How Solar Home EV Charging Works

  1. Daytime Solar Charging: When the sun is out, solar panels directly power your home and the EV charger simultaneously.
  2. Battery-Based Charging: If excess power is generated, it is stored in a home battery (like Tesla Powerwall or Amara Raja Sunbox).
  3. Nighttime/Cloudy Days: The system automatically pulls stored solar energy or grid power as a backup source.
  4. Net Metering Option: Surplus electricity is exported to the grid, earning credits that offset your bill.​

Real-Life Example: Solar EV Charging in Bengaluru

Raghav, a tech professional from Bengaluru, installed a 5 kW solar rooftop system with a 7.4 kW Type-2 home charger for his Tata Nexon EV. On average, his EV drives 40 km daily, costing him nothing in energy bills. The rooftop system powers household appliances and the EV simultaneously. His setup reduced monthly charging costs from ₹1,800 to almost zero, while also contributing to lowering his carbon footprint by 1.5 tons annually.​

Environmental Impact: A Greener Home and Cleaner Planet

Solar-powered EV charging reduces emissions not only from vehicle operation but also from grid-based electricity generation. Every EV charged by sunlight prevents approximately 1.5–2 tons of CO₂ emissions per year—equivalent to planting nearly 40 trees annually.​

Widespread adoption of this combination will significantly help India achieve its net-zero 2070 target, reduce reliance on coal imports, and create thousands of green jobs in the renewable energy sector.​
