If you're researching rooftop solar for your home in Delhi, the first thing you want to know is: how much will it cost? Let's break it down for the most popular system size — 3 KW — which is ideal for most 2-3 BHK homes.
Total System Cost (Before Subsidy)
A 3 KW on-grid rooftop solar system in Delhi typically costs between Rs 1,80,000 to Rs 2,20,000 including installation. This covers:
| Component | Approximate Cost | |---|---| | Solar panels (3 KW) | Rs 75,000 – 90,000 | | Inverter (string/micro) | Rs 30,000 – 45,000 | | Mounting structure | Rs 15,000 – 20,000 | | Wiring, earthing, SPD, lightning arrestor | Rs 15,000 – 20,000 | | Installation & labour | Rs 15,000 – 20,000 | | Net meter & DISCOM coordination | Rs 10,000 – 15,000 | | Total | Rs 1,80,000 – 2,20,000 |
Prices vary based on panel brand (Adani, Vikram, etc.), inverter type, and roof complexity.
Government Subsidies You Can Claim
Delhi residents get two subsidies that dramatically reduce the cost:
1. PM Surya Ghar Yojana (Central Government)
For a 3 KW system, you get Rs 78,000 in subsidy:
- First 2 KW: Rs 30,000/KW = Rs 60,000
- Next 1 KW: Rs 18,000/KW = Rs 18,000
- Total: Rs 78,000 (disbursed via DBT to your bank account)
2. Delhi State Subsidy
The Delhi government provides an additional Rs 2,000 per KW plus a Rs 30,000 bonus for 3 KW systems:
- 3 KW × Rs 2,000 = Rs 6,000
- Bonus for 3 KW: Rs 30,000
- Total: Up to Rs 30,000 (disbursed after commissioning)
Combined Subsidy
| Subsidy | Amount | |---|---| | PM Surya Ghar (Central) | Rs 78,000 | | Delhi State Subsidy | Up to Rs 30,000 | | Total Subsidy | Up to Rs 1,08,000 |
Your Net Cost After Subsidy
| | Amount | |---|---| | System cost | Rs 1,80,000 – 2,20,000 | | Minus total subsidy | Rs 1,08,000 | | Your net cost | Rs 70,000 – 1,10,000 |
That's your total out-of-pocket cost for a system that will generate free electricity for 25+ years.
What About EMI / Financing?
If you don't want to pay the full amount upfront, solar loans are available from several banks. Typical terms:
- Loan amount: Rs 1.5 – 2 lakh (pre-subsidy)
- Interest rate: 7 – 9% per annum
- Tenure: 3 – 5 years
- EMI: Roughly Rs 3,500 – 4,500/month for a 5-year loan
In most cases, your EMI will be less than your current electricity bill, so you start saving from month one.
What's the Payback Period?
With a 3 KW system generating approximately 360 units/month:
- Monthly electricity savings: 360 × Rs 7 = Rs 2,520
- Monthly GBI income: 360 × Rs 3 = Rs 1,080
- Total monthly benefit: Rs 3,600
- Annual benefit: Rs 43,200
At a net cost of Rs 70,000 – 1,10,000, your payback period is under 3 years. After that, it's all profit for the remaining 22+ years of panel life.
