Technology and R&D

Axinar has launched SolBox, a direct PV water heating system that powers electric resistance accumulators without thermal collectors. It’s designed for homes and businesses, offering real-time monitoring, MPPT optimization, and automatic grid backup.

Researchers from Australia’s national science agency are working with Malaysian authorities to assess how different battery chemistries perform under tropical conditions, including high temperatures, humidity, and corrosion, and how these factors affect durability, safety, and cost effectiveness.

Basquevolt and Bcare have successfully developed and integrated the first solid-state cells into a module for stationary applications, accomplishing this within the Iberdrola-led ASTRA-CC project (2023–2025).

Once considered isolated incidents, spontaneous glass breakages in solar modules are becoming more frequent, highlighting the limits of some manufacturing choices and the need for closer quality control.

The Italian company said the manganese-hydrogen battery it has developed represents an advanced solution for long-duration energy storage. The technology enables energy to be stored for many hours or even days, overcoming the structural limitations of lithium-ion batteries.

Sensors are an indispensable tool to inform utility managers of the state of the electricity grid and the occurrence of disruptions of any kind. The IEC provides the standards and conformity assessment that enable them to operate safely and efficiently.

A new generation of sodium-ion (Na-ion) battery cells has been launched as an alternative to the virtual monopoly of lithium-ion (Li-ion). Although the technology is unlikely to displace significant Li-ion market share, recent improvements make Na-ion a viable solution for certain niche applications, with potential for wider usage if cost becomes competitive.

An international research team has developed a new two-dimensional perovskite interlayer based on a co-crystal engineering strategy for more robust perovskite films. It demonstrated improved performance in small area perovskite solar cells and, in a 48 cm2 module, contributed to retain 95% of initial efficiency after 5,000 h.

The new IQ9N-3P microinverter utilizes gallium nitride technology to deliver 427 VA of peak power and 97.5% efficiency for the 480 V three-phase commercial market.

The SLDBatt project brings together TRL 7 battery technologies – including molten sodium‑salt, saltwater acid–base flow, and hydrogen–iron flow batteries – to deliver an innovative and cost-effective long-duration energy storage solution.
