Using satellite data, Steadysat technology analyzes cloud cover and atmospheric conditions to provide reliable short-term solar energy forecasts.
Steadysat technology provides real-time solar irradiance and PV production forecasts up to 6 hours ahead.
By aggregating live data from 5 geostationary satellites from leading space agencies (NOAA, EUMETSAT, and JMA), our technology continuously monitors and analyzes key atmospheric parameters.
Steadysat perfectly complements Steadymet our advanced power model forecasting solution. Together, they offer a complete stack for both short-term satellite nowcasting and mid-range weather forecasts.
Steadysat is an indispensable technology for all actors seeking to maximize the value of their solar assets in an environment where reactivity and precision have become decisive competitive advantages.
