Twelve photovoltaic storage systems with capacities of 5 kW or 10 kW were included in the comparison, among them several new products, all of which achieved efficiency class A. A new study – also examining efficiency losses when storing electricity from the grid – highlights the importance of highly efficient battery storage. The researchers also took a closer look at the warranty conditions of the devices.

Solar Ireland told the Irish government that the Private Wires Bill’s proposed definition of private wires could bring rooftop solar installations within a full electricity licensing requirement, which would place significant additional demand on the energy regulator and slow down installations.

In a new weekly update for pv magazine, Solcast, a DNV company, reports that destabilized polar circulation in February produced wet and cloudy conditions in some parts of North America, while the central and eastern regions enjoyed elevated irradiance under clearer conditions.

This March, Women in Solar+ Europe (WiSEu) is launching its International Women’s Day 2026 campaign: “Beyond 10X: Leadership Without Double Standards.” Inspired by a reflection from Hungarian chess grandmaster Judit Polgár: “I had to prove myself 10 times more than if I’d been born as a boy”, the campaign invites professionals across the solar plus industries to reflect on how leadership is evaluated and how subtle double standards can shape career trajectories.

BP and Iberdrola say their 25 MW green hydrogen project in Spain is nearing commissioning, while Moeve has approved a final investment decision for a 300 MW project in Spain.

February marked an early 2026 turning point in France’s electricity market, with negative prices emerging for the first time, intraday volatility spiking, and battery energy storage systems (BESS) capturing growing revenue opportunities.

ACME Solar has signed two power purchase agreements (PPAs) totaling 450 MW under a firm, dispatchable renewable energy (FDRE) project with SJVN Ltd. It also commissioned an additional 38 MW/82 MWh at its Jaisalmer battery energy storage system (BESS) facility in Rajasthan.

Freight costs from the Far East to the U.S. and Europe have increased week-on-week, while almost 150 container ships currently unable to leave the Arabian Gulf due to the risk of sailing through an active conflict zone, according to analysis from ocean and freight rate benchmarking platform Xeneta.
