How to use this tool
Enter your solar panel capacity (in Wp or panel count), your yearly consumption and your EV kilometres. The tool works out how much of your solar power can go into the car.
How to read the result
The saving mainly comes from using your solar power yourself instead of feeding it back — especially as net metering is phased out. The more you charge during the day or smartly scheduled, the closer you get to the shown amount.
All outcomes are an indication based on your input — not a quote or guarantee.
