Electric Vehicles (EVs) like the Tata Nexon and Ola S1 Pro are booming on the streets of Surat. They are smooth, quiet, and eco-friendly. But if you are plugging your new EV directly into your home's standard DGVCL/GEB grid connection, you might be in for a nasty surprise when your electricity bill arrives.
1. How Much Power Does an EV Actually Need?
Let's look at the math for a popular car like the Tata Nexon EV. It has a ~30kWh battery. To charge it from 0% to 100%, it requires roughly 30 to 32 units of electricity.
Grid Charging
- Assuming ₹7.5/unit
- Pushes your home into higher slab rates
- Subject to GEB price hikes
Solar Charging
- 100% Free Energy
- Truly zero carbon emissions
- Protects your home's standard slab rate
2. What Size Solar System Do You Need?
If you drive around 40-50 km daily, you use about 5 to 7 units of electricity specifically for your car.
A standard 3kW Solar Rooftop System generates approximately 12 to 15 units a day in Gujarat. This is generally enough to cover a standard household's daily lighting and AC needs, plus the daily top-up charge for your EV.
3. But Wait... I Only Charge My EV at Night!
This is the most common question we get: "Solar panels only generate power during the day while I'm at work. How can I charge my car at night for free?"
The Magic of Net Metering
You don't need expensive battery backups to charge your car at night! Under Gujarat's Net Metering policy, your solar panels send excess power to the GEB grid during the day. Think of the grid as a giant free battery. At night, when you plug your EV in, you pull that exact same power back from the grid. DGVCL automatically adjusts your export vs. import balance at the end of the month, meaning your night-time charging is 100% covered by your day-time generation.
Conclusion: If you are planning to buy an EV, or already own one, buying a solar system isn't just an option—it is a necessity to unlock the true financial benefits of electric driving. Contact Chidanand Solar to design an EV-ready system for your home.
