Rooftop sunshine sets record after record across Australia

Australia's rooftop solar panels hit a new all-time high of 17,488 megawatts in the national grid at noon on Sunday — with solar supplying a record 72% of the grid's power at that moment. Victoria, South Australia and New South Wales each set their own rooftop records within the same five days, as ordinary households and businesses quietly become the country's biggest power station.
