UNSW Sunswift

The UNSW Solar Racing Team (also known as Sunswift after the name of their first race car) is the solar car racing team of the University of New South Wales in Sydney, Australia. The team currently holds a number of world records including the Guinness World Record for the fastest solar powered vehicle, and is best known for its participation in the World Solar Challenge (WSC). Since its founding in 1996 by Byron Kennedy, the Sunswift team has built a total of 5 different cars, the most recent of which is Sunswift V (also known as eVe).

The team primarily consists of undergraduate students from various disciplines including business, engineering and industrial design. Despite its team members being largely engaged in full-time study, Sunswift has remained competitive in all participated solar car challenges, earning prestige and recognition on the world stage as well as training young engineers to be on the cutting edge of their profession. A number of former Sunswift team members have moved on to establishing their own companies and others have attained highly sought-after positions in the workforce; for example, working as part of well-established racing teams such as those in Formula 1. Some of these team members remain in contact with Sunswift even after graduation, and act as mentors or advisors to 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 the public. In addition, Sunswift also visits schools in order to teach and inspire young children about implementing solar power technology whilst demonstrating how it can be a fun and effective method of powering a car.

All solar cars have at least 5 main parts to their power system: the solar array, maximum power point tracker (MPPT), battery, motor controller and electric motor. These cars rely on converting the electromagnetic energy of the sun into electrical energy, through the use of photovoltaic cells, and then converting that electrical energy into mechanical energy to drive the car, through the use of some form of electric motor. Maximum power point trackers act as an interface between the solar array and the battery, while motor controllers act as an interface between the battery and the electric motors.
