title: Photovoltaic Inverter Production and Meteorological data

description: Inverters Files

These files contain measurements of the power produced by the facility’s PV panels. The data were collected from the inverters and retrieved using the Prometheus interface. The facility consists of three (3) PV racks of different sizes. Specifically:



rack-1 (PV1): 107.1 m2

rack-2 (PV2): 95.2 m2

rack-3 (PV3): 57.8 m2


Each file includes the following columns:





date: Timestamp of the measurement (recorded every 15 seconds)




inverter1: Power produced by PV panel 1 (W)




inverter2: Power produced by PV panel 2 (W)




inverter3: Power produced by PV panel 3 (W)



The file names indicate the date range covered by the data they contain:





inverters_03.11.2023-09.02.2024.csv




inverters_18.04.2024-04.05.2024.csv




inverter_07.06.2024-25.06.2024.csv



Math model Files

These files contain hourly data for the mathematical models. They include weather variables retrieved from the Open-Meteo API (open-meteo API), solar angle information computed with the Astral library (astral library), intermediate variables used internally by the model, the true power values produced by the PV panels, the corresponding predicted values, and the resulting percentage error.

Columns





datetime, time: Timestamps of the hourly measurements




inverterX: True power produced by PV panel X

azimuth, zenith: Solar angles calculated using the Astral library




Gpoa (W/m²): Internal variable required by the mathematical model




energyX: Predicted energy or power produced for PV panel X




errorX: Percentage error for PV panel X



Note: For the file math_model_all_inverters_03.11.2023-25.06.2024.csv, the suffix X is omitted from the columns names. This file corresponds to a trial where all inverters were treated as a single group to produce one unified model.

Like for the inverters files the file names indicate the date range covered by the data they contain:
