For a subsidised residential rooftop system, payback is typically 3–4 years. Larger systems above the ₹78,000 subsidy cap, or lower tariffs, can push it slightly longer.
Payback = net cost (after subsidy) ÷ yearly savings. Yearly savings ≈ the units your system generates × your tariff. After payback, the electricity is effectively free.
Because a system pays back in a few years and then runs ~25 years, the effective annual return is often 20–30%+ — usually far better than an FD, and it is tax-free savings.
Maintenance for rooftop solar is low (mainly cleaning). This estimate ignores small O&M costs and any tariff rises, so treat it as indicative.
