There are two ways to wire up solar panels.
How to wire solar panels together.
Nonetheless it is possible to wire them in parallel.
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.
You will see a symbol that looks like a triangle pointing down at a horizontal line.
For more information visit the page how to wire solar panels in parallel.
Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.
The red line is the positive connection to the panels.
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.
Firstly lets take a look at connecting solar panels in series.
When stringing in series the wire from the positive terminal of one solar panel is connected to the negative terminal of the next panel and so on.
The next basic type of connecting solar panels is 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.
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 you had 4 solar panels in parallel and each was rated at 12 volts and 5 amps the entire array would be 12 volts.
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.
Wiring solar pv panels in parallel.
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.
The parallel connection allows to increase the current keeping the same voltage.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
This is the first part of our video on how to connect your panels in series and parallel.
