Australia's installed cost of utility-scale solar has not fallen at the pace required to reach the country's “ultra-low-cost solar” (UCLS) ambitions, despite continued progress in cell and module efficiency.
Australia's National Electricity Market (NEM) recorded a combined 2,413GWh of solar generation in June 2026, comprising 1,092GWh from utility-scale assets and 1,321GWh from rooftop systems.
