Possibility to do the impossible

At the end of 2021 despite the COVID-19 crisis, the first solar car constructed in the Baltics’ was built by Estonian students and tested in its first-ever race in Morocco Solar Challenge 2021.

During the second season (2022-2023) of Solaride, the next-generation car will be designed and built and is going to be tested at the Bridgestone World Solar Challenge in Australia in October 2023.

Solaride solar car uses 5x less energy than a normal car on the road.

The solar car is designed to drive from the north coast of Australia to the south coast with two charges covering a distance of 3000 km.

Before the final design, the solar car had ca 15 different conceptions.

It took us about 6 months and 10 000 work-hours to build a car. ~ 25 young engineers and a number of other team members from marketers to logistics contributed to the physical construction of the car.

Electronics

battery packs of 6 recycled Tesla battery modules
solar panel with an area of 4.82 m2 with 24% efficiency Maxeon elements
on the rear axle, two Marand 1.8 W electric motors
on-board electronics driven by self-developed printed circuit boards
self-developed ECU

Mechanics

carbon fiber body
carbon steel tubular frame
suspension: Double control arms/trailing arm
self-designed aluminum wheels
Bridgestone Ecopia 95/80R16 tires
carbon fiber seats weighing ~ 1 kg each

Software

a special software optimal speed calculator has been developed for the car, which takes into account the surrounding conditions and adds a driving range of approximately 7% to the car.
