For years, the battery energy storage (BESS) story has followed a familiar script: costs fall, deployment accelerates, economics improve. Even when cell costs rose and system prices briefly flattened during the 2021-22 lithium price spike, the narrative largely held. Paola Perez Peña, senior principal analyst at S&P Global Energy, examines why the latest jump in lithium prices has only had limited impacts on overall BESS costs so far.

Rosi has raised more than €20 million in a Series B funding round to scale its photovoltaic module recycling business and build a new 10,000-tonne-per-year facility in Teruel, Spain. The company uses pyrolysis-based technology to recover high-purity materials including silver, silicon, copper, aluminium and glass from end-of-life solar modules.

Solar set a new generation record on Great Britain’s electricity grid during a week that also saw zero-carbon supply reach an all-time high. The new records come as the grid operator expands demand-side flexibility markets in anticipation of lower summer demand driven by strong solar irradiance.

Longi claims to have achieved the world’s highest efficiency for a silicon solar cell. The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).

The two companies announced a 60 GWh supply agreement on Monday, marking a pivotal step in the commercialization of sodium-ion battery technology.

The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency. The system improves light utilization by directing different wavelengths to optimized subcells.

The Chinese manufacturer said its TOPCon-compatible hybrid back-contact solar cell achieved a power conversion efficiency of 28.0%. The result was confirmed by Germany’s Institute for Solar Energy Research Hamelin (ISFH).

The U.S. Department of Commerce has issued preliminary anti-dumping determinations for three key solar-exporting nations, establishing duties of up to 123% on crystalline silicon photovoltaic cells and modules.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

The system integrates a battery, hybrid inverter, and home energy management system into a single device. It supports the integration of additional appliances, including heat pumps via SG-Ready interfaces. A connection to Tesla’s proprietary wallbox is also planned.
