Real clouds, real data. Designed specifically for solar energy applications.
Real time and forecast irradiance data and PV power data based on 3 dimensional cloud modelling. Powered by live satellite irradiance data, updating every 5 to 15 minutes. Ready to integrate via API.
You're in good company
Solcast's "Estimated Actuals" closes the gap for our owned and third-party solar portfolios.
Accurate real-time and forecasted weather data is crucial for assessing plant performance and maximizing the value of clean energy assets.
As far as we know, there's no provider that can provide a more accurate forecast.
CLOUD AND IRRADIANCE TRACKING
Tracking the world's clouds in the finest detail
Designed for Solar, from the ground up. Never rely on generic weather model data again. Solcast's real-time and forecast solar data tracks and forecasts real clouds at a resolution of 1-2km and 5 minutes. Our irradiance data and PV power data is updated every 5 to 15 minutes, downscaled to 90 metre resolution. Aerosol and albedo effects are explicitly treated.
DATA SPECIFICATIONS
Data that actually meets your requirements
Data spanning from 7 days ago to +14 days ahead, at 5 to 60 minute granularity, anywhere on Earth, providing solar irradiance data by location. Includes probabilistic forecast estimates of PV power and all types of irradiance. Actuals available in real-time. Historical data also available.
ACCURACY
Proven, replicable accuracy levels
Our forecast accuracy beats global weather models by 25% (day-ahead) to 50% (hour-ahead). Hundreds of data scientists and engineers have confirmed our accuracy, and we're willing to guarantee it. Review our accuracy verification, or contact our team to access real past forecasts for your actual sites.
PV POWER DATA
Simulate and forecast your production directly in our system
Create your own live and forecast simulated PV power data in minutes, by specifying details of your sites in a UI or programmatically. Or, have our team configure your sites using your historical production data. Separate models are used for roof VS ground mounted systems. All simulations and forecasts are powered by our industry-leading irradiance and weather data.
Data Access
Access via API or web browser download
Ready to integrate solar API directly into your systems via json or csv. Relied upon by power system operators on four continents. API uptime of >99.99%, with very low latency. Bulk API requests available. SLAs available.
Live and Forecast Data Products
