A Tunisian company is selling small electric vans whose rooftop solar generates enough energy to pay for the cost of the vehicle in 8 years.

“The solar cells provide us with more than 50% of our needs,” says Boubaker Siala, founder and CEO of Bako Motors. “For example, the B-Van, for commercial use, you can have free energy for about 50 kilometers (31 miles) per day… 17,000 kilometers (10,563 miles) per year. …….. The B-Van, which can carry 400 kilograms (882 pounds) of cargo and has a 100 to 300-kilometer (62 to 186 mile) range, is designed for logistics and last-mile delivery, with prices starting at 24,990 Tunisian dinar ($8,500)."

It varies widely by vehicle type, etc – but travelling 31 miles costs you in the ballpark of $3 in the US or €5 in Europe. So that's around $1,000/€1,800 of free fuel every year if you were using this vehicle most days. The B-Van is small, but perfect for local deliveries, especially if paired with swappable batteries.

You know what will never pay for itself with its self-generating fuel capacity? A gasoline combustion-engine car. Here's another pointer, they're rapidly becoming the transport option of yesteryear.
