Fast ramps
Passing cloud fronts drop output 40% in minutes.
Solutions
Solar Forecasting
Nowcast irradiance and PV output, minutes to days ahead.
Overview
Sub-hourly solar forecasts powered by orbital irradiance
BioSky tracks cloud fronts and irradiance from space to forecast PV generation across rooftops, farms and feeders, ahead of every ramp.
The challenge
Clouds break solar plans
Distributed PV
Rooftop solar is invisible to most grid operators.
Penalty exposure
Unscheduled swings trigger DSM and balancing costs.
How it works
Three inputs, one forecast
Cloud tracking
Geostationary and LEO imagery resolves cloud motion.
Irradiance models
Clear-sky and aerosol modelling per location.
Deep learning
Nowcasting networks trained on local PV output.
Key features
What the model does
Nowcasts irradiance from 5 minutes to 72 hours
Maps distributed rooftop solar from imagery
Re-forecasts on each satellite pass
Captures cloud-front ramp events early
Probabilistic ranges for risk-aware scheduling
Signals to traders, DISCOMs and control rooms
