How To Connect Solar Panels Together

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.

How to connect solar 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. Considering the example in the figure two 5a 12v panels wired in series produce a voltage of 24v and a current of 5a. 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.

There are 3 ways to connect solar panels. There are two main types of connecting solar panels in series or in parallel. Parallel series and a combination of parallel and series. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.

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. 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. For this example i am showing you connecting panels that are for a 12 volt system.

In parallel circuits connect all the positive terminals of the solar panels and also connect all the negative terminals to help you tap this renewable source of energy.
