Researchers have developed a smart water-spray cooling system for PV panels that activates only when temperatures exceed a set threshold, boosting efficiency while minimising water use in arid conditions. The system raised power output and reduced module temperatures, offering similar efficiency to continuous cooling but with far lower water consumption, pump operation, and costs.

The Chinese manufacturer said its new three residential battery lines support a depth of discharge of 90% and deliver over 6,000 cycles.

The inverters offer up to 99.2% efficiency, 200% PV oversizing, dual battery inputs, IP65 protection, and support for installations up to 144 kWh of storage capacity.

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.

A global study finds climate change will sharply increase high-temperature risks, accelerate degradation, and raise costs for rooftop PV, with economically disadvantaged regions hit hardest. Researchers warn current IEC standards underestimate future risks, urging urgent updates to avoid stranded assets and rising electricity costs.

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.

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.

South Korean researchers have developed a guided-learning framework that accurately predicts PV power without requiring irradiance sensors during operation, using routine meteorological data instead. The model reportedly showed strong out-of-sample performance while outperforming conventional irradiance-based approaches, particularly under noisy or inconsistent data conditions.
