2BHK Solar System Cost in India: Price, Capacity, and ROI Guide for Beginners
2BHK Solar System Cost in India: Price, Capacity, and ROI Guide for Beginners
A 2BHK apartment or home in India typically requires a 2kW to 3kW solar system to meet daily electricity needs efficiently. Understanding the costs, system types, and return on investment helps you make an informed decision about solar adoption.
Recommended System Capacity for 2BHK Homes
For a typical 2BHK household consuming 200-300 units per month, a 2-3kW solar system is ideal. A 2kW system generates approximately 240-280 units monthly, while a 3kW system produces 360-420 units, covering most residential electricity requirements.
Solar System Prices for 2BHK Homes
The cost varies based on system type—on-grid, off-grid, or hybrid—and location. Here’s a comprehensive breakdown for 2025:
2kW Solar System Prices
| System Type | Price Without Subsidy | Government Subsidy | Price After Subsidy |
|---|---|---|---|
| On-grid | ₹1,44,000 – ₹1,75,000 | ₹60,000 | ₹84,000 – ₹1,15,000 |
| Off-grid | ₹1,60,000 – ₹2,00,000 | Not Applicable | No change |
| Hybrid | ₹1,75,000 – ₹3,00,000 | ₹60,000 | ₹1,15,000 – ₹2,40,000 |
3kW Solar System Prices
| System Type | Price Without Subsidy | Government Subsidy | Price After Subsidy |
|---|---|---|---|
| On-grid | ₹2,10,000 – ₹2,43,000 | ₹78,000 | ₹1,32,000 – ₹1,65,000 |
| Off-grid | ₹2,40,000 – ₹2,70,000 | Not Applicable | No change |
| Hybrid | ₹2,70,000 – ₹3,15,000 | ₹78,000 | ₹1,92,000 – ₹2,37,000 |
Understanding System Types
On-grid systems connect to the electricity grid and support net metering, allowing you to export surplus power and reduce bills. These are the most affordable option with subsidy benefits.
Off-grid systems include battery storage for complete energy independence, ideal for areas with unreliable grid supply. However, they cost more and don’t qualify for government subsidies.
Hybrid systems combine grid connection with battery backup, offering flexibility during power cuts while maintaining net metering benefits. They qualify for subsidies on the solar panel and inverter components.
Government Subsidies Available
Under the PM Surya Ghar Muft Bijli Yojana, residential consumers receive substantial subsidies:
- 2kW system: ₹60,000 subsidy
- 3kW and above: ₹78,000 fixed subsidy
These subsidies apply only to on-grid and hybrid solar systems, not off-grid setups with batteries.
Return on Investment and Payback Period
Solar systems for 2BHK homes typically achieve payback within 5-8 years, depending on your electricity consumption and local tariffs.
Annual savings example: A 3kW system in Tamil Nadu can save ₹18,000-₹24,000 annually based on current electricity rates of ₹5-6 per unit. With a total investment of ₹1,65,000 (after subsidy), the system pays for itself in approximately 7 years, after which you enjoy free electricity for 18+ years.
Space Requirements
A 2kW system requires approximately 200 square feet of shadow-free rooftop space, while a 3kW system needs around 300 square feet. Ensure your rooftop receives adequate sunlight throughout the day for optimal performance.
