Blocking Diode For 12v Solar Panel

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.

Blocking diode for 12v solar panel.

Blocking diodes will be of benefit in any system using solar panels to charge a battery. This is where a solar panel blocking diodes is used. Now let s consider what happens if one of the panels in the above diagram is shaded. All the energy is in the battery and it wants to escape.

The energy flow is now reversed and escapes out through the solar panel.

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.

Now you re thinking brilliant i will just get a 12v solar panel blocking diode. The 12v solar panel is still connected but not generating power. Blocking diodes are usually included in the construction of solar panels so further blocking diodes are not required.

When a solar panel is shaded the output current reduces dramatically and when it s dark it actually absorbs current. 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. This is a real problem at night because we could lose all the power we gained during the day.
