Actual and forecast solar power and irradiance data, globally, using satellites and surface measurements

Actual and forecast solar power and irradiance data, globally, using satellites and surface measurements.

Solar power is becoming increasingly important in the energy markets, however the variable nature of solar generation poses significant challenges for integration into the electricity industry.

Weatherzone, in partnership with Solcast, now provides solar power forecasting and solar irradiance data, for both large-scale solar farms and small-scale PV systems, plus their grid or regional aggregates.

Grid Aggregations

Improve load forecasts
Balance supply and demand
Manage and plan your network
Control virtual power plants and microgrids

Tens, thousands or millions of PV systems, simulated and forecasted in real time, rolled up into your grid or market region.

Utility Scale Forecasts

Reduce penalties & curtailment
Plan maintenance
Manage attached storage
Get high quality historical irradiance data
Group systems for grid management
Get started fast with simplified data requirements
Upload data to improve your forecasts

Rooftop PV Forecasts

Actively manage storage, VPPs and smart devices using tuned PV output forecasts
Access forecasts for each site using our API
