Solar Challenge Morocco 2021

5 days and 2500 km to test the Baltics first solar-powered car in extreme conditions

What is Solaride?

Solaride is an interdisciplinary educational project which started in 2020 through the students' initiative. Nearly 150 students and high school students from 13 Estonian educational institutions have participated during the first season.

Within the framework of the project, the first solar car in the Baltics was built by young people, which will be tested at the solar car competition in Morocco in October.

The competition will be followed by Solaride's new season (2022-2023), during which we will design and build the next generation solar car to take the podium in the World Solar Challenge in Australia in October 2023. It is a major event with a history of 35 years, watched by 15 million pairs of eyes worldwide.

Why we created Solaride?

Solaride is not just a car project. The "end product" of our program is not a solar car, but the hundreds of young people who, through their participation in the project, have gained a wide range of practical experience, skills and attitudes and built relationships that pave the way for doing great things on their own.

Quoting one of our first supporters, Martin Villig: "I support Solaride because this project inspires young people and grows the next top engineers, inventors and world-changers." In addition to providing students with valuable experience and skills during the project, participation in the competition will open the door to the world's top companies and universities for young people, and new start-ups are likely to emerge during the project.

Solaride's team is a great business card for Estonia and local higher education! At the same time, our activities help to popularize real-world specialties and sustainable and environmentally friendly thinking.

What is Solar Challenge?

The Solar Challenge Morocco is a race for solar cars, build according to the regulations. Solaride was supposed to take part in Bridgestone World Solar Challenge, but as a result of the Covid-19 pandemic, it was cancelled.

Student teams from several universities still wanted to test their built machines, and that's the way the Solar Challenge Morocco event was created.

The first Solar competition was held in 1982 as a challenge for home-built solar cars. In the years following, it has evolved into a number of different Solar events.

Cruiser class

Recognising the global imperatives of sustainable transport, the Cruiser Class was established in 2013 to encourage the creation of solar cars designed for practicality and acceptance in a given market segment. Cruiser Class teams aim to change the way we think about what we drive and what fuels we use. 

The winner of the Cruiser Class is determined by a number of factors as evaluated by our judges, including both performance and design. In 2017, the Cruiser Class winning vehicle carried an average of three people over 3,000 km using less 46 kWh of electricity—the energy cost of the journey was less than $4.70 per person.

Maximum length

I support Solaride because this project inspires young people and grows the following top engineers, inventors, entrepreneurs and world-changers.

Solaride is a bunch of progressive pioneers of the future who are building Estonia's first solar car to face the ultimate challenge to prove how successfully students can create innovation.

Support vechicle / Driver



5m long, 2m wide, 1.2m high

Unladen weight

~ 650kg
The unladen weight of the car is about 2 times less than the average car.

Load capacity

4x80kg (standardized in the competition)


Theoretically, the maximum speed is 140 km / h, but the solar car will start driving at a maximum of 90 km / h.

Engine power

The solar car is powered by two Marand electric motors inside the wheel. The power of one engine is 1.8 kW, ie the total power of the car is 3.6 kW.
The car consumes 5x less energy on the road than the average electric car.

Batteries and capacity

Six recycled Tesla battery modules. The battery capacity is 32 kWh. 

Driving range

The battery, together with solar energy, ensures a range of 1,200 km. It has not been tested, but we have based it on our designs.


To optimize energy consumption, software has been developed that takes into account the effects of external factors and maintains the most optimal driving speed according to the current conditions. This ensures a wider range. Increases efficiency by 7%.


The roof of the solar car is covered with 4.82 m2 of solar panels produced at the Solarstone factory. The panels consist of an average of about 20% more efficient single crystal solar cells, similar ones cannot be purchased “over-the-counter”.


To ensure good aerodynamics, the air resistance coefficient has been adjusted to 0.2 Cd (the 2009 Subaru Forester has an air resistance coefficient of 0.38 and the air resistance coefficient of Formula 1 cars is 0.7-1.1). The car is designed using the aerodynamics model in the form of an airplane wing cross-section. A "wind tunnel" has been created in the middle of the car, which helps to reduce the frontal area and, consequently, the air resistance. The car's air resistance is 30% lower than the average car.

Frame and suspension

The car body is a combination of an outer carbon-composite housing and an inner tubular frame. The tubular frame consists of steel produced by sustainable methods and the body panels are made of carbon fabric, which is also used in the production of aircraft.

Yesterday’s remarkable is today’s good and tomorrow’s mediocre. I admire a discipline whose energy is focused on breaking out of mediocrity. Solaride has taken on a difficult task. It is meaningful because genius grows out of difficulties.
