31 Institut Teknologi Sepuluh Nopember (Widya Wahana V)
The team from Institut Teknologi Sepuluh Nopember (ITS) produced their first solar car (Widya Wahana I) in 1985, with later cars in 1992, 1995, and 2013. That fourth car participated in the 2013 WSC Challenger class. This year, they are back, but in the Cruiser class. Their new car (Widya Wahana V, above) is currently on tour in Java and Bali (see below). Good luck, team 31!
Update: The video below shows the car being built, and the Java/Bali tour. Since then, the car has been repainted in the national colours of red and white.
