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.

How to connect 2 solar panels together.

If we have two solar panels with same voltage and power the connection will be very simple. For more information visit the page how to wire solar panels in parallel. Connecting two solar panels in parallel. For this example i am showing you connecting panels that are for a 12 volt system.

There are 3 ways to connect solar panels. 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. Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. Connect the negatives to the negatives and positives to the positives.

The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector. Parallel series and a combination of parallel and series. 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. Watts volts and amps.

The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. You connect solar panels in series when you want to get a higher voltage. The parallel connection allows to increase the current keeping the same voltage. 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.

Maximum rated voltage 19 8v. If you however need to get higher current you should connect your panels in parallel. Then they are connected to the charge controller or to the inverter of the solar system. There are two ways to wire up solar panels.

Maximum rated current 5 8a. Wiring solar panels in a parallel circuit. If both panels are rated at the same maximum voltage then you ll get maximum output. 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.

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.
