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.

There are two main types of connecting solar panels in series or in parallel. There are 3 ways to connect solar panels. For more information visit the page how to wire solar panels in parallel. Nonetheless it is possible to wire them in parallel.

Parallel series and a combination of parallel and series. 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. 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. Watts volts and amps.

You connect solar panels in series when you want to get a higher voltage. 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. 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.

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

Connecting two solar panels in parallel. If you however need to get higher current you should connect your panels in parallel. The parallel connection allows to increase the current keeping the same voltage. 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. If we have two solar panels with same voltage and power the connection will be very simple. For this example i am showing you connecting panels that are for a 12 volt system. For example our 115w sunpower solar blanket has the following ratings.

Connect the negatives to the negatives and positives to the positives.
