Australia has the highest average solar radiation per square meter of any continent in the world. More than 2000000 households have solar system on their rooftop. The solar industry is rapidly increasing in Australia. PV panels are being used increasingly, both in the city and in remote locations, to produce electricity for households, schools, and communities, and to supply power for equipment such as telecommunication and water pumps. The majority of solar PV installations in Australia are grid-connected systems. Also, electricity for remote and regional Australian communities has been supplied by solar energy for many years. Australia is one of the sunniest countries in the world and there is huge potential for solar PV to make a significant contribution to electricity generation.
