SteadyMet
Solar forecasts for the coming days
ABOUT
Forecasts based on meteorological models for day-ahead solar forecasting needs
SteadyMet provides day-ahead solar forecasts up to the next 15 days. The product optimally combines several meteorological models and optimizes their output by leveraging measurement data from solar plants and by using artificial intelligence technologies.
Among the Numerical Weather Prediction (NWP) used by SteadyMet, it is worth highlighting the use of the Weather Research and Forecasting (WRF) model. It is a free regional meteorological model that can be configured at very high resolution, thus providing highly accurate forecasts at local levels.

KEY BENEFITS
WORLDWIDE COVERAGE
Thanks to the combination of numerical data from numerous weather services.
HIGH RESOLUTION
High temporal and spatial resolution thanks to the use of public local models.
TAILORED OUTPUT
In terms of update frequency, granularity and format.
MIX OF LEADING WEATHER MODELS
An approach combining predictions from the leading weather models, real time on-site measurements and cutting-edge technologies to offer accurate forecasts.
HIGH SPATIAL RESOLUTION IN REGIONS SUBJECT TO MICROCLIMATES
An in-house local high-resolution model allowing to provide a high spatial resolution forecast in areas where public local weather models are not available.
CUSTOMERS NEEDS
Our solutions are tailored to meet your solar business needs.
METHODOLOGY
Weather model’s outputs of interest (solar radiation, temperature, wind, etc.) are then optimized (step 3), by using production/irradiance observations, to take into account local phenomena, and by leveraging artificial intelligence technologies.
Ready-to-use forecasts, in a customized format, are then disseminated (step 4) through our proprietary web interface, csv files delivered via (S)FTP platforms or API.
