Zero-emission cars are soaring in popularity but running an electric vehicle is next to impossible in places with limited charging infrastructure. Stella Terra could change that. The khaki-green SUV uses solar panels on its sloping roof to charge its electric battery, meaning it can drive long distances powered entirely by the sun. Built by a team of students at Eindhoven University of Technology (TUE),“the world's first off-road solar-powered vehicle" could help connect remote areas “where roads are less developed and energy grids are not as reliable," and assist with emergency aid and deliveries, says Thieme Bosman, events manager for the team. 

The team tested the vehicle in Morocco earlier this month, driving more than 1,000 kilometers (621 miles) between the country's northern coast and the Sahara Desert in the south. “Morocco has a huge variety of landscapes and different surfaces in quite a short distance," says Bosman, adding that the car was tested “on every type of surface that a car like this could encounter." The road-legal car has a top speed of 145 kilometers (90 miles) per hour. On a sunny day, its battery range is around 710 kilometers (441 miles) on roads, and around 550 kilometers (342miles) off-road, depending on the surface. In cloudy conditions, the team estimates the range could be 50 kilometers less. Bosman noted that the vehicle had proved to be one-third more efficient than expected on the trip, and that its lightweight design made it less liable to get stuck on rugged terrain, and put less stress on its suspension.

TUE's automotive innovation lab has been experimenting with solar-powered vehicles for over a decade, producing concept cars that are typically "five to 10 years ahead of the market," says Bosman. A major challenge is turning the concept car into one that can be mass-produced. Alumni from the first TUE Solar program student team announced in 2022 that their company Lightyear was beginning production of a car fitted with solar panels.Earlier this year, the company filed for bankruptcy, before relaunching months later to focus on a new, cheaper model. Bosman and his peers hope their concept SUV could be mass produced in the near future. “We aim to also inspire not only everyday people, but also the automotive industry, the Ford and Chryslers of the world, to think again about their designs and to innovate faster than they currently do," says Bosman. "It's up to the market now, who have the resources and the power to make this change and the switch to more sustainable vehicles."
