SolarSat delievers radiation data independent of measurement instruments for any site worldwide. Radiation is retrieved from satellite images. Air temperature data is taken from weather forecast models.

Our satellite-based global radiation data has a precision of 20% (rel. RMSE) for hourly values, 10% for daily values, and 5% for monthly values. The precision of SolarSat lies in the same range as the precision of radiation sensors (5-10%), but it does not suffer from problems like stain or disruptions.

With SolarSat you get—at a good price—precise, consistent, and reliable data for monitoring your PV plant, without having to rely on measurement instruments or other infrastructure on site.

With SolarSat Standard you get quarter-hourly data for the last 24 hours and the following parameters:

  • Global radiation [W/m2]
  • Air temperature [°C]

With SolarSat Advanced you additionally get the following parameters and options:

  • Direct and diffuse radiation [W/m2]
  • Direct normal radiation [W/m2]
  • Clear sky radiation [W/m2]
  • Global radiation on the inclined plane [W/m2]
  • Reference yield (for standard module and standard inverter) [Wh/kWp]
  • Values for the last 168 hours
