Stella Terra collects solar energy using the solar panels on the roof. With these solar panels, and its robust construction, Stella Terra achieves complete independence in a sustainable manner, anywhere in the world. The solar car, which is road legal, has a top speed of 145 kilometers per hour, weighs only 1200 kilograms, and has a
range of 710 kilometers on a sunny day. On average, the off-road range is 550 kilometers depending on the type of surface.
A difficult challenge
Building a self-sustaining off-road vehicle presents new challenges. As far as known, it is the first of its kind worldwide. "Stella Terra must withstand the harsh conditions of off-roading while remaining efficient and light enough to be powered by the sun. That is why we had to design almost everything for Stella Terra ourselves, from the suspension to the converters for the solar panels," said Wisse Bos, team manager of Solar Team Eindhoven. According to Bos, Stella Terra is five to ten years ahead of the current market. "We are pushing the boundaries of technology. With Stella Terra, we want to demonstrate that the transition to a sustainable future offers reasons for optimism and encourages individuals and companies to accelerate the energy transition."
Morocco
Stella Terra has been tested extensively in Morocco. Starting from the north of Morocco, Stella Terra has driven over a thousand kilometers through various landscapes and terrains. “The efficiency of Stella Terra was hard to predict, meaning we were not sure whether we would make it on solar energy. While driving, we found that Stella Terra is 30% more efficient than expected. Therefore, we could complete the journey to the Sahara, all powered by the sun.” according to Bos.
A vision for the future
Mobility expert and professor at Eindhoven University of Technology, Maarten Steinbuch, is impressed by the team. "It is already difficult in normal conditions to build an energy-efficient car that can handle rough conditions, let alone to integrate solar panels into the car as well. I haven't seen anyone do that yet. I expect that in 5 to 10 years electric cars will be part of our entire energy grid system. And when the home battery makes its appearance, it will even be possible to generate energy via a solar car and deliver it back to your home. Solar Team Eindhovens innovations could change the future."
About Solar Team Eindhoven
Solar Team Eindhoven builds innovative, efficient cars powered by the sun. The team has previously won the World Solar Challenge in Australia four times in a row, competing in the family car class (Cruiser Class). With the Stellas, the team wants to demonstrate that the transition to a sustainable future offers reasons for optimism. And encourage individuals and companies to accelerate the energy transition.
