Why choose CalibSun
High performance across all horizons
Reliable forecasts at all time scales (nowcast, hour ahead, day ahead, week ahead), thanks to an algorithm that intelligently weighs weather models, satellite imagery, and in-situ measurements.
100% Customizable
Parameterization and visualization of forecasts based on your data and business needs: frequency, time steps, aggregation...
Probabilistic forecasts
Confidence intervals for each forecast to model your scenarios and manage risk.
Green IT
Less energy-intensive than currently available solutions. Data processing is done by a single algorithm that operates without heavy and frequent learning phases, with seamless (continuous) processing based on "lazy learning."
API: Easy integration
Easy integration into all network management systems, including microgrids, and can be combined with all Energy Management Systems (EMS) to optimize PV management strategies.
Data privacy
The entire platform is secured via AWS, and the data from your sites is not used by third parties. Our algorithm only uses the data you own to generate your forecast.
