How To Connect Solar Panels Together

There are two main types of connecting solar panels in series or in parallel.

How to connect solar panels together. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. Wiring solar panels in a parallel circuit connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. Connecting solar panels in parallel wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.

You connect solar panels in series when you want to get a higher voltage. There are 3 ways to connect solar panels. A series circuit requires you to connect the first positive terminal of the solar panel to the negative terminal of the next solar panel to get the current flow through the circuit. Then they are connected to the charge controller or to the inverter of the solar system.

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. As clearly visible in the picture it is sufficient to wire the positive pole of one panel to the negative pole of the other and at the output we will find a doubling of the voltage. For this example i am showing you connecting panels that are for a 12 volt system. Considering the example in the figure two 5a 12v panels wired in series produce a voltage of 24v and a current of 5a.

The type of your solar panels system the solar power you want to generate the other system components such as a charge controller battery and inverter.
