Imagine a revolutionary solar car, equipped with an ultra-light carbon fibre monocoque, a custom battery pack, ultra-efficient electrical circuits redefining the standards of energy efficiency, and a genetic algorithm that allows us to defy the elements and adapt to the whims of the weather. The result? An exceptional vehicle capable of travelling thousands of kilometres, powered only by the sun, and worthy of a Quebec license plate.

We are a team with varied talents, committed to every step of the project. Each member contributes to accelerating our race towards sustainability. Thanks to the support of our partners, we are not just a team; together, we become pioneers in the shift towards renewable energies.

The Bridgestone World Solar Challenge is the crème de la crème of international competitions. A 3000 km rally in Australia, on public roads, where we must overcome the most extreme conditions: wind, sand, and the scorching temperatures of the desert.

3000 km

After proving the reliability of our vehicle on a closed circuit at the Formula Sun Grand Prix, we embark the American Solar Challenge, a rally on open roads, travelling 2800 km across the USA.

Born out of the challenges of the 2020 pandemic, Eclipse 11 highlights the resilience and innovation of the ÉTS Solar Car Team.

Unveiled in February 2023 and crafted throughout 2022, this sleek vehicle is gearing up for its first race at the Bridgestone World Solar Challenge in October. Lightweight and efficient, Eclipse 11 aims to set new records and continue ÉTS's legacy in solar racing.

2018

Designed in 2017 and manufactured in 2018, the Eclipse team created a catamaran-style vehicle with a carbon fiber monocoque.

Eclipse 10's first competition was at the 2018 American Solar Challenge. The team ranked in 3rd place.

In 2019 at the Bridgestone World Solar Challenge, Eclipse 10 was the first Canadian solar vehicle to finish the rally. The team ranked as 1st Canadian team, 2nd North American team and 9th overall.

After participating in numerous visits to various trade fairs and events, the last time Eclipse 10 participated in competition was at the American Solar Challenge in 2022 to train the next generation of the team to face new challenges.

2016

The design of Eclipse 9 marks a return to basics for the ÉTS team. After the hard financial and logistical ordeal that was Eclipse 8, the birth of a new prototype was the key to putting the project back on the path to success. The car was designed by combining the ultra-safe regulations of the ASC with the more modern regulations of the WSC.

The team was therefore forced to make a vehicle with 4 wheels and a length of 4.5 meters which can accommodate a driver in a seated position. It is thanks to the participation of important partners that the Eclipse 9 team managed to make a light and efficient vehicle while learning a lot about the foundations of solar car design.

8th at ASC 2016, 4th at FSGP 2017 and Sportsmanship Award at FSGP 2017 due to the team's positive and competitive attitude throughout the event.

ECLIPSE VIII

2013

The Eclipse 8 team has been faced with all kinds of challenges during its journey which has led it to participate in two major competitions on two different continents in less than 8 months.

Faced with very strict schedule and budget constraints, the team opted for an extraordinary design with a tubular steel frame that completely encloses the driver. The prototype could then easily be modified for subsequent use during the American Solar Challenge 2014, compared to a prototype of a composite monocoque design.

Eclipse 8 therefore participated in the 2013 World Solar Challenge and obtained the best result in the history of ÉTS in this competition, despite engine problems that limited its cruising speed to approximately 55 km/h. 18th at the 2013 WSC and 9th at the 2014 ASC.

2011

The Eclipse 7 car had three wheels and reached a top speed of 107 km/h. It was made of vacuum-molded carbon fiber. Its in-wheel motor, located behind the driver, was a team manufacture, a brushless, three-phase AC synchronous motor with Csiro magnets. It was connected to a Tritium motor controller and was powered by 40 kg of LiFePo4 batteries which offered a maximum discharge current of 420 amps. In order to recharge the battery, Eclipse 7 relied on 403 solar cells made of silicon and built by the company Sunpower.

Eclipse 7 was a very good car. That said, her weight (too heavy at 285 kg) meant that she could hardly compete with the top teams. In addition, the extreme weather conditions (intense fires and winds) came as quite a surprise to the team. As a result, at the 2011 World Solar Challenge competition in Australia, the team finished 27th out of a total of 35 teams.

2009

Following the Eclipse 5 car, the members of Eclipse completed their studies and very few experienced alumni remained in the team. So, a new team was created, without a lot of experience, but with a lot of motivation! We knew that the design of Eclipse 5 had been optimized a lot, to the point of being difficult to manufacture. So, the design of Eclipse 6 practically started from a blank sheet, hence the 4-year delay for the manufacture of the car. The mechanical design of the car had to be easier to manufacture, not a breathtaking design, but was robust enough to cover the long distances of a competition.

The Eclipse VI team participated in the World Solar Challenge 2009 competition. Due to a design problem of the MPPT circuit (Maximum Power Point Tracker, Solar panel power optimization circuit), it was impossible for us to recharge our batteries. This earned us a very bad position in the standings. We were only able to ride at the start of the race and once again in the middle of the race. This issue was fixed by the Eclipse 6 team members upon returning from Australia. A new circuit has been designed, documented and successfully used by the Eclipse 7 team. 24th position in the 2009 World Solar Challenge competition.
