Description
Datasets of Solar PhotoVoltaic Power (SPV) are computed through a mix of physical and statistical model. SPV capacity factor (CFR) is defined as the ratio of actual generation over installed capacity (sum of the peak capacity of all PV systems installed in the region of interest). The solar PV capacity factor is calculated at grid point level. It is important to highlight that this quantity does not represent the power production of a single PV system. Instead, it is designed to represent the aggregated production of the PV plant installed in each pixel. For this purpose, the power production of a PV system is calculated from the meteorological data (GHI and 2 m temperature) for different module orientations taking a reference PV plant model and using empirical models of the main parts of a PV system (optical losses, module, inverter). These different power values are then aggregated assuming a distribution of the different module orientations for the considered location. The distribution of module orientation is dependent on the location via the optimal tilt angle using a parameterization developed in the C3S ECEM contract.

Historical: 1-hour time step as accumulated value. Averages for daily, monthly, seasonal (DJF, MAM, JJA, SON) and annual are also computed for NUTS0 and NUTS2 mean values. |
Seasonal Forecasts: 24-hour time step as accumulated value (gridded data). Averages for monthly, seasonal (DJF, MAM, JJA, SON) and annual are also computed for NUTS0 mean values. |
Projections: 3-hour time step as accumulated value (gridded data). Daily NUTS0 and NUTS2 averages are also computed. |
Time period
Historical: 1979 to present (ca. 1 month behind real time); updated every month based on ERA5T data availability. | ||||
Seasonal Forecasts: The hindcasts cover the period 1993-2016 for the three models used by C3S Energy: ECMWF Sys5, Météo-France Sys7 and UK Met Office Sys14. ECMWF has all the month, MTFR SY07 currently covers October to April with the rest of the months to be completed by mid- May 2020 as this is a new system. METO SY14 ranges from June to April (notice that METO SY14 is a rolling release model, hindcast have to be computed each months). The forecasts updated have been run every month from the first month of availability in the current version on the CDS: | ||||
Forecast availability | Forecast horizon | |||
ECMWF Sys5 | From January 2017 | 215 days (24-hourly time steps) | ||
MTFR Sys7 | From October 2019 | 211 days (24-hourly time steps) | ||
METO Sys14 | From June 2019 | 215 days (24-hourly time steps) | ||
Projections: 1980 to 2098 (common period), with historical forcing to 2005, then RCP forcing. |
Spatial resolution
Historical: 0.25° by 0.25° latitude/longitude. Data are also available as averages for more than 30 European countries (NUTS0) and ca. 350 NUTS2 areas. |
Seasonal Forecasts: 1° by 1° latitude/longitude. The underlying forecast systems run at different resolutions. Data are also available as averages for more than 30 European countries as NUTS0 areas. |
Projections: 0.25° by 0.25° latitude/longitude. Data are also available as averages for more than 30 European countries (NUTS0) and ca. 350 NUTS2 areas. |
