Blocking Diode For 12v Solar Panel

This is where a solar panel blocking diodes is used.

Blocking diode for 12v solar panel.

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. 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. The diode is able to stop this backwards flow and ensures that the energy collected is safely stored. Now you re thinking brilliant i will just get a 12v solar panel blocking diode.

Blocking diodes will be of benefit in any system using solar panels to charge a battery. There are two functions a diode can perform in 12volt solar systems either as a blocking diode or as a bypass diode.

The 12v solar panel is still connected but not generating power.

The energy flow is now reversed and escapes out through the solar panel. When a solar panel is shaded the output current reduces dramatically and when it s dark it actually absorbs current. Not only will that panel not be producing any significant power but it will also have a high resistance blocking the flow of power produced by the unshaded panel.

All the energy is in the battery and it wants to escape. This is a real problem at night because we could lose all the power we gained during the day. Blocking diode in a solar panel is used to prevent the batteries from draining or discharging back through the pv cells inside the solar panel as they acts as load in night or in case of fully covered sky by clouds etc.
