World Solar Radiation API

Instantly retrieve the latest solar irradiance forecast and real-time "live" data for any location around the world.

We crunch gigabytes of satellite data on the fly in just seconds to deliver you the latest solar irradiance data

We built an entirely new approach to solar irradiance modelling using the latest in high-resolution weather satellites, machine learning, computer vision and big data. We crunch nearly 10TB of input data every month in a cloud-based environment on AWS and provide real-time access to our data via API. Our Live and Forecast solar irradiance data products include:

  • Solar irradiance data (GHI, DNI, Diffuse)
  • Forecasts from 5 minutes through 7 days ahead
  • Available from real-time through 7 days ago
  • Global coverage (all six major continents)
  • Rapid update (new irradiance data every 5-15 minutes)
  • Exceptionally low latency (tens of seconds for computation)
  • Proprietary cloud & aerosol detection (tracking smoke, dust, haze)
  • High-resolution data (1-2km)
  • Choose between 5/10/15/30 minute resolution
