Three Fraunhofer institutes in Germany have developed a tandem module for direct hydrogen production, as a modular, flexible alternative to large electrolyzers. PV is an additional power supply.

The move follows failed efforts at Intersolar to find an investor or buyer. The manufacturer of micro inverters filed for insolvency right at the end of the trade fair.

Large battery storage systems are taking on an increasing number of tasks in the German grid, meaning that the volume and speed of transactions can no longer be managed without computers. As a result, traders are working on algorithms to fully automate transactions.

The device can be connected directly to a solar generator without an inverter and can control heating elements or electric boilers.

Greentech has started operating 103 MW of ground-mounted solar capacity in Germany.

Enpal and Entrix aim to build Europe’s largest virtual power plant (VPP) via their new Flexa joint venture. They plan to integrate PV systems and other decentralized energy producers and consumers into a multi-gigawatt network with an AI-powered electricity trading platform.

Solarwatt says it has developed a DC version of its Battery flex PV storage system. The new version offers backup power and is optimized for the Steca SolBrid hybrid inverter.

A recent report from the Swiss Federal Council describes the difficult trajectory of efforts to rebuild the domestic PV industry and concludes that plans to create a European supply chain could be too expensive.

Fronius has revealed plans to cut 350 jobs due to “persistently weak sales” from its solar energy division. The Austrian inverter manufacturer significantly expanded production and hired new employees in 2022 and 2023.

Rabot Charge’s monthly analysis shows significantly more hours with negative prices on the Germany electricity market than in April. However, the average price in daily transactions was €6.72 ($7.32)/kWh – higher than in the previous month.
