Nuna II

Nuna II uses advanced space technology, provided to the team through ESA’s Technology Transfer Programme, enabling the car to reach a theoretical top speed of over 170 km/h.

The car’s shell is covered with the best triple-junction gallium arsenide solar cells, developed for satellites. The same cells are being tested on the SMART-1 satellite launched to the Moon on 28 September this year. Nuna II also carries Maximum Power Point Trackers, small devices that guarantee an optimal balance between power from the battery and the solar cells, even in less favourable situations like shade and cloud.After winning in 2001 with Nuna I, the Nuon Solar Team, from the Netherlands, will be bidding to retain their title.
