Key performance metrics.

Parameters [Ref.]	Definition/Aim	Formula
Fill factor (FF) [37]	Determined as the ratio of the global power under PSC to the product of the open-circuit voltage and the short-circuit current.	$FF = \frac{{GP}_{(PSC)}}{V_{O C} \times I_{S C}} \times 100$
Shading loss (SL) [37]	Reveals the amount of the power degraded under PSC.	$SL = {GP}_{(STC)} - {GP}_{(PSC)}$
Global power (GP) [58]	Evaluated as the product of the peak voltage and current.	$GP = V_{P} I_{P}$
Performance Ratio (PR) [59]	Evaluated by dividing the global power under PSC and no shading conditions.	$ER = \frac{{GP}_{(PSC)}}{{GP}_{(STC)}} \times 100$
Power gain (PG) [60]	Calculated with respect to the benchmark solar array (TCT).	$PG = \frac{{GP}_{(NEW)} - {GP}_{(TCT)}}{{GP}_{(NEW)}} \times 100$
