A 200-pound vehicle, powered only by solar panels and a 3 kWh battery, crossed almost an entire continent. Hyperion, the Solis team car, covered 2,717 km of the 3,020 km World Solar Challenge 2025 from Darwin to Adelaide before an extreme storm put an end to the race. For the 23 students from Cluj and their teachers, the experience was more than a sporting performance: it was a real test of technical endurance, strategy and team spirit.

An endurance race with permanent challenges

The vehicle underwent rigorous pre-start checks and homologation, including safety tests and dynamic tests on the Hidden Valley circuit. On the first day, the team set off at 08:08 from Darwin, setting a cruising speed of about 110 km/h. After 496 km, Solis camped at Larrimah, alongside other international teams.

Days 2 and 3 confirmed the car’s stability and performance. With an average speed of 70 km/h, the Hyperion passed the halfway point, accumulating more than 1,600 km in total and finishing 15th in the Challenger category. Day 4 brought one of the most difficult challenges: an over-current failed the battery management system (BMS). The team stopped at the side of the road and in just 90 minutes identified and repaired the problem. Although it lost positions in the standings, Hyperion got back on the course and covered another 471km that day. “Every watt counts. That’s why reliability is as important as efficiency,” explains Raymond Nemeth.

In the following days, the team continued to run steadily, even though the weather changed drastically: cloudy skies, strong winds and low temperatures put the energy strategy to the test. The last day brought the toughest test: tornado code red and gusts of over 100 km/h. Just 20 km before Port Augusta, a combination of wind and aerodynamic currents from a truck knocked the vehicle off the road, damaging it. For safety reasons, the team decided to stop the race after 2,717 km.

Even so, the Hyperion crossed the finish line in Adelaide on its own two wheels, being displayed in Victoria Square and featured in the final parade. “Look you can do something with this green energy and even with solar panels you can cross an entire continent,” says Raymond.

Innovation on wheels

The Australian experience was an exercise in strategy and resilience. The team had to constantly adapt speed to the weather, deciding when to charge and when to conserve energy, planning every kilometer. Beyond the competition, the lessons learned – about managing limited resources, reacting quickly to crises and international collaboration – have direct value for the industry.

For students, it was an accelerated learning experience, impossible to replicate in a classroom. For companies, it is proof that Romania has talent capable of delivering performance even in the toughest conditions. The World Solar Challenge is more than a solar vehicle race: it’s a global showcase of innovation, where companies, universities and student teams from all over the world test their ideas.

Romania’s participation, through Solis, brings international visibility and confirms our ability to play in the big league of the energy transition. For the business environment, supporting such a team has clear benefits. For automotive or energy company leaders, it means association with technical excellence and global visibility. For professional communicators, it means inspirational stories, educational impact and alignment with sustainability goals.

Belgium 2026 next

If the Australian edition put the team through some extreme conditions, the next edition – scheduled for 2026 in Belgium – will bring a different kind of challenge. The European Solar Challenge has a different format: 24 hours of continuous competition on the circuit, where charging strategy, driver changes and the reliability of each module will be decisive.

For Solis, this will be an opportunity to capitalize on the experience gained in Australia, but also to test new solutions in a European context, closer to the Romanian business environment. Logistics will be more accessible, but the pressure to perform will be even greater as European teams compete directly for talent and innovation.

Over 30 organizations have already joined the Solis team. But the way forward depends on strengthening partnerships and continued support from industry.
