How To Wire 2 Portable Solar Panel Together

Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.

How to wire 2 portable solar panel together.

Solar panels are usually connected in series to obtain higher output voltage. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller. If you look at the arrows along the white and red lines they are showing the direction of flow. If we have two solar panels with same voltage and power the connection will be very simple.

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. Firstly lets take a look at connecting solar panels in series. In this first image there are 3 solar panels. Two arrays connect in parallel to one 20a charge controller run cable to battery bank.

There are two ways to wire up solar panels. Connect the negatives to the negatives and positives to the positives. Yes the results are virtually identical. Connecting 2 130w folding solar panel sets together.

Two arrays two 10a charge controllers connect both in parallel to the same battery bank. To power a dual battery system you ll need to connect the panels in parallel. Connecting two solar panels in parallel. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same.

When you connect two or more solar panels like this it becomes a pv source circuit. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another. Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array which are to be connected to the input either of the inverter in case of a grid tied system without a battery backup or the charge controller in case of a grid tied system with a battery backup or off grid solar panel system. If both panels are rated at the same maximum voltage then you ll get maximum output.
