Brad, You mentioned waxing the solar panels. I was just thinking of using RainX. It really works well on my windows. I rarely use my windshield wipers when I have a new coat of RainX on it.
As far as blowing out water lines...I have done it successfully on travel trailers but the plumbing in your Newell is more complicated..It only takes one low spot that is completely filled with water to freeze and burst...Usually those low spots are behind the cupboards!!. I have always used RV antifreeze in my Newells with the water heater bypass and have never had a problem.
Also, If your panels are fixed flat on the roof I wonder if there would be benefit to constructing a reflective "wall" right beside them along the north side of the panel to reflect more solar onto the panel.
