This edition of the 3000 km of Sun Race in Australia from Darwin to Adelaide has had the same teams in the Challenger class since the start of the same teams. Each has a 6 m2 sun deck, but no two are exactly the same.
The newest 3,000 km Bridgestone World Solar Challenge in Australia from Darwin to Adelaide is planned until 31 August 2025. At the end of the fourth day, the top three teams in the Challenger Class are for since early in the competition, As a sister publication PV Magazine Australia has reported. According to the most recent checkpoint, there was less than 10 minutes separated The newest shipping.
The top three teams so far are Brunel Solar Team from the Netherlands, Belgium Solar Racing Team Innoptus and Solar Team Twente, also from the Netherlands.
The event is held for the first time in the winter. The Challenger class is a single passenger vehicle with at least three wheels and a maximum of 6 m2 of solar collector area.
The Brunel team has 18 members of the Delft University of Technology, who participate in the Nuna 13 Racer. His spokesperson confirmed PV -Magazine That the sun deck has supplied 350 back contact cells by the Chinese module manufacturer Aiko. It also has a new removable “swordfin” that depends on wind conditions.
The Innoptus Solar team at the University of Leuven, which won the previous two editions of the race, controls infinite Apollo. The solar partner This year is the Chinese vertically integrated solar manufacturer Longi. The spokesperson confirmed that Longi supplied 27%-efficient back contact cells, as well as support for the photovoltaic (VIPV) solution integrated by the vehicle.
It has previously used a fin for stability and this year it went one step further with a double fin design. The asymmetrical fins are intended to be able to handle a wider range of wind corners, according to the team spokesperson.
“Racing cars on solar energy are the ultimate test for PV technology,” said Wout Rubbrecht, the Innoptus Solar team leader in an earlier explanation about the collaboration. “Racing cars must maintain efficient power generation under conditions of vibrations with high intensity, extreme temperature differences and curved body shapes.”
Zonneteam Twente, with 17 members of the University of Twente, Saxion University of Applied Sciences and ROC van Twente, competes with the latest car, Red Discover. It has no fin. It uses high -quality back contact solar cells supplied by Aiko, who provide superior efficiency and capture more light “with fewer losses”, according to a press release.
The fastest qualification vehicle of the 2025 edition was the Covestro Aethon of Sonnenwagen Aachen, a student team of RWTH Aachen University and and FH Aachen in Germany. It is in fourth place, according to the last check-in.
His spokesperson said PV -Magazine That PV specialist in the Netherlands Mito Solar produced the solar array based on monocrystalline back contact silicon solar cells and tandem perovskiet-silicon solar cells. The tandem devices, supplied by the British startup Oxford PV, are embedded at the back of the deck while the others are attached to the front.
