Rooftop solar costs, savings, and payback in India

The only question that matters for most families: after subsidy, will the system pay for itself in a sensible time? Tariff slabs differ by DISCOM — always start from your bill.

What you pay vs what you get back

Gross cost is what the installer quotes for panels, inverter, structure, wiring, and related work (before subsidy).

Subsidy (up to ₹78,000) is credited to your bank after commissioning if you qualify under PM Surya Ghar.

Net cost ≈ gross cost − subsidy. That is the investment your monthly bill savings should recover.

Payback ≈ net cost ÷ yearly savings. Under about 5 years is usually attractive for a home with a solid bill; beyond 7–8 years many families wait.

Indicative ranges using domestic tariff logic (~₹63k–₹65k per kW gross; 3 kW ≈ ₹1,90,000 before CFA). Sun hours and slabs vary by city. Your quote will differ — run the free check.

Gross moves with module brand, structure, and labour. Always compare written quotes.

When solar is usually worth it

  • Monthly bill roughly ₹2,500+ (stronger case)
  • You own the roof (or family roof with consent)
  • Enough unshaded terrace for the size you need
  • You plan to stay in the house for several years

When to wait

  • Very low bill (savings cannot recover net cost soon)
  • Tenant without owner approval
  • Roof about to be rebuilt or heavily shaded
  • You already claimed central rooftop subsidy there

FAQ

Money questions

Are there loans?

Many banks and NBFCs offer solar loans; some schemes advertise collateral-free options. Terms change — ask your bank or installer. Loan interest affects true payback.

Does generation stay the same for 25 years?

Panels degrade slowly (often ~0.5–0.7% per year in warranties). Year-1 savings are higher than year-20. Good vendors explain warranty and O&M.

Maintenance cost?

Mostly cleaning dust and occasional checks. Budget a small annual amount; ask the installer what is included.
