Because I will rarely have shore power, I expect to need to expand my solar wattage. Also, the best remedy for the myriad limitations (low light conditions, winter sun, rainy days, flat laying panels, parasitic losses, line losses, etc.)seems to be to have more wattage. Once I bite the bullet and pay for a good MPPT controller, then the 24v panels are the cheapest way to get lots of wattage with the smallest footprint.
I am leaning toward poly over mono because I can move the rv around, but cannot move the sun. So there is more control over reducing shade impacts than over low light conditions?
I am thinking of starting with (1) 270w panel and the MPPT 60 amp controller. Or maybe even start with (2) 270w panels? Still thinking. Probably cost effective to do the two panels and have plenty of wattage for now, and still not limited in expanding in the future? I have been seeing good deals on the internet so partly depends on what I can find.
Thanks for the info on suppliers, and the various points of view and the differing angles shared. It is very helpful in sorting through the confusion.
