An Australian research team has developed a five-step, rule-based method that detects and classifies underperformance in PV systems using only AC-side inverter data. Validated across more than 1,000 systems, the approach offers a low-cost, low-intervention solution for improving reliability, fault response, and PV system performance.

A four-year study found that overhead solar panels in a Victorian pear orchard reduced sun and hail damage but decreased fruit yield and blush colouration. While energy production and tree stress resilience improved, the findings highlight trade-offs for agrivoltaic systems, with potential applicability to other fruit crops like apples and cherries.

RMIT University researchers have opened the door of possibility for self-powered sensors on roads and other electronic devices by generating piezoelectricity using a flexible nylon-film device.

New research shows how agrivoltaic systems can reshape soil by altering moisture, temperature, and microbial activity, creating heterogeneous zones under and between panels. Proper design and management can boost soil health and crop resilience, especially in degraded or arid regions, though long-term effects remain uncertain.

UNSW researchers have developed a thermal-aware tracking algorithm that reduces solar module temperatures and UV exposure during inverter clipping and curtailment, slowing degradation without lowering AC output. Tested in Chile’s Atacama Desert, the strategy was found to lower module temperatures by up to 7.7 C.

Norwegian fire safety specialist Bridgehill has developed a fire-resistant roofing membrane designed for use beneath rooftop PV systems. The company says the product is intended to limit heat transfer and flame spread in commercial and industrial installations subject to strict fire safety and insurance requirements.

Real-world testing of an artifical intelligence-enabled energy management system and virtual power plant technology is underway in Dubbo, through a TRaCE funded collaboration between the University of New South Wales, Sungrow and Dubbo Regional Council.

South Australian clean energy technology recycling developer Iondrive has reported early laboratory results from its proprietary IONSolv metal extraction platform shown greater than 85% silver extraction efficiency in initial bench-scale testing.

Researchers at NREL found that UV exposure can cause significant, partly non-recoverable degradation in TOPCon solar cells, with strong cell-to-cell and intra-cell variability linked to passivation and processing inconsistencies. While some UV-related losses recover quickly under light and are unlikely to affect field performance, the findings highlight gaps in current qualification tests and the need for improved UV aging standards.

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.
