How To Wire Solar 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.

How to wire solar panels together.

The next basic type of connecting solar panels is in parallel. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together. You will see a symbol that looks like a triangle pointing down at a horizontal line. This is the first part of our video on how to connect your panels in series and parallel.

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 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. Wiring solar panels in a parallel circuit connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels. The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.

Nonetheless it is possible to wire them in parallel. How to wire solar panels in parallel place the panels close to each other and oriented to the sun at the same angle check that the panels do not shade each other and that they are far from possible causes of shading choose an appropriate section of the electrical cable according to the. There are two ways to wire up solar panels. Firstly lets take a look at connecting solar panels in series.

Wiring solar pv panels in parallel. The red line is the positive connection to the panels. When stringing panels in series each panel additional adds to the total voltage v of the string but the current i in the string remains the same. The parallel connection allows to increase the current keeping the same voltage.

Connecting solar panels in parallel is just the opposite of series connection and is used to increase the total output current of the array and hence the total output power while 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. 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.
