Are blocking diodes really needed for solar panels in parallel?
If one connects two technically identical solar panels in parallel (to increase current), many sources suggest to put each of the panels in series with a Schottky diode before joining these branches together in parallel. The rationale behind this seems to be that one of the panels does not drive a current through the other panel in forward
Connecting Solar Panels in Series or in Parallel?
Can I wire solar panels in series and parallel? Yes, you can wire solar panels in series or parallel. In some cases, you can even wire solar panels in both series and parallel simultaneously. For example, if you have two panels with 12V each, wire them in series to start. Then, assuming you have another 24V panel, you can wire them together in
How to Connect Diode to Solar Panel
To prevent reverse bias from happening, you need to connect a diode between the solar panel and the battery. This way, when the voltage of the solar panel is higher than the voltage of the battery, the current will flow through the diode and into the battery, instead of flowing back into the solar panel.

6 FAQs about [Do you need to add diodes when connecting solar panels in series ]
How do I connect diodes to a solar panel?
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:
Can a diode help a solar panel?
This is again where diodes can help us. If we now put a diode over each cell in the panel, then if one cell is shaded the total voltage will drop by 0.6V but the current from the other cells will still get through, because the diode allows the current to bypass the shaded cell.
How to choose a solar diode?
It is therefore important to choose particular diodes, called Schottky diodes, which can safely withstand the current of the panels and which have a very low threshold voltage. The lower the threshold voltage, the lower the dissipation of solar power on the diode.
What is the difference between a diode and a solar panel?
Solar panels consist of solar cells that convert sunlight into electricity through the photovoltaic effect. Mainly, we use two kinds of diodes for effective solar panels – bypass and blocking diodes. You may be wondering, what is the difference? Well, not much.
Why do solar panels have a 'blocking diode'?
The rationale behind this seems to be that one of the panels does not drive a current through the other panel in forward direction (hence the name "blocking diode", as opposed to the bypass diodes that are part of modern panels anyway).
What are the different types of solar diodes?
Two types of diodes are available as bypass diodes in solar panels and arrays: the PN-junction silicon diode and the Schottky barrier diode. Both are available with a wide range of current ratings. The Schottky barrier diode has a much lower forward voltage drop of about 0.4 volts as opposed to the PN diodes 0.7 volt drop for a silicon device.
