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
