Tak, the thing about RV solar is that it needs to be tailored to the user, every installation should be custom. I see a lot of posts on this Forum and elsewhere where the owners are looking for advice because there "kit system" isn't providing what they need.
The absolute first step for solar RV is doing an energy audit to find out how many amp hours are used daily and how the owner wants solar to reharge for that use. Here is a spreadsheet used to determine energy use. After the use is calculated and the purpose is defined (i.e. "I want my solar panel to charge my batteries while in storage" or "I want enough power to recharge my batteries for my daily use"), system size can be outlined.
The good news is that solar modules are at an all-time low price and can be had inexpensively. Depending on your needs, a controller can be fitted for your present and future use. Give us a bit more information on what you have for batteries and RV, how you camp, and what you want solar to do.
