Utility scale solar power 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 and deliver them to tens of thousands of solar farms around the world - all through a cloud-based environment on AWS providing real-time data access via API.

  • Solar irradiance and weather data (GHI, DNI, Diffuse, + meteo parameters)
  • PV power forecasting, customised to your site via machine learning
  • 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
