Solar energy is no longer a luxury in India it’s quickly becoming a necessity. With rising electricity bills, frequent power cuts in some regions, and the government pushing clean energy adoption, rooftop solar systems are now more affordable than ever.
For small households, a 2kW solar system is one of the most practical and cost-effective choices. It’s compact, affordable, and powerful enough to cut down a large part of your monthly electricity bill.
In this article, I’ll break down the 2kW solar system price in India (2025), explain how much subsidy you can get, share real-life case studies, and calculate the return on investment (ROI) you can expect.
Key Takeaways
- 2kW solar system price in India (2025): ₹1.2 – ₹1.4 lakh
- After subsidy: ₹50,000 – ₹60,000
- Generates 8–10 units/day → saves ₹1,800–₹2,500 monthly
- Payback in 2–3 years, with lifetime savings of ₹5+ lakh
- Best suited for small families or low-consumption homes
What is a 2kW Solar System?
A (2-kilowatt) 2kW Solar System Price in India can generate around 8–10 units of electricity per day, depending on your location and sunlight availability.
That’s enough to power:
- 3–4 ceiling fans
- 6–8 LED lights
- 1 refrigerator
- 1 washing machine
- 1 small air conditioner or water pump (part-time)
A typical 2kW system includes:
- 5–6 solar panels (each 350–450W)
- Inverter (DC to AC conversion)
- Mounting structures and wiring
- Optional battery backup (for power cuts)
It’s ideal for households with a monthly electricity bill of ₹1,500 – ₹2,500.
2 Kilowatt Solar System Price in India (2025)
The price varies depending on whether you go for on-grid, off-grid, or hybrid systems:
| Type of System | Price (Before Subsidy) | Best For |
|---|---|---|
| On-Grid (no batteries) | ₹1.2 – ₹1.4 lakh | Homes with stable electricity and net metering |
| Off-Grid (with batteries) | ₹1.5 – ₹1.7 lakh | Areas with frequent power cuts |
| Hybrid (grid + battery) | ₹1.7 – ₹1.9 lakh | Homes that want savings + backup |
Average on-grid 2kW Solar System Price in India price in India (2025): ~₹1.3 lakh
Subsidy on 2kW Solar System (2025)
Under the PM Surya Ghar: Muft Bijli Yojana, households get a 60% subsidy for solar systems up to 3kW capacity.
So for a 2kW system:
- Benchmark cost: ~₹1.3 lakh
- Subsidy amount (60%): ~₹78,000
- Net cost after subsidy: ~₹50,000 – ₹60,000
That’s a massive saving essentially reducing the cost by more than half.
Savings from a 2kW Solar System
A 2kW system generates 240–300 units per month, depending on sunlight.
- Monthly savings: ₹1,800 – ₹2,500
- Annual savings: ₹22,000 – ₹30,000
- Payback period: ~2–3 years
After that, you enjoy free power for the next 20+ years.
How to Apply for Subsidy
The process is simple:
- Visit the National Portal for Rooftop Solar → solarrooftop.gov.in.

Real-Life Case Studies
Here is 3 real life Case Studies in different scenario people living in India.
Case Study 1: A Small Family in Lucknow
The Mishra family had an average monthly electricity bill of ₹2,000. In 2024, they installed a 2kW on-grid solar system.
- System cost: ₹1.3 lakh
- Subsidy received: ₹78,000
- Net cost paid: ₹52,000
- Monthly savings: ₹2,000
- Payback period: 26 months
“Within just over 2 years, our solar panels had paid for themselves. Now we practically get electricity at zero cost,” says Mr. Mishra.
Case Study 2: Retired Couple in Pune
Mr. and Mrs. Kulkarni, both retired, wanted to reduce expenses and avoid frequent power cuts. They installed a 2kW off-grid system with batteries.
- System cost: ₹1.6 lakh
- Subsidy received: ₹78,000
- Net cost paid: ₹82,000
- Monthly savings: ₹2,200
- Extra benefit: Backup during 4–5 hours of power cuts
- Payback period: ~3 years
Case Study 3: Shop Owner in Patna
A small general store in Patna installed a 2kW hybrid solar system in early 2023. The system now powers lights, fans, and a refrigerator.
- System cost: ₹1.8 lakh
- Subsidy received: ₹78,000
- Net cost paid: ₹1.02 lakh
- Monthly savings: ₹2,500
- Payback period: ~3.5 years
The owner says his electricity bill dropped by 70%, which directly improved his shop’s profit margins.
ROI Example for a 2kW Solar System Price in India
Let’s calculate based on average values:
- System cost (before subsidy): ₹1.3 lakh
- Subsidy received: ₹78,000
- Net cost (after subsidy): ₹52,000
- Monthly savings: ₹2,000
- Annual savings: ₹24,000
Payback period = ₹52,000 ÷ ₹24,000 ≈ 2.2 years
Total lifetime savings (25 years) = (₹24,000 × 25) – ₹52,000 = ₹5.48 lakh
That’s more than 10x return on investment.
