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.

Scientists in Hungary found that ground-mounted solar modules at an intermediate elevation of 1.1 metres achieve the highest efficiency and power output due to improved airflow and reduced cell temperature.

Perth-headquartered energy storage and battery-based power systems specialist Magellan Power has teamed with specialist investment manager Viburnum Funds to boost its manufacturing capabilities and fund expansion in Australia and internationally.

The United States company said its Power Control software is designed to help installers reduce costs and streamline interconnection. Among its features is the ability to control aggregate system exports through software-based limits.

The Chinese manufacturer said its 15 kW three-phase low-voltage hybrid inverter is paired with the stackable BP5000 5 kWh battery supporting up to 120 kWh. It features three MPPTs, 150% oversized PV input, and smart load management for optimised self-consumption.

High-resistivity silicon wafers offer superior efficiency potential but are highly sensitive to edge recombination and mechanical damage, limiting their commercial use compared to more robust standard wafers. Researchers from Longi and Sun Yat-sen University demonstrated that integrating in-situ edge passivation unlocks this potential, significantly boosting back-contact solar cell fill factor and efficiency.

The latest report from the International Energy Agency’s Photovoltaic Power Systems Programme says second-life PV modules have the potential to reduce waste and extend the value of solar assets, but their market today remains underdeveloped and requires advances in technical qualifications, scalable reuse infrastructure and supportive policy frameworks.

The Portuguese company said its new Drone AgroPV Cleaning Agent is scheduled for release in June. It has a safe formulation for crops and soil.

Queensland based critical minerals company Graphinex is collaborating with Japanese entities to deliver graphite from its proposed $1.3 billion Esmeralda mine project to Japan, and create a fully integrated graphite-to-anode supply chain.

Italian inverter manufacturer Fimer has launched a new advanced photovoltaic array sizing simulation tool that combines real site data with customer behaviour accessed through its cloud-based project management platform Aurora Vision.
