Hi Huntingdog,
It is a matter of having sufficient storage. I started out with 875 amp-hours of Marine jars. That gave me 175 amp-hours of usable capacity. I did not bother with a generator when I was part time, so I went 5 years and never had a power problem
I've upgraded to 556 amp-hours of AGM telecom jars giving me a usable capacity of 278 amp-hours. Since I full time, I did give into getting a generator. I hate it and it ran less than 50 hours in the last year.
The panels I chose produce 3 amps of charging in the rain, and 21 amp-hours on December 21, when I am north of 49.
In an ideal world I'd move up to carbon foam jars, dump the generator, build a rack that covered the entire roof of the rv and be totally off the grid.
Unfortunately, my addictions (having food to eat, and a roof over my head) do not allow me to budget for this.
Certainly I hate dragging around a generator--but since I normally have one, upgrading the alternator is way way way down my priorities list.
