The cost of solar photovoltaics (PV) electricity in Australia in 2030 is on track to be about A$30 per megawatt-hour (MWh). This conclusion arises from current trends in PV module efficiency and cost.

Importantly, $30/MWh is below the operational cost of most coal and gas fired power stations. Continued installs of rooftop and utility scale solar will likely lead to a wave of retirements of existing coal fired power stations during the 2020s. This price is also competitive with industrial gas heating.
