Solar forecasting technology… in the cloud

We built a new approach to solar forecasting technology from the ground up, using the latest in weather satellite imagery, machine learning, computer vision and big databases. We crunch more than 600 million new forecasts every hour in a cloud-based environment on AWS and provide real-time access to our data via API, including:

  • Solar irradiance data (GHI, DNI, Diffuse)
  • PV power modelling (Rooftop or Utility Scale)
  • Global coverage (all six major continents)
  • Rapid update (new forecasting data every 5-15 minutes)
  • Proprietary cloud & aerosol detection (tracking smoke, dust, haze)
  • Probabilistic forecasting data (P50, P10, P90)
  • High-resolution data (1-2km)
  • Forecasts from 5 minutes through 7 days ahead
  • Choose between 5/10/15/30 minute resolution
  • Delivered via REST API (download CSV, JSON or XML)
