I am looking to add about 1000-1500 watts of solar to RV trailer and I have one side wide open but there is only 36.5" from edge of trailer to the AC unit. There is 28' of length available though.
All of the panels that I am finding to maximize my roof space are 39" wide.

I will be using MPPT solar charger and I don't believe that the '12 volt' panels will be as efficient use of roof space.

Are there other panels that I am not aware of?
