Basically, they installed connectors and undersized wiring for you.
The "Solar on the side" is made for a portable panel that has an integral charge controller type thing. Usually very small wattage (<100) systems.
The roof top solar is just the rooftop connectors and undersized wiring. You have to buy a charge controller and panels at a minimum. You should have a sticker inside your camper staying where they want you to put the controller. In my 29.5BHDS it is no where near the battery, which makes it a very poor choice of location. This, along with the wiring would lead to disappointing performance.
Gopower provides the components to Jayco for installation in hopes of selling lots of their over priced systems.
