If you drive an electric scooter or car, your electricity use has just gone up, and a rooftop system is the cheapest way to pay for it.
The numbers
A scooter driven 30 km a day uses about one unit. A car driven the same distance uses about four. Each kW of rooftop solar produces about four units a day, so a car adds roughly 1 kW to the system you would otherwise need.
Charging at night
Under net metering, daytime surplus is credited against night use. Under the newer net-billing arrangements in Kerala, ask how your credit is valued before you plan to charge entirely at night.

Always verify. Subsidy, tariff and price figures change; confirm with the official portal, KSEB / TNPDCL and a written quote.
