Photovoltaic generation data, for 3 years, regarding the 2022-3 Competition on solar generation forecasting

These data were released under the 2022-3 Competition on solar generation forecasting. Please check our competitions: www.gecad.isep.ipp.pt/smartgridcompetitions The data set comprises the power generated by photovoltaic panels and data collected from a near weather station. The data was collected in 5 minutes periods. Data comprises: Hour Starting minute (inclusive) Ending minute (exclusive) Generated power (kW) Temperature (ºC) Dewpoint (ºC) Pressure (hPa) Wind Direction (Degrees) Wind Speed (KM/h) Wind Speed Gust (KM/h) Humidity (%) Hourly Precipitation (mm) Daily rain (mm) Solar Radiation (Watts/m2) The data set represents raw data without any treatment, this means that it is possible to find errors. Data can have missing data or missing reading periods, and a fixed zero (0) value, indicating a failure in the system readings. We would be grateful if you could acknowledge the use of this dataset in your publications. Please use the Zenodo publication to cite this work.
