Parallel connection of two identical solar panels.
How to parallel wire solar panels.
If we have two solar panels with same voltage and power the connection will be very simple.
The first thing to do is figure out what kind of connectors you ve got on your solar panel.
To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below.
When solar panels are wired in parallel the positive terminal from one panel is connected to the positive terminal of another panel and the negative terminals of the two panels are connected together.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
You do not want to wire more than 2 panels in parallel using couplers because this does not give you over current protection between the two panels.
As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one.
In our demo we have an mc4 compatible locking connector.
