This video covers some tricks on how to attach solar panels on the roof of your RV that allows for complete flexibly of placement, replacement. portability and upgradeability. The key trick is to use strut channel as the base for attaching the panels to the roof.
Here is a list of the components that I cover with links to where you can purchase them. (Disclosure: Some of these are affiliate links. If you click through and purchase an item I will get a small kickback at no extra cost to you. Any little bit I can make helps build the channel and is appreciated.)
All things solar can be found at Continuous Resources (Link https://tinyurl.com/y25awjeu) at good prices and with knowledgeable support. I have purchased quite a bit from Matt and he has been super helpful when I have had questions.
