Usually modules are equipped with three solar bypass diodes inside the pv junction box.
A solar panel work as a diode.
A solar panel consists of multiple solar photovoltaic cells that are electrically connected in series to increase the output voltage by the number of cells in the circuit.
The purpose of a bypass diode is to allow electricity in a solar panel to flow around the shaded cell.
The blocking diodes and bypass diodes are physically same but their functionality is different.
There are two approaches that manufacturers take to build solar panels that work better in partial shade conditions like this.
For each parallel brach of solar panels we will use a single blocking diode.
In order to maximize the energy output in the presence of shades solar panel manufacturers decided to include bypass diodes in the junction box located in the rear side of the module.
Some solar panels are constructed with the cells divided into groups each group having a built in by pass diode.

In this video you will learn the importance of a bypass diode in solar panel learn how to connect a bypass diode to your own solar cells to improve the eff.
They are also used as bypass devices to maintain the reliability of the entire solar power system in the event of a solar panel failure.

The first and most common is to use an electronic component called a bypass diode.
Bypass diodes are electronic devices that will act whenever there are partial shadings in a module.
Since the prevent backflow of current unidirectional flow of current they are used as blocking devices.
Blocking diodes are also called as series diodes or isolation diodes.
Most modern solar panels have at least 3 bypass diodes which means that a small bit of shade or bird poo should only cause you to lose a third of your panel s power.
Diodes are extensively used in solar panel installations.
These diodes provide the separate path for the current to flow when the solar panels are shaded or damaged.
