Solar is a significant investment. Let's walk through a realistic ROI calculation for an average Indian household.
Example: Hyderabad Household - Monthly electricity bill: ₹3,000 - System required: 5kW - System cost (after subsidy): ₹2,20,000 - Annual savings: ₹36,000 - Payback period: ~6.1 years - System life: 25+ years - Total savings over 25 years: ~₹9,00,000
Factors That Improve ROI - Higher existing electricity bills (more to save) - Areas with high sun hours (5.5+ hrs/day in AP & Telangana) - Net metering availability in your DISCOM area - Government subsidies reducing upfront cost
Hidden Benefits - Increased property value (studies show 3–4% increase) - Protection from future electricity tariff hikes - Carbon credits in some commercial scenarios
Bottom Line In most South Indian cities, rooftop solar achieves payback in 4–7 years and provides 18+ years of essentially free electricity. It's one of the best financial decisions a homeowner can make.
