Solar is an Investment, Not an Expense
Investing in a solar rooftop system under the PM Surya Ghar Yojana is fundamentally different from buying a car or an appliance.
Because solar panels generate electricity, they actually yield higher financial returns than most fixed deposits or mutual funds.
To truly understand the value you are getting in 2026, you need to calculate two critical things: your monthly loan EMI and your ROI payback period.
Part 1: Interactive Solar Loan EMI Calculator
Use the calculator below to find out exactly how much your monthly payments will be if you finance your solar system.
Monthly EMI
₹1,426
Part 2: Calculating Monthly Savings
A standard 3kW system in India generates roughly 360 units of electricity per month.
If your current DISCOM electricity tariff is ₹8 per unit, the math is simple:
Monthly Savings = 360 units × ₹8 = ₹2,880.
Part 3: The Cash Flow Analysis
This is where the PM Surya Ghar scheme becomes incredibly lucrative.
Let's compare your monthly EMI commitment to your monthly electricity savings.
- - You pay the bank: ₹1,426
- + You save on your bill: ₹2,880
- = Net Positive Cash Flow: ₹1,454
You are saving ₹1,454 *more* every single month than you are paying to the bank! From day one, the solar system is paying for its own loan and putting extra money in your pocket.
Part 4: The Payback Period (ROI)
What if you didn't take a loan and instead paid the ₹72,000 upfront out of pocket?
Upfront Cost: ₹72,000
Annual Savings: ₹34,560 (₹2,880 × 12 months)
Payback Period = 2.08 Years
Conclusion: Decades of Free Power
In just over 2 years, the solar system pays for itself entirely.
Since tier-1 solar panels have a guaranteed lifespan of 25 years, you will enjoy roughly 23 years of absolutely free electricity.
For a standard 3kW system, this equates to lifetime tax-free savings of over ₹8,00,000 to ₹10,00,000, solidifying rooftop solar as one of the safest and most lucrative investments any Indian homeowner can make in 2026.
