Live data for solar resource assessment and real-time PV monitoring.
Compare the actual production of your plants with the output estimated by our real-time solution to continuously monitor your solar assets: detecting equipment failures, scheduling the cleaning of soiled panels, and optimizing maintenance.
Real-time data can also be used to fill gaps in measurement time series when in-situ sensors are unavailable or malfunctioning.
Our Steadysat technology processes real-time imagery from 5 geostationary meteorological satellites operated by NOAA (GOES-W, GOES-E), EUMETSAT (MSG-0°, MSG-IODC), and JMA (HIMAWARI). These satellites provide complete global coverage with high spatio-temporal resolution — delivering data every 5-15 minutes at spatial resolutions of 500m-2km, depending on region and channel (visible/infrared).
The satellite imagery provides continuous monitoring of cloud properties, including cloud type, opacity, and movement patterns essential for accurate solar irradiance forecasts.
In addition, our team enhances this satellite data by integrating meteorological models to deliver useful information on key atmospheric components that interact with solar radiation, such as atmospheric dust, ozone, and water vapor.
Our technology integrates multiple weather models that account for key atmospheric constituents affecting solar radiation:
These parameters are sourced from the Copernicus Atmosphere Monitoring Service (CAMS) global analysis and reanalysis provided by ECMWF, ensuring comprehensive atmospheric characterization.
The Global Horizontal Irradiance (GHI) in clear sky and cloudy conditions are computed independently using advanced models for Radiative Transfer, parallax correction and shadow projections.
Then, separation and transposition models determine the direct (beam), diffuse and plane-of-array irradiance (DNI, DHI, GTI).
For photovoltaic applications, our physical models integrate detailed plant specifications to deliver accurate power production estimates:
