Method and data

Every city uses a 10 kWp system facing south at 35 degrees with 14% system losses. Tomorrow's figure combines hourly weather with GridPassport's PV production and uncertainty model. The monthly profile uses the European Commission JRC PVGIS multi-year climate series. Roof direction, shade, snow, dirt, inverter clipping and local weather can change real output.
