DOCUMENTATION FOR PV data

In the experiments, we applied poly-crystalline XHYG-10W and mono-crystalline XKD-50W PV modules, whose
technical parameters are listed as follows.
PV module XHYG-10W XKD-50W
Cell Technology Poly-Crystalline Mono-Crystalline
Maximum Power 10 W 50W
Voltage at Maximum Power Point 9V 17.82V
Current at Maximum Power Point 1.12A 2.8A
Open-circuit voltage 10.71V 22.02V
Short-circuit current 1.23A 3.18A
The number of cells 20 36

The experiments used four-series connected PV modules operating under
both UICs and PSCs. The PV cellswere shaded by light films to simulate different PSCs. AYHT309
thermometer with Type-K thermocouple probes was installed to measure the temperature of the PV panels. The solar
irradiance was measured by a standard 2 cm2 cm mono-crystalline PV cell which has been calibrated by the National
Institute of Metrology, China. A Fluke F289C multimeter measured the cell’s short circuit current. A PROVA-1011
PV system analyzer has the capability of generating the I-V data under a specific environmental condition.

In the dataset, there are 24 testing cases by using multiple-level numbering. The first item indicates the number of irradiance
levels receiving by the applied PV string, while the second item represents the case number. For example, “4-2" means
the second test case with four different irradiance levels. All the data were collected at the Xi’an Jiaotong-Liverpool
University’s south campus (east longitude 120o75’, north latitude 31o28’) in March 2021.

The column headings for the tabular data are defined as follows:

I terminal current (A)
V terminal voltage (V)
T temperature (oC)
