Current solar panel installation costs in India: April 2026
The cost of a rooftop solar system in India depends on system size, panel technology, inverter type, and your city. The prices below are all-inclusive installation costs in North Indian cities: panels, inverter, mounting structure, wiring, installation labour, and DISCOM liaison included. These are not panel-only prices.
1 kW
Fully installed cost · Subsidy: up to Rs 30,000
Rs 45,000-60,000
2 kW
Fully installed cost · Subsidy: up to Rs 60,000
Rs 85,000-1,10,000
3 kW
Fully installed cost · Subsidy: up to Rs 78,000
Rs 1,20,000-1,50,000
5 kW
Fully installed cost · Subsidy capped at Rs 78,000
Rs 1,90,000-2,40,000
💡
After the Rs 78,000 PM Surya Ghar subsidy, a 3 kW system costs Rs 42,000 to Rs 72,000 net in most North Indian cities. At current electricity tariffs, this pays back in 4 to 6 years, then 20 more years of near-free electricity.

Why solar panel prices dropped 90% in 10 years
In 2014, installing 1 kW of rooftop solar in India cost approximately Rs 1,00,000. In April 2026 the same 1 kW costs Rs 45,000 to Rs 60,000 fully installed, and the panels themselves are significantly more efficient. This dramatic fall has multiple causes, and understanding them helps you know whether prices might fall further.
🏭 Chinese manufacturing scale China’s massive solar manufacturing expansion pushed global panel prices down by 80% between 2010 and 2024.
🔬 Technology improvements Mono PERC and TOPCon panels produce 20-30% more power per sq.m. than older polycrystalline panels at the same cost.
🏗️ India manufacturing scale Indian panel makers like Waaree, Adani and Vikram Solar have added significant capacity, reducing import dependency.
🔧 Inverter cost reduction Inverter prices have also fallen 70% since 2014. String inverters for 3-5 kW systems now cost Rs 12,000-25,000.
👷 Installer competition Growing installer market in tier 2 cities has driven installation labour costs down through competition.
📦 Component standardisation Mounting structures, cables and junction boxes have become commoditised, reducing per-system component costs significantly.
Solar panel price per watt: what you should expect to pay
A useful way to compare solar quotes is the cost per watt (or per kW) of installed capacity. This normalises quotes across different system sizes and makes comparison meaningful.
Panel Technology
Efficiency
Price Per Watt (Panel only)
Installed Cost Per kW
Polycrystalline (older tech)
16-18%
Rs 18-22 per watt
Rs 38,000-45,000
Mono PERC (current standard)
19-21%
Rs 22-28 per watt
Rs 42,000-52,000
TOPCon (premium)
21-23%
Rs 28-36 per watt
Rs 50,000-62,000
Bifacial Mono PERC
20-22% front + rear gain
Rs 25-32 per watt
Rs 48,000-58,000
These are panel-only prices. Add Rs 12,000-18,000 for inverter, Rs 6,000-10,000 for mounting structure, and Rs 8,000-15,000 for wiring, labour and DISCOM liaison to get the all-in installed price per kW. For brand-by-brand comparisons, see the best solar panel brands India 2026 guide.
Will solar prices fall further in 2026 and 2027?
The consensus view among solar industry analysts is that the major price falls are largely behind us. The cost curve is flattening. Prices may continue to fall 3 to 7 percent per year, but the dramatic 15-20 percent annual declines of 2017 to 2022 are not expected to repeat. There are a few factors that could push prices either way:
📉
Further China overcapacityIf Chinese manufacturers continue overproducing, global panel prices could fall another 10-15% by 2027.
🏭
India domestic manufacturingPLI scheme investments are adding Indian capacity, potentially reducing import costs further by 2026-27.
📈
Import duty riskIndia’s BCD on solar panels (40% on cells, 25% on modules) could rise, pushing prices up if policy changes.
💱
Rupee depreciationA weaker rupee increases import costs for components not yet manufactured in India at scale.
💡
Waiting for prices to fall further is a common reason people delay solar installation. The reality is that the subsidy (Rs 78,000) is a time-limited policy and not guaranteed to continue at current levels. The combination of today’s prices plus today’s subsidy is unlikely to get significantly better.

How to get accurate quotes and avoid overpricing
Use the price ranges above as a benchmark. If a quote is significantly above the range, ask the installer to justify the difference line by line. If it is significantly below, check whether corners are being cut on panel quality or ALMM compliance.
1
Get at least 3 quotes from DISCOM-empanelled installersAll quotes must be from the portal’s empanelled list. Non-empanelled installers cannot get you PM Surya Ghar subsidy regardless of how attractive their pricing is.
2
Ask for itemised breakdownEach quote should separate: panel cost, inverter cost, mounting structure, wiring, labour, and DISCOM/net metering process. Compare these line by line, not just the total.
3
Verify panel model and ALMM statusCheck the exact panel model quoted against the MNRE ALMM list at mnre.gov.in. A cheaper quote with non-ALMM panels costs you the entire subsidy.
4
Check warranty termsStandard warranties: 10-12 year product warranty and 25 year linear performance warranty on panels. 5 year on inverters. Ask for these in writing before confirming.
What is the cost of a 3 kW solar system in India in 2026?
A fully installed 3 kW rooftop solar system costs Rs 1,20,000 to Rs 1,50,000 in most North Indian cities in April 2026. After the PM Surya Ghar subsidy of up to Rs 78,000, the net cost is Rs 42,000 to Rs 72,000. Prices vary by city, panel technology chosen, and installer.
Why did solar panel prices in India fall so much?
The primary driver is China’s massive manufacturing scale, which pushed global panel prices down by over 80 percent between 2010 and 2024. Technology improvements increased panel efficiency while manufacturing costs fell. Growing Indian manufacturing capacity, competition among installers, and commoditisation of components all contributed further.
Should I wait for prices to fall further before installing solar?
The major price falls are largely behind us. Prices may fall 3 to 7 percent annually, but the PM Surya Ghar subsidy of Rs 78,000 is not guaranteed to continue indefinitely. The combination of current prices plus current subsidy represents a strong value case. Waiting risks missing the subsidy window without a corresponding price benefit.
What is the cost per kW for solar installation in India?
The all-inclusive installed cost per kW in North India ranges from Rs 42,000 to Rs 62,000 depending on panel technology, from standard Mono PERC at the lower end to premium TOPCon panels at the higher end. Panel-only cost is Rs 22 to Rs 36 per watt depending on technology.
Are cheaper solar quotes always a bad sign?
Not always, but they require scrutiny. A quote significantly below market may use non-ALMM panels (which disqualify you for subsidy), undersize the inverter, skip proper earthing, or exclude DISCOM liaison. Ask for an itemised breakdown and verify every major component before accepting any quote significantly below the ranges above.
