Make sure you install a blocking diode on each solar panel. This prevents reverse current flow when the sun is not shining on the solar panel. On the other hand, Bypass diodes are used in parallel-connected solar cell strings to prevent the entire string from shutting down when one or more solar cells are shaded.
In short, as diode only passes current in one direction, so the current from solar panels flows (forward biased) to the battery and blocks from the battery to the solar panel (reverse biased). What is a Diode?
Solar panels require a diode to prevent current flow from the battery to the solar panel when there is little or no light. For solar panels, a 3 amp or 8 amp diode can be used for this purpose. You might also want to install a bypass diode to prevent a shaded panel from drawing down other panels. These same diodes can be used.
In different types of solar panels designs, both the bypass and blocking diodes are included by the manufactures for protection, reliable and smooth operation. We will discus both blocking and bypass diodes in solar panels with working and circuit diagrams in details below.
We will discus both blocking and bypass diodes in solar panels with working and circuit diagrams in details below. Bypass Diode in a solar panel is used to protect partially shaded photovoltaic cells array inside solar panel from the normally operated photovoltaic string in the peak sunshine in the same PV panel.

Typical 24v Solar Array Fitting Blocking Diodes It is usual to fit the blocking diode into the positive output inside the terminal box of the solar module at the positive end of each series string. In order to minimise voltage drop and power loss it is recommended that Schottky diodes are used.
