Cloudy skies have the potential to ruin the day for 10 Germans driving their solar-powered car almost the length of New Zealand.
The SolarWorld GT set off from Auckland War Memorial yesterday afternoon on the first leg of their trip to Hamilton alongside a battery-powered car built by a team from Waikato University.
The 10-person team from Germany's Bochum University of Applied Sciences plan to make the first trip around the world in a solar-powered car.
They started their journey in Australia where the SolarWorld GT competed in the World Solar Challenge from Darwin to Adelaide before it made its way to Sydney, where it was shipped to Auckland.
Dr Mike Duke of Waikato University said their journey got off to a rocky start with the dreaded Auckland traffic.
