Solar ROI and Payback Period in India

Residential solar payback in central India typically ranges from 3 to 5 years depending on system size, tariff slab, and self-consumption ratio. Higher electricity bills shorten payback because each generated unit displaces expensive grid power.

A 3 kW system for a home with a ₹3,000 monthly bill can save roughly ₹2,500 per month after installation. Over 25 years, lifetime savings often exceed system cost by 4–6 times.
