In different types of solar panels designs, both the bypass and blocking diodes are included by the manufactures for protection, reliable and smooth operation. We will discus both blocking and bypass diodes in solar panels with working and circuit diagrams in details below.
However, most of the solar panel array already has a built-in bypass and blocking diodes. Nevertheless, you still have to be careful. I hope this article helped you in learning about blocking diodes and how they are necessary for solar panels.
With a small 6V solar panel, the losses in the diode would exceed the power which would have been lost as dark current, but for a 12 Volt system or higher, a blocking diode should always be used. The diodeshould be fitted into the positive leg of the circuit between the fuse and the battery.
The most case (99%+), no need a Blocking Diode if do not connect the solar panel on battery directly. The blocking diode is not for block current from the other parallel solar panel. Indeed, a blocking diode will be installed in the charge controller or string inverter. I recently installed some used PV panels on a 24 Volt PV / Inverter system.
When connecting diodes, it's important to ensure the cathode is connected to the positive terminal of the solar panel and the anode is connected to the negative terminal of the solar panel. In case you do the opposite, the current will be blocked, and your solar panel won’t work. To connect the diodes, you need the following tools:
For example, if you're using a 12-volt solar panel to charge a 12-volt battery, you'll need a diode with a reverse voltage of 24 volts. The reverse voltage determines the amount of power that can be dissipated by the diode. If you're working with high voltages, you'll need to choose a diode with a higher reverse voltage.
