Switzerland’s Phenogy has launched a megawatt-hour-scale sodium ion energy storage system at a commercial site near Bremen Airport in northern Germany. With this project, the Swiss manufacturer is making its debut on the European energy storage scene, backed by ambitions to develop fully vertically integrated local manufacturing.

A report by SolarPower Europe and Fraunhofer ISE finds EU-made solar modules cost €0.103 ($0.12)/W more than Chinese imports, but targeted policies could close the gap and help reach the EU’s 30 GW annual manufacturing target by 2030.

Swiss company Insolight inaugurated a 250 kW agrivoltaic installation on apple, pear, and apricot orchards in Conthey, producing 300 MWh per year for the grid, in collaboration with Agroscope, Romande Energie, and the canton of Valais.

Scientists in Germany report a method to boost performance of perovskite solar cells made with laminated carbon electrodes that are compatible with typical hole transport layers.

Thieves stole 50 km of cable worth about €100,000 ($117,400) from an 11 MW solar project in southern Germany, with repair costs expected to exceed the material loss, according to police.

REC led the US residential solar panel market in the first half of 2025, while Tesla lost share in home batteries and inverters amid supply and policy pressures, according to EnergySage.

World Green Energy signed a land sublease with Tata Steel Special Economic Zone Ltd for 50 acres in Odisha, India, to build a 2 GW tunnel oxide passivated contact (TOPCon) solar cell and 1.2 GW module factory.

Inox Solar has commissioned the initial 1.2 GW phase of its 3 GW solar module factory in India, advancing its plan for full-scale domestic production.
