M-Tec launches modular propane heat pump for residential, commercial use
The new residential heat pump system can be configured modularly and requires less than 150 grams of refrigerant, which allows it to be installed indoors. The system integrates with M-Tec’s energy management platform and supports multiple heat sources, photovoltaics, and battery storage.
Germany records growth in solar self-consumption
Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has developed a new way to quantify PV self-consumption in Germany using national register and grid-operator data, amid a steady rise in onsite use as installations and storage capacity expand.
Rescue bid for German solar glass maker GMB fails
The solar glass manufacturer started insolvency proceedings in July. An investor’s bid has now failed, leaving over 200 employees facing layoffs.
Austria deploys 1 GW of PV in January-September period
Austria added 1,036 MW of new solar capacity between January and September 2025, down from 1,419 MW over the same period in 2024, as political uncertainty, delayed legislation, and weakening residential demand strain the solar sector.
German developer commissions nation’s largest solar carport
Germany has brought a 17 MW photovoltaic carport online in Riedstadt, Hesse, spanning 76,000 square meters. It is expected to generate about 17 GWh per year, according to project developer Nawasol.
World’s largest foldable rooftop PV system comes online in Switzerland
A wastewater treatment plant in the canton of Bern has been inaugurated with what dhp Technology claims is the world’s largest foldable rooftop solar installation to date. The 3.6 MW array spans several treatment basins, allowing the existing site to serve dual purposes: wastewater treatment at ground level and solar power generation overhead.
Germany’s January-October solar additions reach 13 GW
The Federal Network Agency (Bundesnetzagentur) says Germany’s installation pace reflects shifting demand patterns between ground-mounted and rooftop PV systems.
Germany eases rules to accelerate battery heat and hydrogen storage
Germany is preparing to ease planning rules for battery, heat, and hydrogen storage systems built outside urban zones.
Switzerland forecasts 1.5 GW annual solar growth through 2027
Swissolar’s “Solar Monitor 2025” report projects annual PV additions of about 1.5 GW through 2027 and urges policymakers to sustain steady growth amid policy uncertainty and lower tariffs.
German network operators approve grid connection of 46 GWh of storage at medium voltage level
Last year, German network operators received 9,710 connection requests for battery storage systems planned for commissioning at the medium-voltage level. These requests correspond to a total of 400 GW/661 GWh. At the transmission network level, large-scale battery storage projects with a combined capacity of 51 GW have already been approved for development in the coming years.
