As zero-emission cars continue to gain popularity, the challenge of limited charging infrastructure still hampers the widespread adoption of electric vehicles. Stella Terra, a groundbreaking khaki-green SUV, could change the game by harnessing solar power to drive long distances and navigate remote areas where traditional energy sources and well-developed roads are scarce.
Crafted by a team of students at Eindhoven University of Technology (TUE), Stella Terra proudly claims the title of “the world’s first off-road solar-powered vehicle.” According to Thieme Bosman, events manager for the team, this innovative creation has the potential to facilitate emergency aid, deliveries, and transportation in regions with underdeveloped infrastructure.
Recently, the vehicle faced rigorous testing in Morocco, covering more than 1,000 kilometers (621 miles) from the country’s northern coast to the Sahara Desert in the south. “Morocco has a huge variety of landscapes and different surfaces in quite a short distance,” Bosman noted, highlighting that the car demonstrated its capabilities on every type of terrain encountered during the expedition.
This road-legal solar-powered SUV boasts a top speed of 145 kilometers (90 miles) per hour. On a sunny day, it can achieve an impressive battery range of approximately 710 kilometers (441 miles) on roads and around 550 kilometers (342 miles) off-road, depending on the surface. In cloudy conditions, the range may be slightly reduced, estimated at 50 kilometers less.
The vehicle exceeded expectations during testing, proving to be one-third more efficient than anticipated. Its lightweight design not only reduces the risk of getting stuck on rugged terrain but also places less stress on the suspension.
Compared to standard electric SUVs, Stella Terra is significantly lighter, weighing around 25% less than the average mid-sized SUV at just 2,645 pounds (1,200 kilograms). Its aerodynamic design reduces drag, and the utilization of lightweight and robust composite materials further contributes to its efficiency.
Bob van Ginkel, the technical manager for Stella Terra, emphasizes the advantage of the solar panels on top, stating, “we can have a much smaller battery because we are charging while driving.” This liberates drivers to explore off-road locations without the need for charging points, providing the freedom to roam without constraints.
The vehicle’s versatility extends beyond travel, with elements designed to make long-distance journeys comfortable. The car’s seats fully recline to create a bed, and when stationary, the solar panels can be extended to maximize charging while doubling as an awning for shade.
Innovations within Stella Terra include highly efficient solar panel converters that hold promise for the broader solar industry. As solar power continues to play a pivotal role in sustainable transportation, Stella Terra represents a remarkable leap forward in renewable energy and off-road exploration.
