The Big Dish is a parabolic dish concentrator developed by the Australian National University's Solar Thermal Group. The initial prototype, SG3, was constructed on the Canberra campus of the Australian National University in 1994. A modified version of SG3 was exported to Ben-Gurion National Solar Energy Center at the Ben Gurion University in Israel. In 2006, a joint project led by the Solar Thermal Group with commercial partner Wizard Power, and funding from Australian's Government's Renewable Energy Development Initiative, began the design and construction of SG4. SG4 is located next to the SG3 dish, and was completed in 2009.
