International and local solar car teams are getting ready to battle it out on South African roads as they prepare for the 2018 Sasol Solar Challenge.
The teams were announced at the event’s launch held at The Maslow Time Square in Pretoria on Thursday, 19 July 2018.
Some of the world’s top teams are attending this year’s event including current world champions Nuon
from Delft University in The Netherlands and former world champions Tokai University from Japan.
New participants in this year’s event include teams representing City University of Hong Kong from
China, Manipal University from India, and the Solar Energy Racers from Switzerland.
The South African teams are the Tshwane University of Technology, North West University, and
newcomers Seilatsatsi from the Central University of Technology and Sonke Siyakude – a combined
team from St Alban’s College and St Augustine’s LEAP School. South Africa is one of only a few
countries where high school teams compete against university students.
The 2018 event marks a decade of solar car challenges in South Africa, as it runs for the sixth time. The
teams will set off from Pretoria on 22 September and finish in Stellenbosch on 29 September. The
awards ceremony takes place in Cape Town on 30 September.
The epic 2 500 km event tests the limits of energy, innovation and technology as teams are challenged
by diverse conditions. Baking sun, violent storms, high winds, changing road surfaces and a drop-in
altitude of nearly 2 000 metres have to be taken into account by team strategists who work out their
vehicles’ power consumption. Teams travel with entire weather stations of their own and strategists who
make make-or-break decisions as conditions change, which is what makes the Sasol Solar Challenge
one of the toughest of its kind.
Taking advantage of loops in the route that teams are allowed to repeat as many times as they’re able
to, top teams will clock close to 5 000 km during the eight days.
Dutch team Nuon won the event in 2016 with a record-breaking 4 716 km and are returning to defend
their title. The regulations for this year’s event have changed, making it tougher for teams to achieve the
same distances that they did in 2016. Cars are only allowed to have solar arrays of 4 m², where
previously their arrays could be 6 m². This puts significant pressure on the engineers to deliver the
power from a smaller array. To do this, teams reduce the weight of their cars, and improve the energy
technology. North West University, the top South African team in 2016, aims to match or better their
result. They placed fourth, completing 3 524 km.
At the launch, Sasol Solar Challenge director and founder Winstone Jordaan highlighted the importance
of the advances made in technology as a direct result of such events.
“The Sasol Solar Challenge inspires students to develop new technologies by creating a competitive
environment. They contribute to core research on solar technology, including the manufacturing of solar
cells, their casing, converters, controllers and electronics. The research done by solar teams has
become invaluable to the energy industry.”
Jordaan added that the Sasol Solar Challenge was a way of bringing these top-notch technologies into
communities throughout South Africa, making it more accessible and serving as a practical
demonstration of their capabilities.
Sasol has sponsored the solar challenge since 2012 as part of its commitment to furthering science,
technology, engineering and maths education and inspiring learners to pursue technical careers.
“Everybody involved in the Sasol Solar Challenge is at the top of their game and aiming for constant
innovation as they test ideas and technology in tough real-world conditions,” said Elton Fortuin, Sasol’s
Vice President of Group Communication and Brand Management. “This is the commitment and skill and
energy which we recognise at Sasol, and which South Africa needs to reach its industrial and energy
Sun International are proud supporters of the 2018 Sasol Solar Challenge and are providing assistance

These statements may also relate to our future prospects, developments and business strategies. Examples of such forward-looking statements include, but are not limited to, statements regarding exchange rate fluctuations, volume growth, increases in market share, total shareholder return, executing our growth projects (including LCCP), oil and gas reserves and cost reductions, including in connection with our BPEP, RP and our business performance outlook. Words such as “believe”, “anticipate”, “expect”, “intend”, “seek”, “will”, “plan”, “could”, “may”, “endeavour”, “target”, “forecast” and “project” and similar expressions are intended to identify such forward-looking statements, but are not the exclusive means of identifying such statements. By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and there are risks that the predictions, forecasts, projections and other forward-looking statements will not be achieved. If one or more of these risks materialise, or should underlying assumptions prove incorrect, our actual results may differ materially from those anticipated. You should understand that a number of important factors could cause actual results to differ materially from the plans, objectives, expectations, estimates and intentions expressed in such forward-looking statements. These factors are discussed more fully in our most recent annual report on Form 20-F filed on 28 August 2017 and in other filings with the United States Securities and Exchange Commission.
