The 3kW solar panel price in India is about ₹2.1–2.2 lakh before subsidy in mid-2026, and roughly ₹1.3–1.5 lakh after the central PM Surya Ghar subsidy of ₹78,000. A 3kW rooftop system produces about 330–450 units a month, depending on your city. As a result, most households recover the cost in three to five years and then enjoy free power for the rest of the panels’ life.
Key Takeaways
- Price range: ₹1.8–₹2.3 lakh before subsidy for a good-quality, grid-connected 3kW system.
- Subsidy: ₹78,000 from the central government, which cuts the net cost to about ₹1.3–1.5 lakh.
- Output: 12–15 units a day, or 330–450 units a month.
- Roof space: about 250–300 square feet of shadow-free area.
- Payback: roughly three to five years after subsidy.
What Is the 3kW Solar Panel Price in Indian Cities?
The 3kW solar panel price varies by city because of logistics, local competition and DISCOM fees. SolarSquare’s July 2026 city listings give a useful snapshot. They quote a 3kW system with installation at the prices below, and each figure drops sharply once the subsidy applies.
| City | Price before subsidy | Approx. price after ₹78,000 subsidy |
|---|---|---|
| Pune | ₹2.15 lakh | ₹1.37 lakh |
| Hyderabad | ₹2.13 lakh | ₹1.35 lakh |
| Ahmedabad and Surat | ₹2.10 lakh | ₹1.32 lakh |
| Bhopal | ₹2.23 lakh | ₹1.45 lakh |
These numbers come from an installer’s own pricing pages, so treat them as indicative. A separate estimator puts the all-in range wider, at ₹1.6–₹2.2 lakh before subsidy. Therefore, always collect at least three written quotes. Our broader guide to the solar panel price in India explains per-watt rates and GST in more detail.
What a 3kW Quote Should Include
A fair 3kW solar panel price quote lists every component and the work behind it. Check that your quote covers these items.
| Component | Typical share of cost | What to confirm |
|---|---|---|
| Solar panels (5–6 modules) | 45–50% | Brand, wattage, ALMM listing, warranty |
| On-grid inverter | 12–15% | Brand, 5–10 year warranty |
| Mounting structure | 10–12% | Galvanised steel, wind rating |
| Cables, earthing, protection | 8–10% | Copper cables, surge protection |
| Installation, net metering, paperwork | 10–15% | Who handles DISCOM and subsidy |
How Much Subsidy Do You Get on a 3kW System?
The central government pays ₹30,000 per kW for the first 2kW and ₹18,000 for the third kW. Therefore, a 3kW system earns ₹78,000, and this is also the maximum for larger systems. The scheme covers grid-connected residential rooftops only.
However, you must meet a few conditions. You need a valid electricity connection in your name, and you must own the roof or hold the owner’s consent. Moreover, the panels must be domestically made and listed on the Approved List of Models and Manufacturers (ALMM). From 1 June 2026, the cells inside the panels must also come from ALMM List-II manufacturers.
A non-compliant panel can make your application fail at inspection. Consequently, ask your installer for the exact model number, and check it on the MNRE website. You can then apply through the national portal, as our PM Surya Ghar Yojana guide explains step by step.
How Many Units Does a 3kW Solar System Generate?
A well-placed 3kW system produces about 12–15 units a day in sunny states. Monthly generation depends heavily on your region, as the table shows.
| Region type | Example states | Approx. monthly output (3kW) |
|---|---|---|
| High sunshine | Rajasthan, Gujarat, Madhya Pradesh | 330–360 units (up to 450 in peak months) |
| Average sunshine | Maharashtra, Karnataka, Telangana | 300–330 units |
| Lower sunshine | North-East, hill regions | 260–300 units |
Output also falls with shading, dust and poor tilt. Because dust can cut generation by 10–15%, regular cleaning pays off. If your meter shows a sudden drop, read our guide on solar panel output dropping.
How Many Solar Panels Does a 3kW System Need?
A 3kW system needs five or six panels of 540–580 W each. Six 550 W panels give 3.3kW, which is the common choice. Each panel measures about 2.3 by 1.1 metres, so the array covers roughly 250–300 square feet of shadow-free roof. Shade from water tanks, parapets or neighbouring buildings matters more than the raw area.
3kW Solar Savings and Payback Period
Savings depend on your tariff and consumption. A 3kW system can cover most of the bill for a home that uses 300–400 units a month.
| Monthly consumption | Approx. units from solar | Typical monthly bill saving | Net payback (after subsidy) |
|---|---|---|---|
| 250 units | ~250 | ₹1,800–₹2,500 | 4–6 years |
| 350 units | ~340 | ₹2,800–₹3,800 | 3–5 years |
| 450 units | ~400 | ₹3,200–₹4,500 | 3–4 years |
These figures assume tariffs of ₹7–₹10 per unit including fixed charges and duties. Your slab rates may differ. Use our Solar Panel Savings Calculator to test your own bill. Panels carry a 25-year performance warranty, so you get about 20 years of nearly free electricity after payback.
What Can a 3kW Solar System Run?
A 3kW array can power a typical urban home during daylight. Net metering then supplies power from the grid at night. The table below shows approximate loads.
| Appliance | Approx. running load |
|---|---|
| 1.5-ton inverter air conditioner | 0.9–1.5 kW |
| Refrigerator | 0.15–0.25 kW |
| Ceiling fans (4) | 0.2–0.3 kW |
| LED lights (10) | 0.1 kW |
| Washing machine | 0.5 kW |
| Geyser | 1.5–2.0 kW |
Running a geyser and an air conditioner together can exceed 3kW, so the grid supplies the extra. That is normal and does not harm the system.
Should You Add a Battery to a 3kW System?
A battery adds ₹60,000–₹1.2 lakh and pushes the total to roughly ₹2.4–3 lakh. Battery-based systems also do not qualify for the central subsidy. Most city homes with reliable grids should skip storage. If you face long outages, a hybrid system makes sense, and our solar battery guide explains the trade-offs.
Is 3kW the Right Size for Your Home?
Before you compare the 3kW solar panel price across vendors, confirm that 3kW actually suits your usage. Use this quick rule. Divide your yearly electricity use by about 1,500 to estimate the kW you need. A home using 4,200 units a year needs roughly 2.8kW, so 3kW fits well. A home using 7,000 units needs about 4.7kW, so consider 5kW. Compare options in our guide to solar panel installation costs.
Remember that the subsidy stops at 3kW. Beyond that, each extra kW costs full price, though it still saves money if your usage is high. Plan for future needs such as a second air conditioner or an electric vehicle.
How to Buy a 3kW Solar System Step by Step
- Check your bills. Note six months of units and tariffs.
- Inspect your roof. Measure free area and check for shade.
- Register on the national portal. Use your consumer number and mobile.
- Compare quotes. Select an empanelled vendor with local references.
- Install and commission. Complete net metering and inspection.
- Claim the subsidy. Submit bank details and the commissioning report.
Banks also offer concessional loans for rooftop solar, so a small down payment can start the process. Avoid paying more than 30–40% in advance. Pay the balance after commissioning and meter installation.
Final Thoughts on the 3kW Solar Panel Price
The 3kW solar panel price looks high on paper, yet the numbers work for most homes. After subsidy, you pay roughly ₹1.3–1.5 lakh and save ₹2,800–₹4,500 a month. Choose ALMM-compliant panels, a trusted inverter and an installer who handles the paperwork.

What is the 3kW solar panel price in India?
A 3kW grid-connected system costs about ₹1.8–₹2.3 lakh before subsidy in 2026. City listings in July 2026 showed about ₹2.1–₹2.2 lakh, and the net cost after subsidy was roughly ₹1.3–₹1.5 lakh.
How much subsidy do I get on a 3kW solar system?
You get ₹78,000 under PM Surya Ghar. The scheme pays ₹30,000 per kW for the first 2kW and ₹18,000 for the third kW.
How many units does a 3kW solar panel produce?
It produces about 12–15 units a day in sunny states, or 330–450 units a month. Output varies with location, tilt, shading and cleanliness.
How many solar panels are needed for 3kW?
You need five or six panels of 540–580 W each. Six panels of 550 W make a 3.3kW array on about 250–300 square feet of roof.
Can a 3kW solar system run an air conditioner?
Yes. It can run one or two inverter air conditioners during the day along with lights, fans and a refrigerator. The grid supplies any extra load, and net metering handles night use.
