ROI of Solar Panels in India – Complete 2025 ROI Calculation
“What is the ROI of solar?”
This is the first question every homeowner asks — and the answer is surprisingly good.
Solar provides one of the highest ROIs in India, even better than mutual funds, SIPs, fixed deposits, or real estate rentals.
Let’s break it down with real numbers.
What Is Solar ROI in India (2025)?
Solar ROI = Savings per year / Cost of system × 100
For a typical 5kW solar system:
- Cost: ₹2,15,000–₹2,60,000
- Savings: ₹4,000–₹8,000/month
- Annual savings: ₹48,000–₹96,000
ROI = 18% – 45% per year
This is extremely high compared to:
- FD returns → 6–7%
- SIP returns → 12–15%
- Rental income → 2–3%
Why Solar ROI Is So High in India
High sun exposure
300–320 sunny days.
High electricity tariff
₹7–₹10 per unit in most states.
Long panel life
25+ years life with zero running cost.
