How Much Does a 10kW Solar System Price in India (2025)?
The price of a 10kW solar system in India depends on the type of system you choose:
- On-Grid Solar System (most common, connected to the electricity grid)
- Price: ₹4.5 lakh – ₹6 lakh
- After subsidy: ₹3.5 lakh – ₹4.5 lakh
- Ideal for: Homes, offices, schools, and businesses where grid electricity is available.
- Off-Grid Solar System (works with batteries, independent of grid)
- Price: ₹7.5 lakh – ₹9 lakh
- No subsidy (subsidy is generally not provided for off-grid)
- Ideal for: Remote areas with unreliable or no grid electricity.
- Hybrid Solar System (grid + battery backup)
- Price: ₹8 lakh – ₹10 lakh
- Limited subsidies, depending on state policy
- Ideal for: Businesses or homes that need backup during power cuts.
Key Takeaway:
A 10kW on-grid solar system in India costs ₹3.5–4.5 lakh after subsidy, generates 40–45 units daily, saves ₹1.2 lakh annually, and pays for itself in just 3–5 years.
Government Subsidy for 10kW Solar System in India (2025)
The PM Surya Ghar: Muft Bijli Yojana and various state-level subsidy programs support solar adoption in India.
Here’s how the subsidy typically works:
- Up to 2kW system: 60% subsidy on benchmark cost
- Above 2kW to 3kW: 40% subsidy
- Above 3kW to 10kW: 20% subsidy (capped at ₹78,000 to ₹1.2 lakh depending on DISCOM/state)
For a 10kW solar system, you can expect a subsidy of around ₹70,000 – ₹1.2 lakh.
This brings the effective cost of a 10kW on-grid solar system down to ₹3.5 lakh – ₹4.5 lakh.
Electricity Generation of a 10kW Solar System
A well-installed 10kW solar system in India generates:
- 40–45 units per day (average)
- 1,200–1,400 units per month
- 14,000–16,500 units per year
💡 If your electricity rate is ₹8 per unit, this means annual savings of:
