your EV can partially or fully run using:

☀️ sunlight.

⚡ How the System Works

Simple flow:

☀️ Solar Panels
→ ⚡ Inverter
→ 🔋 Home/EV Charging System
→ 🚗 Electric Vehicle

Extra electricity can:

power the home
charge batteries
export to BESCOM grid through net metering

🇮🇳 Why Solar EV Charging Is Growing Fast in India
