To answer the questions:
Interesting idea. I take it there is NO connection to any utility.
It is plugged into 30 amp pedistal. The boat in in front of it.
I'm curious ... are any steps taken to bond neighboring barges to each other?
We typically do not tie them together. When we do, we hardwire them together and use the power from only one barge for both. The only time they are tide together is winter storage. We do not typically have a need for so may folks in one spot at a time.
Design question... Why are the solar panels off the side like that, instead of on the roof or another less obtrusive location?
The arrays are actually on the aft (rear) of the barge. I do not know exactly way it was designed this way but I am glad they did it this way. I just replaced the panels and with the ability of rotating and flipping the arrays allowed them to be serviceed all of them with nothing more the a 2-step, step ladder. It also allows personnel who is setting it up to aim the arrays for optimum performance. Pointing the whole barge for the best performace it not always an option. We have about a 45 degree field of view for the arrays. Then there is the snow to deal with and it presents a lower wind profile which both can get really bad up here. Worst in the winter.
