The team beat the previous record 73 kilometres per hour (45 mph) – set in 1988 – with an average speed of 107 kilometres per hour (66 mph) over the 500-kilometre (310 mi) distance, which was done at the Australian Automotive Research Centre in Victoria. This record was not an exclusive Solar car record, but
375-403: The light intensity which can change rapidly if some cells become shaded. The electricity then flows into the battery where it can be stored for later use such as to drive the car while there is no sunlight. Although the battery is primarily charged by the solar panels, it can also be externally charged by the conventionally generated electricity at your home or workplace. The battery then discharges
400-419: The newer recruits, thus helping to continue the standard of excellence that has been embodied in the team since its founding in 1996. The Sunswift team also plays an active role in the local community by educating the general public about the advantages of solar versus conventionally powered vehicles. To this end, they regularly showcase the series of Sunswift cars at exhibitions and hold information days open to
425-466: The only road legal solar cars in the world and the first to adhere to the strict Australian Design Rules . As with eVe, IVy was built to compete in the World Solar Challenge , specifically for the 2009 race. However, unlike eVe, IVy raced as part of the Challenger Class and Challenger Class Silicon, ending up finishing 4th overall despite being the first silicon powered car across the line. Overall,

Mechanical problems caused a crash before the race, and the car completed the course unofficially. In 2006, the mechanics were improved. In January 2007, Jaycar Sunswift III broke the world transcontinental record, completing
500-474: The solar array, it transfers energy to the electrons within the photovoltaic cells, thus allowing them to conduct electricity and causing a current to flow. This current then travels to the MPPTs which alter the load across the solar array in order to ensure that it is generating electricity as efficiently as possible. The MPPTs have to constantly monitor the output of the photovoltaic cells because that output depends on
525-573: The team also designed it to resemble a modern-day sports car, rather than the typical space aged style of most other solar vehicles. The car was the fastest vehicle in the Cruiser Class, achieving Line Honours and overall third place for the Cruiser class while also attaining the highest top speed of 128 kilometres per hour (80 mph). On a single charge of its batteries, eVe can travel up to 500 kilometres (310 mi) or over 800 kilometres (500 mi) if powered by its own solar cells. Once fully depleted,
