Free Solar System Explained: How You Pay Almost Nothing and Get Free Electricity for Years
Many people think installing a solar system means spending a lot of money upfront.
But in reality, with government subsidy + solar finance, solar can feel almost FREE.
Let’s understand this with a real-life 3 kW rooftop solar example that anyone can understand.
What Do We Mean by “Free Solar System”?
“Free solar” does NOT mean zero cost from day one.
It means:
- Your monthly EMI ≈ your current electricity bill
- You stop paying high electricity bills
- After a few years, EMI ends
- And then you enjoy free electricity for 15–20+ years
So instead of paying money to the electricity company forever,
you pay almost the same amount for a few years, and then power becomes free.
Example System: 3 kW Rooftop Solar (600W × 5 Panels)
- System size: 3 kW
- Panels used: 600W high-efficiency panels
- Ideal for homes with ₹2,000–₹3,500 monthly electricity bills
- Suitable for Delhi, UP, Haryana, Uttarakhand homes
Step 1: Solar System Cost Before Subsidy (Approximate)
| State | 3 kW System Cost (Before Subsidy) |
|---|---|
| Delhi | ₹2,00,000 |
| Uttarakhand | ₹1,90,000 |
| Uttar Pradesh | ₹1,90,000 |
| Haryana | ₹1,85,000 |
(This includes panels, inverter, structure, wiring, installation, and approvals)
Step 2: Government Subsidy You Get (Direct Benefit)
| State | Govt Subsidy Amount |
|---|---|
| Delhi | ₹1,08,000 |
| Uttarakhand | ₹85,800 |
| Uttar Pradesh | ₹1,08,000 |
| Haryana | ₹78,000 |
This subsidy is credited directly to your bank account after installation.
Step 3: Solar Finance – How EMI Works
Most families do not pay the full amount upfront.
Typical Finance Structure (Delhi Example)
- Project price: ₹2,00,000
- Down payment (10%): ₹20,000
- Loan amount (90%): ₹1,80,000
- Interest rate: ~6% per annum
- Loan tenure: 10 years
Step 4: Monthly EMI vs Electricity Bill
- Approx EMI: ₹2,000 – ₹2,300 per month
- Average old electricity bill: ₹2,000 – ₹3,000 per month
👉 That means:
You simply replace your electricity bill with a solar EMI.
Electricity bill never ends.
Solar EMI ends after a few years.
Step 5: How Subsidy Makes Solar Feel Almost Free
The ₹1,08,000 subsidy (Delhi) can be used to:
- Prepay the loan principal
- Reduce EMI duration
- Or close the loan early
So effectively:
- You pay EMI for a shorter time
- Then electricity becomes 100% free
One-Table Summary: “Free Solar” Explained Simply
| Item | Explanation |
|---|---|
| System Size | 3 kW (600W × 5 panels) |
| System Cost (Delhi) | ₹2,00,000 |
| Govt Subsidy | ₹1,08,000 |

What Happens After EMI Ends?
- No electricity bill
- No EMI
- Only minor maintenance
- Free power for 15–20+ years
Over time, a 3 kW system can save ₹8–10 lakh in electricity costs.
Why This Makes Sense Emotionally and Logically
Emotionally:
- Relief from rising power bills
- Energy independence
- Clean power for your family
Logically:
- Same monthly outflow as electricity
- Asset creation instead of expense
- Guaranteed long-term savings
Final Thought: Why Keep Paying Bills Forever?
Electricity bills go up every year.
Solar EMI goes down to zero.
If you are already paying ₹2,000–₹3,000 every month for electricity,
why not pay the same amount for a few years and then enjoy
free power for decades?
That is why people call it “Free Solar System”.
