000 – ₹2,40,000
- 5 kW system: ₹2,80,000 – ₹3,50,000
The PM Surya Ghar subsidy scheme gained major momentum and over 10 lakh applications were processed. Solar panel installation cost for homes in India became genuinely accessible to middle-income households, especially in states like Tamil Nadu, Rajasthan, and Gujarat.
For most homeowners, 2025 was the first time rooftop solar felt like a realistic 3-year payback investment rather than a luxury decision.
Solar Panel Price in 2026 – The New Reality
Here is where things get interesting – and slightly uncomfortable.
The cheap solar era is over.
A structural shift driven by global commodity inflation, China’s revised export policies, and India’s enforcement of ALMM (Approved List of Models and Manufacturers) regulations has pushed solar project costs up by approximately 25% compared to 2025 for commercial and industrial buyers.
For residential buyers, the picture is slightly different because PM Surya Ghar subsidies buffer the impact.
2026 price range (residential):
| System Size | Cost Before Subsidy | PM Surya Ghar Subsidy | Effective Cost |
| 1 kW | ₹65,000 – ₹80,000 | ₹30,000 | ₹35,000 – ₹50,000 |
| 2 kW | ₹1,20,000 – ₹1,50,000 | ₹60,000 | ₹60,000 – ₹90,000 |
| 3 kW | ₹1,70,000 – ₹2,10,000 | ₹78,000 | ₹92,000 – ₹1,32,000 |
| 5 kW | ₹2,80,000 – ₹3,50,000 | ₹78,000 | ₹2,02,000 – ₹2,72,000 |

5kW Solar Panel Price with Subsidy in India
Per watt cost in 2026 by panel type:
| Panel Type | Price Per Watt |
| Polycrystalline | ₹22 – ₹26 |
| Monocrystalline | ₹26 – ₹32 |
| Bifacial | ₹32 – ₹40 |
The panel-only price looks low but the complete installed cost per watt (including inverter, mounting, wiring, and labour) sits at ₹55 – ₹85/watt for residential on-grid systems in 2026.
Year-on-Year Price Comparison at a Glance
| Year | Per Watt (Panel) | 3 kW System Cost | Key Driver |
| 2024 | ₹70 – ₹80 | ₹2,30,000 – ₹2,60,000 | Chinese imports, high GST |
| 2025 | ₹32 – ₹55 | ₹2,00,000 – ₹2,40,000 | GST cut to 5%, subsidy push |
| 2026 | ₹22 – ₹45 | ₹1,70,000 – ₹2,10,000* | ALMM enforcement, commodity inflation |
*Before subsidy. After PM Surya Ghar subsidy, effective cost drops to ₹92,000 – ₹1,32,000.
Panel-only prices look like they dropped in 2026 and they did for certain module types. But total installed cost has stabilised or slightly increased due to inverter prices, balance-of-system components, and labour costs rising.
What Drives Solar Panel Pricing in India
Understanding the price isn’t just about the panel. Here are the real factors behind solar pricing in India:
- Panel type – Monocrystalline costs more but gives better output in limited roof space
- Inverter quality – String inverters vs microinverters make a ₹15,000–₹40,000 difference
- Brand – Tata Solar (₹28–₹34/watt), Waaree (₹25–₹30/watt), Vikram Solar (₹24–₹29/watt)
- State policies – Tamil Nadu, Karnataka, and Gujarat have additional state subsidies on top of central
- DISCOM charges – Net metering fees and grid connection costs vary by state
- Roof type – RCC roof vs metal shed affects mounting cost by ₹8,000–₹20,000
Is 2026 Still a Good Time to Buy Solar?
Yes, and here is why.
Even with prices stabilising, the subsidy window under PM Surya Ghar is still open. A 3 kW system after subsidy costs around ₹1,00,000 – ₹1,32,000, with a payback period of 3 to 3.5 years and lifetime savings of ₹7–9 lakh over 25 years.
If you’re considering buying rooftop solar panels in 2026, the math still works strongly in your favour especially in South India where electricity tariffs from DISCOMs like TANGEDCO, BESCOM, and APSPDCL have been rising every year.
The risk of waiting?
ALMM enforcement is expected to tighten further in the second half of 2026, which could push complete system costs up by another 10–15%.

Final Word
Solar pricing in India went through three distinct phases:
- 2024 – Relatively high, imports dominant, subsidy just launched
- 2025 – Sweet spot, GST cut, cheapest complete system costs
- 2026 – Panel prices stable, installed costs creeping up, subsidy still available
If you’re researching solar panel installation cost for homes in India or comparing solar pricing in India across brands, the data is clear: act in 2026 while subsidies are intact, before the next policy shift changes the numbers.

FAQs
1. What is the cost of 3kW solar panel?
A 3 kW solar system costs ₹1,70,000 – ₹2,10,000 before subsidy. After PM Surya Ghar central subsidy of ₹78,000, the effective cost comes down to ₹92,000 – ₹1,32,000.
2. What is the price of 1 kW solar panel?
A 1 kW solar system in India costs ₹65,000 – ₹80,000. With PM Surya Ghar subsidy of ₹30,000, you pay only ₹35,000 – ₹50,000 after subsidy.
3. Which solar is best for a home?
A grid-connected (on-grid) monocrystalline solar system is best for homes, it gives higher efficiency, qualifies for net metering, and is eligible for PM Surya Ghar subsidy. A 2–3 kW system suits most Indian households.
4. How much for 1 panel solar?
A single solar panel (400W–550W) costs ₹10,000 – ₹18,000 depending on the brand and type. Monocrystalline panels from brands like Tata, Waaree, or Adani fall in the ₹12,000 – ₹16,000 range per panel.
5. How many AC can run in 1 kW solar system?
A 1 kW solar system cannot run an AC independently – it generates only 90–110 units/month. You need a minimum 3–5 kW system to comfortably run a 1-ton AC along with other home appliances.
