Adelaide has an average of 7.6 hours of sunshine a day, so it makes sense to use it . This is a solar street light in Victoria Square in the City.
Electricity produced from these panels is sent to the State's electricity grid during the day, and the lights are powered from the grid at night. Each light produces about 100 kilowatt hours (kWh) more than it uses each year.
The lights are an initiative of the Adelaide Green City program which aims to develop Adelaide as a Solar City.
