Has anyone added solar panels to the roof of a 2018 21 BHS?

I am not sure that the roof is the best place for a solar panel on an RV. Do you always camp in sunny spots? If so ok, but most who boondock (which is where you would need solar) camp in shady spots. Merlin on the aluminumcamperforum and a friend of mine both installed portable panels that work well for them. These let you move the panels to follow the shade.

But if you want to install them on the roof, ok. I would use thickened epoxy to glue the mounting brackets to the aluminum roof if that is what you have. If you have the elastomer roof, I don't know. Maybe screw through the elastomer to the subroof.

Running the cable is another problem with a roof installation. Maybe through an existing item on the roof like the antenna or fan and down inside of the wall down to below the floor where you can run it to a controller near your battery.

In one of the newsletters on the aluminumcamperforum I wrote an article about how to install a portable 100-200 watt solar panel system which should be plenty for most users needs. Note that the article first tries to talk you out of solar by installing bigger batteries first  ;).

Solar panel article here: https://mailchi.mp/fc579d244794/aluminum-camper-forum-newsletter?e=098d190c6d

Since I wrote it, Victron has come out with a series of MPPT controllers that are priced competitively with quality PWM controllers and I would recommend the Victron.
