Australia’s rooftop solar fleet continues to expand with a combined 28.3 GW of generation capacity commissioned by the end of 2025 with approximately 4.3 million installations across the country.

Spanish building-integrated PV (BIPV) manufacturer Onyx Solar is delivering a custom building integrated PV system featuring almost 1,800 solar glass ‘louvres’ designed to help power Australian tech giant Atlassian’s new 39-storey headquarters in downtown Sydney with 100% renewable energy

Investment in utility-scale solar in Australia dropped 35% in the second half of 2025 compared to the previous six months with BloombergNEF (BNEF) saying the growth of rooftop solar and a booming battery market are among the reasons for the precipitous decline.

Renewable generation supplied more than half of Australia’s electricity in the fourth quarter of 2025, driving wholesale power prices down by nearly 50% and coinciding with record battery output, according to the Australian Energy Market Operator (AEMO). Coal-fired generation fell 4.6% year on year to a record quarterly low, while gas-fired output dropped 27% to its lowest level in 25 years.

UNSW researchers identified a new damp-heat degradation mechanism in TOPCon modules with laser-fired contacts, driven primarily by rear-side recombination and open-circuit voltage loss rather than series-resistance increase. The study highlights that magnesium in white EVA encapsulants accelerates degradation, guiding improved encapsulant and backsheet selection for more reliable modules in humid environments.

Nine generation and battery projects totaling 1.8 GW reached full output in Australia’s National Electricity Market (NEM) during the fourth quarter of 2025, according to the Australian Energy Market Operator.

Rooftop solar generation reached 4,407 MW in Australia’s National Electricity Market (NEM) in the fourth quarter of 2025, contributing to peak renewable supply of 78.6% and reducing daytime operational demand.

Engineers at the University of New South Wales have developed a real-time monitoring technique that reveals how silicon solar cells can self-repair following ultraviolet-induced damage, offering new insights into solar panel degradation and lifetime performance.

A new wireless, wifi-connected solar solution featuring three Sungrow 100 kW inverters is now allowing more than 300 kW of solar generation to be dynamically balanced across distribution boards throughout a school in Australia, significantly offsetting grid electricity use.

MyEnergy Engineering has completed an off grid 100 kW solar and 256 kWh battery system for a large-scale pig farm north of Adelaide, Australia.
