Connecting two solar panels in parallel.

How to connect 2 solar panels together.

When you are looking to connect solar panels produced by different manufacturers together the problem does not come from different manufacturing styles or cell type it comes from the electrical characteristics of the solar panels. Wiring solar panels in a parallel circuit. For example our 115w sunpower solar blanket has the following ratings. If both panels are rated at the same maximum voltage then you ll get maximum output.

If we have two solar panels with same voltage and power the connection will be very simple. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. 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. Maximum rated current 5 8a.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected.

If you however need to get higher current you should connect your panels in parallel. 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. For this example i am showing you connecting panels that are for a 12 volt system. There are two main types of connecting solar panels in series or in parallel.

Connect the negatives to the negatives and positives to the positives. There are 3 ways to connect solar panels. If you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps the entire array would be 12 volts at 20 amps. Watts volts and amps.

There are two ways to wire up solar panels. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. If we have two or more solar panels with the same voltage but with different current it is not possible to wire them in series. 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.

The parallel connection allows to increase the current keeping the same voltage.
