Replication Data for: Investigating methods to improve photovoltaic thermal models at second-to-minute timescales

KU Leuven Technology Campus Ghent rooftop PV array weather data, used for the paper "Investigating methods to improve photovoltaic thermal models at second-to-minute timescales", doi: https://doi.org/10.1016/j.solener.2023.111889. This file contains raw data measured and stored at 1 s time resolution. Occasional data loss may be present; night-time data loss of ~10-20 s is due to the daily saving of the data. Original files were TDMS. Daily TDMS files converted in python and pandas to pandas dataframes (including time format conversion from Labview TDMS to python datetime), and concatenated to a continuous file. More information on the measurement set-up and data can be found in "Outdoor thermal and electrical characterisation of photovoltaic modules and systems", Bert Herteleer, PhD thesis 2016, KU Leuven. Data: from 1 May 2015 to 23 March 2016. On 24 March the cup anemometer was permanently damaged, and eventually replaced. Columns: datetime, Tamb, PV052_5x4C, PV052_5x4BS, G_Pyr_18_S, WSdir, WS datetime: pandas generated datetime, yyyy-mm-dd HH:MM:SS (original was Labview-generated timestamp). Tamb: ambient temperature, calibrated Thies Pt100 sensor 2.1280.00.000 in Weather and Thermal Radiation Shield, compact 1.1025.55.000, total combined uncertainty (k=2) = 0.4 K PV052_5x4C: PV module PV052, centre-of-module Pt100 sensor laminated against the cell, total combined uncertainty (k=2) = 0.4 K PV052_5x4BS: PV module PV052, centre-of-module Pt100 sensor on the backsheet next to the cell sensor, total combined uncertainty (k=2) = 0.4 K G_Pyr_18_S: calibrated pyranometer Kipp & Zonen CMP11, in the plane of the array (18 degree tilt, due South); calibration uncertainty 1.4% WSdir: wind direction, measured using weather vane: uncertainty 5 degrees WS: wind speed, measured using calibrated : Thies First Class Advanced cup anemometer: uncertainty 0.2 m/s between 0.3 m/s and 50 m/s.
