Therefore, there are two main types of diodes used in solar systems: Blocking diodes: blocking diodes allow current to flow from the solar panel to the battery, but prevent/block current from flowing from the battery to the solar panel, thus preventing the battery from discharging.
Diodes are widely used in solar panel installations. They are used as blocking devices because they prevent current backflow (unidirectional flow of current). They are also used as bypass devices to maintain the reliability of the entire solar power system in case of solar panel failure.
A modern solar panel has 3 junction boxes on the back for 3 bypass diodes. Here you can see the diodes inside the junction boxes: Bypass diodes circled. As the name suggests, bypass diodes are used to bypass shaded solar cells. They stop shaded, high-resistance cells from getting ‘hot spots’ and reduce the power loss in the partially shaded panel.
Make sure you install a blocking diode on each solar panel. This prevents reverse current flow when the sun is not shining on the solar panel. On the other hand, Bypass diodes are used in parallel-connected solar cell strings to prevent the entire string from shutting down when one or more solar cells are shaded.
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:
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). What is a Diode?
