Solar Payback & ROI Calculator
Rooftop solar is a long-term investment — the question is when it pays back. Enter your system, cost, subsidy and tariff to see the net cost, the yearly bill savings, the break-even and the lifetime savings.
India averages ~1,300-1,600 units per kW a year by region and shading.
Net cost Rs 87,000 after subsidy; saves about Rs 33,600 a year.
Indicative only. Real payback depends on your actual generation (shading, orientation, soiling), your tariff slab, net-metering rules, the current subsidy and battery costs if any. This assumes generation offsets consumption at your tariff and ignores tariff escalation. Get itemised local quotes, confirm the subsidy officially, and treat this as a planning estimate, not a guarantee.
