Motorhome Solar Panel Wiring

Once you have planned out the routing of the cables the wiring of a solar panel is a fairly simple task.

You must allow a small gap underneath the solar panel to allow air to circulate. Flexible panels can be mounted with screws but can also generally be mounted with adhesive. Rigid panels typically must be affixed to the roof with screws. Romex cable comes with multiple conductors encased in a second insulated covering.

For my installation of rv solar panels 10 gauge household romex wiring was chosen for a few reasons. When you hook multiple solar panels together you must observe these limitations as too much current will create heat insulation could melt and a short could cause a fire. The connection to your battery must be fused correctly. From the solar panel i connected the cables to the inlet of the double pole switch then 2 short red and black cables from the outlet of the switch to the panel connections on the solar charge controller.

As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. This is easily done using sunworks pvc solar panel mounts. Wiring tips for your rv solar power system. Wiring rv solar panels in parallel.

The process will differ depending on what type of panels you have. Wiring your solar panels in parallel increases the amperage while keeping the voltage the same. That means the 10 gauge wire works as if i had used 8 gauge automotive wire. If we have two solar panels with same voltage and power the connection will be very simple.

Solar kits normally come with solar panels a charge controller and z brackets for mounting. Each size of wire has a different current rating. 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. This prewired for solar rv included the installed charge controller but it did not have any solar panels installed from the factory.

Solid wire passes electricity at a capacity 1 size greater than stranded wire.
