Battery energy storage went from strength to strength across Australia in Q4 2025, seeing the technology outperform past records in both the National Electricity Market and Western Australia’s Wholesale Electricity Market.

Around a fifth of solar panels examined in a new study fail much faster than expected and some may last for only half their anticipated lifetime.

A high voltage 2.5 MW / 3 MWh community battery installed through a South Australian electricity distributor, ARENA-funded program will be energised in March 2026 and remain on standby to help manage a regional community’s peak demand.

The Ariya demonstration vehicle features 3.8 m² of Lightyear’s custom solar panels integrated across the hood, roof, and tailgate. Testing showed that the car could generate 0.5 kWh of solar energy during a 2‑hour, 80 kilometer trip, delivering up to 3 kilometres of range at no extra cost or charging time.

South Korean researchers from Chungnam National University have developed a one-step, photoresist-free graphene patterning technique that results in very low electrical resistance and avoids damage, showing scalability in the fabrication of transparent, flexible electronics like solar cells.

Rooftop solar generation hit an all-time high in Q4 2025, up 8.7% with an output of 4,407 MW, while also reducing daytime operational demand, contributing to battery charging, and an overall new renewable energy generation record for the National Electricity Market of 51%.

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.

Australian manufacturer Siltrax will push forward with the commercialisation of its silicon-based hydrogen fuel cell technology after securing the tick of approval from international testing, inspection, and certification body TÜV Rheinland.

A new wireless, Wi-Fi-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 on the mid-north coast of New South Wales, significantly offsetting grid electricity use.

With silver prices rising, more large solar manufacturers are expected to switch to copper for cell metallization. Radovan Kopecek of ISC Konstanz tells pv magazine that he expects the entire industry to follow. Ning Song of the University of New South Wales says a small efficiency tradeoff may be acceptable if the cost savings are significant and do not introduce new reliability risks.
