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 Cover
Detailed global satellite observations that capture cloud cover with precision
We model local cloud cover using 1-2km grid, downscaled to 90 metre resolution to model aerosols, irradiance and terrain effects for a more precise and accurate global snapshot of historic solar irradiance.
Validation
Dataset supported by independent global validation
The data has low uncertainty and a quantified error range, making the data suitable for resource assessment, yield analysis, financial modelling, and any application requiring precision irradiance data.
Data Access
Access via API or Solcast web Toolkit
Ready to integrate solar API directly into your systems via json or csv. API uptime of 99.9% with very low latency.
Bulk extract data using the Solcast API Toolkit.
Integration
Direct integration with major PV simulation software
Full suite of weather data from leading reanalysis datasets completes the collection of 20+ parameters available.
Data coverage from 2007 to 7 days ago, from hourly to 5 minute resolution.
Data available in formats ready to import into PVsyst, SAM, PV*Sol, PlantPredict, Helioscope, + more.
