A Standard PV module model with 60 or 72 PV cells connected in series with 3 bypass diodes.
The bypass diode is activated during shade condition allowing current to bypass through the shaded cells group, hence minimizing the current losses.
The 3 bypass diode divided the entire PV module into 3 vertical areas each area can contain up to 20 cells for 60 cells module or 24 cells for 72 cells module.
