5kW Solar Panel Price in India: Full Cost Breakdown
The 5 kw solar panel price in India ranges from ₹2.5 lakh to ₹3.5 lakh for a standard on-grid installation in 2026, before subsidy. The figure most buyers miss: the PM Surya Ghar Muft Bijli Yojana subsidy is capped at ₹78,000 regardless of whether you install 3kW or 5kW. This means a 5kW system receives the same rupee subsidy as a 3kW one, but at a higher total outlay. The subsidy covers roughly 28% of a ₹2.8 lakh system, compared to 47% for a ₹1.65 lakh 3kW system.
All prices are indicative for 2026. Verify with MNRE-empanelled installers before committing.

5kW Solar System Price by Configuration
System Type | Approx. Cost (Before Subsidy) | Subsidy | Net Cost |
|---|---|---|---|
On-grid | ₹2.50 – ₹3.00 lakh | ₹78,000 | ₹1.72 – ₹2.22 lakh |
Hybrid (with battery) | ₹3.50 – ₹4.80 lakh | ₹78,000 (on panels + inverter) | ₹2.72 – ₹4.02 lakh |
Off-grid | ₹3.80 – ₹5.50 lakh | Not eligible | Full cost |
The on-grid system is the most common choice for urban homes with stable grid supply. It generates power during the day, offsets your bill via net metering, and exports surplus units to the grid for credit. No batteries, no backup during outages, but the fastest payback.
A hybrid system costs significantly more, mostly because of the battery. A 10kWh lithium battery bank adds roughly ₹80,000 to ₹1.5 lakh to the system cost. For homes in areas with long daily power cuts, the backup value can justify this. For urban homes with fewer than 30 minutes of daily outage, it usually does not.
5kW Solar System Cost: What the Price Includes
Component | Approximate Cost Share |
|---|---|
Solar panels (10–14 panels) | 50 – 55% |
On-grid / hybrid inverter or Solar PCU | 18 – 22% |
Mounting structure | 8 – 10% |
Wiring, protection, switchgear | 7 – 9% |
Installation and commissioning | 5 – 7% |
DISCOM and net meter fees | 2 – 4% |
Panel technology choice is where prices diverge most. Mono PERC panels are the standard mid-range option. TOPCon (N-type) panels cost more per watt but generate 3 to 5% more power from the same roof area. For a 5kW system on a space-constrained rooftop, TOPCon panels can mean fitting the required output in fewer panels.
For homes looking at paired battery storage, Adwin's solar power systems and Solar PCU inverter range are worth comparing.
The Key Fact Most 5kW Solar Guides Don't Tell You
The PM Surya Ghar subsidy is capped at the 3kW level. Installing 5kW does not earn you extra subsidy. Here is the financial impact:
System Size | Total Cost | Subsidy | Net Cost | Subsidy as % of Cost |
|---|---|---|---|---|
3kW | ₹1.65 lakh | ₹78,000 | ₹87,000 | 47% |
5kW | ₹2.80 lakh | ₹78,000 | ₹2.02 lakh | 28% |
10kW | ₹5.50 lakh | ₹78,000 | ₹4.72 lakh | 14% |
If your monthly electricity bill is below ₹2,500 to ₹3,000, a 5kW system will produce more electricity than you use, and the excess goes back to the grid. Whether that surplus is worth ₹1.15 lakh more than a 3kW system depends entirely on your grid's net metering rate and your future consumption growth.
The honest calculation: 5kW makes most sense when your current monthly bill is above ₹4,000 to ₹5,000, or when you expect electricity consumption to increase (new AC, EV charging, etc.).
What a 5kW System Can Run
Generating 20 to 25 units per day, a 5kW system supports:
- Multiple ACs (up to two 1.5-ton units running simultaneously during daylight hours)
- All fans and lights in a 3 BHK to 4 BHK home
- A refrigerator, washing machine, and dishwasher
- A water pump and other high-draw appliances
- Work-from-home equipment and entertainment systems
This capacity suits a 3 BHK to 4 BHK home with regular AC use, or a small business with daytime electrical load. It is not necessary for a home with minimal AC and an existing monthly bill under ₹2,000.
5kW Solar System Cost vs Monthly Bill: When It Makes Sense
Monthly Electricity Bill | Recommended System | Reason |
|---|---|---|
Under ₹2,000 | 1 – 2kW | 5kW will oversupply; ROI diluted |
₹2,000 – ₹4,000 | 3kW | Best subsidy-to-cost ratio |
₹4,000 – ₹8,000 | 5kW | Output matches consumption; good ROI |
Above ₹8,000 | 6 – 10kW | Higher system needed |

Pros and Cons of a 5kW Solar System
Pros:
- Generates 7,500 to 9,000 units per year, enough to offset a ₹4,000 to ₹8,000 monthly bill
- Supports two AC units simultaneously during peak sunlight hours
- Net metering credits surplus generation, effectively storing summer surplus for monsoon use
- Can add a battery later to convert to hybrid without replacing panels
Cons:
- Subsidy covers only 28% of cost (versus 47% for a 3kW system)
- Requires 400 to 500 sq. ft. of shadow-free roof space
- On-grid system provides no backup during power cuts
- Higher upfront investment with a longer payback period than a 3kW system at the same tariff rate
- DISCOM approval and net meter installation timelines can delay the subsidy credit
FAQs: 5kW Solar Panel Price India
What is the 5kW solar panel price in India in 2026? A 5kW on-grid solar system costs approximately ₹2.5 lakh to ₹3.5 lakh before subsidy in 2026. With the ₹78,000 PM Surya Ghar subsidy, the net cost falls to roughly ₹1.72 lakh to ₹2.72 lakh depending on the installer and panel technology.
What is the 5kW solar system cost in India with subsidy? The PM Surya Ghar subsidy for a 5kW system is ₹78,000, the same amount as for a 3kW system. The subsidy is capped at 3kW regardless of how large a system you install. Net cost after subsidy: approximately ₹1.72 lakh to ₹2.72 lakh for an on-grid system.
What is the 5kW solar system price in India with subsidy for hybrid systems? A 5kW hybrid system with battery storage costs ₹3.5 lakh to ₹4.8 lakh before subsidy. The ₹78,000 subsidy applies to panels and the inverter/PCU only, not the battery. Net cost is typically ₹2.72 lakh to ₹4.02 lakh.
How many units does a 5kW solar system produce per day? A 5kW solar system generates 20 to 25 units per day in good sunlight conditions. Monthly output is 600 to 750 units. This is typically enough to offset the electricity consumption of a 3 BHK to 4 BHK home with moderate AC use.
How much roof space does a 5kW solar system need? A 5kW solar system requires approximately 400 to 500 sq. ft. of shadow-free roof space, accommodating 10 to 14 solar panels depending on individual panel wattage (typically 380W to 550W per panel in 2026).
What is the payback period for a 5kW solar system in India? On-grid 5kW systems typically pay back in 4 to 6 years depending on your state tariff and the amount of solar power your home actually consumes versus what is exported to the grid. Hybrid systems take longer due to the higher initial battery cost.
Is 5kW enough for a 3 BHK house with AC? A 5kW system generating 20 to 25 units per day can comfortably run two 1.5-ton ACs during peak solar hours alongside other household appliances. For a single 1.5-ton AC and standard home load, a 3kW system is sufficient and offers better subsidy-to-cost value.
Can I run a 5kW solar system without batteries? Yes. An on-grid 5kW system operates without batteries by feeding surplus power to the grid. You draw from the grid at night or during cloudy weather and earn net metering credits for surplus exported. This is the lowest-cost configuration but provides no power during outages.
