So I drive about 72 miles each way to work. My total commute takes about 3 hours round trip depending on traffic. Does anybody have the idea of electric cost I will carry? Musk has said Model 3 will have a 75 kWh pack which will allow for 215 miles on single charge which means I will need to charge every night just about. Tesla has the cost at about $6 a day which in total for a week will be half the cost of gas. But how much will solar save me? What is the cost of supercharging for those that don't have it free?
