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.
Fothermo debuts immersion heater for excess PV power
The German company said its new device features a DC input supporting up to 3 kW of photovoltaic power. The heating output can be continuously adjusted between 0 W and 1,000 W. Priced at €549 ($635) including VAT, the heating element is designed for hot water storage tanks with capacities of up to 500 L.
Bosch starts up 2.5 MW hydrogen electrolyzer in Germany
German industrial group Bosch says the Bamberg facility complies with European Union renewable hydrogen rules and will produce over one ton of green hydrogen daily.
Eco Stor breaks ground on Germany’s largest battery storage project
Eco Stor says construction has begun on a 300 MW/714 MWh battery storage facility in Förderstedt, Saxony-Anhalt, now the largest such project under development in Germany.
Sonnen launches trade-in program for old solar battery storage systems regardless of condition or manufacturer
The initiative by the Allgäu-based company targets owners of photovoltaic storage systems installed before the end of 2020. The value of the trade-in bonus depends on the capacity of the new Sonnen battery. Sonnen describes the campaign as a “targeted growth initiative in a new market segment.”
Opes Solar Mobility starts VIPV module production
