Data confidence level:
This FACT indicates the percentage of households that have a solar power system installed in each Australian city. Solar energy technologies include solar heating, solar photovoltaics, solar thermal electricity and solar architecture, which can make considerable contributions to solving some of the most urgent problems the world now faces.
Solar technologies are broadly characterized as either passive solar or active solar, depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orientating a building to the sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. For this indicator, only active solar techniques were considered.
The city with the highest percentage of solar power users is Perth, at 29.1 percent. The city with the least is Hobart at 10.4 percent.
