Elastocalorics have the potential to replace current air conditioning and heating systems, offering significant energy savings when paired with technologies such as photovoltaics.

A German research team is conducting practical tests to see how solar modules with integrated radio technology can be linked to form an overall network. The “communicative” panels should represent a simple and cost-effective solution for monitoring and controlling small-scale photovoltaic systems.

Germany-based Energielenker has developed a “self-learning” energy management system that controls energy flows in buildings with PV systems, using AI algorithms to analyze data from all relevant components.

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.
