Solar panel price in India 2026: 1kW, 3kW, 5kW and 10kW breakdown
One of the first questions anyone researching solar asks is: how much does it actually cost? The answer depends on your system size, panel brand, inverter type, and location. This guide breaks down current solar panel prices in India for 2026, explains what you are actually paying for, and shows you how to judge whether a quote you receive is reasonable.
What does a complete solar system include?
When an installer quotes you a price, a complete rooftop solar system includes four main components.
Solar panels are the most visible part and generate electricity from sunlight. Panel prices vary by technology type, brand, and wattage rating.
Solar inverter converts the DC electricity from panels into AC electricity used by your home appliances. The inverter is critical to system performance and longevity.
Balance of system includes mounting structure (the frame that holds panels on your roof), AC and DC cables, junction boxes, earthing, and safety switches. This is often underestimated in cost discussions.
Installation and civil work covers labour, any minor roof strengthening, cable routing, and commissioning. In metro cities, labour costs are higher than in smaller towns.
A quote that seems low may be cutting corners on inverter quality or balance of system components. Always ask for a breakdown.
Solar panel prices in India 2026: by system size
These are indicative fully installed system prices including panels, inverter, mounting, wiring, and installation. Prices vary by city, brand, and installer.
| System size | Price range (before subsidy) | After PM Surya Ghar subsidy |
|---|---|---|
| 1 kW | Rs 60,000 to Rs 85,000 | Rs 30,000 to Rs 55,000 |
| 2 kW | Rs 1.1 lakh to Rs 1.5 lakh | Rs 50,000 to Rs 90,000 |
| 3 kW | Rs 1.5 lakh to Rs 2 lakh | Rs 75,000 to Rs 1.25 lakh |
| 5 kW | Rs 2.3 lakh to Rs 3.2 lakh | Rs 1.55 lakh to Rs 2.45 lakh |
| 10 kW | Rs 4.5 lakh to Rs 6 lakh | Rs 3.75 lakh to Rs 5.25 lakh |
Note: Prices above are indicative for 2026 and can vary by 15 to 25 percent depending on location, brand choice, and market conditions. Always get multiple quotes before deciding.
What affects the price of a solar system?
Panel technology
Polycrystalline panels are the most affordable, with lower efficiency (16 to 17 percent) and a longer payback period. They are less common in new installations but still used in cost-sensitive projects.
Monocrystalline PERC panels are the current standard in India, with efficiency of 19 to 21 percent. They occupy less roof space for the same output and have better performance in low-light conditions. Most quality installations use mono PERC panels.
Bifacial panels generate electricity from both front and back surfaces, capturing reflected light. They cost 10 to 15 percent more than standard mono PERC and work best on white or highly reflective rooftops. Not always justified for standard residential applications.
Inverter type
String inverters are the most common for residential systems. One inverter handles the entire array. Cost-effective and reliable. Efficiency typically 96 to 98 percent.
Microinverters are installed on each individual panel, optimising performance independently. Better for roofs with shading issues. Significantly more expensive. Rarely cost-justified for standard residential rooftops in India.
Hybrid inverters support battery storage in addition to grid connectivity. More expensive upfront but necessary if you want power backup during grid outages. Increasingly popular in 2026 as battery prices fall.
Brand tier
Indian solar panel brands like Adani Solar, Waaree, Vikram Solar, RenewSys, and Premier Energies offer quality products at competitive prices. Imported brands from Tier 1 Chinese manufacturers (Longi, Jinko, Trina) are also widely available and competitively priced after import duties.
Inverter brands like SolarEdge, Sungrow, Growatt, Fronius, and Delta are commonly used in quality installations.
City and location
Installation costs in Mumbai and Delhi are typically 10 to 20 percent higher than in Jaipur, Nagpur, or Bhopal. This reflects both labour costs and logistics.
Cost per kW: what is a fair benchmark?
In 2026, a reasonable fully installed cost for a quality residential system using mono PERC panels and a reputable string inverter is Rs 50,000 to Rs 65,000 per kW before subsidy in most Indian cities.
If a quote comes in below Rs 45,000 per kW, ask detailed questions about panel brand, inverter make and model, and warranty terms. Low-cost quotes often compromise on inverter quality, which is the component most likely to fail within the system’s 25-year life.
If a quote exceeds Rs 75,000 per kW without clear justification (premium panel brand, hybrid inverter, complex installation), it warrants comparison with other installers.
How solar panel prices have changed
Solar module prices have fallen approximately 90 percent over the past decade globally. In India, the trajectory has been significant though modified by import duties introduced in 2022 (the Basic Customs Duty of 40 percent on imported solar modules and 25 percent on cells).
The import duty has supported domestic manufacturing, with companies like Adani Solar, Waaree, and Vikram Solar expanding capacity significantly. Domestic module prices remain somewhat higher than unprotected global benchmarks, but the overall system cost has continued to decline modestly in 2024 and 2025 as domestic manufacturing scales up.
In 2026, module prices per watt for quality domestic panels are in the range of Rs 20 to Rs 28 per watt depending on technology and brand.
What is not included in most quotes
Watch for these items that some installers leave out of their initial quote:
Net meter charges: Your DISCOM charges a fee for replacing your existing meter with a bidirectional net meter. This is typically Rs 2,000 to Rs 8,000 depending on your state and DISCOM.
Earthing and lightning protection: Quality installations include proper earthing. Some cut-price installers skip or minimise this. Confirm it is included.
Civil work for mounting: On some rooftop types, additional civil work is needed to anchor the mounting structure safely. This can add Rs 5,000 to Rs 20,000 depending on roof type.
Annual maintenance contract: Most reputed installers offer a 5-year AMC. Clarify whether this is included or charged separately.
Getting a fair quote: three things to always ask
First, ask for a detailed bill of materials — panel brand, model, and wattage, inverter brand and model, and mounting structure type. A reputable installer will provide this without hesitation.
Second, ask for the Performance Ratio guarantee in writing. A quality system should deliver a Performance Ratio of at least 75 percent annually in Indian conditions.
Third, ask for references of installations in your city or town completed in the last 12 months. Check whether the installer is registered on the PM Surya Ghar portal before signing anything.
Summing up
Solar system prices in India have fallen substantially and the PM Surya Ghar subsidy makes the net cost significantly more attractive. A 3 kW system after the Rs 78,000 central subsidy can be installed for Rs 75,000 to Rs 1.25 lakh in most cities. The key to getting value is understanding what is in the quote, comparing multiple registered installers, and not accepting the cheapest quote without scrutinising what has been cut.
