Radically different sized RV solar. Plus solar projects.

So how about some numbers .......
Solar watts Vs Battery amp/hrs
Give it a shot
We will be kind to you (well at least most of us)

From what I can see there realy is no such thing as a rule of thumb for determining battery size Vs solar array wattage - For us the more PV panels up there the better off we are with the only limiting factor being the roof where those darn shadows do not get in the way
