Retrieve solar radiation forecasting and historical data anywhere in the world through the Solcast Solar Data API service
The Solcast API in action. Retrieve solar radiation forecasting and estimated actuals data globally on demand, wherever you need it. Including instant validation against our 1-hour ahead forecast.
Solcast’s operates a global 3rd generation weather satellite cloud nowcasting system, which identifies, characterises and predicts cloud cover characteristics. Altogether, Solcast pulls in data from five weather satellites, updating our data live, every 5-15 minutes, at high-resolutions (1-2km). This tremendous amount of data (billions of data points each day) pass through our proprietary solar radiation and PV power conversion model to deliver a variety of data products focused on PV power output and solar irradiance data through a clearly documented and fully-supported API framework.
