How To Connect Two 12v Solar Panels

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.

How to connect two 12v 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. 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.

Wiring pv panel to charge controller 12v battery 12vdc load. To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below. The first way i am going to talk about is parallel because this is probably the most common way that panels will be connected. Connect the negatives to the negatives and positives to the positives.

The parallel connection allows to increase the current keeping the same voltage. If both panels are rated at the same maximum voltage then you ll get maximum output. To power a dual battery system you ll need to connect the panels in parallel. Parallel series and a combination of parallel and series.

Nonetheless it is possible to wire them in parallel. In this simple solar panel wiring tutorial we will show how to connect a solar panel to the solar charge controller battery and direct dc load according to the rating.
