Top Dutch Solar Racing will take pole position when the world's fastest solar cars leave Darwin to race 3,000 kilometres to Adelaide.
The 2019 World Solar Challenge starts from Darwin's State Square on Sunday morning, with the leading teams expected to glide across the finish within days.
Top Dutch Solar Racing earned the right to lead the field away with the fastest lap and a record time in qualifying at the Hidden Valley race circuit in Darwin on Saturday.

The team's Green Lightning car completed the lap in 1 minute 51.99 seconds, to shave two seconds of the previous best.
Sonnenwagen Aachen of Germany finished second, seven seconds behind with Japanese team Kogakuin about a second further back in third.
Defending champions, and still considered the race favourites, the Vattenfall Solar Team from the Netherlands finished in eighth spot, with a time almost 20 seconds off the pace.
But after a crash in trials earlier this week its NunaX car still posted a time four seconds faster than it managed four years ago.
Event Director Chris Selwood said Top Dutch Solar Racing had been rewarded for their exceptional teamwork and attention to detail.
'The team have clearly been diligent in their preparation and I expect to see them in the mix of this hotly contested field, with any number of teams capable of crossing the finish first in Adelaide," he said.
"However, it's not the start of this event, but the finish line that's the key and 3000 kilometres is a long way."
