How we calculate it
- The irradiance forecast comes from Open-Meteo, requested for the same plane our yields were computed for: 35° tilt, facing south.
- Irradiance is multiplied by 86% to get production at the inverter output — the same system loss the PVGIS figures carry.
- The seasonal normal is the PVGIS monthly figure divided by the days in the month, per city.
- Data refreshes once an hour.
Estimate my savings
The estimate uses measured irradiation data for your municipality from the European Commission's PVGIS database, with deliberately conservative assumptions. All prices are in KM.
