While charging an electric car from the grid already cuts fuel expenses by 70% compared to petrol or diesel, pairing your home EV charger with rooftop solar eliminates running costs altogether.
1. The Math: Solar Energy vs Petrol & Grid Power
Driving a petrol car costs ₹8–₹10/km. Charging an EV from regular grid power costs ₹1.50–₹2.00/km. When charged with surplus solar energy credited via TSSPDCL net-metering, your effective cost drops to under ₹0.40/km.
