12V roof solar panels

– If adding another solar panel/s to an existing roof solar setup, you don’t need to buy a solar controller since the trailer should already have one inside on a wall.
– Don’t bother with 100 watt panels on the trailer roof. Labor is the largest cost.
– If your trailer already has a factory solar panel, it is most likely 12V. Purchase another 12V panel (matching the wattage as close as possible) and a parallel splitter/adapter. Most are 175-200 watt from the factory.

Roof panel accessories

Note: If there isn’t an inline fuse, you’ll want to put a circuit breaker on the positive cable between the solar panel and solar controller.
