Shunt-mode Solar Charge Controller
In a shunt-mode circuit, the solar panel is connected to the battery via a series diode. The diode prevents battery current from flowing back through the PV panel at night.

Bypass diodes in solar panels are connected in “parallel” with a photovoltaic cell or panel to shunt the current around it, whereas blocking diodes are connected in “series” with the PV panels to prevent

This use of bypass diodes in solar panels allows a series (called a string) of connected cells or panels to continue supplying power at a reduced voltage rather than no power at all.

2.5.4 Bypass diode The bypass diode is placed in parallel with the photovoltaic module or panel (Figure 2.41). A bypass (or shunt) diode allows current to bypass the module (or group of cells) or panel in

The bypass diodes are usually placed on sub-strings of the PV module, one diode per up to 20 PV cells. This configuration eliminates the creation of hot-spots and enables the PV modules to operate with

When one solar cell of the panel is shaded while the others are illuminated, a hot spot could appear and leads to the shaded cell destruction. The bypass diode is an efficient solution to eliminate the “hot
