Young people from across Estonia collaborate with mentors, universities, and partners from both the public and private sectors. Together, they have already produced the Baltic region’s first, second, and third solar cars, which have competed in the world-renowned Bridgestone World Solar Challenge in Australia. Solaride is now entering its fourth season, during which the fourth solar car will be developed.
The journey is as important as the destination
Solaride’s mission goes beyond simply building a solar car. It’s about the journey itself. Through the program, students grow into skilled specialists, gaining invaluable practical experience before entering the workforce. A comprehensive training program combines the development of both technical and social skills. Participants can challenge themselves in five areas: engineering, marketing, finance, human resources, and training & development.
The project is open to young people from all over Estonia, with Solaride offices located at Tallinn University of Technology and Estonian University of Life Sciences in Tartu. More information about Solaride is available at solaride.ee.
Engineering and innovation at its finest
The engineering team is divided into mechanical, electronics, and software subteams, with a logistics team joining before competitions. The construction of the Solaride III Enefit car took place from early 2024 to spring 2025, built entirely from scratch by students. The car’s frame is made of steel, while its body features lightweight, durable carbon composite, developed by the students themselves.
A major point of pride is the student-designed battery pack, constructed using fiberglass to create a lightweight and efficient energy system. For the first time, the suspension box of the third car was made from carbon fiber, reducing weight while maintaining the necessary structural strength.
The ultimate challenge in Australia
The Bridgestone World Solar Challenge is a 3,000 kilometre race across Australia, from Darwin to Adelaide, completed over six days. The competition requires nine thirty minute mandatory stops, with the entire convoy following strict safety protocols.
The convoy operates as follows: first comes a scout car, warning of potential hazards and guiding the solar car to checkpoints. Next is the front chase car, which always leads the solar car and also signals dangers. The rear chase car monitors all data from the solar car and communicates instructions, including speed adjustments. Without both the front and rear cars, the solar car cannot safely continue. The convoy also includes a support van carrying all necessary tools and a trailer for transporting the solar car if needed. A media car operates independently to capture the best moments of the race.
In the 2025 race, the Solaride team achieved an impressive second place. For the first 2,000 km, they led the race, but weather conditions ultimately gave their competitors a narrow four minute advantage. Solaride started first thanks to a perfect score in the technical inspection, averaging 600 km per day at roughly 70 km/h.
The race was followed live on Delfi and the team’s journey is documented on YouTube.
Technology powered by the sun
The Solaride III Enefit can continuously travel at 50 km/h in sunny conditions using solar energy alone. The car’s roof features 4 m² of solar panels, it is rear-wheel drive, and is equipped with hub motors located directly in the wheels. The battery pack has a capacity of 15 kWh, while the motor delivers a maximum output of 3 kW, reaching a top speed of 120 km/h. Compared to Solaride II, the new car is 30% more efficient and accommodates two passengers.
The mission? First place and future changemakers from Estonia
Solaride’s mission extends far beyond building a solar car. The goal is to cultivate a new generation of young people capable of applying their knowledge in the real world and taking Estonian engineering and technology to the next level. The Solaride team shares a core attitude: we give a damn!
The project welcomes collaboration with mentors, companies, and partners who want to contribute to youth development or support the team financially. Together, we can create a future where solar energy drives not only cars but also ideas and innovation.
Support our journey. Help us drive the future, powered by the sun.
