For anyone interested in the Renogy kits for Solar, the starter kits do come with almost everything you need to get going. I am not fully installed yet. Still deciding how to best mount the panels on the roof.
Here are the details of the panels if you are interested.
I have room for 4 in future, and 400w is what the charge controller will take. Might be overkill, but we will see.
I have read its best to mount solar at a 30degree angle. After some back and fourth in a few groups I am not going to worry about the 30 degrees. My thinking is that I will care more about placement for campsites, comfort etc rather than solar. Most people that rig up adjustable panels don't often use it from what I have been told. So If I mount two on the front they will both be at 10 degrees and granted we get direct sunlight on the roof should charge the battery in a few hours. If I was doing more than just camping It might be a bigger issue.
Power panel is coming along, the kit comes with tones of wire for my application, I imagine if you are getting one for your larger RV or any small trailer you will be happy.
Haven't finished mounting the panels yet, before I drill more roof holes I want to ensure I have a final placement and am on the fence of mounting some sort of roof rack.
