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.

There was a watershed moment for Australian energy transition this week as the Australian Energy Market Operator released its energy dynamics report for the December quarter of 2025: Renewables comprised more than half of energy supply in the quarter, driving down wholesale electricity prices by nearly half. Coal-fired generation was down 4.6% year on year, falling to an all-time quarterly low. Gas-fired generation plunged 27% to its lowest level for 25 years.

For the last decade, the global conversation around electric vehicles (EVs) has focused almost entirely on adoption. Targets, incentives, charging stations and sales figures have dominated headlines. The EV transition is happening daily, at street level, across the Asia-Pacific region and beyond. Yet a far less glamorous question is now becoming just as important as how many EVs we sell: what happens when their batteries are no longer good enough for the road?

Solar and wind now provide 99% of new generating capacity in Australia. Renewables supply more than 40% of power to the main grid. Australia will need six times as much solar and wind to reach net zero through the electrification of everything. This means building new transmission corridors, as existing lines were built to connect cities with coal power stations. But the best solar and wind resources lie in different places.

Australia has led the charge in solar energy, setting the standard for solar panel adoption worldwide. The Snapshot of Global PV Markets 2024 report published by the International Energy Agency Photovoltaic Power Systems Programme shows that more than 30% of Australia’s households are fitted with rooftop solar PV units, harnessing the sun’s power to meet their energy needs.

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.

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.

Space-based solar could power AI more efficiently than on Earth, with full-scale deployment possible in two to three years, Elon Musk says SpaceX’s Starship launch vehicle and its reusable rockets aim to sharply reduce space access costs, enabling solar-powered AI satellites and potentially large-scale extraterrestrial energy infrastructure.

Plans for a 250 MW solar and 350 MWh battery energy storage project proposed for Queensland’s Western Downs region are now available for public comment as developer Pacific Partnerships seeks a green tick from the federal government.

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.

The Chinese firm has unveiled its latest energy storage solution, the ENERpro-LFP48300, equipped with a 48V, 300 Ah lithium battery. The company boasts a lifespan of more than 9,500 cycles at a high 95% depth of discharge.

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.

Chinese manufacturer Sungrow has introduced a new utility string inverter, a three-phase hybrid inverter for commercial and industrial applications, and a liquid-cooled energy storage system.

Next-generation solar innovator Halocell Energy is set to benefit from the development of a sovereign supply chain for high-purity precursors to perovskite after signing a memorandum of understanding with Queensland advanced materials company Lava Blue.

China-based PV equipment supplier Ideal Energy Sunflower Semiconductor has completed an AI-enabled pilot line for ultra-thin, flexible heterojunction solar cells, targeting lightweight power systems for space and near-space applications.

South Australia-based renewables developer Green Gold Energy says it has received connection approval for a 108 MW solar farm and 440 MWh battery energy storage system being developed in the state’s northeast.

Researchers have used multivalent amidinium ligands to boost perovskite solar cell efficiency to 25.4%, achieving over 95% stability after 1,100 hours at 85 C. The proposed approach enables controlled low-dimensional passivation layers, offering a practical route for durable, large-area perovskite devices.

Researchers at the University of New South Wales have achieved a record-setting power conversion efficiency with solar cells made from antimony chalcogenide, an emerging PV material regarded as a strong candidate for next-generation solar technology.

Researchers in China developed a novel two dimensional seeding agent to regulate crystallisation in a 1.80-eV wide-bandgap perovskite film. A perovskite-silicon tandem device made with the resulting optimised subcell achieved an efficiency of 31.13%, outperforming a control device.

University of New South Wales researchers found that some POE encapsulants can trigger severe corrosion in TOPCon solar modules, causing up to 55% power loss under damp-heat conditions. Their study highlights that module reliability depends on the exact encapsulant formulation, not just the polymer type.

The launch of the new product suggests United States-based manufacturer Tesla could renew its focus on residential solar and expand lease options with its Powerwall residential battery energy storage offering.
