Solar + an electric vehicle (EV) is a match made in heaven
Here's another way to think about solar and your EV. Sweet Spot Solar did this 4.5 kW array in Salmon Arm BC recently for $12,500. It will make approximately 5000 kWh/year of energy. In an EV, that amount of energy will cover about 20,000 km/year of driving. If you drove a non EV and used 8 l/100 km of gas or diesel (pretty average), you would buy 1600 litres per year. At $1.35/litre this would cost you $2160/year. A solar array like this would pay for itself in 6 years assuming gas doesn't go up!
We can install an EV charging station for you too.
