The only question that matters for most families: after subsidy, will the system pay for itself in a sensible time?
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.

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