Yes you can mount RV Solar Panels on the roof of your RV and if you want to supplement the power you use in your RV with free solar energy you should use an RV Solar Panel Kit on your RV just like I do.
Depending on the power generating capabilities of Solar Panel Kit you have; you can use it to simply charge your RV house batteries or use the battery stored solar energy to run both 12 volt and 120 volt appliances in your RV.
You can also go to the extreme like Brian Brawdy has to use both solar and wind energy to power everything in his camper and travel trailer. Watch the video below to see what I mean.
