The comparison between PAR and EAR.

Type Advantages Drawbacks
PAR Does not require any sensors' reconfiguration algorithm or switching matrix, in opposition to the dynamic technique case [17].
Past method, the first column of the reconfigurable patterns remains unaltered [17].
The location of the modules in the TCT network is changed according to the skyscraper model in one go for all shadings [16].
This method requires more wiring; this would increase the voltage drop in the PV systems [16].
Shading effects cannot be spread uniformly across every row [16].
EAR Flexibility
Dynamically controllable
The cost increases with a dynamic technique [17].
The configuration becomes complex [17].
The reconfiguration algorithm is complex [18].
