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.
Install and wire a solar panel to a solar controller.
The best method would use a cable entry plate and a wire that is run all the way to the battery and is already fused and the location of the charge controller already chosen.
The positive wires are connected to a positive connector within a combiner box and the negative wires are connected to the negative connector.
Connect the solar array.
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 distance of the panels use junction boxes to neatly wire the panel terminals together.
Make sure to screw in the exposed wire tightly inside the controller terminal.
Then screw on the battery rings to the battery.
Second then connect your solar panel to your charge controller.
Connect the inverter to solar battery.
Make sure that you lead the wire into the battery terminal of the charge controller and match the and to the battery and.

Solar power system wiring steps.
So if you have solar panels right on your roof and want to do in parallel you can but you need heavier gauge wire to do it than you would need were you to do 24v.
If you want to take your panels off the rv and run them a bit of a distance so you can park in shade and put panels in the sun some camp sites setup would block too much sun where the camper is then going 24v means you can run longer wires with the same gauge.
Mount your solar panels step 2.
Install your inverter optional.
Connect the solar battery.
Connect your charge controller.
This type of connection is really efficient if the following conditions are met.
Solar panel charge controller wiring diagram.
This prewired for solar rv included the installed charge controller but it did not have any solar panels installed from the factory.
Connect the pv array.
