Uses the nearest current DWD MOSMIX_L station forecast, or a station explicitly supplied by the caller. Global irradiance drives a transparent PV estimate and forecast wind speed drives a stated generic turbine curve; neither replaces a site-specific yield model. A constant hourly load and optional battery are simulated over 12 to 120 hours. The result is an installation-risk signal, not an official weather warning, emergency alert or guarantee of supply.
