For my installation of rv solar panels 10 gauge household romex wiring was chosen for a few reasons.
Rv solar panel wiring.
Wiring our rv s solar panels in series has worked out just fine.
In my case with four 100 watt solar panels to work with the solution was to connect 2 solar panels together in a parallel configuration.
Solid wire passes electricity at a capacity 1 size greater than stranded wire.
Do the same with the second set of 2 solar panels so you have 2 separate 12 volt 200 watt solar panel arrays.
Here s how i wired my solar panels for rv boondocking why i chose 10 gauge romex wiring.

Be sure to consult the instructions provided with any.
That means the 10 gauge wire works as if i had used 8 gauge automotive.
This creates a 12 volt 200 watt combination.

So if you wire together a 100 watt solar panel and a 175 watt solar panel in parallel you ll get a total of 275 watts.
That means if you wire panels with different wattages the overall outcome won t be affected.
