A report by three renewable energy associations says expanding battery storage and grid flexibility could save €3.9 billion ($4.5 billion) per year through lower electricity system costs, reduced curtailment, and fewer periods of negative power prices.

A compact medium-voltage series regulator allows existing distribution grids to accommodate significantly more photovoltaic capacity by actively controlling voltage. The technology can be reportedly installed in existing transformer stations without additional construction, offering a faster alternative to traditional grid expansion.

A 44.5 MW solar plant paired with a 5 MW/10 MWh battery storage system has secured long-term power purchase and tolling agreements designed to optimize revenues while sharing an existing grid connection with wind and battery assets.

Global solar markets are entering another period of consolidation, with weaker demand, falling installations, and continued pressure on manufacturers, according to JinkoSolar's Frank Niendorf. Despite the downturn, the Chinese manufacturer is expanding its integrated energy solutions strategy, investing in storage, new module technologies, and long-term innovation.

Germany is planning to reduce funding limits under its BEG efficient buildings subsidy scheme, while introducing stronger income-based support and new eligibility rules for heat pumps. The proposed changes include lower eligible costs and a planned “Made in Europe” incentive for heat pump production.

Austria has inaugurated its first tracking agrivoltaic system designed to feed solar power directly into the railway grid. The 6.6 MW facility in Donnerskirchen combines renewable energy generation, organic farming, and biodiversity measures on the same site.

Switzerland's PV market added 1.33 GW of new capacity in 2025, bringing cumulative installations to 9.5 GW, while solar generation covered 13.71% of electricity demand.

Switzerland installed 1.33 GW of new PV capacity in 2025, down from 1.8 GW the previous year, while lithium-ion battery storage demand increased 70%, according to new figures from Swissolar.

Chinese inverter and energy storage manufacturer Sungrow will supply 125 MWh of battery energy storage systems (BESS) for two grid-supporting projects in Bavaria, Germany.

The Chaos Computer Club has identified a security vulnerability affecting photovoltaic installations that use Hoymiles inverters.
