Another Leaf driver here, 2017 30kwh model. We installed 5.7 kW of solar PV on our house at the same time as getting the car. Combined cost of solar / car payment is less that we were paying for VED and fuel for the 3l Subaru that we replaced.
This setup has provided 90% of the electricity for our house AND local driving during spring and summer.
If you can do the same I would really recommend it.
Also had a melted extension lead plug during the winter. 5m extension lead with 3 pin Leaf charger...... glad nothing went on fire.
