Weidmuller USA has launched the WM4 C PV Connectors, designed for residential, commercial, and utility-scale solar systems. The connectors support up to 1,500 V, feature crimp contacts, an anti-tampering lock, and IP67 protection.

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.

Turboden, part of Mitsubishi Heavy Industries, has energized what it calls the world’s largest steam-producing heat pump, delivering 12 MWth of superheated steam using low-grade waste heat and CO₂-free electricity with a coefficient of performance 10% above its guaranteed value of 2.

Scientists in Hungary found that ground-mounted PV modules at an intermediate elevation of 1.1 m achieve the highest efficiency and power output due to improved airflow and reduced cell temperature. Their study also estimated a levelized cost of electricity of $0.0843/kWh and 577.78 kg CO₂ mitigation over 25 years, while noting results are specific to concrete surfaces.

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 US 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.

An international research team used high-resolution electroluminescence imaging to quantify type-C cracks in 100 PV modules after 11 years of operation, linking crack distribution to real-world power loss. Concentrated cracks within individual cells were found to cause disproportionately high losses, highlighting the importance of cell-level crack analysis for effective PV maintenance.

An international research team has reviewed emerging solid-state and gas-cycle heat pumps capable of reaching temperatures of up to 1,600 K, assessing their challenges, applications, scalability, and technology readiness levels. The researchers say these systems could outperform conventional high-temperature heating technologies by achieving coefficients of performance above 1.

Japanese researchers used supercomputer simulations to reveal how sodium ions form clusters and move within hard carbon anodes, identifying nanopore sizes and transition regions that control diffusion and rate performance in sodium-ion batteries. Their findings offer design guidelines for optimizing hard-carbon anodes to improve energy density, cycling, and commercialization prospects.
