Blocking diodes are usually included in the construction of solar panels so further blocking diodes are not required.
Cd zener diode solar panel.
Bypass diodes in solar panels photovoltaic arrays for example assume that the output of solar panel is connected to a dc battery.
Blocking diodes will be of benefit in any system using solar panels to charge a battery.
