Blocking Diode For 12v Solar Panel

Blocking diodes will be of benefit in any system using solar panels to charge a battery.

Blocking diode for 12v solar panel. This is where a solar panel blocking diodes is used. When a solar panel is shaded the output current reduces dramatically and when it s dark it actually absorbs current. 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. The diode is able to stop this backwards flow and ensures that the energy collected is safely stored. 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. All the energy is in the battery and it wants to escape.

Now let s consider what happens if one of the panels in the above diagram is shaded. There are two functions a diode can perform in 12volt solar systems either as a blocking diode or as a bypass diode.

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.

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