Berlin solar mandate drives rooftop PV installations
Berlin’s mandate for solar installations on new and renovated roofs has spurred rapid rooftop expansion, but the German capital remains far from its 2035 clean energy goal.
Germany adds 1.95 GW of new solar in August
Germany installed 1.95 GW of solar in August, bringing total additions to 10.8 GW in the first eight months of 2025.
Floating PV system with ring-like floater geometry
Scientists in China have investigated the hydrodynamic performance of a novel modular floating photovoltaic system. They did so using a novel hybrid approach, which integrates viscous-flow effects from computational fluid dynamics into a potential-flow solver. They analyzed the new system with varying numbers of panels, either in a single chain or a parallel configuration.
Germany offers best European policy for agrivoltaics, claim researchers
Scientists in Canada studied romaine lettuce growth under cadmium telluride thin-film solar modules with varying transparency and photosynthetically active radiation, and found Germany’s regulatory framework most effective for maximizing agrivoltaic benefits.
Germany deploys 1.4 GW of solar in July
Germany added 8.65 GW of new photovoltaic capacity in the first seven months of this year, according to the Federal Network Agency (Bundesnetzagentur), bringing cumulative solar deployments to more than 109 GW.
